These CNC end mills are ideal for cutting relatively thick materials, but not recommended for thinner or softer materials. Such up-cut CNC milling bits can be used for grooving or slotting, for upward chip evacuation and best finish on the bottom side of the part. Up cutThe up-cut CNC router tools clear the chips away from the material during processing. But the cut type mainly includes three kinds, up-cut, down-cut and compression cut. They are suitable for a wide range of applications. Major cut types of spiral CNC router bitsSpiral CNC end mills are among the most commonly-used router machine bits. The head of such CNC end mills could be in any shape, so you need to choose this type of router machine bits according to your project designs. They are capable for engraving work of various special forms on many materials. So we often call them big head router bits. Different from common CNC router bits that the cutter head is directly machined from the shank, these CNC router tools have cutter heads welded additionally on the shank. They are actually a kind of tapered router end mills with a big taper angle at the cutter tip. The following will give a general introduction of the types of the most commonly used CNC router tools. Great hardness and abrasion resistance.Ĭlassification of CNC router bitsOn the basis of the tip shapes, the CNC router bits can be divided into many types and each type has specific functions.So the CNC router cutter shall have certain characteristics to endure the high temperature, high speed and high cutting force situation. They are designed to carve or engrave the materials to realize 2D patterns or 3D designs.įeaturesThe CNC router bits are subjected to high pressure, high temperature, strong impact and vibration when cutting or engraving materials. They don’t have side edges, so they can’t mill horizontally.ĬNC milling bits, also known as CNC carving bits, CNC end mills or engraving router bits, can cut or move across the surface of the workpieces. CNC drill bits and CNC milling bits.ĬNC drill bits are usually used for pre-drilling holes for screws. TypesBased on the processing method, the CNC router cutters fall into two categories, i.e. CNC router bits of different types can achieve different processes. What are CNC router bitsCNC router bits are the tools installed on CNC routers to cut and engrave workpieces, and also called CNC router tools, CNC router cutters, router machine bits, CNC engraving bits etc. If your projects involve not only cutting work, but also 2D and 3D engraving, pocketing, etc., what kind of CNC router cutters should you choose? What should you consider when buy and use such CNC bits? This complete buyer guide will give you a complete introduction to the CNC router bits, including definition, classification, purposes and precautions for choosing or using them. The CNC router tools fall into many types, and different process requires different tools. Without them, CNC routers can do nothing. They determine the kind of processing you can do and the quality of your finished designs. CNC router bits are the most critical tools for CNC routers realizing cutting, engraving, pocketing and other processes.
