Aren't you having these kinds of problems in cutting (scratch) of surface of metal painted sheet samples?
? Variations in the amount of cutting due to instability of the load applied to the cutter blade.
? Cut depth isn't uniform due to changes in the specimen surface condition.
? Low reproducibility of test results depending on the individual worker because of manual adjustment.
? Work efficiency is poor, and work takes too much time and labor.
? Constant load application mechanism: Applies a stable load to cutter blade throughout the operation.
? Position control slider: accurately controls the cutter raising/lowering position.
? Separate control of load and position: Load adjustment and position control are performed separately.
? Response to changes in surface condition: Maintains a constant load unaffected by unevenness of the specimen.
? Combination of self-weight and adjustable external load: Fine adjustment of the optimum cutting force is possible.
? Supports not only crosscut, but also single cuts (vertical, horizontal) and grid pattern (checkerboard) cuts.
