Double-column coordinate boring: Install motion-hole boring machine tool primary processing, the workpiece mounted on the table with the table along the rail bed for vertical linear movement on the spindle. It's good rigidity, large jig borer are using this structure. The main parameters for double-column coordinate boring work surface width. Zhengzhou professional Henderson mine boring, boring machine processing factory processing taper boring, I plant a load of 20 tons boring 1, 2 sets of boring load 10 tons, welcome new and old customers to negotiate, cooperation! Using common horizontal boring and milling of high precision rotary table with spherical spherical milling works with rules: milling sphere method is generating method, and therefore can get the precision sphere. According to the cross-sectional plane of the surface of the ball is round truncate this principle, when the rotating milling cutter tip trajectory is a circle, the workpiece in the rotary table around its own axis machining boring in with two rotary motion, which can high-precision milling sphere.
