The PK36B series CNC follow-up tailstock is a supporting accessory for CNC rotary worktable. When working, using the control system of the host or a specialized control system to control the turntable can achieve both the function of a regular tailstock and synchronous rotation and braking with the workbench. Using the large aperture through-hole in the spindle, install pneumatic (hydraulic) spring clamps, power chucks or tips to assist in clamping the workpiece clamped on the turntable, achieving the machining of evenly divided and unevenly divided continuous holes, grooves and curved surfaces with high precision.
