Rego-Fix's PG-Cryo Applies Cryogenic Cooling to PowrGrip Toolholder

Rego-Fix has introduced the Cryo-PowrGrip (PG-Cryo), a cryogenic coolant technology based on its PowrGrip system. Produced in conjunction with a European supplier of CO₂ coolant, the product is designed to increase productivity and eliminate the need for secondary cleaning operations, especially for medical parts. The PG-Cryo line is also said to enable high-speed cutting in some of the toughest materials.

Initially created for the medical industry, which requires contaminate-free coolant technology for cleaner parts, the PG-Cryo is an application-specific solution based on standard toolholders that guides the cooling medium directly to the cutting edge. In addition to enabling higher cutting parameters, this toolholder — and the quick dissipation of gaseous CO₂ following cooling — improve surface finishes and chip recyclability while also eliminating coolant disposal and workpiece cleaning, the company says.

Much like with minimum-quantity lubrication (MQL), the coolant lance diameters of the PG-Cryo are engineered for individual applications, achieving optimal CO₂ flow and placement. With metallic sealed collets and cooling CF slots, as well as special HSK coolant tubes, the design is said to prevent CO₂ from pooling inside the holder (where it may cause the spindle to ice over) or on the workpiece itself  (where it might create cold-affected zones).
