At the same time, surface milling cutters for rough milling and semi precision milling can be installed on the two main shafts of the spindle box, and the workpiece can complete rough milling and semi precision milling processing by passing under the milling cutter. This type of machine tool has a high productivity, but requires specialized fixtures to clamp the workpiece. It is suitable for milling the top plane of small and medium-sized workpieces in batch or mass production
Geometric accuracy inspection and adjustment of bed type milling machines:
1. Straightness of vertical movement of the spindle box
1. Definition and tolerance range:
Straightness of vertical movement of the spindle box refers to the inspection of the straightness of the vertical guide rail of the column and the vertical guide rail of the spindle box, as well as the matching condition of the two guide rails.
. The spindle selection of quality milling machine is accurate, and this accuracy is tested within two planes of the horizontal (A) vertical plane and the vertical (B) vertical plane of the machine tool. On a measuring length of 300mm, the tolerance for items A and B is 0.025mm. This accuracy deviation will affect the straightness of the machined surface 2. Inspection method:Function of testing report:
