TBRMHSK32A SCHUNK Polygonal tools chuck TRIBOS-RM with HSK32A shanks DIN ISO 12164-1 for HSC machining, clamping diameter of your choise
(Incl. Tax: €512.40)
Il mandrino portautensile poligonale SCHUNK TRIBOS-RM HSK-A 32 è progettato per microlavorazioni ad alta velocità fino a 85.000 giri/min. Il serraggio senza gioco tramite deformazione elastica garantisce concentricità < 0,003 mm a 2,5 x D, elevata rigidità radiale e massima ripetibilità. Con interfaccia DIN 69893, bilanciatura G2.5 e compatibilità con utensili a codolo h6, è ideale per lavorazioni di precisione su centri altamente dinamici.
SCHUNK TRIBOS-RM HSK-A 32 polygonal toolholders are designed for high-speed micro-machining applications where run-out accuracy, radial rigidity and compact design are critical for process quality. This version with HSK-A interface according to DIN 69893 is optimized for highly dynamic machining centers, ensuring stability and reliability even under demanding conditions.
The clamping principle is based on controlled elastic deformation of the internal polygonal profile. Using the TRIBOS SVP device, the clamping diameter is temporarily transformed into a circular shape to allow tool insertion. Once the pressure is released, the holder returns to its original geometry, clamping the tool shank uniformly and without backlash. This system enables a constant run-out below 0.003 mm at 2.5 x D, ensuring high precision and repeatability.
The anchor structure combined with a compact design provides high radial rigidity, which is essential for finishing operations and high-speed micro-machining up to 85,000 rpm. Standard balancing G2.5 at 25,000 rpm (Umax < 1 gmm) ensures safe and stable operation at high rotational speeds.
The holders are designed for h6 tool shanks and include an axial adjustment screw for precise tool length presetting. The design without threaded connections for coolant transfer tubes helps maintain a compact geometry optimized for high dynamic applications.
This solution is ideal for micro-machining, precision machining of small diameters, high-speed finishing and applications requiring excellent surface quality, process stability and maximum repeatability.

TRIBOS-RM HSK-A 32 – Technical features and benefits
| Product description | TRIBOS-RM is suitable for high-speed micromachining operations up to 85,000 rpm. Extremely high concentricity accuracy ≤ 0.003 mm and the rigidity provided by the anchor structure form the basis of these compact toolholder connections and guarantee precision and process reliability during machining. The various sizes are perfectly suited to small highly dynamic machining centers. |
| High radial rigidity | Stability at high cutting forces, good machining performance and therefore faster machining times and higher productivity |
| Small and compact design | Precise and reliable machining |
| Standard fine balancing | Suitable for high speeds with a balancing grade of G2.5 at 25,000 rpm |
| Total compatibility | Ideally combinable with TRIBOS SVL tool extensions |
| Constant concentricity and repeatability accuracy | ≤ 0.003 mm |
| Reduced machine setup times and costs | Fast and easy tool change with the TRIBOS-RM SVP clamping device |
| Excellent vibration damping | Micro blowholes are avoided and better workpiece surfaces are achieved, the machine spindle is protected, tool life is extended and therefore costs are reduced |
| Symmetrical rotation design | The rotationally symmetrical structure minimizes the interference contour and ensures a high rotational speed |
TRIBOS-RM HSK-A 32 – Technology and operating principle
| Technology | TRIBOS SVP actuation devices deform the polygonal shape of the toolholder until it becomes circular, making tool insertion possible. When pressure is released, the toolholder returns to its original polygonal shape, securely and precisely locking the inserted tool shank. |
| Element 1 | Anchor structure – The anchor structure ensures high stability |
| Element 2 | Base body – The machine-side interface is located on the base body |
| Element 3 | Compact design – For high radial rigidity and high run-out accuracy |
| Step 1 | Clamping diameter polygon-similar – By using the TRIBOS SVP clamping devices and the matching pressure actuation, the polygonal clamping diameter of the toolholder becomes round. |
| Step 2 | Clamping diameter becomes round – The tool shank is now easy to insert. |
| Step 3 | Inserting the tool shank – If the pressure on the clamping diameter eases off, then it will assume its polygonal shape again. |
| Step 4 | Tool clamped – The inserted tool shank is process-reliably clamped at a high repeat accuracy. |
