Grinding machine tool adjustment and concerns of the product quality

Grinding machine tool adjustment and the quality of products interested - 2019 02 - 23 li-ming ( Luoyang remit worker bearing) If you want to good product quality in the dry and to adjust the machine well. For the adjustment of the machine tool is good or not directly affects the accuracy of the product processing, machine tool adjustment is bad not only unable to control product quality, and easy to appear quality accident. Grindery machine tool roughly divided into the categories: plane grinding, cylindrical centerless jig, inner circle centerless fixture, chuck landing mill, vertical mill. Whether above which kinds of machine tools, in the process of adjustment, to ensure the protection of deviation and heterodyne better ( Parallel to the plane to ensure that the disk in heterodyne and poor) Poor, parallel with the stand or fall of the heterodyne directly affect the precision of processed products (you Such as: roundness, vertical differential, taper, finished products, etc. ) 。 Fulcrum in heterodyne is too large will cause the poles and the end of the parts contact area is small, easy to cause stop off live, live, such as cut quality accident. Centerless jig in the process of adjustment, but also pay attention to the adjustment of the support point of view, the support is slightly less than the center of the disk is high in 0 & deg; ~15° Between the two support Angle adjustment in 120 & deg; ~150° Between, eccentricity in 0. 20 ~ 0. 35毫米; Outer circle centerless jig before the adjustment, the support is lower than the center of the disk is high in 15 & deg; ~32° Advisable, between two support in 90 & deg Angle; ~116° Between, eccentricity in 0. 25 ~ 0. 45 mm ( Eccentricity can do slight adjustment according to the size of the parts size) ； For machining thin wall products of two support Angle can be appropriately adjusted a little bit small, but must & ge; 90° , but there is also a little eccentricity. Vertical mill when machining parts is very important to find, when at the basic circle by gently knock shock to find is the circumference of the parts, to avoid looking for is in the process of part deformation, and affect the precision of processed ( Thin-walled parts especially more attention should be paid to, if necessary, must carry on the second clamping alignment to ensure parts machining accuracy) 。 Both the size of the support Angle and eccentricity quantity size and the relationship between the precision of parts: too much Angle and eccentricity will cause the workpiece rotates in the resistance is too large, cause: (1) support rapid wear; (2) the resistance of large parts easy to die cut; (3) parts easy to deformation, machining accuracy is bad ( The greater the influence the thinner wall thickness) ； (4) parts in the process of spinning for resistance is susceptible to shock, cause the appearance quality of the product such as a series of problems. Angle is too small and eccentric quantity starts to cause parts easy to live.
