solution to extend the life of the new VMC machines. According to Schuster, “Dependability of the ma- chining center is very important, and using the JMPP High Torque retention knobs should reduce the failures associated with traditional retention knobs. I specifically like the low tightening torque required to seat the retention knob into the tool holder. I imme- diately implemented about 30 of these and plan to use them exclusively on all of my TRAK machines/V- Flange systems moving forward.” HIGH TORQUE / CARBIDE TOOL TEST: Increasingly, the automotive industry is using more carbide tools primarily because they can cut both aluminum and hard materials such as titanium, car- bon, and exotic alloys at high speeds. Carbide tool- ing is expensive and also fragile, so it’s imperative to watch for microfractures which yield poor surface finishes. If a microfracture occurs, the whole tip may disappear and the inserts can be rendered useless. Recently, Sandvik, Inc. (Fair Lawn, NJ), a high-tech and global engineering Group with about 42,000 employees, lent out one of their engineering rep- resentatives to test the best retention knobs for Caterpillar® with a $1,200 solid carbide tool. The specification included: a toolholder, reten- tion knob, tightening spec, proper placement, and then lock it down. The test’s goal was to get the custom carbide tool to run without shattering. A variety of standard retention knobs did not work. When tested with JMPP’s High Torque knobs tightened to their pro- vided torque specifications, it worked every time with no tool shatter. After witnessing the dramatic testing results, the Sandvik rep stated, “The JMPP knobs may be the biggest savings to the industry for the next ten years. They are better, faster, provide unbelievable feeds, and can reduce set up times by 40-60%.” 28 TIPS Magazine • May 2019 V-Flange tooling by design should be the most efficient, precise and cost effective tooling system available. The fact is, a carbide tip cannot vibrate when it makes contact, or it shatters. Essentially, carbide must smoothly enter into the pocket and maintain its position in the pocket or it breaks. Carbide can last a long time with the right chip load and RPM. It could last weeks, but let it vibrate and it could be minutes. JMPP’s High Torque knobs have been prov- en to extend carbide tooling life. HIGH TORQUE AUTO / CONCLUSION: Ultimately, by making a simple change…moving to the High Torque retention knobs, CNC manufactur- ers across the board can eliminate the vast majority of issues, improve their milling operations, and get the best results while saving money. Moreover, this solution creates a real opportunity for U.S. tool shops to grow along with their automotive OEM and Tier One customers in creating progressive tooling cost containment solutions. This High Torque solution is so potent, that JMPP guarantees the results their customers have been realizing on any V-flange toolholder that is made to the AT3 or better taper tolerances. They offer to provide High Torque retention knobs at no charge for testing purposes to any manufacturer willing to provide tracked tool life prior to and post-installation of the knobs. JMPP maintains that their High Torque retention knobs are the only tool that can deliver increased productivity and performance on virtually every V-flange tool used in CNC manufacturing.
