CHEVALIER - SMART-H2440III

Multi-function 2-Axis CNC Surface Grinder

Features

  • This machine uses a large diameter, cartridge–type spindle that is air–cooled, precisely balanced and totally enclosed spindle motor. Providing maximum support to the spindle are six pieces of Class 7 (P4) permanently lubricated, angular–contact ball bearings. This spindle design ensures an extremely smooth surface finish and consistent accuracy.
  • The wheelhead is positioned with a C3–grade ballscrew driven by a servo motor. The wheeelhead guideways are laminated with Turcite-B anti-friction materials and then precisely hand scraped. The downfeed accuracy can be 0.002mm (0.00008”).
  • Pneumatic counterweights are installed in the spindle to eliminate backlash and prevent the premature wear of the elevating screws.
  • The crossfeed slidweay system features a perfect mating of linear slideways, precision ballscrews and a servo motor that provides high torque, speed and accurate positioning with a minimum increment of 0.001mm (0.0001”).
  • The longitudinal slideways feature double “V” configuration instaead of the usual “V” and flat design. The double “V” design improves the structural rigidity and stability of the front base. With Turcite–B anti-friction material lamination of the slideways, smooth and stable travel is consistently maintained during all kinds of machining conditions.
  • Table is driven by AC servo motor and positioned with a high-precision ballscrew, maximizing the control of table speed and position.
