When using a double-edge straight slotting tip, ensure the handle is securely clamped and the overhang is kept as short as possible to prevent vibration-induced breakage. The entry must be made in a spiral or oblique manner, and vertical plunging is strictly prohibited. Adjust parameters based on the material: softwood and particleboard require 18,000–24,000 rpm, while acrylic needs 15,000–20,000 rpm. For precision work, climb milling is preferred to ensure smooth cutting surfaces. Depths exceeding 0.5mm should be machined in layers, with each layer no more than 0.5mm, and a minimal final finishing pass. During machining, promptly remove chips, and use air cooling for acrylic to prevent sticking. Reduce feed rates at corners and small characters to avoid tip chipping. Clean the tool slot promptly after use and store it properly to prevent tip damage, thereby extending tool life.
