Tegara CAT40 1x4 Dual Contact Face Mill Tool Holder 202-6709 P - High Precision Milling for Aluminum, Steel & Cast Iron - Perfect for CNC Machining & Industrial Applications

When you aspire to create one of the most competitive tool holders on the market, the details count. We invest heavily in extensive automation manufacturing and top of the line Mazak and grinding machines while pouring our heart and soul into bringing the tool to life. While not satisfied with just being good, so through customer data and rigorous testing, our R&D team are able to blend over 40 years of manufacturing know-how and real-world feedback to improve the tool holder's design and performance. We optimize our process for both efficiency and accuracy by utilizing Kawasaki robotic arms to load and unload bar stock into the Mazak multi-tasking machine centers. We use SCM420 alloy steel to lay the foundation and case harden to RC 57-59 with a core of RC 34-39 to provide good core strength and maximize wear life. The core creates a dampening effect which reduces vibration in high speed milling to improve surface finish. The AT3 or better taper accuracy ensures 80% or better taper contact with spindle and using Mahr Air/Electronic Gaging for inspection on the taper. We precision grind the arbor surface to <.0002" TIR on a CNC grinder to ensure close run-out tolerance and evenly contact between the face mill pocket and the arbor. We use Haimer laser balancing machines to deliver a tool that can operate flawlessly at 20000 RPM and Mitutoyo or Mahr indicators to check the run out. Taper ground to AT3 or better specification ensures 80% or more contact with spindle to reduce harmonics, improve runout tolerance and deliver consistence performance Flange Contact Precision mill finished from multi-tasking Mazak machine on the flange face to eliminate the 1/8" gap between flange and spindle nose to minimize vibration Inside bore are precision turned to engage a better contact with retention knob's pilot to increase rigidity With simultaneous contact on taper and flange face between the spindle and tool holder, dual contact tooling eliminates the 1/8” gap between the flange face and the spindle nose to increase rigidity, minimize vibration, extend cutting tool tool life, and greatly improve workpiece surface finish at aggressive speed & feed By utilizing DONE IN ONE capability from Mazak Integrex machine with a second turning spindle, all processes from raw bar stock material to final machining in just one machine to improve machining accuracy and streamline production output. To achieve AT3 or better taper contact as an industry standard, our taper surface are precision ground on Shigiya CNC grinder from Japan and taper accuracy is inspected in Mahr air gage. We are not satisfied with just meeting the industry standard, the surface roughness on the taper is maintained to mirror finish.
