Embodiment 1

[0024] Example 1 : Take R1.0×Φ4×15×45 round head milling cutter (hereinafter referred to as "workpiece") as an example:

[0025] Use anhydrous alcohol to clean and remove the anti-rust oil on the surface of the workpiece, then put the cleaned workpiece into a constant temperature drying oven, and dry it within 1 minute, with the temperature controlled at 50-60°C; the workpiece is made of YG6-YG8 hard alloy dentures The bare cutter is the substrate of the diamond-coated milling cutter for the coated pure titanium-ceramic tooth.

[0026] Next, use a pretreatment solution to etch the surface of the substrate in an ultrasonic cleaner for 50 minutes of "pretreatment" and dry it to increase the nucleation density of the diamond film deposition. The pretreatment solution is: use sodium ferrate (Na 2 FeO 4 ), potassium hydroxide (KOH), water (H 4 o 2 ) is prepared according to the weight ratio of 1:2:20;

[0027] Then use W6 diamond micropowder to polish the workpiece pretreated...

Embodiment 2

[0032] Example 2 : Take Φ0.4×Φ4×25×75 carbide milling cutter (referred to as "substrate") as an example:

[0033] 1. Clean with absolute alcohol to remove the anti-rust oil on the surface of the substrate, then put the cleaned substrate into a constant temperature drying oven, dry it within 1.5 minutes, and control the temperature at 60°C;

[0034] 2. Next, use the pretreatment solution to etch the surface of the substrate in an ultrasonic cleaner for "pretreatment" for 60 minutes, and then dry it to increase the nucleation density of the diamond film deposition. The pretreatment solution is: use sodium ferrate (Na 2 FeO 4 ), potassium hydroxide (KOH), water (H 4 o 2) is prepared according to the weight ratio of 1:2:20;

[0035] 3. Then use W6 diamond micropowder to polish the workpiece after the pretreatment in the previous step, so that the substrate forms a frame foundation before coating the diamond film;

[0036] 4. Clean again: use acetone + absolute ethanol (3:7 ...

Abstract

The invention discloses a preparation method of a milling cutter with a diamond coating for processing pure titanium porcelain teeth and zirconium dioxide false teeth. The preparation method comprises the following steps of cleaning, drying, performing pretreatment, polishing and grinding a workpiece, nucleating by a hot wire CVD (chemical vapor deposition) device, growing and depositing a coating diamond thin film. According to the preparation method disclosed by the invention, the phenomena of difficult cutting, fast abrasion of the cutter, blade breaking, blade sticking and the like of a titanium alloy, zirconium dioxide and other difficult-to-process materials in cutting processes can be eliminated.

Description

technical field [0001] The invention relates to the field of denture (denture) processing cutters, and is also applicable to the preparation of cutting cutters for other difficult-to-machine materials such as carbon fiber, glass fiber and ceramics. In particular, it relates to a preparation method of a diamond-coated milling cutter for processing pure titanium porcelain teeth and zirconia dentures. Background technique [0002] At present, less than 1% of the population in my country has dental health up to standard. According to the survey data, 36.4% of people aged 35 to 44 are missing teeth in my country, and 77.89% of people aged 65 to 74 are missing teeth. With the improvement of people's living standards, the emphasis on oral health care is also gradually increasing, and the market demand for denture products belonging to the national second-class medical equipment continues to increase. The denture industry has long been industrialized, and the sales revenue of the ...
