Mid- and High-Pressure Hydraulic Work Support for Stable Machining

TNE is mounted via its compact threaded body, which is screwed into the fixture plate or block and then connected to the hydraulic line; under pressure, the plunger advances to support the workpiece. It is designed for long service life, with a robust scraper and features that help prevent sticking after long machine stops. In most cases, regular checks of hydraulic fluid cleanliness and system pressure are sufficient for reliable long-term operation.

In many cases, TNE can be used as an upgrade for fixtures that currently use TNC because the main mounting dimensions are compatible. Final confirmation should be done by checking the dimensional drawing and any noted changes, especially for deeper holes and contact bolts, with your KOSMEK contact. Replacements for existing TNC models remain available while stock lasts, and the current TNC series will be phased out as inventory is used up.

The 35 MPa Work Support is being changed from model TNC□□□3 to TNE□□□0. The main body mounting dimensions remain compatible, but some details such as plunger stroke, certain diameters, thread sizes, and spring forces have been updated. When replacing TNC with TNE, you can expect improved support force and potentially better machining accuracy, but you should always check the dimensions marked in the drawing for possible interference or contact bolt compatibility. During the transition period, old and new models may be mixed in one order, and the TNC Work Support will be discontinued as inventory is depleted.

TNE is suitable for mid- and high-pressure hydraulic systems and can reach high support forces at pressures up to 35 MPa, depending on the model. Typical applications include supporting thin-walled parts, large plates, workpieces with varying heights, and components prone to vibration or elastic deformation during milling, drilling, turning, and boring.

TNE builds on the trusted TNC design but delivers about 1.5 to 2 times higher support force in a compact threaded body. It offers higher rigidity, improved environmental resistance, and is optimized for mid- and high-pressure hydraulic systems, making it a performance upgrade for demanding machining.

TNE is designed to support workpieces during machining, especially thin-walled or flexible parts that tend to vibrate, deform, or chatter. It stabilizes the workpiece from below or from the side so cutting forces do not compromise accuracy, dimensional stability, or surface quality.

A work support is a device that stabilises a workpiece during machining to prevent vibration, deflection, or chatter. KOSMEK offers different types of work supports, including pneumatic versions. The TNE series is a hydraulic work support: its plunger advances under hydraulic pressure until it contacts the workpiece, then locks in position to provide rigid support for stable and accurate machining.
