The length of the CNC chuck tie rods to determine: you need to bar the rotary cylinder piston and the chuck of the middle kernel (wedge tie rod) also pushed to the chuck are pushed to the forefront, and then a ruler to measure out from the chuck to the tail of the cylinder, including the total length of the threads, i.e., length of the CNC chuck tie rods.
The CNC chuck uses a modular design method. The machine tool according to user requirements, using a variety of domestic and foreign CNC systems, screen LCD CRT display, to achieve the Chinese character prompts full-screen editing.
The main spindle is supported by high-precision rolling bearings; the main drive adopts imported frequency converter speed controller to realize stepless speed regulation function and constant line speed cutting function; the bed adopts super audio hardening treatment, and adopts plasticized guide rails; the X-axis and Z-axis adopt stepping or servo motors, and the feed movement is realized through ball screws.
Expanded Information:
1 、According to the stroke needs to choose the cylinder.
2, according to the tensioning force needs to select the cylinder.
3, according to the connection mode need to select the cylinder.
These three points should be considered.
Generally hydraulic chuck is through the threaded joint to connect with the rotary hydraulic cylinder rod.
Chuck disassembly, the first generally 6 screws (connected to the spindle nose) to remove, and then let the chuck out of the nose, small chuck can be hand-held, counterclockwise rotation of the chuck, will be unloaded from the tie rod (the chuck must be held, be careful to fall, in addition to unloading the process of keeping the chuck is always in the center, don't let the tie rod threads are injured).
