These machines are conventional, usually hydraulically operated grinding machines that are used to grind small lot sizes and many times, one piece lot sizes.

Cylindrical tool room grinding machines can be setup to grind round parts, either between workpiece centers or from a workhead driven chucking or collet system. These machines are usually very versatile to grind straight diameters, tapered diameters, shoulders and faces on workpiece parts.

Surface grinding tool room machines are typically equipped with a standard table mounted magnetic chuck with a hydraulically controlled and driven table and wheelhead.

Internal toolroom grinding machines are capable of grinding internal features of a particular workpiece, one at a time. The wheel grinding spindle is hydraulically controlled and can be arranged to remove a certain amount of material on a specific workpiece bore. The workhead can be arranged with a chuck, collet system or workholding faceplate to hold and drive the workpiece while it is being ground.

All of these machine types are usually hydraulically driven or driven with a simple, microprocessor driven feed system. The are controlled by the machine operator to perform the actual grinding operations and require skill and training to perform the grinding operations to the required configurations. Typically, all manufacturing operations have a toolroom machine to accomplish its task.
