Rough boring with rough boring heads SW
Full profile rough boring – Application and adjustment instructions
Full profile rough boring permits rough boring with large stock allowances (30 mm and more in diameter) in a single operation, with relatively low drive consumption.
Adjustment instructions for insert holders type WC: • Mount the insert holders on mark "RSS“. • Set cutting edge 2 to the final bore diameter (D2).
• Set cutting edge 1 corresponding to the starting bore diameter, according to the table (column D1). • Both cutting edges must be located at exactly the same height. Use coolant in large quantities.
