Point legend according to drawing image:

1) Clamping screw: The clamping screw is used to actuate the clamping piston. Clamp the clamping screw to dead stop using an Allen key. A torque wrench is not needed.

2) Clamping piston: The clamping piston compresses the hydraulic fluid into the oil chamber system.

3) Expansion sleeve and oil chamber: The expansion sleeve evenly expands against the tool shank. The tool shank is centered first and then clamped powerfully and uniformly over the entire surface during this clamping process. When the chamber system is filled with hydraulic fluid, it has a damping effect on the clamped tool. Wear on the cutting edge is minimized and service life increases by up to 40%.

4) Base body: The machine-side interface is located on the base body.

5) Length-setting screw: For fast and easy tool presetting

6) Tool: The tool is centrically clamped to the center axis – highest run-out and repeat accuracy of < 0.003 mm.

7) Dirt groove: The enormous clamping pressure of the TENDO E compact hydraulic expansion toolholder creates a displacement of oil, grease, or grease residue into the dirt groove, whereby the clamping surfaces remain dry.

The hydraulic expansion tool holder TENDO E Compact represents technological excellence for milling, drilling, boring and threading operations. Thanks to its innovative hydraulic expansion technology, it guarantees up to 300% longer tool life compared to traditional systems, as demonstrated by tests conducted by the prestigious wbk Institute of Production Science at Karlsruhe Institute of Technology (KIT).

Designed for exceptional performance, this tool holder combines high torque transmission with a compact construction, ideal for the most demanding machining applications. Its ability to generate superior clamping forces translates into unparalleled stability during cutting operations, even under the most critical conditions.

One of the key strengths of the TENDO E Compact is its standard fine balancing, making it perfectly suited for high-speed machining centers and HPC/HSC applications. With G2.5 balancing grade at 25,000 rpm, it ensures constant and repeatable precision, maintaining concentricity within 0.003 mm.

Operational flexibility is another key feature: through the use of grooved or sealed intermediate sleeves, it's possible to work with tools of different diameters without compromising machining quality. Moreover, the exceptional vibration absorption capability minimizes micro-chatter, improving workpiece surface finish and protecting the machine spindle.

The hydraulic clamping system of the TENDO E Compact is designed to be simple and fast: just insert the tool and tighten the screw with a hex key, without requiring any additional devices. This translates into significant time savings during tool changes and reduced operating costs by eliminating the need for additional clamping equipment.

Integrated collection grooves ensure dry clamping surfaces by effectively removing residual oil, grease or lubricant. This intelligent design helps maintain precision and reliability over time.

For maximum compatibility, the TENDO E Compact perfectly combines with TENDO SVL and TRIBOS SVL extensions, offering a complete solution for every machining need. Its high radial stiffness prevents any lateral deflection during machining, ensuring impeccable form accuracy and optimal material removal rates, as demonstrated by its ability to remove up to 400 cm³/min in difficult materials like 42CrMo4 steel.

With the TENDO E Compact, tool changing becomes a quick and precise operation that doesn't affect process stability. Simply insert the tool, tighten the screw and start working with maximum confidence. The result? Increased productivity, reduced costs and superior machining quality day after day.

Choosing the TENDO E Compact means investing in advanced technology, reliability and performance - all in one system designed to simplify your work and maximize results.
