Description

Technical Field

[0001] The utility model relates to the field of milling cutters, in particular to an alloy T-shaped milling cutter. Background Art

[0002] The T-type cutter is a tool installed on a milling machine for milling T-shaped grooves and side grooves of workpieces. The T-type cutter is also called a T-type milling cutter, a semicircular milling cutter, and a keyway milling cutter. It can perfectly process T-shaped grooves and side grooves. It can maintain normal cutting performance at high temperatures.

[0003] At present, the Chinese utility model with announcement number CN212398256U discloses a sidewall milling cutter for machining sidewalls, which belongs to the field of mechanical tool technology. The sidewall milling cutter is a four-edge sidewall milling cutter with an asymmetric structure for the four side edges, which can grind the workpiece in an unequal manner, significantly reduce tool vibration, and increase the front angle to achieve rapid chip removal. At the same time, the groove depth, top width and side taper of the side edge are adjusted to improve machining efficiency. The utility model adopts a new sidewall milling cutter structure, improves the existing sidewall milling cutter layout, size and angle, and has higher machining efficiency and service life than existing tools, solving the technical problems of large aperture and cavity finishing.

[0004] To sum up, although the milling cutter can achieve the function of improving processing efficiency and service life, there are still certain problems in its use. For example, the structure of the milling cutter is a cutter head plus a cutter rod. After the milling cutter is used for a long time, the milling cutter head is prone to wear. When replacing the milling cutter, the entire cutter rod must be replaced together. The cutter head cannot be replaced alone, and the replacement cost is high. At the same time, the length of the milling cutter is fixed. When the depth of the groove to be processed in the workpiece is greater than the length of the milling cutter, the milling cutter cannot be used. Replacing the milling cutter with a new size is not only troublesome, but also a waste of time, and the overall applicability is poor. Utility Model Content
