Coupling bolts help with live tooling in lathe applications

These pull bolts fully incorporate Mazak’s specifications and are uniquely manufactured to implement JMPP’s patented High Torque retention knob standards from 9310H material.

Coupling bolts used for live tooling on lathes are subject to relaxation, which occurs due to inadequate pre-loading of the bolts during installation, or to rough or inaccurately machined coupling faces — resulting in misalignment. This misalignment causes excessive vibration, which puts an unnecessary load on bearings, and curtails operation at full power.

In response to a special-order request, JM Performance Products, a manufacturer of CNC mill spindle optimization products, has recently expanded their product offering to include coupling bolts for live tooling on Mazak Corporation CNC lathes. These pull bolts incorporate Mazak’s specifications and are manufactured to implement JMPP’s patented High Torque retention knob standards from 9310H material.

JMPP’s coupling bolts are now available for immediate shipment — eliminating the traditional long lead times for comparable imported coupling bolts for Mazak CNC lathes. Notably, the bolts are aggressively implemented in production across myriad industries including, automotive, medical, and aerospace.

Mazak is a manufacturer of CNC lathe and CNC turning centers. Its coupling bolts are an essential part of a work-holding system — as live tooling in the lathe workpiece moves its 5-10 Axis Multi-Tasking Machining Centers. Given their essential function in these centers, these coupling bolts are typically expensive and have longer lead times from overseas. This issue was addressed by a key Mazak dealer who asked JMPP Plant Manager, Craig Fischer, if they could provide a customized solution that would meet the Mazak specifications.

Fischer, and JMPP’s engineering team, noted that the coupling bolts shared many engineering characteristics of their High Torque retention knobs for V-Flange tooling. Given that JMPP currently manufactures and stocks over 400 different styles of retention knobs, the “coupling bolt challenge” was a good fit.

Mazak Pull Bolts

Mazak is a manufacturer of CNC lathe and CNC turning centers. Their coupling bolts are an essential part of a work-holding system.

According to Fischer, “We quickly implemented our High Torque design into the coupling bolt design specific to the Mazak multi-tasking machines. It’s essentially the same type of holder, so it was just a matter of how the machine holds it in and works with it. On the Mazak machine, you bolt it in via a manual process by putting the screw into the back of it and tightening it. Ultimately, the High Torque design solution solves the same problem of allowing the toolholder to be in the machine without bulging and creating better taper contact. Our 9310H material also delivers higher strength.”

While other machine tool builders require similar bolts for their lathes using live tooling, the Mazak style will be JMPP’s first offering. Fischer said that JMPP is the only retention knob manufacturer of record to progressively respond to the unique modification challenge of the Mazak coupling bolt with a customized solution (based on Mazak’s specs and material) — while incorporating JMPP’s High Torque standard tolerances and design features.

By implementing their patented high torque retention knob design into coupling bolts for live tooling in Mazak’s multi-tasking machining center lathe workpieces, JMPP provides machine distributors several competitive advantages.

In the demanding COVID-19 climate, all US manufacturers will have to bundle more technology in their products to compete — at home and globally. By implementing its High Torque retention knob design into coupling bolts for live tooling in the multi-tasking, machining center lathe workpieces, the JMPP engineering team provided Mazak machine distributors an option with competitive advantages like faster response times and advanced production.

JMPP President, John Stoneback, emphasized that “Ultimately, the Mazak coupling bolt customization project presented us with an opportunity to expand our line of retention knobs and other spindle maintenance products. Customers for these coupling bolts can now realize added machining savings in the form of better finishes, less runout, increased speeds and feeds, reduced machine idle-time, and improved production rates.”
