Description

  1. The Micron VSG8Plus uses the proven fixed carbide pilot tooling with front mount steering wheel for spindle downfeed. The machine has two modes of operation, Front Wheel for Rapid control feed and Side Knob wheel for Precise Fine Feed
  2. VSG8Plus Spindle powered by 1Hp (0.75kW) High Torque AC Spindle Motor Frequency Invertor to control spindle torque throughout the speed range 400 Rpm This control Gives maximum torque at all speeds resulting in fine surface finish even with the hardest valve seats Found in today’s CNG Engines
  3. VSG8Plus Spherical Centering System With Solenoid Locking, Power Head And Workhead Air Floats Independently in 3axis to insure Fast And Accurate Guide Centering
  4. Micron VSG8Plus machines are manufactured from heavy thick wall cast iron. The all cast iron Rigid platform is precision machined providing superior  Accuracy as compared fabricated steel. Rigidity is vital in producing Optimum Accurate chatter  free valve seat cutting. All Cast Parts Are Flame Hardened and Stress Relived, which Will lead to Repeated Accuracy  and Long Last
  5. Three angle Single Blades Inserts Cuts All three Angles at Once and Produce Accurate Finished Seat With” NO GRINDING” ” NO LAPPING”. They assure exact seat width from Head to Head plus CONCENTRICITY Between Seat and Guide
  6. Spindle Head Tilts to 15 degree on both Sides to accommodate any Guide Axis For Machining of All New Generation Imported and Indian Cylinder Head
  7. Quick Chill Half Turn Nut Offers fast Tooling Change from Modular Wide Selection range of Tooling’s and Spindle Adopters .Also Advance Design of Spindle Adopter Assembly with auto-lift pilot mechanism reduced time to complete job with less runout and Better Concentricity
  8. Dial In Variable Spindle Speed 30 to 400 Rpm Without Stopping the Rotation
  9. Takes Minimum Floor Space to Handle the Complete Range Of Heavy Automotive and Industrial Cylinder Heads
