ERI America introduces hydraulic chucks from WTE Präzisionstechnik GmbH. The high-performance holders represent an advanced part of the company's hydraulic chuck program.
Extreme temperature stability, super strong holding forces combined with excellent vibration damping and high radial stiffness reportedly improve surface qualities on the workpiece. Other outstanding characteristics are the solid construction, the sealed clamping system (maintenance free) and the positive cost savings because of reduced cutting times.
WTE hydraulic chucks offer high radial accuracy and excellent vibration damping. They reduce microstructure cracking on the tool's cutting edge and increase productivity, according to the company. WTE manufactures standard hydraulic chucks with axial and radial adjustment in the most common shank forms. Utilizing the company's reducing sleeves or its hydraulic chuck extensions makes this clamping tool flexible as well.
New micro universal chucks were developed specifically for high speed micro machining up to 60,000 rpm while delivering concentricity less than 0.005mm. Chucks offer a clamping range from 0.2 to 6.4mm with precision and reliability. They are an excellent choice for medical manufacturing, electronic device manufacturing and moldmaking.
Related Glossary Terms
- chuck
chuck
Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
- microstructure
microstructure
Structure of a metal as revealed by microscopic examination of the etched surface of a polished specimen.
- shank
shank
Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.
- stiffness
stiffness
1. Ability of a material or part to resist elastic deflection. 2. The rate of stress with respect to strain; the greater the stress required to produce a given strain, the stiffer the material is said to be. See dynamic stiffness; static stiffness.
