The selection of carving tools is based on the combination of processing materials, carving techniques, and equipment parameters, taking into account efficiency, accuracy, and tool life

    Firstly, select the cutting tool material according to the processing material: cork, density board compatible high-speed steel knife; Single blade milling cutters are used for acrylic and PVC to reduce material sticking; Solid wood hard material, stone priority hard alloy knife, wear-resistant and anti collapse; Metal carving uses tungsten steel knives, which have higher hardness.

    According to the carving process, the knife type is determined: flat bottomed knives are used for flat slotting; Fine lines and small character carving with sharp knives for higher precision; Curved relief ball head knife, fitting the curved surface; Double edged milling cutter for hollow cutting, smooth chip removal; Chamfering and trimming with a slope knife.

    Matching device parameters: Small desktop carving machines use small handled knives to avoid overload; High power spindles can be equipped with thick handled cutting tools to enhance stability; The cutting edge length of the tool should be adapted to the machining depth to prevent tool breakage.

Balancing chip removal and smoothness: Choose large chip removal groove tools for soft materials to avoid chip blockage; Choose thick blade body for hard materials; High speed engraving prioritizes mirror polished blade edges to reduce fuzzing and edge breakage, and extend tool life.
