Quicker tool changes

By pre-assembling HYDRO-GRIP and the tool in the tool-room you minimize the adjustment time at the processing machine.

Advice for tool assembly

It is vital that HYDRO-GRIP is never pressurized without being assembled with a tool on a machine spindle manufacturers.NB! Both the tool and the machine spindle must cover the length of the sleeve. To achieve optimal stabil- ity you must ensure an even contact surface throughout the entire sleeve. More detailed instructions for HYDRO- GRIP are included in the assembly instructions which are included with every product.

Temperature

Thanks to the small volume of pressurizing medium used, HYDRO-GRIP is only minimally sensitive to temperature changes. Only if the temperature varies by as much as +/- 30°C do you need to adjust the pressure of the sleeve.

Repeatability

The incredible repeatability that HYDRO-GRIP gives you, within 0.002 mm, allows you to achieve the same preci- sion even on your production machine as you achieve on your grinding station. The same repeatability is attained when using a G2, G or GE type hydraulic chuck/arbor.

Power transfer

The tables indicate the guidelines for the power in Kw (hp) that can be transferred.When using type A and AI sleeves the tool should always be bolted to the flange. The bolts suppliers have the same function as the ring nut on the B and BI type sleeves. Referring to the table to the right, using the values above we get the multiplication factor of 2.3. Multiplying the tool width, 22 by 2.3 gives us the transferable power of approximately 50 kW.
