Swiss-Type Lathe Hydraulic Chuck: The “Invisible Finger” in the Long-Shaft Cabin — JSWAY CNC COMPANY

I. Role in a nutshell
Inside the Swiss-type lathe spindle cabin, the bar stock runs through and the guide bush locates. The hydraulic chuck acts as an “invisible finger” — axial hydraulic pressure is converted into radial clamping force, allowing instant clamping and unclamping of the bar, while withstanding all cutting reaction forces from turning and milling.

II. Structure family (JSWAY field version)

III. On-site identification at a glance**
• Listen: clamping “click”, unclamping “hiss”, no hydraulic impact noise.
• Watch: jaws move radially in sync, bar surface no indentation or scratch.
• Touch temperature: after continuous clamping, chuck housing only slightly warmer than body temperature, no hot hand phenomenon.

IV. Maintenance “two-step method”

V. Selection & Matching**
• Small diameter long shaft: choose rear-pull hollow chuck, through without obstruction.
• Large diameter heavy cutting: choose wedge-lever composite type, clamping force self-compensation.
• Medical/food grade: optional stainless steel jaws + fully enclosed shield, no rust contamination.

VI. JSWAY Service**
• Factory-calibrated clamping force curve, scan code to check clamping force-displacement graph.
• Provide on-site clamping force re-calibration service to restore factory accuracy.
• Common jaws shipped within hours, reducing customer downtime waiting.

One-sentence summary**
Treat the hydraulic chuck as the “invisible finger” of the Swiss-type lathe — choose the right structure, adjust clamping accurately, maintain diligently — so that every bar clamping is “synchronous, mark-free, constant temperature” — this is another layer of quality insurance JSWAY provides for your long-shaft machining.
