1. INSIGHT STAR SR20 Lathe Collet And Guide Bush

The collet is a critical component of STAR Swiss-type lathes (precision sliding-headstock lathes), enabling high-accuracy, 

high-efficiency machining of complex small parts. 

Below is a detailed breakdown of its functions, key benefits, and industrial applications.  

STAR SR20 Collet Functions

1. High-Precision Clamping 

   - Made from high-rigidity materials (alloy steel/ceramic) with precision grinding, ensuring repeatability within ±0.005mm.  

   - Stable gripping of ultra-thin bar stock (Ø0.5–32mm) with minimal runout.  

2. Multi-Tasking Synchronization

   - Works with multi-spindle and multi-turret systems for simultaneous machining (e.g., main collet turning while sub-spindle finishes the backside).  

3. Rapid Material Change 

   - Hydraulic/pneumatic actuation enables 1–2 sec bar feed changes, boosting productivity.  

4. Anti-Collision Design  

   - Compact structure avoids interference with rotating tools or guide bushings, ideal for complex contours (threads, eccentric holes).

STAR SR20 Collet Chuck Advantages

1.Reduced Cycle Time

   - Sub-spindle (counter collet) grips the workpiece for complete machining in one setup, eliminating secondary operations.  

2. Complex Parts in Single Pass

   - With guide bushing support, processes slender parts (L/D ratio >20:1) like medical guidewires without repositioning.  

3. Wide Material Compatibility 

   - Options: spring collets (standard), hydraulic collets (high grip force), heat-shrink collets (for hard materials like Inconel).

1. Medical Devices  

   - Bone screws, endoscope components – surface finish Ra ≤0.4µm with vibration-free clamping.  

2. Automotive Electronics  

   - Fuel injector nozzles, sensor housings – high-volume production with unattended operation.  

3. Aerospace 

   - Turbine blade tenons, fuel valve parts – withstands high-temperature alloys (e.g., Ti-6Al-4V).  

4. Watchmaking  

   - Gear shafts, balance staffs – sub-micron tolerances for luxury timepieces.
