In-House Measurement For Bi-Rotary Heads

Generally the method required to verify a four-or five-axis, bi-rotary head machining center involves sophisticated laser interferometers and time consuming machine mapping to define and correct axis deviation from wear or other causes. For most shops, this calibration is done by an outside service.

Grinding Carbide--A Niche Within A Niche

If one must pick a manufacturing specialty, grinding carbide might not be the first choice because it’s perceived to be very difficult. RPM Carbide Die, however, has worked the material for nearly 40 years and, as specializing seems increasingly to be the order of the day, this northern Ohio shop is in a good position to thrive.

Multitasking For Micro-Finishing

Micro-finishing or superfinishing is traditionally a specialized secondary operation. In the shop, it follows grinding or hard turning as a last surface preparation operation. In many cases, the combination of hard turning and micro-finishing can effectively eliminate grinding.

Carbide Worm Screw System Improves Rotary Table Life

Mounted in a horizontal or vertical plane, rotary tables can be used to add fourth and fifth axis capability to conventional three-axis CNC machining centers. This rotary table manufacturer has developed an actuation mechanism that, according to the company, significantly increases the useful life of its rotary tables.

Rolling Threads Has Advantages

With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.

A Tale Of Two Cars

In July, a record run came to an end. Conceived in the 1920s, designed in the 1930s and manufactured continuously since the 1940s, the original VW Beetle is no longer being made.
