New Tool Designs Power Faster-Than-Ever Cutting

April 23, 2018
Industry veterans often say the makers of machine tools, cutting tools, CAD/CAM software, and other components push each other in an endless feedback loop to deliver ever faster cutting speeds in ever harder materials. Lately it’s the cutting tool manufacturers who seem to be leading the charge. Let’s see what they’re up to.

Big, Heavy, Awkward Parts Need Workholding, Too

April 23, 2018
If you’ve ever seen industrial wind turbine components on the back of a flatbed truck rolling down the highway, you have a good idea of what a large, heavy, difficult-to-handle workpiece is. For example, with a single blade on the GE 1.5 mW turbine being almost as long as a football field, the entire blade assembly weighs about the same as 36 small cars.

When the Going Gets Tough, Tough Toolholders Get Going

April 23, 2018
As machining has evolved, toolholders have advanced to include rigid, secure systems with anti-pullout protection. These advanced systems are needed to take on difficult-to-machine materials, such as titanium and heat-resistant superalloys (HRSA), and accommodate ambitious removal rates and long tool overhangs. Think of them as insurance against tool pullout and breakage—a situation nobody wants.

Shrink-Fit Toolholder Offers Consistency When Setting Tools

April 23, 2018
Shrink-fit toolholding is a simple concept—an induction coil is adjusted and fits over the top of the toolholder. The induction coil heats the toolholder end of the shrinker, expanding the inside diameter, which opens the engagement bore (IDs of shrink-fit toolholders are smaller than the shank diameter of the cutting tool).

Workholding Solutions to Reduce Costs, Increase Throughput

April 24, 2018
At the Nirvana Machine Shop on planet Perfection, every workpiece is clamped to a custom-built fixture mounted on a dedicated machine tool. Each workpiece is dimensionally identical to the one before and the one after. All the fixtures are totally automatic—instantly positioning, clamping, machining, inspecting, and releasing the part with the ultimate precision.

  • Siemens’ Digital Process Chain Cuts Oil Field Rock Bit Down to Size

    April 25, 2018
    DMG Mori’s entry-level, compact DMU 50 five-axis machining center is producing an oil field rock bit from a 440 lb (199.5-kg) 1045 grade steel workpiece, 8″ (203-mm) diameter by 8″ (203-mm) high, for a major upstream oil industry supplier. The result using Siemens full CAD/CAM-CNC digital process chain was better tool life, a higher degree of accuracy, and overall production efficiencies.

    High-Torque Retention Knob Gives Job Shop Spindles The Competitive Edge

    April 25, 2018
    Despite the addition of more than 750,000 CNC mills in the past 15 years in the US, CNC machining job shops often hover at the bottom of the totem pole, where there’s little room for error as most bids are won by a 1–2% price variance.

    Perfect Analogy for Electrical Safety Principles

    April 26, 2018
    Driving to work, deep in thought, pondering the reasons companies use Permanent Electrical Safety Devices (PESDs) in their electrical safety programs, I nearly slammed into the back of a bus stopped at a railroad crossing. With a pounding heart and a rush of adrenaline, it hit me like a freight train—both electrical energy and freight trains yield to no one.

    The Basics of Live Tooling

    April 27, 2018
    Live Tooling, as the name implies, is specifically driven by the CNC control and the turret of various spindle and powered sub-spindle configurations on CNC lathes to perform various operations while the workpiece remains in orientation to the main spindle.

    Better Together: Machinists and Programmers

    April 27, 2018
    Spend enough time on shop floors and you’ll learn about the two different groups of skilled workers that reside there. On one side are the old-school machinists—skilled craftspeople who use their hands, eyes and ears to guide machine tools. On the other side are the programmers and engineers.
