Embodiment 1
[0015] like figure 1 , 2 As shown, the reamer of this embodiment is processed by using a CNC five-axis linkage grinding machine and independently programming the tool program. The base material is made of hard alloy, and the surface is provided with TIALN-XC coating. Specifically, the reamer includes a shank 1 and a blade 2. The blade 2 is provided with a plurality of side edges 3, and chip removal grooves 4 are arranged between adjacent side edges 3. There is a connected internal cooling hole 5, one end of the internal cooling hole 5 is connected to the water inlet hole 6 provided at the end of the handle 1, and the other end of the internal cooling hole 5 is connected to the drain hole 7 provided in the chip removal groove 4 Connected, the pipeline between the internal cooling hole 5 and the drain hole 7 faces the end of the blade portion 2 .
[0016] During processing, inject cooling water into the reamer through the water inlet hole 6 provided at the end of the shank 1, ...
