3 TOOL STANDARDS MEDIUM TRANSFER CODE TOOL STANDARD A e DIN / ISO 7388 / 1 / 2 type A All OTT-JAKOB clamping systems allow the transfer of diferent types of media, such as coolant and cleaning air. Our product range includes solutions for radial and axial media supply, which are partially based on the speciications of the tool gripper s tool standard. There are mechanisms within the clamping system that enable diferent ways of feed through during rotation and standstill.

9 MEASURING DEVICE HSK STEEP TAPER CONTROL-EDGE Use the measuring device for measuring: the position of the diameter d the measure l HSK CLAMPING SYSTEM FOR AUTOMATIC TOOL CHANGE (DIN / ISO 12164) Studies at the RWTH-Aachen and customer applications have shown signiicant advantages in precision and stifness of the HSK-interface compared to the steep taper interface. The automatic interfaces HSK 25 - HSK 160 are available in 4 forms: Max. allowable deviation of gage dimension measured from the spindle face: ±0,1 mm Higher position accuracy of the tool due to axial face and taper position. Ideal for high speed machining. Easy tool handling due to low weight and dimensions of the short taper. Heavy duty chip removal can be achieved through total stifness of the Interface, high pull forces and the resulting transmittable torque. Form A Is the most common tool standard with internal drive keys. Form B Has external drive keys, a larger lange diameter, and is used mainly for heavy duty chip removal. Form E Without drive key, is used for high speed operation. Form F Has no sealing against coolant and is used mainly in the wood working and plastic industry. Size l Ø d Ød4 Tool Standard All automatic tool clamping systems (Form A / B / E / F) are equipped with the patented OTT-JAKOB gripper geometry. This contour allows to triple the transmittance of the pull force. The forces therefore, occur mainly in the interface area of the spindle.

11 HSK BLACK (TYPE B) HSK BLACK (TYPE B) A shorter tool changing time represents a constant challenge, which even increased with HSC-manufacturing. In response to the increased technical requirements, OTT-JAKOB has developed a new generation of HSK clamping units for automatic clamping systems. MEASURES TO MEET THE INCREASED REQUIREMENTS: BRONZE BUSHING to conserve the coolant pipe. TRANSFER SEAL long-life seal for secure sealing of the coolant pipe. ADVANCED COATING TECHNOLOGY ensures minimum friction, thus guaranteeing high pull forces in the long-term. PERFORMED AN ETENSIVE TEST over 9 million cycles with a cycle time of only 0,13 seconds.

12 HSK BLACK (TYPE BK) HSK 2S (TYPE C) Our HSK-clamping unit type B is also available in shorter versions. (Note: Not to be confused with repair-clamping-units on page 26) The HSK clamping unit 2S (2 Step) is the next generation of OTT-JAKOB clamping units. This clamping unit features a holding function for the tool. When the clamping unit is positioned for tool change, the tools are held by a speciied force in the tool change position. With automatic tool changing, the tool changer must be rigidly designed to withstand the tool pull forces. All types of clamping units of the same size it in the same spindle contour.

13 HSK HIGHER TRANSFORMATION RATIO (TYPE D) COMBINATION OPTIONS HSK Type D is based on Type B. Although having an identical inner contour, this clamping unit ofers a higher transmission ratio. Type D is the right choice, when the spring force is lower than usually due to lack of space, but the normal pull force is required. COMBINATIONS TO FIT YOUR NEEDS Every HSK type allows to combine the higher transmission ratio with either holding or short clamping units. This lexibility enables us to ofer a variety of options and products that are tailored to our customer s needs. Many combination variants have already been realised successfully and are available on demand.

14 REPAIR-CLAMPING-UNITS PSC REGRINDING OF THE SPINDLE SHAFT If fashioning of the spindle inside contour in the tool holder area is necessary, special repair-clamping-units are available. at The polygon shank cone owes its name to its unique tapered polygonal shape. Its basic construction is identical to the HSK interface. The face contact ensures that the tool is held in position securely with no play. Also, PSC transmits high torques force- and form-it without any additional elements, such as drive keys.

Every week Check the packing ring in the clamping unit (visual check) Check the gripper: is it damaged or dirty, is it suicient greased (visual check) Pay attention to: The regrease cycle depends on the loss of lubrication of the clamping unit. Cause for the loss of lubrication: Seal in the clamping cone is defective Type of medium used can desolve grease Cleaning spray from outside directly on the clamping unit etc. Note: METAFLU Moly-Spray No is recommended for a quick regreasing of the clamping unit without gripper-disassembly Nominal size reference length L 1 nominal l 9 js8 (at d 3 ) E ±0.003 (11) E ± (14) A 32 / B 40 / E ± (17) A 40 / B 50 / E ± (21) A 50 / B 63 / E 50 / F ± (26) A 63 / B 80 / E 63 / F ±0.023 (34) A 80 / B ±0.023 (42) A 100 / B ±0.023 (53) A 125 / B ±0.027 (67) A ±0.027 (85) A 50 short / B 63 short / E 50 short / F 63 short 31.5 ± (26) A 63 short 40 ± (34) A 63 short ± (34) A 80 short ± (42) A 100 short ±0.023 (53) A 125 short ±0.023 (67) Every six month or after 200,000 tool changes at the latest In unclamped position: Check dimension gauge E.M.
