Tooling and Workholding
Materials, geometries, and coatings are elements in a changing field
Overall, there are two overriding customer needs: reducing cycle time and machine downtime. They want higher feed rates and depth of cut for greater metal removal.
"In the past these needs have been met with bigger tools, but the high cost of tungsten makes that impractical," says Michael Gadzinski, national training manager, Iscar Metals (Arlington, TX). "We are looking at the physical size of tungsten-carbide tools. The soaring cost of tungsten is causing us to rethink and redesign the tools so a smaller piece of material can do the same work as the larger tools. For example, we are evaluating ways to orient the insert inside the pocket so it presents more cutting surface to the workpiece. We are doing a lot of work with milling and grooving tools. For example, you can mount an inset tangentially rather than laying it down flat as we have done for many years. In some cases, this can make the cutting edge up to three times thicker, but at the same weight as the earlier tool."
More secure clamping is also a research area. Iscar researchers have found that many failures are due to inserts moving inside the pocket, prematurely wearing pockets out.
Although machine tool designs have changed, the design of insert clamps has been left untouched. Screw clamps have been the norm for years, but how many impacts can that screw or pocket take before something wears or breaks? "We are designing the pocket so the body of the holder takes more of the force on the insert than the clamping elements," says Gadzinski. "This allows a heavier depth of cut or heavier feed rate, and that may reduce cycle time." Another advance is the Jet-Cut clamping system that allows coolant up to 1000 psi (6900 kPa) to move through the insert.
Trends overall are quite good with aerospace and medical being especially strong markets, according to analysis by Sandvik Coromant Co. (Fair Lawn, NJ). "The US has a very good base for filling the needs of the medical industry, and currently is a world leader in that market," says company president John Israelsson.
To meet that need, Sandvik has done a lot of work on small cutting tools and toolholders. "Small tool designs are often quite different than more conventional tools," Israelsson explains. "For example, there is much more emphasis on sharp edges and corners, as well as lower cutting speeds. This, in turn, requires different coating formulations."
There are different needs for PVD coatings and some CVD coatings adhere better to sharp edges than their predecessors.
Overall, Sandvik's emphasis at IMTS will be to stress new products and how they can add value for customers, with emphasis on turning, milling, and drilling demonstrations.
"CVD coatings have been around for some time and are well established. But there is more potential in PVD," explains Dennis Quinto, technical director, Balzers Inc, (Elgine, IL).
"Over the last 10 years, TiAlNi and TiCNi have been popular. Both are PVD coatings. Currently our Alcrona and Helica coatings, which are based on aluminum chromium nitride, have been doing well," says Quinto. These formulations allow the company to put more aluminum into compositions. The result is higher temperature hardness and better chemical stability, and that translates to higher cutting speeds.
Both work well with difficult to cut aerospace materials such as the Inconels, stainless, and High-nickel allows.
Balzers offers a variety of coatings to meet very specific applications. "The coating must be tailored to the application," says Quinto. "For example, Helica is best with drilling, milling, and turning."
"At Carr Lane Manufacturing, (St. Louis) workholding is continuously evolving to meet the needs of new machining technologies," says Roy Okolischan, vice president. "For example, a significant trend is the increased use of stainless steel tooling components for greater corrosion resistance, especially important with new machining techniques such as waterjet cutting. We are continually adding more stainless steel items to our product line."
Schunk Inc. (Morrisville, NC) has experienced increased interest from the oil industry. And because the wells are operating at higher pressures, the accuracy of drill pipe, particularly the thread, is more critical. And therefore so is workholding. "Some of our chucks can take work 1 m or more in diam," says Milton Guerry, vp and general manager.
"We use wireless sensing of the chuck to ensure proper holding of the pipe. It monitors the chuck's condition, remotely telling the user gripping power and clamp position."
Schunk also offers a spring-actuated mechanical chuck for greater process security.
Another area of advance is toolholding. "We use a new actuation technique in which plastic rings give concentric clamping compression of the tool in a linear action as opposed to drawing a collet into an angle," says Guerry. This design works well for micro parts at high rpm. We can clamp items as small as 0.3 mm in diam."
The upturn in machine tool consumption has caused De-Sta-Co Industries (Madison Heights, MI) to offer its customers' workholding and automation products closely tailored to their operation needs. "Team De-Sta-Co represents our commitment to conducting business in a way that maximizes the amount of resources dedicated to serving our customers' needs," said Patrick Carroll, president, De-Sta-Co. "At its core, the concept involves sharing information across both product lines and geographic diversity, so as to capitalize on the full global scope of our business."
During IMTS 2006, De-Sta-Co will show clamping, gripping, transfer, and robotic tooling solutions for workplace and automation needs, and highlight its 2000 series of horizontal hold-down clamps, which produce 60% more holding capacity than previous models. Also to be shown are new models of pneumatic clamps.
Sumitomo (Mt. Prospect, IL) continues to focus on the automotive industry as well as agriculture, construction, oil, aerospace, medical, job shop, and many other manufacturing industries.
Sumitomo has implemented a new turning system to decrease tooling costs and cost per part by adding the SumiTurn product line. The SumiTurn T-REX insert has six 55° cutting edges as compared to the four cutting edges on a 55° DNMG insert.
The SumiTurn X-Bar is an antivibration steel boring bar that reduces chatter in boring applications with extended overhang.
The coated carbide grade, YB100, will allow customers to increase their speeds due to the high wear-resistance and hardness of the carbide substrate. "Not only does the YB100 decrease production time, it also gives the option to use one insert grade for steels, stainless steels, and cast iron, as the YB100 machines all of these materials effectively," explains supervisor Raul Ratzki.
For drilling, the SMD replaceable carbide tip drill uses a ground, serrated coupling system for an accurate and secure fit between head and body, reducing the possibility of scrapped parts. The SMD drill can accept up to five different diameter tips.
Sumitomo will announce the new 90° shoulder cutting indexable end mill, WEX, at IMTS 2006. The new, hard-nickel-coated end mill is available in end mill and shell mill diameters, featuring a high positive insert design to reduce cutting forces. The WEX will be the first Sumitomo milling product to feature the new line of coated carbide milling grades.
With regard to CBN and PCD tools, coated CBN technology will be another focus of the Sumitomo booth. The coated CBN–SV chipbreaker is designed to eliminate bird nesting and promote chip flow when machining case-hardened material.
Lyndex-Nikken Inc. (Mundelein, IL) sees the state of the industry in a very positive light. "Business is good and all indications point to it staying that way," states Preben Hansen, general manager. "Industries that are showing strong growth for Lyndex-Nikken include automotive, medical, oil patch, and aerospace. With today's more complex machining demands, there is an increased need for special application solutions." Lyndex-Nikken is expanding their offering of the latest technology in angle heads, high spinners, and live tools.
Lyndex-Nikken AngleHeads reduce the number of work setups needed for complex jobs by accessing previously unavailable planes. Reduced setups translate into increased productivity and precision. Right-angle-heads, fixed-angle heads and flex heads round out the company's angle-head offerings.
Nikken's NX HiSpinners increase tooling rpm up to 10 times (up to 40,000 rpm), enabling reduced cycle time. These HiSpinners allow some of the advantages of a high-speed-machining center on existing equipment.
The company has also expanded their line of live tools in either axial or radial configurations. A wide variety of shanks and collets are available.
US manufacturers are picking up on the idea of lighter, high-speed cuts which the Japanese and Europeans have favored for some time. Spindle speeds of 20,000–60,000 rpm require a different mindset when it comes to toolholding, tool design, and balancing. "If you are considering the least expensive product, you will have problems," says Andreas S. Weber, president, Rego Fix (Indianapolis, IN).
For these conditions, this company offers the poweRgrip for high performance, fine machining. Instead of removing or adding spindle weight when balancing, the system has two eccentrically weighted rings. In the balancing operation, the rings are positioned to cancel out any imbalance.
This configuration minimizes TIR and provides a good surface finish. In the latest designs, a number of options have been added, including more tapers and narrow shanks. Size range is also greater with units ranging from 2 to 25 mm.
"Workholding has become increasingly important to the manufacturing process," reports general manager Rick Henderson, Kurt Manufacturing Co. (Minneapolis). "Machinists, process planners, and engineers, through a variety of improvement programs, are continually upgrading workholding applications. The reason is that improved workholding provides an immediate enhancement to productivity and quality, and reduced manufacturing costs.
"There is also a major trend toward the machining of smaller parts made of very hard materials such as stainless and Inconel for aerospace and medical applications. The workholding needed to produce these kinds of parts must be more compact and rigid, with high damping and accuracy capabilities, often to 0.0001" [0.003 mm] accuracies. Kurt's new workholding offerings are machined of 80,000 psi [560 MPa] ductile iron that provides rigidity and stability in very-high-speed machining applications."
Jergens Inc. (Cleveland) is working on two fronts: one to reduce the production costs of their established products, and second to try out new markets. Among the newer areas of activity, according to company spokesman Greg Arnold, is greater interest in hydraulics for workholding, so they are expanding their line in that area. For example, there is now a hydraulic version of their line of vises.
Products that can hold small parts are a growing market, particularly applications in the medical, aerospace, and electronic industries.
Their old standby Quick Lock is now available in a wider variety of sizes.
Kitagawa NorthTech Workholding Inc. (Schaumburg, IL) has seen an increase in the amount of interest in workholding for powder-metal parts. The advantage of using powder-metal parts is getting near-net-shape. So, the customer doesn't have to take as much material off. The types of parts are mostly automotive, for example: automatic transmissions and clutch-pack assemblies. "The tricky part is that these parts are made of tough steel material that is difficult to hold and machine, because they tend to stress relieve, move around, and are never flat or round," explains manager Bill Graham. "Distortion is really the big issue with these parts. Kitagawa combats and overcomes these issues with their specialty chucks and engineering expertise." Industries that Kitagawa is involved with include automotive, heavy equipment, aerospace, agriculture, and high-volume turning.
At IMTS 2006, Kitagawa will feature their standard chucks and will also unveil an e-commerce site where customers can order chuck parts online.
Kitagawa will also feature their specialty chucks including:
- Tecnomors Indexing Chuck: They are the exclusive representative in North America for Tecnomors Indexing Chucks. Tecnomors MD Series Automatic Indexing Chucks are designed for a wide variety of workpieces from pump and valve, automotive and construction industries. The Tecnomors 90° index mechanism utilizes a patented single piston for faster and more flexible operation.
- PW Chuck: For automotive parts manufacturing and suitable for use in rough turning applications, Kitagawa's PW Series Power Wing Chucks offer part length control, high accuracy, and durability. Designed for casting or forging work, the PW Series securely grips tapered parts with draft angles of 20°. A compensating version of the PW Series grips components located off of center locations. Power Wing Chucks are available in three-jaw and two-jaw styles. The two-jaw chuck is suitable for work on square components or on those that are difficult to grip with three-jaw chucks. The chuck is also a sealed chuck to minimize maintenance.
- PU Chuck: Intended for automotive parts manufacturing and suitable for use in precision finish-turning applications, the PU200 and PUE series pull-back chucks grip and pull back material to a fixed stop. These three-jaw power chucks feature component length control, high repeatability, and high gripping forces. This design is also sealed.
- Rotomors Six-Jaw Chuck: Ideal for thin wall, out of round or powdered metal parts, this six-jaw chuck grips at more contact points on the part, eliminating the distortion caused by three-jaw chucks.
"Education in the latest advances in tooling, materials, parts design, and CNC machining is vital to our industry," says Peter Matysiak, president, Emuge Corp. (Northborough, MA). At Emuge Co., collaboration and education are focal points of the company's newly opened Technology Center in West Boylston, MA. This facility is equipped with a Hermle five-axis CNC machining center and an adjoining classroom/auditorium equipped for seminars, demonstrations, and diagnostic sessions."
At IMTS, several new cutting tools will be featured in live machining demonstrations on a Hermle five-axis CNC machining center.
Tapping demonstrations will include the "InnoForm" taps, a series of application-specific cold-forming taps. InnoForm taps feature geometric designs, coatings, and styles, and provide a highly efficient solution for the chipless production of internal threads in a wide range of specific material applications.
There will be demonstrations using their indexable insert thread mills, named Threads-All that are designed for the production of internal threads 1 1/8–M30 on CNC machining centers.
End mills to be demonstrated include the High-Productivity Cutting Tools line designed for challenging cutting applications. The new end mills join a line of solid carbide, PCD, and CBN products.
Emuge will also feature demonstrations of their Thriller product line, including the MoSysTool Holder system.
Command Tooling System's (Ramsey, MN) high-speed machining demo will allow visitors to experience first-hand how much balance matters. Show attendees will see the difference between conventional toolholders and Command's precision-balanced Thermolock holders, balanceable and unbalanceable boring heads, and boring and reaming.
Command's new product demonstrations will cover a wide range of advanced machining capabilities—from fractional and metric sizes of Thermolock holders to a line of URMA reamers and the proven performance of Command's URMA balanceable boring heads.
In addition to the high-speed machining center, Command will also demonstrate its new line of balancing machines and four new styles of heat-shrink toolchangers.
"With the industry's demand for increasingly faster spindle speeds, the importance of precise balance dramatically impacts throughput, spindle life, and finish quality," states Bob Dunlap, vice president.
Command will exhibit four styles of Thermolock holders in a complete range of metric and fractional sizes—including HSK, BT, CT and DIN—and their expanded line of Thermolock extensions featuring a new smaller 3° nose.
Also at IMTS 2006, Command will show its new line of URMA reamers featuring throwaway wafer technology that eliminates regrinding while minimizing setup in high-speed holemaking operations. Visitors will see the difference in speed and finish quality between advanced reaming technology and single-point boring.
Command will also display its line of URMA balanceable boring heads, the VersaMax; the one-pass rough and finish IntraMax; and the microadjustable MicroMax.
Finally, Command will demonstrate their line of balance machines and four new heat-shrink toolchangers.
"There is greater use of manual clamping," says Mark Gordon, Fixtureworks (Fraser, MI) company president. "This is particularly true for those companys involved with moderate production runs, and in those cases where the design is likely to be revised and require a change in fixturing.
"At the same time, we find customers are willing to accept high-cost fixture items, and are moving away from throwaway tools, because they need quality to achieve their product specifications."
One of the company's newer items is a one-touch clamp which requires no bolting action. A single handle movement secures the clamp. Tooling is less costly and build time is less. Fixturing is also more flexible.
"We also offer a range of sizes to meet the need for smaller parts, such as those typical of the medical industry," he concludes.
"With the changes in manufacturing there has been a steady increase of automation in the workplace," explains Peter D. Knowles, president, Hirschmann Engineering USA Inc. (Buffalo Grove, IL). "The use of robotics integrated into the manufacturing process has lead to major changes in manufacturing. While this is not new, there is a greater recognition of what robots can do, especially when supported by software such as the company's Cell Master 5.0 Software, which is a real-time Cell Management System for preparing, organizing, and executing work in an automated CNC machine environment for toolmaking, moldmaking, and job-shop machining."
The new Fixturing System 9000 is a modular point-fixturing system for machine tools developed by Hirschmann. Developed for use with all machine tools, the 9000 is a universal design for all machine tools. Machines can be equipped with a single clamper or multiple Zero Point clampers. Workpieces and pallet-mounted fixtures can be changed quickly to maximize productivity. Starting a new job with the 9000 fixturing system installed takes about 2 min.
The 9000 offers faster machine cycles with higher flexibility. Pallets allow simultaneous loading of a job or workpiece while machining, and there isn't any loss of accuracy when transferring jobs to another machine. — Robert Aronson
Light Activated Adhesive Gripping (LAAG) workholding employs a specially formulated adhesive for holding parts, which is activated by UV. Ceramic pins are fitted into a fixture plate at locations determined by the shape of the workpiece, and a meter-monitored syringe applies an adhesive to the tops of the pins. The part is loaded onto the fixture, and UV light is transmitted through the pins to cure the adhesive. After machining, the part is debonded with a mechanical break. System is said to be suitable for high and low-volume production.
