Rego-Fix has launched a cost-effective and efficient attachment for the application of coolant-lubrication liquids through a tool based on an ER collet nut, which is ideal for use on Suhner feed drilling units.

Optimizing the cooling and lubrication effect to help increase chip removal, tool life and performance requires the coolant-lubricant mix in direct contact with the cutting edge of the tool. Namely, for drilling operations, internal coolant has become more and more essential. In the past, the application of an internal pressurized coolant-lubricant mix, especially for quill feed units, presented challenges and complications.

A new approach engineered by Rego-Fix is called reCool, where the coolant-lubricant mix enters the collet from the radial direction and then passes through the tool. It is very simple and effective. Based on this idea, Suhner adapted the reCool principle and designed attachments for the application of internal coolant liquids for its Monomaster and Multimaster families of quill feed drilling units.

Drilling with coolant through the tool applications typically allow for a 20% increase in surface cutting speed, which results in higher chip removal rates and reduces machine cycle time.

This solution allows users to retrofit Suhner quill feed units with internal coolant supply, even on existing machines in a clever, uncomplicated way, thus providing increased benefits in machine efficiencies and production time.

Some of the advantage of reCool are a simple retrofit for existing quill feed units, optimal cooling & lubricating at the tool, up to 20% higher surface speed, good chip removal, optimal lubrication for every tool and nonexistent deflection or dissolving of coolant.

ReCool is compatible with spindle speeds up to 12,000 rpm. It has a coolant pressure of 50 bar / 725 psi and can be used for internal and external coolant application.
