Drill/Tap Centers Take to Milling

It is reported that, not too long ago, before the current precipitous decline in machine-tool shipments, the number of 30-taper machines that were being manufactured and sold in Japan had surpassed the numbers of 40-taper and 50-taper machining centers.

Tooling and Workholding

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.

The Increasingly Perfected Science of Machining Composites

A 1965 Shelby Cobra 427 shown at the Detroit Auto Show was additively manufactured on a Cincinnati BAAMCI machine by DOE’s Oak Ridge National Laboratory (ORNL), one of seven founding members of the Institute for Advanced Composites Manufacturing Innovation. The Detroit IACMI branch will get $70 million to develop a robust supply chain to improve materials, handling, and machining properties for automotive composites.

Tooling It Up for Composites

From Boeing 787s to new Navy destroyers, fiber-reinforced composites are gaining in use. As production scales up, more-efficient manufacturing remains a focus. One key to that efficiency is tooling for composites. These molds and forms give the final shape to a part, and are often integral to their final curing.

Machining with Robots

Robotic machining technology has advanced to where it poses a serious alternative to metalcutting applications on more traditional machining centers. With the latest robotics equipment and related software, automation suppliers and robotic system integrators are gaining some traction using robots in many material-removal applications previously done only with machine tools.

Edge Finishing — Product Enhancement or Wasted Cost?

Edge finishing is a relatively new term in manufacturing. It’s a new and deeper focus on what many used to call deburring, edge honing, edge preparation, edge prepping, burring, chamfering, or edge blending. Edge finishing goes beyond any of those definitions. Deburring, which is often considered wasted effort by managers, wrongly carries a negative connotation. In reality, deburring and edge-finishing processes add many benefits to parts—they create highly desirable edge quality—the quality most products need.

When Clamps Aren’t the Answer

Workholding techniques using a magnetic field, a vacuum, or an adhesive can be effective alternatives to clamps. When these techniques are used, more part area is available for the cutting tools, thin parts can be held, and initial setup can be fast and simple. Plus, there is a potential for smoother surfaces and a shorter overall production cycle.

Bar Feeders Boost Turning Productivity

One of the most cost-effective ways to obtain the benefits of automation is by adding a bar feeder to a CNC lathe or other bar machine. Costing anywhere from about $10,000 to $40,000 depending on configuration, the devices can add hours of untended operating time for part volumes of a few hundred to tens of thousands.
