Features
1. Main parts are casted with high-strength material and after artificial aging treatment;
2. Vertical milling head can swivel ±45° on the vertical plane and spindle bearing is tapered roller bearing;
3. The guideway pair on X, Y and Z axes are supersonic frequency quenched, precision grinded and scraped;
4. Lubrication system may make forced lubrication on the lead screw and guideway;
5. Sufficient power and wide range of spindle speed; VKM32 can also do high speed cutting with carbide cutter tool;
6. Spindle speed is easy to change with impulse device, and it can brake rapidly and effectively;
7. Important transmission parts are made in alloy steel; easy wear out parts are made in wear-resistant material; the guideway adopts paste plastic craft, which assures sufficient service life of the machine;
8. Three-dimensional motion is controlled by stop block, thus has good security;
9. VKM32 can become four-axis NC knee-type milling machine with NC dividing head.
