If it is too loose, it is prone to deviation, and if it is too tight, it is prone to breakage. Optimization of cutting parameters, Speed control: It is recommended to cut stainless steel at a speed of ≤ 3000rpm, and for woodworking boards, it can be increased to 5000rpm. Feed pressure: When cutting thin plates, apply light pressure (≤ 5N/cm ²), while pushing thick plates at a constant speed. Maintenance suggestions, Cleaning and maintenance: After each use, remove any sawtooth residue (wood chips, metal shavings) and apply rust proof grease.
