Embodiment 1

[0024] Such as figure 1 shown.

[0025] A repairable milling cutter, which is mainly composed of a tool holder 1, a blade attachment frame 2 and a repairable blade 3, the blade attachment frame 2 is fixedly connected with the tool holder 1, and the repairable blade 3 is installed on the blade attachment frame 2. A layer of diamond film 4 is deposited on the repairable blade 3; a groove 2-1 and a threaded hole 2-2 on the side of the groove are opened on the blade attachment frame 2, and the repairable blade 3 is inserted into the groove 2-1 and It is fastened on the blade attachment frame 2 by hexagon socket head screws 2-3. The blade holder 1 and the blade attachment frame 2 can be of a split structure or an integral structure, and the number of blade attachment frames 2 on each blade holder 1 can be selected according to actual needs.

Embodiment 2

[0027] Such as figure 2 , 3 shown.

[0028] An integrated deposition and sharpening repair device for a repairable blade, which is mainly composed of a diamond deposition film studio 5 and a blade sharpening studio 6. The diamond deposition film studio 5 is equipped with a repairable blade 3 for diamond deposition. The workbench 5-3, the workbench 5-3 is installed on the workbench guide rail 6-8, the workbench guide rail 6-8 extends from the diamond deposition film studio 5 to the blade sharpening studio 6, and the diamond deposition film work A door 7 for the workbench 5-3 to pass is provided between the chamber 5 and the blade sharpening studio 6, and a sharpening device 8 is installed in the blade sharpening studio 6. Such as figure 2 As shown, the diamond deposition film studio 5 includes a power supply 5-1, a gas inlet 5-4, a vacuum exhaust port 5-6, a furnace pressure gauge 5-8, a non-deformable hot wire device 5-10 and a gas split distributor 5-11, the power supp...

example 1

[0033] Example 1: the blade grinding equipment of the present invention is used to sharpen each blade, and the sharpening time is 5 minutes, while the traditional milling cutter utilizes an emery wheel to sharpen each blade for 10 minutes, and the grinding equipment of the present invention is used It can save 50% of the sharpening time, greatly improving the efficiency, and the sharpening does not need to be held by the staff, and it is all automatic, which improves the safety of sharpening.

Abstract

The invention relates to a repairable type milling cutter and an integrated repair device. The repairable type milling cutter is characterized in that a diamond film (4) is deposited on a repairable blade (3). The integrated repair device mainly comprises a diamond deposited film working chamber (5) and a blade sharpening working chamber (6), wherein a working table (5-3) on which the repairable blade (3) is placed for diamond deposition is arranged on a working table guide rail (6-8) in the diamond deposited film working chamber (5); the working table guide rail (6-8) is extended from the diamond deposited film working chamber (5) to the blade sharpening working chamber (6); a gate (7) through which the working table (5-3) passes is arranged between the diamond deposited film working chamber (5) and the blade sharpening working chamber (6); and a sharpening device (8) is arranged in the blade sharpening working chamber (6). The repairable type milling cutter has high sharpening efficiency, does not need manual intervention and contributes to improving the cutting quality.

Description

technical field [0001] The invention relates to a milling cutter and its repairing device, in particular to a regrindable milling cutter and its integrated repairing device, in particular to a repairable milling cutter and its integrated repairing device. Background technique [0002] At present, with the rapid development of domestic numerical control technology, the manufacturing technology of domestic CNC milling processing equipment is getting higher and higher. However, compared with the development of CNC milling processing equipment manufacturing technology, the current domestic milling cutter manufacturing technology is still relatively lagging behind. The service life is low, and when milling difficult-to-mill materials, the tool wears a lot, and the edge jumping phenomenon often occurs. After the edge jumping or wear, the tool needs to be re-sharpened. As a result, the tool diameter is reduced, which is no longer comparable to the original tool, resulting in The incr...
