3-Jaw Wedge-Type High Speed Power Chuck
Model: SH-3J-200
|
Category: Power Chucks
|
Industrial Grade
The SH-3J-200 series wedge-type power chuck is engineered for precision CNC lathe turning. Featuring an open through-hole design, it facilitates efficient bar stock feeding and high-speed machining without centrifugal clamping loss.
Key Engineering Features
- Wedge-style actuation with maximum mechanical efficiency\nLarge through-hole bore for bar machining\nInduction hardened master base jaws and guide ways\nDirect mounting to A2-6 spindle nose\nBuilt-in lubrication grease nipples on each jaw guide\nCentrifugal force compensation balance up to 5,000 RPM
Product Overview
Note: DEMO SPECIFICATIONS. Demonstrative catalogue item for engineering website presentation. Custom dimensions and factory testing parameters are available upon request.\n\nConstructed from ultra-pure chromium-molybdenum alloy steel, heat-treated and precision ground on all sliding surfaces. The innovative wedge mechanism converts axial drawbar force into uniform radial gripping force with minimal friction loss.
