What Does a Tool Grinder Do?

The tool grinding machine has high precision, good rigidity, and is economical and practical. It is especially suitable for sharpening various small and medium-sized tools, such as reamers, taps, twist drills, reaming drills, various milling cutters, milling cutters, and shaper cutters. With the corresponding accessories, it can grind the outer circle, inner circle and plane, and can also grind samples and molds. Diamond grinding wheels can be used to sharpen all kinds of carbide tools.

Tool grinding machines are necessary auxiliary equipment for metal cutting, and are used to sharpen various metal cutting tools. Due to the continuous improvement of metal cutting processing technology, the metal cutting machine tools have been continuously innovated, which requires new cutting tools, and new requirements for the sharpening of the tools are constantly being raised.

The history of tool grinder manufacturing is very young in the machine tool industry. In the history of more than 100 years of grinding machine production, the production of tool grinding machines has not been paid enough attention in the past. The first universal tool grinding machine was first made by the American Cincinnati Company in 1889. Subsequently, the Norton Company in the United States succeeded in trial production in 1890. Universal tool grinder, but at that time were all driven by gear belt, simple structure and low efficiency. In the past thirty years, with the development of industry and the advancement of science and technology, the production of tool grinders has developed rapidly. Not only have semi-automatic and full-automatic tool grinders appeared, but also CNC tool grinders have begun to be applied. ^[1]

1. First determine the diameter of the milling cutter. If you want to grind an 8MM end mill, then choose an 8MM chuck and lock the milling cutter on the 50D sleeve.

2. Set the angle and swing the milling cutter sleeve slightly 4 ° (the angle of the bottom of the milling cutter is between 2 ° ~ 6 °).

3. Start to grind the bottom surface, such as a milling cutter, align the milling cutter with the grinding wheel, and then grind the bevel of the bottom surface of the milling cutter after completing the tool setting step. After grinding one edge, replace the other edge in order.

4. Grind the center clearance angle of the milling cutter, swing the sleeve to about 10 °, and grind the center clearance angle of each milling blade in turn.

5.Sequentially grind the second clearance angle of the milling cutter

6. Grind the side edge of the milling cutter, use the tip to stand against the spiral groove of the milling cutter, align the grinding wheel, and push the sleeve to grind the spiral side edge of the milling cutter.

According to the above-mentioned universal tool grinder to repair the end mill, you can keep your milling cutter new and solve the problem of milling cutter grinding.

1. Safety precautions should allow professionals with electrician operating licenses to install or repair electrical appliances.

2. Before starting, check if the voltage and frequency on the motor nameplate are consistent with the power supply.

3. Machine tool power plug,

1. If the user cannot be used within one month after purchasing the product, please do antirust treatment regularly. With the difference of regional humidity, the antirust treatment time also needs to be adjusted.

2. Please check the running status regularly for one month. If the surface of the screw rod is polluted by dust and metal dust, please clean it with kerosene before filling it with lubricating oil.

3. The ball screw must keep lubricant at all times. If the product is rusted or damaged without lubrication, we will not be able to list it as a free warranty item.
