Cryogenic Cooling with kryoCut

With acp systems' kryoCut technology, cryogenic cooling is integrated directly into the machining process. The system is suitable for internal and external cooling in turning, drilling, grinding and milling centers, supporting the cost-effective machining of difficult-to-machine materials and plastics.

Targeted cooling at the point of machining increases cost efficiency through higher material removal rates, reduces tool wear and improves surface quality. It also enables more stable machining processes, particularly when processing expensive, highly wear-resistant materials.

Benefits of Cryogenic Cooling

kryoCut for Demanding Machining Processes

More Cost-Effective Machining

kryoCut can improve machining efficiency by enabling more stable process conditions and higher feed rates. Cryogenic cooling can make a significant contribution to process optimization, particularly when machining difficult-to-machine and highly wear-resistant materials.

Reduced Tool Wear

Targeted cooling during machining can significantly reduce tool wear and extend tool life. At the same time, kryoCut helps improve the surface quality of machined components.

Clean Cooling Process

The cooling process avoids conventional contamination from metalworking fluids and contributes to an improved working environment. Minimal oil lubrication can be added if required.

The recycled liquid CO2 used for cryogenic cooling is generated as a by-product of chemical production processes and energy generation from biomass. Unlike conventional metalworking fluids, no coolant disposal is required. Potentially hazardous coolant additives, such as bactericides, are avoided, contributing to improved worker safety.

Easy Machine Integration

kryoCut technology can be integrated into existing or new machining centers and CNC lathes. The system supports both external and internal cooling.
