What is Worm
Purpose: The core component of the automobile sunroof drive system, to achieve deceleration and torque increase, and to accurately control the opening and closing of the sunroof;
Material/geometric features: high-quality alloy steel (40Cr/20CrMnTi), HRC60±2 after heat treatment, helix angle about 6°, compact structure;
Common risks: low efficiency of traditional vertical machining centers (15min per stick), poor roughness (Ra1.6+), easy deformation/cracking of hard material processing.
High Precision Whirling Core Pain Point
Pain point 1: The traditional process is inefficient
- Efficiency: 50% longer production cycle and 10% order delay rate
- Cost: Labor + rework cost increases by 20 yuan/root
- Quality: 15% scrap rate
Pain point 2: The roughness of hard material processing is not up to standard
- Efficiency: Secondary sanding increases by 10 minutes/root
- Cost: Polishing consumables + labor cost 15 yuan/piece
- Quality: Customer complaint rate 20%
Pain point 3: High labor costs
- Efficiency: Only 200 pieces per shift
- Cost: 3 people operate 5 equipment, monthly labor cost of 30,000 yuan
- Quality: Human error leads to a scrap rate of 8%
High Precision Whirling Process
Links: blank preparation→ roughing→ MX500-N50 cyclone milling finishing→ surface treatment→ quality inspection
At the heart of the matter: The MX500-N50 replaces traditional milling and is a key part of accuracy and efficiency
Connection: After finishing, it goes directly into the surface treatment, without the need for secondary processing
- Method: Material selection→ heat treatment (850°C±10°C isothermal quenching) → rough car shape
- Parameters: Heat treatment hardness HRC60±2
- Risk control: Isothermal quenching avoids deformation
- Equipment: Heat treatment furnace
MX500-N50 finishing - Method: Hydraulic chuck clamping → cyclone milling head for high-speed cutting
- Parameters: cyclone milling speed 3000-4000rpm, feed 0.05mm/r, cutting depth 0.1mm
- Risk Control: High-pressure cooling systems prevent burns
- Equipment: MX500-N50 precision cyclone milling
Surface treatment - Method: Ultrasonic cleaning → anti-rust treatment
- Parameters: Cleaning solution concentration 5%
- Risk control: 30 micron filtration avoids residue
- Equipment: Ultrasonic cleaning machine
Quality inspection - Method: The roughness meter detects the Ra value → the spiral angle is measured in three coordinates
- Parameters: Detection accuracy± 0.01mm
- Risk control: 100% full inspection
- Equipment: roughness meter, coordinate measuring machine
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.
