The enterprise not only to ensure its quality, for the external beauty, also need to carefully maintain.In order to protect the precision parts from the erosion of sweat, air and other components, so that it has been in the factory state, improve the service life.The parts need to be packed in separate, sealed packages after they come out of the oven, and wiped with gasoline or alcohol. This involves working with gloves and blow-drying and then isolating with cotton.
In the processing of precision mechanical parts with various forms, the balance screw is difficult to process, easy to scratch and difficult to ensure the external dimension due to the requirements of its deep opening slot, small width and small tolerance range of size.From the point of view of traditional processing technology, combined with the existing measuring tool, can undertake mold polishing before processing lubrication with open slot, at the same time can also design a kind of clamping is milled, the precision machinery parts processing, can let the balance screw and clamping fixture is processed at the same time, milled and small gap between the workpiece, which not only improve the rigidity of the open slot reduced the risk of deformation, also can make the balance screw to suit the requirements of precision.
Sine rules to measure the introduction of sine bar is taper Angle or lever table with calibration work, relationship between block gauge and trigonometric function of sine a precision measuring tool, by two precise cylinder and a precise working plane body composition, when machining in the belt Angle of workpieces can be precise positioning, when making precision machinery parts processing, put it in homework tablet on sine bar, flat by sine bar across the baffle locates on the workpiece, the final size required for sine bar height and measured workpiece size, the sum of measurement in this way, can strictly control precision parts of shape and size tolerance,
It can accurately locate the position of the error and conveniently obtain the accurate data of the workpiece.
