Grinding machines for the manufacture of tools and sharpening tools, such as tool grinders and special tool grinders. Tool grinding machines used to grind various tool cutting edges, cutting tools, etc., are mostly used in general machinery manufacturing plants. Special tool grinding machines for grinding certain types of tools or tools. Mainly turning edges, bit sharpening machines, milling edge grinding machines, broaching grinding machines, hob sharpening machines, tap groove grinding machines, circular shovel grinding machines and caliper grinding machines Wait. The common feature of the tool grinding machine is that the cutting force is small. The grinding wheel diameter is small, and the spindle bearing mostly adopts rolling bearings.
On the tool grinding machine can rotate the grinding head, and the crosstable can use for vertical and horizontal movement. The structural layout of the tool grinder varies depending on the workpiece being ground. The tool grinder is operated manually, but it is also semi-automatic and fully automatic. With the use of diamond wheels and cubic boron nitride grinding wheels and improvements in tool grinding processes. Tool grinding machines for high-speed grinding and electrolytic grinding have emerged.
Now, with the development of CBN technology, China has the ability to develop CNC tool grinding machines. Such as a produced by Beijing Demina, which has high precision, automation, and design and repair complexity. The characteristics of the tool. Moreover, the BT-150HG CBN tool grinder can grind tool is now widely used in production.
Adjustment of CBN tool grinding wheel
When using the CBN tool grinding machine, it is especially important to use and adjust the tool grinding wheel. Then, in order to ensure the surface roughness of the workpiece processed by the grinding wheel, in addition to having certain working experience, the grinding machine should also pay attention to the following aspects:
1. The balance between the spindle motor and the grinding wheel.
2. BT-150HG cutter grinding machine the vibration of the spindle motor has a great influence on the surface roughness of the grinding, so it is necessary to dynamically balance the grinding wheel spindle motor. For the grinding wheel, it needs to balance twice:
First, a rough balance is performed after the grinding wheel is finished with a diamond pen;
Then use the grinding wheel after the oil stone or the finishing wheel to finely repair the grinding wheel and then perform a fine balance.
In the normal case, only the grinding wheel that has been trimmed with a diamond pen can only grind a surface roughness of 0.4 to 0.8 μm on a conventional grinding machine. In order to achieve a roughness requirement of 0.02-0.04 μm for the grinding surface, the grinding wheel must refine and fine-tune twice. The trimming method can one of the following two methods.
Beijing Demina Precision Machinery co., ltd specializes in the production of various types of tool grinder equipment. Our grinder equipment is widely used, with good performance and high efficiency, and is used by many users. Users who need it are welcome to come and buy.
