Tool-holder for woodworking ETP

Hydraulic clamping of tools gives perfect concentricity on the spindle.

ETP HYDRO-GRIP consists of two hardened steel sleeves with an intermediate layer of grease as a pressure medium. Depending on design the sleeves expand towards the spindle or towards the spindle and the tool. In this way the woodworking tool is centered. The drive from the spindle is transmitted through friction. The use of hydraulic pressurising, in conjunction with high precision in manufacturing, ensures extremely good runout and repeatability.

ETP HYDRO-GRIP solves the tool-centering problem.
With all mechanical clamping systems for woodworking tools, eccentricity between spindle and tools is rarely less than 0.04 mm. Such large eccentricity results in machining faults, poor surfaces and excessive/uneven tool wear – particularly at fast feed rates.
It becomes necessary to operate at lower feed rates than those for which machine and tools are intended. ETP HYDRO-GRIP solves the problem and at the same time boosts safety and profitability.

ETP HYDRO-GRIP increases machine feed rates
When the knives on the tool are cutting evenly the machine can be run faster without any deterioration in the surface finish.
