About the clamping system "SLH-x"

• For a hollow shank taper (HSK) tool interface (DIN 69893) or direct clamping
• Based on the principle of monolithic preloaded self-locking
• Simple and ultra-compact design with a precise, robust, and maintenance-free application
• Available sizes: SLH-20, SLH-25, SLH-32, SLH-40 and SLH-63

What do you need for simple, safe, and unalterable clamping of tools with hollow shank taper (HSK)?
Nothing more than our springless, self-locking clamping system tool (SLH-x – the springless simplicity).

Problem:
Manufacturers of tool spindles know the typical problems with spring-based automatic taper clamping systems. These include extremely long and complex designs, unsteady, unbalance values and shaft dynamics, fatiguing disk springs, varying clamping/unclamping positions, and very high service costs. In addition, the arrangement of tapered or wedge connections results in widely varying clamping and release positions. In addition, the high surface pressures cause tribological changes with sometimes dangerous changes in the clamping force or operating positions. Last, the current state of the art generally uses a conventional clamping set followed by a locking unit, which tightens clamping stroke changes.

Solution:
To address the above problems, we developed our springless clamping system for high shank taper (HSK) tools with an optional and aerostatic rotary feedthrough. This is based on the principle of monolithic preloaded self-locking. Here, the clamping set takes over both the clamping of the HSK tool and the preloaded and safe self-locking.
