CNC Machining of Knurled Sleeves and Threaded Handles: Precision Turning

Manufacturing Technology & Engineering Solutions:

Manufacturing cylindrical housings, protective sleeves, and adjustment handles requires strict geometric accuracy, precise concentricity, and superior surface finishing. This series of components is manufactured using advanced CNC turning centers, combining rough turning, precision finish boring, and knurling in a single efficient machining cycle.

• DIAMOND KNURLING FORMING (DIN 82 STANDARD) Deep cross-hatched (diamond) knurling is applied to the outer diameter using plastic deformation with roller suports. This provides maximum manual grip for machine operators, preventing slipping during manual adjustments even in oily environments.
• ACCURATE STEPPED TURNING & INTERNAL BORING Precision machining of stepped shoulders on the component face and boring through-holes with tight tolerances. CNC controls guarantee ideal geometric accuracy and perfect alignment between internal and external surfaces.
• PRECISION EXTERNAL THREAD CUTTING High-accuracy metric thread cutting on the extended turned section using carbide threading inserts. Ensures clean thread flanks without burrs for smooth and reliable assembly.
• FINISHING & SERIAL QUALITY CONTROL Every single workpiece undergoes chamfering, face finishing, and burr removal. Strict dimensional inspection at every stage ensures 100% interchangeability across the entire production batch.
