SG10A – Cylinder Head Valve Seat & Guide Machine

Rottler SG10A Cylinder Head Valve Seat & Guide Machine.

General Details

The Rottler SG10A spindle is mounted on a sphere which allows the UNIPILOT to automatically center with the valve guide centerline while the Workhead is floating on air cushions. Once air floating stops and the Workhead clamps, the UNIPILOT and valve guide centerline are maintained while cutting the valve seat.

  •  ACTIVE SPINDLE – Spherical Pneumatic Automatic Alignment System built into the Spindle for fast location of the pilot into the Valve Guide and Accurate Centering (Patent Pending)
  • Air Float Work Head with Foot Pedal Control
  • Heavy Duty Spindle – Diameter 3.150” (80mm) Hardened and Ground with 8” (200mm) of hand wheel vertical travel.
  • Rottler Automatic Tightening and Quick Release Spindle Lock Nut System for One Hand Operation for fitting and removing tooling to and from the spindle – never comes loose!

Gives Best Concentricity
Rottler’s Rigid Precision carbide centering UNIPILOTS are manufactured to less than one tenth (.002mm) tolerance.

Combined with the light weight air float Workhead the SG10A gives perfect centering in the valve guide and the best concentricity of any machine on the market, .0005” per 1 inch of valve diameter (.01mm per 25mm Dia.).

FEATURES

  • CNC Touch Screen Controls – Conversational Touch Screen Control allows simple programming for many cylinder head machining operations such as Seat Cutting, Housing Boring, Guide Reaming, Drilling, Tapping and many more functions.
  • Multi Angle Seat Cutting – Rottler’s Precision CNC Ground Fine Grain Carbide Seat Cutting Inserts are available in many different designs to suit customer requirements, single angle, multi angle or curves and radius shapes are available. Cutting tools are substantially faster and less expensive than grinding, where a different grinding stone is required for each angle.
  • Storage Cabinet – 3 Drawers and Top Tray allows convenient storage of wide selection of tooling available from Rottler.
  • Built in Vacuum Tester – For quick checking of valve seats before removing the cylinder head.
  • Air Float 360 Degree – Rollover Fixture Provides quick loading and easy access to all sides of the head. Quickly levels head using the micro adjust feature. Clamps onto table firmly for chatter free cutting with extremely accurate concentricity centered by a pedal. Fixture floats on an air cushion for quick, easy setup with both hands.
  • Rigid Machine Construction – Heavy thick wall cast iron machine castings and precision machining during the manufacturing process give excellent chatter free valve seat cutting. Heavy duty cabinet/ base extended to the rear for safe handling when machine has to be moved. Recessed toe kick allows more comfortable machine operation.
  • Light Weight Workhead – The SG10A has a light weight workhead for fast and accurate centering for the minimum concentricity. At the same time, the workhead is heavy duty capable of machining large diameter valve seats.
  • Spindle Alignment – Pneumatic system controlled by computer aligns spindle vertically to allow UNIPILOT to easily enter valve guide.
  • Variable Speed Servo Spindle – CNC Servo Spindle Motor controls final speed and number of dwell revolutions then lifts automatically given perfect surface finish results.
  • Electronic Level – Digital Readout for quick, accurate alignment for difficult heads such as canted valve guides.
  • 15 Degrees Tilt – Spindle tilts up to 15 degrees from vertical in both directions , providing quick alignment on all canted valve cylinder heads. Cuts each seat to the exact same depth – a must for today’s computer controlled engines.
  • Automatic Spindle Lock Nut – Patented Spindle Locking Nut system offers automatic tightening of tools in spindle. Won’t come loose when cutting. One hand operations, push tool up and spindle lock nut tightens automatically, ejects tool when loosened.
  • Large Diameter Spindle – 3.150 inch (80mm) diameter heavy duty spindle assures rigidity for chatter free operation. Outer spindle support bearings are adjustable over the whole length of the bearing area, similar to High Precision Boring Bar design giving decades of use.
  • Foot Pedal to Control Air Float for In/Out Adjustment of 360 Degree Fixture during cylinder head setup.
