reCool for Static Tooling

March 01, 2015

Following the success of its retrofit reCool coolant-through system for live tooling on CNC lathes, Rego-Fix has expanded the affordable, low-maintenance system to bring internal cooling capabilities to static toolholders on Swiss-style automatic machines.

In as little as 2 minutes, the new static reCool system converts a standard Swiss tooling collet locking nut into a coolant-style nut that employs the new Rego-Fix intRlox antislip nut design. Changing tooling involves simply loosening and removing the locking nut and supply piping.

Implementing and changing through-tool coolant in the restricted confines of a Swiss automatic machine has traditionally required working with coolant plumbing passing through the back of the machine tool block. reCool eliminates the need to work behind the tool block and thereby reduces setup and tool changing time. By sending coolant flow directly to the cutting edge, through-coolant operation benefits tool life and expedites chip removal.

According to David McHenry, engineering and technical manager at Rego-Fix, reCool is much more effective in getting coolant to the cutting edge than spray pipes or nozzles. "When your operations involve extreme speeds, feeds and temperatures, you can quickly and easily enhance your production efforts and reduce your manufacturing costs with reCool," he noted.

Rated at coolant pressures of up to 1,450 psi with a standard hose and 2,100 psi with a braided hose, the static reCool design for Swiss automatic machines replaces standard ER mini-nut types 16 and 20. It works in conjunction with the company's coolant disc systems DS/ER and KS/ER.

Related Glossary Terms

  • collet


    Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.

  • coolant


    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
