Abstract
The utility model discloses a multi-gear plating end milling knife for ceramic, belonging a knife tool in the cutting processing. The multi-gear plating end milling knife for ceramic is a knife body made of metal, and the tooth part of the knife body is coated with diamond mill grains. The knife body is made into a plating milling knife by way of the processing of removing oil, plating bottom nickel, installing the diamond mill grains, plating nickel secondly, etc. The utility model has the advantages of low cost, long service life and high efficiency, and can process the external surfaces and the complex profiles of engineering ceramic parts and can be used for processing granite material. The end milling knife can be arranged on a vertical milling machine with general precision and be used.
Description
The utility model relates to a kind of cutting tool, is specially adapted to the multiple tooth coating end mill(ing) cutter that the milling engineering ceramic material is used.
Engineering ceramic material and the whisker composite ceramic material that was developed in recent years have good mechanical strength and excellent in heat resistance, wearability, chemical stability, in engineering, be applied day by day, but many at present employing diamond wheels grinding, working (machining) efficiency is low, the part of cost height, particularly manufacturing complex shapes is then very difficult.
No. the 12nd, Japan's " industrial materials " the 31st volume, in " process technology-machining of new ceramic " literary composition, milling cutter milling aluminium oxide and zirconic process technology have been reported with DA100 type single-blade diamond blade, this milling cutter life-span is higher relatively, but cost is also high, also should not be used for processing the part with complex appearance.
U.S. Manufacturing Engineering/March 1980, " Skinmilling for the Space Shuttle " literary composition has been introduced anodontia curve coating milling cutter and has been used for the example of roughing space shuttle heat-resistant tile, this cutter roughing efficient height, but be dedicated tool, the scope of application is restricted.
The purpose of this utility model is to make simply the multiple tooth coating end mill(ing) cutter that cost is low for the process engineering ceramic material provides a kind of working (machining) efficiency height, machining accuracy is high.
The multiple tooth coating end mill(ing) cutter that the alleged cutting engineering ceramic material of the utility model is used is the cutter hub that is made of metal, tooth portion at cutter hub is coated with diamond abrasive grain coating, for diamond abrasive grain firmly is attached on the cutter tooth, adopts cutter hub oil removing, plating bottom nickle, go up the electroplating technology of diamond abrasive grain and secondary nickel plating.This end mill(ing) cutter can be on the vertical knee-type milling machine of general precision, carry out the wet type milling with the upmilling method, effect is splendid, the outer surface of process engineering ceramic part and complicated surface (as groove, inclined-plane or forming surface) expeditiously, and the cutter hub diameter can change according to the processing situation.
Embodiment of the present utility model is as shown in drawings:

The prescription of electroplating process and electroplate liquid is as follows:
The first step, the cutter hub surface must be through oil removal treatment before electroplating, and it is that current density remains on 20A in 25% the sulfuric acid solution that cutter hub immerses concentration; In second step, plating bottom nickle, cutter tooth partly immerse in the solution of preparations such as nickelous sulfate, cobaltous sulfate, boric acid, and wherein nickelous sulfate is the 30%-40% of electroplate liquid weight, and current density is 0.2A, and end nickel layer thickness is 0.02-0.04mm; In the 3rd step, last diamond abrasive grain has plated the cutter tooth of end nickel and has partly imbedded in the mould that diamond abrasive grain is housed; The 4th step, secondary nickel plating, the cutter tooth cutting position nickel plating of first-class diamond abrasive grain, current density is 0.6-0.8A, thickness of coating is 0.12-0.16mm, the water flushing of plating back.
The multiple tooth coating end mill(ing) cutter cutting effect that uses the alleged cutting engineering ceramic material of the utility model to use is as follows:
The machined material characteristic:

Machining condition:
Cutting speed: 70-190m/min
Cutting-in: 0.5-1mm
The amount of feeding: 20-160mm/min
The wet type cutting, cutter external diameter φ 85.
Working (machining) efficiency:
1.8-12.8 centimetre
3/ minute, for the 3-8 of grinding doubly.
Surface smoothness:
Amount of feeding U
f=20mm/min, rotation speed n=900-1400rpm
Cutting-in a
P=0.2mm, Ra are all less than 0.8 μ m
Optimum Ra=0.2-0.22 μ m
Cutter life:
70 of the aluminium oxide parts of processing φ 70,30 of zircite parts, the cutter tooth wearing and tearing are very little, still can use for a long time.This end mill(ing) cutter also can be used for processing grouan material.
