The process of planing the flat surface of a cast iron workbench involves several key steps. First, manually swing the table and tool holder to determine the depth of cut. For easier operation, the cast iron plate is typically placed on the right side, and the left cutting tool is used for planing.
After manually testing the planer with a straight edge for 1–2 mm, measure the depth of cut using a dial indicator to ensure it’s appropriate. Once the entire surface of the cast iron plate has been machined, stop the machine and raise the tool holder to its starting position. Use a square to check if the processed surface is straight relative to the adjacent surface. If it is, continue planing until the desired finish is achieved.
When making the final cuts into the cast iron plate, reduce the feed rate to avoid chipping or damaging the edges of the plate. This ensures a smooth and precise finish.
