Cross filing is a filing technique used for what purpose?

• A. Stopped halving joint
• B. Cross filing
• C. Draw filing
• D. Welding

Answer: (B)

Cross filing is used to true and flatten a surface by filing across the workpiece, rather than along its length. This across-the-width action engages more teeth and quickly removes high spots, giving a flatter, more even face and a uniform texture. It’s a finishing step to prepare the surface for final smoothing or assembly, and the resulting cross-hatched pattern can be refined further with lighter filing or sanding. This is different from drawing or hand-welding processes, which are not about creating a flat, true surface.
