Copper Tube Nozzles

Some Problems with Open Metal Tubes

• Dispersed jet, and air entrainment, especially due to cutting burrs
• Crushing end of tube to create increased pressure and wider jet can give even more dispersed jet
• Adjusted by bending, but will fatigue after several attempts
• Jet aims changes when coolant flows, requires bend compensation
• Need to be placed close to wheel to be effective, but then gets damaged
• Rotation of tube in compression fitting changes aim, unless retightened

Cool-Grind Solder-Fit Copper Nozzles

Flat Solder-Fit Jet

Round Solder-Fit Jet

• Cool-Grind can supply convenient pre-soldered brass on copper nozzle for greatly improved coolant delivery, much reduced flowrate, and higher jet speed.
• Benefits include longer corner retention, cooler grinding, faster throughput, and more tools added to auto-loader.
• The benefits when grinding steel tools are even greater
