derekDHP Hydraulic Chuck Manuals

1: Please completely clean any dust, oil or other dirt within the mounting hole before installing the tool into the hydraulic tool shank. These factors will have a negative impact on the clamping force and may even cause the tool to slip during machining.

2: Confirm that the diameter tolerance of the tool shank to be installed is within h6 (refer to the h6 tolerance table). Do not install tools with flat or notched shanks (refer to Fig. B), and empty locking is forbidden too. These will all lead to excessive deformation and damage of the mounting hole.

3: Please insert a cutting tool completely close to the bottom of the inner bore of the chuck. There is an adjustable support screw at the bottom of the hole (see Fig. A ③), and the maximum upward adjustment of the support screw is 8mm.

4: Operate the T-shaped wrench (see Figure A①) to adjust the locking screw (see Figure A②). The locking torque must be controlled within the range of 6 to 9 Nm (it is recommended to use a torque wrench to ensure this). If it is lower than 6 Nm, the clamping force of the tool holder will be insufficient, and if it is higher than 9 Nm, the tool holder will be damaged to varying degrees. For the clamping torque of each type of tool holder, please refer to the reference table in detail.

derekAttention

1: Hydraulic chuck is suitable for finshing. Rough maching will cause the short life of the chuck. And also will lead netive effects for precision and calmping.

2: The operating temperature should be keeping at 20~50℃ ( Fig.C ).

3: Don't use any accsories of other brand, to avoid any negtive effect.

4: The sealing system is fobidden to be opened up, it might cause the leaking of the oil.

5: Please maintain un-clamping condition for storage or without cutting tool.
