dle surface, a range of CNC-milling issues are overcome, according to company offi- cials. These include vibration and chatter, poor tolerances, non-repeatability, poor finishes, shortened tool life, excessive spindle wear and tear, run-out, and shallow depths of cuts.
“We needed to get these machines up in one day and JMPP filled the order with our applications engineer onsite,” says Bob Ludwig, Enterprise manufacturing engineer. “These were new machine invest- ments and the previous knobs and tool- holders we used had bulged in the past, so we didn’t want to go down that path again. The assembly was simple, and we’ve used the knobs for more than six months with high efficiency and no problems.”
“We’ve got the machines to handle nearly any material, run size and com- plexity,” he says. “We have a lot of money invested in the tooling and JMPP’s knobs provide better overall finishes, and require less hours and shorter runs.”
Since tight tolerances are essential in high-speed machining, if the toolholder doesn’t fit the spindle precisely, decreased productivity and reduced tool life are inevitable, according to John Stoneback, JMPP president.
JMPP officials note that larger manu- facturing entities have achieved similar results by implementing the retention knobs.
“Bridging this gap of missed productivity can conservatively help job-shop operations achieve a 10 to 20-percent/hr. competitive advantage via faster setups, better feed rates and more rigid tools–reducing tooling cost by 20 to 50 percent or more,” he explains, noting that to aid manufacturers in identifying monetary benefits in con- verting to its retention knobs, JMPP offers a free ROI calculator.
New Waterjet Series Boasts
Increased Speed, Accuracy and Durability
new DMG Mori machining centers, a CMX 1100 and a NHX 6300. They required a quick, full tool-up conversion to JMPP high-torque knobs—30 for the CMX and 60 for the NHX. Notably, the NHX machine leveraged a higher-strength version of the knobs since it was a bigger machine.
Custom Designs (OCD), Pittsboro, IN, serv- ices myriad industrial markets via custom machining and fabrication. Its owner, Mitch Olson, recalls seeking the best tooling solutions to push OCD’s milling machines to the limit, ultimately opting for JMPP’s high-torque knobs.

WardJet has released its X-Series line of waterjet-cutting machines, newly designed to increase speed, accuracy and machine durability. Its components, including the re- engineered crossbeam, are simultaneously lightweight and sturdy, and are instrumental to the improved performance of this series, according to company officials. The crossbeam holds multiple cutting heads, and a variety of aftermarket components can be added to increase machine capabilities.

Longer than traditional retention knobs, JMPP’s patented high-torque retention knobs have a precision pilot to increase rigidity—a relief below the flange forces threads into a deeper cross-section of the toolholder. Hard-turned to ensure pre- cision fit, the knobs are balanced by design with threads cut to start and finish 180 deg. from each other. The knobs meet ANSI, JMTBA, ISO or DIN, and JIS standards.
The X-Series line consists of three models: the X-1515, X-1530 and X-2040, with cutting envelopes of 5 by 5 ft., 5 by 10 ft. and 6.7
by 13.1 ft., respectively. Line options include an

JMPP details a number of fabricating companies that have benefitted from using the high-torque retention knobs. One, Enterprise Welding and Fabricating, Inc., Mentor, OH, is a family-owned metal fabricator specializing in sheetmetal fab- rications featuring core-component parts for large heavy-trucking and agricultural OEMs. In 2017, Enterprise purchased two
All X-Series waterjets ship with newly released Move motion-control software. Developed inhouse, this intuitive waterjet-control program offers a user-friendly experience, according to company officials, and is designed to run on a new, 24-in. multi-touch and water-resistant all-in-one display.
