| Tendo hydraulic toolholders from Schunk Schunk modified its Tendo to be able to clamp different types of cutting tools with cylindrical shanks directly in the toolholder without using intermediate sleeves. Torque transmission capacity has also been increased by up to 15%. The benefits of the Tendo Hydraulic Toolholders remain unchanged. The clamping of the cutting tool is done by a steel sleeve surrounded by a hydraulic fluid. When initializing the clamping process, an internal piston forces the hydraulic fluid into a cavity surrounding the steel sleeve. The high pressure uniformly forces the sleeve around any cutting tool shank. Cutting tools with different shanks are held with great concentricity of less than 0.002 mm. The enormous clamping pressure displaces oil or grease into the Tendo groove in the clamping bore. Clamping areas remain dry and high torque transmission is guaranteed at all spindle speeds. The hydraulic system also absorbs vibrations inherent in the cutting or grinding processes. The results are high T.I.R. accuracy and repeatability less then 3 microns, tool life extended up to four times, improved surface quality of machined parts. Tendo Hydraulic Toolholders offer precise toolholding solutions for almost every manufacturing process. The toolholders are suitable for high-speed and fine milling, heavy-duty milling, wood machining, high speed machining, internal grinding, boring and chamfering, precision reaming, and precision tool grinding. With Tendo slotted, coolant-proof intermediate sleeves, different shank diameters can be handled with the same toolholder for additional application versatility and tooling cost savings. write your comments about the article :: © 2007 Construction News :: home page |
