4-axis CNC milling machine SK6520

The machine is used for milling various cylindrical worms with teeth form of ZA, ZN, ZI & ZK etc, as well as steering screws, ballscrews and Acme screws.In addition, it can chamfer the incomplete thread tooth at either end of the workpiece。 【NC system configuration】 1、FAGOR8055iNC system, controlling 4 NC axes 2、Programmable axes descriptions Axis C: Rotation of work spindle Axis Z: Worktable traverse Axis X: Cross feeding of cutter rest Axis A: swiveling of helix angle 【Working accuracy】 worm accuracy achieved by the machine: P7 (by GB standard)； roughness: Ra1.6μm 【Technical characteristics】 1、The workpiece is clamped between a chuck and center of tailstock, and supported with a steady rest。 2、Milling cutter spindle is driven by AC servo motor, so its speed can be regulated steplessly。 3、Milling cutter is made of cemented carbide material。 4、The worktable and milling cutter rest move on sliding rails, steady and smooth。 5、Helix angle adjusting, swiveling and locking is controlled by machine soft program, very easy and precise。
