Dalian machine tool pallet repair generally restores accuracy by scraping. The so-called "scraping" is a combination of two processes of scraping and grinding. That is, plane scraping - grinding display, then plane scraping - re-grinding display, so reciprocating, alternating cycle, continuous operation. The surface roughness value and shape error of the cast iron plate are gradually reduced; the contact accuracy and geometric accuracy are gradually increased during operation until the specified requirements are met.
Tooling and Force Analysis The fitter holds the flat scraper handle against the tibia while the cast iron plate is being operated. The tool is held by both hands, so that the plane scraper and the cast iron plate are cut to a certain cutting angle and pressure is applied to the cutter head. , so that the plane scraper blade is tight on the plane. At this time, when the human shinbone and the waist give the shank a thrust, the cutting edge cuts into the metal surface of the cast iron plate and the blade cuts the black point of the grinding in the deep forward direction, and then the pressure of the hands is immediately converted into the lifting force, and the blade is quickly lifted. Leave the cast iron plate surface.
After the black point regular lap and the cast iron plate are ground, the surface of the cast iron plate on the convex part is all black spots, and the black points are bright spots, dark spots, and light black spots. These black spots are a variable in scraping. After successive alternating cycles, the black spots are dilute from dense to dense, and from uneven distribution to uniform distribution. The evolution of black spots is also a process of gradually improving surface finish, surface contact accuracy, and surface geometric accuracy. !['Dalian machine tool pallet repair, Dalian machine tool carriage scraping repair - [customer must read]](http://i.bosscdn.com/blog/81/62/71/53809.jpg)
