Mold parts grinding process of attention

Mold parts grinding processing technology

Mold parts processing technology, grinding is relatively simple method, is often used. The finishing of the machined surface (such as machining) by grinding or pressing the abrasive particles on the lap with the relative movement of the workpiece at a given pressure. Grinding can be used to process a variety of metal and non-metallic materials. The machined surface shapes are flat, inner and outer cylindrical and conical surfaces, convex, concave spherical, threaded, tooth surface and other profiles. The general work time is held in a fixed place, so you can extend the life of mold parts, while in the process, there are some small points need attention.

Mold parts grinding Note:

1, grinding with abrasive grain size should be coarse to fine, followed by replacement. In the replacement of abrasive, the grinding process should be completely removed before the grinding, grinding to be carried out to only see the grinding traces so far, red pin thimble to prevent the "relief" phenomenon is very important.

2, the same research can only use the same size of the abrasive, each change the size of the material before the need to thoroughly clean up the workpiece again, in order not to make coarse abrasive or other dirt to the next process, causing grinding surface scratches The

3, each time down a grain size conversion, should be with the previous grinding direction to 30-45 degrees angle grinding. If there is a deep scar, can not only this local position grinding, otherwise it will make this local position of the pit, should be fully trimmed to remove the pit. Easy grinding and easy grinding parts should pay attention to uniform grinding.

Mold parts grinding is mainly to improve the surface finish, processing equipment to streamline, precision is not high, get accurate size and precise geometry. After grinding, red pin thimble parts surface finish increased, so that the parts of the corrosion resistance and wear resistance are significantly improved.
