      DHP 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.

      Attention
      Hydraulic chuck is suitable for finishing. Rough machining will cause the short life of the chuck. And also will lead negative effects for precision and clamping.
      The operating temperature should be kept at 20~50℃ (Fig. C).
      Don't use any accessories of other brands, to avoid any negative effect.
      The sealing system is forbidden to be opened up; it might cause the leaking of the oil.
      Please maintain un-clamping condition for storage or without cutting tool.

      Frequently Asked Questions
      What is the required tool shank diameter tolerance for a DHP hydraulic chuck?
      The assembled bar size tolerance must be ≥ h6. Please refer to the h6 tolerance table for specific values based on shank diameter. Tools with flat or notched shanks must not be installed, as they can cause excessive deformation and damage to the mounting hole.
      What is the recommended locking torque for the DHP hydraulic chuck?
      The locking torque must be controlled within 6 to 9 N·m. It is strongly recommended to use a torque wrench to ensure accuracy. Torque below 6 N·m results in insufficient clamping force, while torque above 9 N·m may cause varying degrees of damage to the tool holder.
      Is the collet included with the DHP hydraulic chuck?
      No. The wrench is included with each DHP hydraulic chuck, but the collet must be ordered separately. Please select the appropriate collet model based on your specific chuck specification.
      What is the maximum RPM for the HSK-A-DHP Super Slim Hydraulic Chuck?
      The HSK-A-DHP Super Slim Hydraulic Chuck is balanced to G2.5 at 25,000 rpm, with a runout (X3D) of ≤0.003 mm. Its slim design also ensures no interference during high-speed precision machining operations.
      Can the DHP hydraulic chuck be used for rough machining?
      No. The DHP hydraulic chuck is designed for finishing operations only. Using it for rough machining will significantly shorten the service life of the chuck and negatively affect both precision and clamping performance.
      What operating temperature range is safe for the DHP hydraulic chuck?
      The operating temperature should be maintained between 20°C and 50°C (as shown in Fig. C). Do not open the sealing system under any circumstances, as this may cause oil leakage. When storing the chuck or not using a cutting tool, always keep it in the un-clamped condition.
