Machining

When an endmill efficiently makes chips, everybody is happy: the end user, the parts buyer, and the cutting tool manufacturer and distributor. Achieving that by having the tool follow the correct toolpaths and run at productivity-boosting parameters, however, requires an endmill with optimized geometry, substrate and coating.

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.

Table-type horizontal boring mills add versatility to machine shops.

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?

How close do you need to get the coolant nozzle to the grinding wheel? Dr. Jeffrey Badger offers some direction.
