Boring special plate Accuracy: special flat boring standard verification procedures according to national implementation, namely 0,1,2,3, five levels of fine plane. Boring special accuracy is generally a flat face boring machine-specific maximum length of the entire root plate up to 8 meters long, 0.37 meters wide, flat and boring machine dedicated rail are subject to stringent aging boring flat special special boring machine-specific user-tailored weight plate, special plate type boring machine, boring machine dedicated flat specifications. boring machine Main technical parameters of special flat and accuracy parameters: 1, boring special flat work surface should be flat with rust, scratches, bumps and other defects affecting the appearance of using .2, boring special flat work surface should be flat with sand holes, pores, cracks , such as slag and casting shrinkage defects of the casting surface should be thoroughly clean sand, and the surface smooth, solid paint, repair the tax side should blunt .3, dedicated boring flat plate in the opposite sides of the surface, the handle should be installed or lifting position of the set, screw holes or cylindrical holes should be considered when setting the location to minimize the lifting lifting caused by the deformation of .4, boring flat plate shall be subject to special handling and stability to the magnetic .5, boring special flat panel face hardness should be HB170-220 or 187-255 .6 between the main test items A, boring special plate material and surface hardness. B, shape of the position tolerance, with the nominal size, vertical tolerance. C, appearance. D, plane degree. E, exposed spots. F, the amount of surface fluctuations. G, face to allow deflection. H, surface roughness, .7, .3-level precision parameter does not provide access to flat spots requires special boring machine .1 level panel to request access to the number of spots 25 × 25mm in any plane not less than 20 points .2-level panel to request access to special boring machine the number of spots 25 × 25mm in any plane not less than 12 points.
