Cryogenic machining systems can extend tool life and reduce cycle times

Efficient removal of heat from the tool/workpiece interface is the main route to high-productivity machining. Several conventional methods are available to accomplish that -- dry machining, minimum-quantity lubrication, flood coolant and high-pressure coolant -- but cryogenic machining can be added to the list.

Battling grinding burn

Dear Doc: I battle burn and long cycle times when grinding ODs in bearing. The wheel manufacturer has specified a series of wheel changes to solve the problem, but it means buying a lot of new wheels. What's your take?

Shops have plenty of choices when gripping small parts

Wedge, cam, square and pull-down clamps, micro vises and chucks, hexagons and rounds. These are just some of the workholding options available to shops that mill small workpieces. Finding the right clamps isn't a problem, but how they're utilized may be. This article examines some of the options and provides tips on how to use them.

A CMM can benefit any shop

Introduced in 1959, coordinate measuring machines have become increasingly common over the last 2 decades. The complexity and cost once meant CMMs were only suitable for large manufacturers. Advances in CMM technology and manufacturing techniques have reduced the cost of ownership, and the machines are now found at all types and sizes of shops.

Roll grinding to finish corners

A technique I call roll grinding is used to finish corners to match bend radii. Long weld seams that need to be rounded can be handled using a rolling technique with the disc grinder. It takes a little practice, but once you've mastered it, the results look just like a formed corner.

Measuring with capacitance sensors: General Industry Coverage

Capacitance sensors are noncontact sensors used in machine tools to measure the distance between a noncontact probe and a target sensor. Because the probe does not physically touch the target, capacitance sensors are beneficial in instances where the target surface is moving, such as a rotating spindle, or delicate, such as a silicon wafer.
