Optimized solutions for high‑precision pure copper turning.
Applicable to pure copper (C1020/C1100) machining on Swiss CNC lathes and CNC-lathes.
Diamond-coated carbide UC1, offering excellent wear and anti-welding resistance, is recommended, as tool wear and surface deterioration caused by material adhesion often result in short tool life.

When cutting conditions produce thick chips-such as high depth of cut or high feed – the machined surface may deteriorate due to chip clogging.

Using the cutting conditions shown, chips can be segmented and controlled with AM3 chipbreaker.
When machining at large depths of cut and high feed rate, select CL or ZP chipbreakers to suppress chip clogging.
Stable chip formation may be difficult with a chipbreaker alone; therefore, the use of a Y-axis toolholder combined with high-pressure coolant is recommended.
Even if good chip control is obtained at initial stage of machining, sudden chip entanglement can occur leading to tool wear.
Y-axis toolholder + high-pressure coolant
Chip tangling can be suppressed by Y-axis machining with high-pressure coolant.
