Sinumerik L93 Recessing Cycle – Unlock Precise Grooving on 810/820 T CNC

Sinumerik L93 Recessing Cycle allows machining of grooves longitudinal, face, outside and inside.
Also called L93 Cut-in Cycle.

Sinumerik L93 Recessing Cycle Applications

Sinumerik Recessing Cycle L93 allows machining of

• Longitudinal grooves.
• Grooves on face.
• Outside grooves.
• Inside grooves.

Tool Offset

Both cutting edges of the grooving tool have to be stored in neighboring tool offset numbers(e.g. D21 and D22).
