About this manual This manual contains important information for a safe and appropriate use of the product. This manual is an integral part of the product and must be kept accessible for the personnel at all times. Before starting work, the personnel must have read and understood this operating manual. Prerequisite for safe working is the observance of all safety instructions in this manual. Illustrations in this manual are provided for basic understanding and may differ from the actual product design. 2. Warranty The warranty period is 24 months after delivery date from factory assuming appropriate use and respecting the recommended operating and maintenance regulations. Basically tool and machine contacting components, and wear parts (length adjustment screw) are not part of the warranty. 3. Safety instructions 3.1 Intended use The TRIBOS polygonal toolholders are designed for clamping rotationsymmetrical tools or workpieces. –This product may only be used within the guidelines of its technical specifications (see chapter 6). –The product is intended for industrial use. 3.2Not intended use Use of the TRIBOS polygonal toolholder other than as intended includes for instance: –Exceeding the specified technical data during use. –The product is used for heat shrinking. 3.3 Notes on safe operation The maximum speed has to be reduced, if longer, overhanging or heavy tools and extensions are used. 2 CAUTION Risk of injury from tools with sharp edges. •Wear suitable gloves for tool change. 4. Werkzeugwechsel TRIBOS polygonal toolholder always have to be equipped together with an SVP clamping device. –Please observe the operation manual of the individual clamping system when changing the tool or workpiece! –Never exceed the pressure which is indicated on the toolholder! Otherwise it will be deformed and unusable! – The tool / workpiece must be burr- and dirt-free. –Always respect the minimum clamping depth when inserting the tool / workpiece. The axial length adjustment (if available) is carried out with an Allen key via the length adjustment screw. The adjustment range amounts to 10 mm. Never actuate the length adjustment screw with clamped tools. 4.1 Usable shank types Type A Type AB Type B Type E Tools with a plain straight shank according to DIN 6535, shank form HA, and with recesses according to DIN 1835, form B, E and DIN 6535 form HB, HE can be directly clamped. Shanks with recesses impede the balancing quality, clamping force and run-out accuracy of the whole system. Type A with straight cylindrical shank. Shank according to DIN 6535 HA Type ABwith one Weldon flat. Shank Form B according to DIN 1835 part 1 and DIN 6535 HB Type B with two Weldon flats. Shank B according DIN 1835 part 1 4 Type Ewith Whistle-Notch flat. Shank E according to DIN 1835 part 1 A2 and DIN 6535 HE 4.2 Information to the tool change The maximum pressure indicated on the toolholder has to be observed! Some tool shanks are marked and thus have a heightening /layer, which makes tool insertion difficult or impossible. In this case, the material heightening / layer has to be removed. The tool can become stuck in the toolholder as a result of fine particles in the cooling lubricant. In this case, insert a piercer through the rear opening of the TRIBOS polygonal toolholder, and loosen the tool by pushing or gently hitting it with this piercer. Tool shanks with recesses, particularly DIN 1835 form E or DIN 6535 form HE are often deformed, and this often cannot be inserted into the TRIBOS toolholder or may impair the run-out accuracy. The sames applies if the h6-quality of a tool shanks are lower (no torque) or exceeded (cannot be inserted). For clamping shanks form E or HE, the position of the recess to the pressure segments has to be considered! At this shank position in the TRIBOS polygonal toolholder the clamping faces are positioned at the round shank and thus achieve the effect of a “round shank clamp”. The hardness at the tool shank should be min. HRC 50 (Shank stiffness min. 1000 N/mm2) in order to avoid a deformation of the tool shank. If the degree of hardness or stiffness is lower, the compression joint is not properly covered, which will result in a reduced force transmission of the clamping system.

(The ID marked on the toolholder has to match with the one on the drawing.) –Never combine several extensions with each other. –If the minimum clamping depth is not met, there will be a loss of accuracy, the maximum admissible torque will be reduced, and the toolholder can be damaged. –The balancing quality can change due to the use of long, overhanging or heavy tools and extensions. The amount of change has to be individually adjusted to the application, and is in the responsability of the operator. –Additional bores, threads or attachments, which are not offered as a SCHUNK accessory, may only be used subject to written confirmation from SCHUNK GmbH & Co. KG. –Tool clamping and insertion into the machine has to be done by technically qualified personnel only. –Intermediate sleeves GZB can be used for TRIBOS-S and R. Always insert the intermediate sleeves with a fixed backstop. Only use SCHUNK intermediate sleeves! 3.4 Notes on particular risks WARNING When using the TRIBOS polygonal toolholders, there is a risk of injury due to ejected parts. •Use the TRIBOS polygonal toolholders only as intended. •Take appropriate protective measures to secure the danger zone. •Observe the minimum clamping depth. •If longer, overhanging or heavy tools and extensions are used, reduce the maximum speed of the machine/system. 3 4.3 Reduction insert SRE For tool change in the SVP-2, -2D, -3, -4 clamping devices, SRE reduction inserts are required. After insertion of the clamping device, please check if the toolholder and the reduction insert are always jointed to the stop, and that possible clearance of the toolholder will be eliminated by turning it to the right! In order to ensure proper function, maximum wear of the reduction insert should not exceed 0.04 mm.

Care and storage – Clean the locating bore and taper before each use. – Lightly lubricate the entire surface before storing. 6.
