PRISMO, the tool grinding toolholder, is now available with manual actuation. It is attached as a substructure to the PRISMO, and allows stationary application at cylindrical grinding machines, tool grinding machines or lathes. This innovative tool grinding toolholder from the competence leader for clamping technology and gripping systems clamps every shank diameter between 5 and 20 mm. With a variable clamping diameter, a threefold prism guidance, and chuck jaws which intermesh into each other, the toolholder achieves an outstanding repeat accuracy of less than 0,005 mm at an overhang length of 2,5 x D, and a tool diameter of 20 mm. Moreover, tube imbalance is almost entirely avoided.

  The set-up, the basis sleeve and the robust design give the toolholder a high rigidity. In order to avoid contamination, and to maintain a permanently high precision, the PRISMO toolholder is rinsed during the grinding operation with clean oil. Independent from the tool diameter machined, the X-axis of the grinding toolholder remains unmoved. All the chuck jaws remain at the identical axial position. Costly additional programming and the danger of a crash due to unconsidered off-set of the X-axis is no longer a concern. The prism toolholder is tested for speeds of up to 2,500 rpm.

                    The TENDO SVL tools with a shank diameter of 6 mm, can be directly clamped without the use of intermediate sleeves, making them highly precise. The TENDO SVL transforms almost every precision tool holder into a flexible tool, perfect to use in confined spaces. The high torque of the TENDO SVL ensures a safe hold of the tool during drilling, reaming and finish milling. Instead of expensive special tools, the use of a TENDO extension is normally enough, and it can be equipped with various standard tools as required. In addition to the established extensions with L₁ dimensions 150 and 200 mm, and the standard diameters of 20 and 12 mm, mountings with an L₁ dimension of 150 mm, and clamping diameters from 6, 8, 10 and 16 mm will be available, in which the tools can be directly clamped or with intermediate sleeves.
