Threaded Lathe Sleeves Maximize Pressure, Coolant Flow

Allied Machine and Engineering, a manufacturer of holemaking and finishing cutting tools for the metal-cutting industry, offers threaded lathe sleeves as a stocked-standard way to induce coolant to newer style holders without rear pipe taps. The sleeves are well suited for job shops that are using aging lathes and are designed for use on machines that do not have the capability to run through-the-turret coolant.

Allied Machine’s goal is to make new cutting tool advancements more accessible to aging machines where high-speed drilling was not thought possible. Across the general machining industry, customers are able to directly plumb in an external coolant line to the back of the sleeve using a standard ½ NPT or ½ BSP pipe fitting. This gives users the option to adapt external high-pressure pumps directly to a turret station to maximize pressure and flow for long/deep holes.

As the manufacturing industry continues to push for drilling solutions with faster penetration rates, drill bodies have evolved to meet these needs with added coolant inlets and outlets. In doing so, the traditional rear pipe tap method of inducing coolant has been lost in many cases. At the same time, with continued innovation comes the risk of alienating those who have built their businesses centered around machinery that has stood the test of time. Because of this, the launch of the threaded lathe sleeves is “just another example of Allied’s continued effort to bring machine shops, small and large, into the new age of drilling,” says John Weniger, Allied Machine and Engineering product manager.
