Design, development, and manufacturing will be carried out through customization based on work conditions.
Applications of Precision Hydraulic Chucks: ■ Gear grinding ■ Grinding of RV reducer cycloidal gears ■ Grinding of wave gear reducers and flexible gears ■ Compressor lathe processing ■ Precision inspection ■ Processing of precision parts and thin-walled components ■ Other products requiring precise fixation Features: - Controls the expansion and contraction of the expansion sleeve by tightening and loosening screws. - The built-in independent hydraulic system allows the expansion sleeve to expand evenly both inside and outside simultaneously. - While the outer diameter automatically rises and positions itself, the inner diameter tightens onto the shaft, securely holding the outer diameter hole. - Achieves high-precision positioning and large torque transmission simultaneously.
