2 The universal hydro expansion toolholder 3 Narrower tolerances, enormous cost pressure, better quality – TENDO E compact is the answer to growing demands in high- volume machining, which is no longer economically feasible with ER collets, heat-shrinking toolholders, Weldon mounts and lower- quality hydro expansion toolholders. With the TENDO E compact hydro expansion toolholder, SCHUNK combines all high-performance parameters into a contemporary toolholder which satisfies and even exceeds all requirements. TENDO E compact has an impressive price, which makes the switch from mechanical and thermal toolholders to significantly more precise TENDO quality an easy decision. 4 • Up to 300% longer tool life * • Highest torques, now up to 2,000 Nm with dia. 32 mm in dry clamping conditions, 900 Nm with an oil tool shank • Best surface finishes – no chatter marks • Minimized noise emission • Reduced tool costs • Extremely fast tool change without peripheral equipment • Long-lasting run-out and repeat accuracy < 0.003 mm * V erified in a study by the wbk Institute of Production Technology at the Karlsruhe Institute of Technology (KIT). 8

Hydraulic Expansion Technology Your Benefits High torque of up to 900 Nm (Ø 20) and 2,000 Nm (Ø 32) for highest volume machining Due to the compact design, holding forces and a high torque transmission are guaranteed. Your benefit: Highest material removal rate. High radial rigidity for a better part geometry accuracy The optimal radial rigidity resulting from a robust toolholder body, avoids lateral deflection during metal cutting. Your advantage: High part accuracy geometry at the workpiece and the highest material removal rates e.g. 400 cm³/min (25 in³/min) with 42CrM04 (4140)*. * depending on the machine tool and the tool Permanent run-out accuracy of less 0.003 A-B than 0.003 mm – without any fluctuations This assures best surface results due to a uniform cutting action and highest reproducibility. 2.5xD max. 50 mm Your advantage: Safe and precise machining. Excellent vibration damping The hydraulic system absorbs vibrations, assures smooth run- ning, and the best workpiece surfaces. Your benefit: High surface quality, the machine spindle is protected from damage, and service life is increased. 10

Hydraulic Expansion Technology Tool change within seconds, micron-precise without peripheral equipment. Just screw to the dead stop Easy handling. Turn in the actuation screw with an Allen key to the dead stop. The clamping results in a run-out accuracy of less than 0.003 mm without the need for additional peripheral equipment. Your advantage: Time savings due to reduced set-up times and no investment costs for additional clamping devices. All shaft types can be clamped With TENDO E compact all customary tools (Ø 3 to 32 mm) with a smooth cylinder shank as well as recesses according to DIN 1835 Form B, E and DIN 6535 Form HB, HE can be clamped directly with or without intermediate sleeves. Your advantage: No additional costs for new tools. Suitable for HSC / HPC machining – precision-balanced as standard With a balancing grade G2.5 at 25,000 rpm, the HSK-A 63 version for high speeds is perfectly suitable for HPC / HSC machining centers. Your advantage: Perfect for HSK high speed spindles. Maintenance-free The sealed system of the TENDO E compact blocks the penetration of dirt, coolant, lubricants or chips. The clamping area will not be damaged and proper function is guaranteed. Your advantage: Maintenance-free and a long service life. 11

RGG Cleaning Unit Cleaning Unit RGG A sparkling clean Machine Table – all by itself The easiest way to clean. The RGG cleaning unit from SCHUNK is designed for cleaning workpieces and the interior of the machine with air or coolant. It fits in any sealed toolholder with a clamping diameter of 20 mm, and reduced auxiliary process times in every machine tool. A total of six nozzles on the ball head blow out a powerful jet of air or coolant, which is forced from the toolholder mounting via a bore hole in the shank of the cleaning unit. The head can also rotate with the tool spindle when it moves, and can reach all corners of the working area. Advantages: • Low price unit for flexible automation of your machine • Fast, automatic cleaning for a maximum utilization of your machine • Auxiliary process times are reduced to a minimum • Increased safety for the machine operator • Suitable for any SCHUNK toolholder mount (except heat shrink) Sectional functional diagram 1 Locking screws and restrictor inserts to change out the cleaning jet 2 Center bore for intro- 2 duction of cleaning medium 4 3 Outlet openings for producing cleaning jets 4 Clamping diameter for mounting in any tool- holding system 1 Technical Data 3 Description ID Clamping Dead range weight RGG 0308590 20 mm 0.1 kg 15
