Core Cutting Wear Parts
Shaping Milling Cutters/Turning Tools: These make direct contact with the wood to cut the handle's profile and are the fastest-wearing components. They must be replaced if the cutting edge chips or wears down-resulting in burrs on the machined surface or dimensional inaccuracies-with carbide materials preferred to extend service life.
Sanding Belts/Grinding Wheels: Used for surface sanding and polishing. Grinding efficiency drops significantly when abrasive grains shed from belts or grinding wheels wear thin; regular replacement is necessary to maintain surface finish quality.
Blades/Cutter Heads: Specialized blades used for cutting off or trimming handles. Replace immediately if the cutting edge slips or if chipping exceeds 10mm in length to prevent damage to the equipment's spindle caused by forced cutting.
Transmission and Support Wear Parts
Spindle Bearings: Subjected to wood dust intrusion and wear from high-speed operation. Replace if sharp, abnormal noises occur or temperatures exceed 75°C to prevent spindle seizure and more serious equipment failure.
Drive Belts/Chains: Prone to slippage or tooth breakage due to long-term stretching and wear. Replace immediately if power transmission fails even after tension adjustment, preventing dimensional deviations in the handles caused by insufficient drive power.
Collets/Chuck Jaws: Components that grip the wooden handle blanks. Replace or regrind if long-term wear leads to slippage, positioning errors, or coaxiality deviations in the finished handles.
