What is Worm
- Usage: Precision transmission components (worms, planetary screws) for automotive drivetrains, consumer electronics (smart watches), smart homes (door locks), medical devices (infusion pumps).
- Material: HRC58-62 alloy steel, stainless steel, and other hard materials.
- Geometric features: small modulus (0.2-1.5mm), helical elevation angle 0-30°, high tooth profile accuracy requirements (±0.005mm).
- Common risks: machining deformation, surface scratches, thread tooth shape errors, hard material chipping.
High Precision Whirling Core Pain Point
There are three major pain points in traditional vertical machining center processing:
- Low efficiency: It takes 15 minutes to process a single worm, which cannot meet the bulk order;
- Poor accuracy: surface roughness Ra≥1.2μm, scrap rate up to 8%;
- High cost: one person, one machine mode, labor cost accounts for 35%, and hard material processing tools wear quickly.
High Precision Whirling Process
Blank (Forgings/Castings) → Roughing (Removal of Allowances) → MX500-N50 Cyclone Milling Finishing (Thread Forming) → Surface Treatment (Deburring) → Inspection (Dimension + Roughness)
Key points of the sub-link
- Rough machining: use ordinary milling machine to remove 70% allowance and control deformation (residual stress ≤50MPa);
- Cyclone Milling Finishing:
- Equipment: MX500-N50 cyclone milling, C-axis direct drive motor + grating full closed-loop control;
- Parameters: cyclone milling head speed 2000-5000r/min, screw lift angle 0-30°, feed speed 8m/min;
- Risk control: The online measurement system monitors dimensional errors in real time, and the compensation amount ≤ 0.002mm;
MX500-N50 External Screw Whirling Machine
MX500-N50 precision cyclone milling is a special machining machine tool for small modulus precision worm, planetary screw, trapezoidal thread and other parts. Adopting full closed-loop control technology, it can process HRC60±2 degree hard materials, with a surface roughness of Ra 0.3μm or less, and the pitch accuracy meets the JIS B1192-C5/GB/T17587.3-P5 standard. The equipment has strong stability, simple operation, and supports the production mode of one person and multiple machines, effectively reducing labor costs and production cycles.
