The all new SG90MTS has a MANUALMATIC Touch Screen control similar to previous MANUALMATIC models but now features the proven ACTIV spindle system mounted on triple air float centering system to improve CONCEN accuracy and allow the use of small diameter pilots for small diameter valve seats. Spindle down feed is operated by the steering hand wheel. The table of the machine is mounted on linear slideways to allow effortless IN/OUT adjustment in the Y direction.

  • Light Weight Workhead floats on Base Plate – The new design SG series utilizes a very light workhead that floats independently on a base plate allowing precise centering of the pilot in the valve guide. The base plate moves the workhead from guide-to-guide by a precision ball screw and servo motor. The complete assembly clamps with air pressure for rigid machining.
  • 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. All valve seats in a cylinder head are exactly the same and the SG100XY cuts every seat to the same depth.
  • Cutting Insert Sharpener – Machine Mounted diamond wheel tool sharpener for fast, easy sharpening of multi angle cutting inserts.
  • Electronic Level and Angle Sensor – Digital Readout on the Touch Screen allows different Cylinder Heads to be leveled quickly and accurately.
