Product Description
Main features of the machine tool
■The machine tool is suitable for the mass production of shaft-type parts.
■This machine tool is equipped with either a Siemens 828D or a FANUC/Oi-TF/G CNC system (other brands of CNC systems can also be configured according to the user’s requirements).
■This machine tool is equipped with automatic measuring devices from Zhongyuan or Marposs (for end-face measurement and radial measurement) that perform online measurements, enabling a closed-loop, automated grinding cycle to ensure the precision of machined dimensions.
■ Both the grinding wheel head feed and the worktable feed are driven by AC servo motors via ball screws; the ball screws are from a Taiwanese brand (other brands of ball screws can also be configured upon user request).
■ The grinding wheel headstock and worktable guideways are equipped with plastic-coated guideways to enhance their seismic resistance and sensitivity.
■ The machine tool is equipped with either a separate or integrated electrical cabinet (with air conditioning for the electrical cabinet), and features a servo-hydraulic system that is energy-efficient and environmentally friendly.
■ The grinding wheel spindle system can be configured according to user requirements: a. Hydrostatic and hydrodynamic series; b. Hydrostatic and hydrodynamic (heavy-duty) series.
■ The tailstock features ball-bearing linear motion and is equipped with hydraulic or pneumatic extension/retraction functionality.
■ The machine tool is equipped with automatic, quantitative lubrication to ensure proper lubrication of the lead screw.
■ The headstock spindle and tailstock spindle both use a No. 4 Morse taper.
■ The machine tool is equipped with either semi-enclosed or fully enclosed guards to ensure operational safety.
