The requirements of precision mechanical parts for grinding machines mainly include the following aspects:

What are the superabrasive processing requirements for the machining of precision mechanical parts? In fact, the superabrasive grinding wheel in the processing of precision parts puts forward some requirements for the grinding machine, and the grinding is carried out on the superabrasive grinding wheel grinding machine. The requirements of super-hard grinding wheel grinding for grinding machines mainly include the following aspects:

In the process of precision parts processing, enterprises must not only ensure the quality, but also carefully maintain the external beauty and generosity. In order to better ensure that precision parts are not corroded by sweat, gas and other components, they are always in the factory state and prolong their service life. When packaging the part after release, a separate airtight packaging method must be used. At the same time, the scrubbing must be carried out with gasoline or ethanol, and the work requires gloves to work and dry, and then use cotton wool for protection.

In the processing of various mechanical parts, the balance screw is very difficult to process due to its deep groove, small overall width, and small tolerance range of specifications and dimensions. . to guarantee size. From the perspective of traditional processing technology, combined with the current measuring tools, the mold shell can be polished and grooved before processing; the balance screw and the mold sleeve can be processed at the same time, and there is a small gap between the mold sleeve and the product workpiece. It not only improves the stiffness of the slot and reduces the probability of deformation, but also makes the precision of the balance screw higher.

This standard refers to points, lines, and areas used to clarify the geometrical associations between geometrical elements of a manufacturing target. For the machining of mechanical parts, the standard is to clarify the points, lines and surfaces on which other points, lines and surfaces on the part are based. In the design scheme and production process of equipment parts, the selection of points, lines and surfaces according to different regulations is one of the key elements that directly affects the machining performance of parts, the specifications between surfaces, and the accuracy of parts. According to different functions and places of use, standards can be divided into two categories: design scheme standards and processing technology standards.

1. The grinding machine should have high precision. The radial circular runout should be <;0.001mm, the axial circular runout should be <;0.005mm, and the spindle bearings are mostly dynamic and static pressure bearings or dynamic and static pressure combined bearings, or static pressure bearings to ensure the precision machinery required for precision grinding. Part accuracy.

2. The grinding machine must have sufficient rigidity, high stability and low vibration. The stiffness of the machine tool will affect the stability and vibration resistance of the grinding process, thus affecting the durability and service life of the superhard grinding wheel, as well as the grinding quality. Generally speaking, the stiffness requirements of machine tools are higher than that of ordinary grinders; the stiffness is about 50 higher.

3. It is required to have a good feed system, high precision, uniform and stable speed, wide speed range, high speed to ensure productivity requirements, low speed to ensure grinding size, shape accuracy and surface roughness requirements . Generally, the minimum longitudinal feed rate should be 0.lm/min or less, and the minimum transverse feed rate (grinding depth) should be 0.001-0.0005mm/8t (st^single stroke). Changzhou Precision Machinery Parts For grinding with micro-powder grinding wheels, the match between the infeed speed of the grinder and the size of the abrasive grains should be considered.

4. The dressing of the superabrasive grinding wheel should be considered. The dressing of the superhard grinding wheel will involve the needs of some special devices, working fluids and dressing parameters, which will enable the machine tool to be re-installed.

5. All moving parts of precision parts processing machine tools, such as the rotating part of the main shaft and the feed motion guide rail, should be reliably sealed to prevent the entry of superhard abrasives and cause serious wear.

6. Entry causes serious wear and tear. There should be a perfect grinding working fluid processing system to ensure the cleanliness and function of the grinding working fluid, without affecting the roughness of the machined surface, and preventing unclean grinding work beans from wearing off the moving parts of the machine tool.

7. The grinding of super-hard abrasive grinding wheel requires small vibration. The machine tool should be placed on an anti-vibration foundation, and corresponding anti-vibration and vibration isolation measures should be taken. For example, the grinding wheel should be finely trimmed and balanced, and the anti-vibration pad should be added to the contact between the machine tool and the ground.
