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.
Read MoreGrinding 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.

Customized software helps this machine tool builder maximize the output of its horizontal machining centers.
Read MoreBigger Cutters For Small Mills
This cutting tool manufacturer has developed a lighter, more compact face milling cutter that is available in 80-mm, 100-mm and 125-mm diameters for 30-taper machines.
Read MoreHow to Choose the Right Tool for Milling Titanium
Milling titanium is different from other metals because of the risk of heat build-up. Thanks to the metal’s low thermal conductivity, overly aggressive milling may even pose a risk of combustion. With titanium, in other words, there may be more than one reason why the cutting speed can’t be increased. And yet the speed of production still can be increased.

R&D project aims to change grinding from an art to a science.
Read MoreMultitasking 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.
Read MoreFive Sides And One Zero: Shopfloor Programming For Five-Side Parts
A five-side machining program can be thought of as five different three-axis programs stitched together. Does that mean the task of programming a five-side job has to be five times as difficult, or five times as time-consuming?
Read MoreFast Machining With Fewer Tools
Machining centers capable of precise motion at high feed rates can reduce the number of tools it takes to complete a part.
