CNC milling tools is a rotary cutter with one or more cutter teeth, which is used for milling by CNC machineAnchor icon. During operation, each cutter tooth cuts off the metal allowance of the workpiece intermittently in turn.

How to classify CNC milling cutters?

A. According to the materials used to manufacture milling cutters, they can be divided into:

  • High-speed steel cutting tools.
  • Cemented carbide cutting tools.
  • Diamond cutting tools.
  • Other material cutting tools, such as cubic boron nitride cutting tools, ceramic cutting tools, etc.

B. According to the different structures of milling cutter, it can be divided into:

  • Integral type: the tool and handle are made into one.
  • Inlay type: it can be divided into welding type and machine clamp type.
  • Vibration damping type when the ratio of the working arm length and diameter of the tool is large, this kind of tool is often used in order to reduce the vibration of the tool and improve the machining accuracy.
  • Internal cooling type: cutting fluid is sprayed to the cutting edge of the tool through the nozzle hole inside the tool body.
  • Special types: such as compound tools, reversible thread tapping tools, etc.
What are CNC milling tools?

C. According to the different structures of milling cutter, it can be divided into:

  • Face milling cutter (also known as end milling cutter): there are cutting edges on the circumferential surface and end face of the face milling cutter, and the end cutting edge is the auxiliary cutting edge. The face milling cutter is mostly made into sleeve gear insert structure and indexable structure of blade clamp. The cutter teeth are made of high-speed steel or cemented carbide, and the cutter body is 40Cr. Drilling tools, including drill bits, reamers, taps, etc;
  • Die milling cutter: die milling cutter is developed from end milling cutter. It can be divided into conical end milling cutter, cylindrical ball end milling cutter and conical ball-end milling cutter. Its handle has straight handle, flattened straight handle and Morse taper handle. Its structural feature is that the ball head or end face is full of cutting edges, and the circumferential edge is connected with the ball head edge in an arc, which can feed radially and axially. The working part of the milling cutter is made of high-speed steel or cemented carbide. Aluminum spot welder
  • Keyway milling cutter: used for milling keyway.
  • Forming milling cutter: the cutting edge is consistent with the shape of the surface to be machined.
