Q Why do CNC router bits break?
A Bit breakage during CNC processing can occur due to several factors. If this problem arises, you can systematically check your machine and process. Understanding the potential causes can help you prevent tool breakage in subsequent operations.
The cutting, engraving, milling, and other operations of a wood router machine are all performed by the bits. Choosing the correct CNC router bits is crucial for improving work efficiency and ensuring precise processing results. While various types of bits exist, here are recommendations for different materials and applications. Keep in mind these are general guidelines, and specific bit selection should be based on the actual processing situation:
· Acrylic Cutting: Single-edged spiral cutters are recommended. Double-edged milling cutters or cylindrical cutters can also be used for thin acrylic sheets.
· Aluminum Machining: Dedicated single-edged aluminum CNC router bits are recommended. Double-edged milling cutters designed for metal can be used for less stringent cutting requirements or harder aluminum sheets.
· Engraving Relief Patterns (Non-metal): Round bottom CNC router bits are primarily used for this purpose.
· Softwood, MDF, Original Wood, PVC, Acrylic Engraving: Single- or double-edged spiral milling bits can be used.
· Metal Engraving: Tungsten steel-coated, metal-specific single- or double-edged milling cutters, and special flat-bottomed bits are recommended.
· MDF, Solid Wood, Multi-layer Board, Plywood Processing: Straight groove milling cutters or double-edged large-flute milling cutters are suitable.
· Jade or Stone Engraving/Carving: Diamond engraving CNC router bits are a good choice.
