Description
1. This machine is suitable for machining ferrous-metal, non-ferrous metal or part non-metal components with carbide alloy or porcelain cutter, on the machine, cylindrical turning and boring, taping, surfacing, curving, slotting, threading as well as drilling can be carried out roughly and finely.
2. This series machine has universal and CNC types including standard and heavy-duty model.
3. The bed of CNC type is of integrated four-guideway, and carriage guideway is equipped with guard. Bed guideway adopts hardened alloy steel plate and ground.
4. Main drive is driven by D.C motor through two steps mechanism to reach speeds range for spindle, which is through structure and supported by high-precision double-row short cylindrical rolling bearings with adjustable radial clearance and has best supporting diameter and span because of optimized design so as to improve it's swiveling accuracy and static, dynamic rigid.
5. Feed for CNC model is transmitted by A.C servo motor,. High-precision ball screw is adopted for transversal movement, high-accuracy imported rack with hardened and grinding in longitudinal to make carriage feed and rapid travel. ballscrew is adopted for longitudinal in 5000mm, and by double pinion with allowance eliminating-imported rack for over 5000mm. For universal type, concentrated transmission ( by spindle) is adopted to get feed or threading.
6. Carriage for CNC model adopted hydrostatic guideway in its longitudinal direction and equipped with covering.. Bed for universal type uses sliding guideway with steel inserted and low friction pair.
7. CNC system adopts SIEMEN'S or FANUC and semi-closed loop control. Other CNC systems can also be selected by customer's requirement.
8. According to customer's demands, the followings can be provided that are entire-closed loop control, milling and boring, angle-dividing and feed for main spindle, grinding, cooling device as well as the second carriage and its closed loop control device.
