Using the Surface Grinder
Operation of the grinder is controlled through the movement of the three handwheels. The elevation handwheel controls the up and down movement of the grinding head. It is this axis that governs the amount of stock removal. Never attempt to remove too much material in one pass. The best results are achieved with multiple light passes.
The longitudinal travel handwheel rapidly moves the table from left to right. This allows the operator to move the workpiece back and forth underneath the grinding wheel.
The cross travel handwheel controls the front-
When grinding, sweep the table back and forth under the wheel in the longitudinal direction until no further sparks emerge from the workpiece, move the table in the cross direction to expose a new portion of the workpiece to the wheel, then take another sweep in the longitudinal direction. Repeat this process until the entire surface is ground. See Figure 43 for an illustration of this process.
Grinding Tips
While every grinding operation is unique, there are a few techniques that apply to most, if not all grinding operations.
