UTS-x (HSK-Tool Holder)

An ultra-low tool run-out at any speed and vibration level are crucial to generate ultra-precision parts with sub-micron shape accuracies and surface finishes under 5 nm Ra. Along with the introduction of our ultra-precision tool spindles it became clear that commercially available tool holders would ruin their properties. Where run-out at the tool was determined to be within 3-10 micron, their balance quality with G8 mm/s at 25,000 rpm as an average was beyond bad. Thus we decided to use or own spindles and machining technologies to generate a tool holder series that suits and supports ultra-precision demands. We created dedicated balancing rigs featuring our spindles to not only balance our tool holders at conditions you could later find in the machining set up, but at nominal speeds and with a tool clamp repeatabilty of under 200 nm.

An these properties you now can also use in your machining solution. With a standard taper interface according to DIN69893-5 and thermal shrinking technology, you can rely on ultra-low vibration levels even at higher spindle speeds, balance qualities 20 times better than the industry standard and a run-out at the tool of under 0.8 micron. Don’t let your tool holder solution ruin your machining results, use our ultra-precision tool holder series UTS-x!

Our UTS-x tool holder series is available for HSK-E 20, HSK-E 25, HSK-E 32 and HSK-E 40 taper interfaces and different tool shank diameters. Becasue thermal shrinking is the only way to get to the stated repeatability values, only carbide tools with shank tolerance h5 or smaller can be used.
