KZJ type inner expansion chuck is featured by back pull action. After being fitted with the baffle plate and accurately positioned in axial positioning. After being pulled back, the collet chuck fully fits the chuck and relies on the stop device, forming stable and firm clamping force. The clamping force efficiency is generally the same even when short workpiece is clamped.
The cone of piecewise chuck completely fits with the chuck, forming a combined solid fixture. The processing rigidity, mechanical stability and clamping accuracy are therefore greatly improved.
The machine can be used in combination with CNC lathes, special machines, or other rotary turning machinery for turning, grinding, milling etc.
High concentricity and repeatability within 0.01mm. Air tightness detection device can be added. Suitable for blind hole clamping.
Pull-Back Mechanism
Ensures a tight grip by pulling back the workpiece against the chuck base, reducing movement and increasing stability.
Inner Expansion Design
The rubber expansion system provides a secure hold inside blind holes, accommodating various workpiece diameters.
Blind Hole Compatibility
Optimized for blind hole machining applications, ensuring effective clamping in challenging setups.
High Durability
Made with robust materials to withstand intensive use in demanding industrial environments.
Easy to Use
Simple setup and operation minimize downtime and enhance productivity.
CNC Machining: Stable and precise clamping for blind hole workpieces during high-speed operations.
Aerospace Manufacturing: Ideal for machining lightweight, complex components with tight tolerances.
Automotive Industry: Ensures accurate clamping for engine components and other critical parts.
Electronics Production: Suitable for handling small, delicate components in blind hole configurations.
General Metalworking: Effective for machining, drilling, and finishing blind hole workpieces.
