There are about 200 holes on the
aluminum plate to be machined. There are 100 M12 thread holes, and the rest are 15MM through holes. The tolerance is +0.02. Seeking detailed processing technology, is the first hole or first processing plane, how to control the amount of deformation of the plate, if the milling process can not guarantee flatness, on the grinder, then the 2 surfaces to stay 2MM margin? Are there any 15MM through holes that can be used to maintain tolerances, or do they need to be boring?. Great God advice, the best detail. Aluminum so much done before, no experience, if it does it scrapped.Brother, I want to tell you first, the aluminum grinding machine is very rare! Because the aluminum sticky grinding wheel!No money, people are: 1., flying base level, thickness to 26.5 low point! 2. turn the face, press 4 sides, drill rough. The 3. lock bolt is in the hole you hit! Notice here that the lock must be locked one by one! Do you think the workpiece completely tied to lock dead in the fixture, and then processing the thickness to 25.6, the Kong Xian crude drilling reamer locking bolt end processing in place, lock 4. replacement bolts, the original lock bolt hole processing in place! 5., the final flying surface, according to each side of the 0.3 to fly surface, flying surface fixed method, you can use hot melt adhesive or hard rubber mud to fix the workpiece 4 sides and forming the inner hole!The rich person is the vacuum sucker, the base level as much as 26.5, turn over the surface of the vacuum sucker, forming directly!Hope to adopt, typing hard enough!The thickness of 2 to 1. fly in place stress to ensure the flatness of the fitter leveling 0.13 more than the Xicheng pay attention to the protection of the appearance of 4 to ensure the flatness of the fabricated fitter. - this thing must not need to be so high, 100 M12 threaded holes, you still press the map to ensure that ah? Such a large plate deformation, 2 millimeters below the hole can be pressed to doSuch a large plate flatness 0.1 you don\'t need it, basically do not, we used 1000*700 processing board, directly buy imported
aluminum plate, ensure the factory within 0.05, leveling back after processing to find professional leveling company OK, I was also called grinding waste, the deformation of grinding plate will be great, so there is no need to considerOther related question
