Rottler SG80A Seat and Guide Machine
Maximum Cylinder Head Dimensions: 49” length × 14” width × 10” height
Valve Seat Diameter Range: 0.550” to 8.25”
Valve Guide Diameter Range: 0.160” to 1.5”
Power Requirements: 208–240V AC, Single Phase, up to 30 amps
Air Supply: Clean, moisture-free air at ≥90 PSI
- Automatic CNC Control: Provides precise and repeatable seat cutting, counterboring, reaming, and valve guide machining
- Heavy-Duty Spindle: 3.150-inch (80 mm) diameter spindle designed for rigidity and chatter-free operation, capable of vertical travel of 8 inches (200 mm). The outer spindle support bearings are adjustable over their full length for optimal alignment
- 360° Roll Over Fixture: Standard on the SG80A, this fixture allows large 24-valve cylinder heads to be clamped relative to the head gasket fire deck and rotated fully in one setup, reducing the need for multiple fixture setups
- Valve Seat and Guide Range: Supports valve seat diameters from 0.550” to 8.25” and valve guide diameters from 0.160” to 1.5”
- Multi-Angle Cutting Capabilities: Works with CNC ground fine-grain carbide inserts, allowing single-angle, multi-angle, curved or radius-shaped seat cuts that are faster and more cost-effective than traditional grinding
- Floating Workhead with Air Cushion: Enables the workhead to automatically float for fine centering in the valve guides, ensuring high precision and minimal operator errors
- Touch Screen Control: Ergonomically placed for ease of access, it provides feed control, workhead clamping, air float activation, and digital readouts for depth, enhancing operator productivity
