VSG8A Valve Seat Cutting Machine

  • The Micron VSG8A is a high-precision valve seat cutting machine featuring a double air float system, high-torque spindle, and compact design for heavy-duty automotive and industrial cylinder heads.
  • Micro Fine Feed: Dual-mode feed with front wheel (rapid) & side knob (fine).
  • Powerful Spindle: 1HP motor with inverter, 30–400 RPM for hard seat materials.
  • Precision Tooling: Spindle adapter, ball holder, carbide pilot ensure tight concentricity.
  • Rigid Build: Heavy cast iron body, flame-hardened for chatter-free accuracy.
  • Three-Angle Cutting: Simultaneous cutting with superior Ra finish & leak-proof sealing.
  • Tilting Head: ±15° tilt for flexible guide machining.
  • Auto-Lift System: Faster operation, improved accuracy.
  • Compact Footprint: Fits all cylinder heads from cars to trucks.

Description

  1. The Micron VSG8A 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. VSG8A 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. VSG8A Opts Spindle adopter, Ball holder, Fixed Carbide Pilot combination Ring Spring  for lifting Ball Holder result is reduced time to complete job with less runout and Better Concentricity.
  4. Micron VSG8A machines are manufactured from heavy thick wall cast iron.
    The all cast iron Rigid platform is precision machined providing superior Accuracy as compared to 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 insert cuts all three angles at once and produce accurate finished seat with finer Ra Value surface with Leak proof sealing between Valve And valve seat. 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. Advance Design of Spindle Adopter Assembly with auto-lift pilot mechanism reduced time to complete job with less runout and Better Concentricity.
  8. Takes Minimum Floor Space to Handle the Complete Range Of Small Cars, Passenger Car & Pick Van/trucks and Heavy Cylinder Heads
  9. Dial In Variable Spindle Speed 30 to 400 Rpm Without Stopping the Rotation
