Grinding and reconditioning


Tool and Cutter grinder

A tool and cutter grinder is used to sharpen milling cutters and tool bits along with a host of other cutting tools.

View of a typical setup on a T&C grinder
It is an extremely versatile machine used to perform a variety of grinding operations, surface, cylindrical, or for the grinding of complex shapes. The image shows a manually operated setup, however highly automated Computerized Numerical Control (CNC) machines are becoming increasingly common due to the complexities involved in the process.
The operation of this machine (in particular the manually operated variety) requires a high level of skill. The illustrated set-up is only one of many combinations available, the huge variety in shapes and types of machining cutters requires flexibility in usage. A variety of dedicated fixtures are included that allow cylindrical grinding operations or complex angles to be ground. The vise shown can swivel in three planes.
The table moves longitudinally and laterally, the head can swivel as well as being adjustable in the horizontal plane, as visible in the first image. This flexibility in the head allows the critical clearance angles required by the various cutters to be achieved.
