What is Trapezoidal Screw
T-screws: the “skeleton” of automation equipment
- Usage: Linear actuators that drive automated production lines, material handling robots, palletizing robots, and other equipment to achieve precise positioning, sorting, and assembly.
- Material/geometric features: commonly used stainless steel, alloy steel; The structure includes complex raceways and spiral angles ± 12°; The size range is 15-75mm OD, and the longest machining stroke is 3600mm.
- Common risks: Traditional processes are prone to deformation (deflection ≥ 0.03mm), surface burns (defect rate 12%), poor chip evacuation (15% increase in downtime); Traditional milling cannot meet the needs of high-precision raceway machining.
Trapezoidal Screw Whirling Core Pain Point
Three major processing bottlenecks hinder the mass production of automation equipment
- Pain point 1: Insufficient accuracy
- Efficiency: 20% increase in rework time
- Cost: 500 yuan more rework fee per batch
- Quality: Defect rate up to 15%
- Pain point 2: Spiral angle adjustment is time-consuming
- Efficiency: 30% longer changeover intervals
- Cost: Labor cost increases by 30 yuan/piece
- Quality: Angular error leads to 10% assembly failure rate
- Pain point 3: Poor chip evacuation
- Efficiency: 15% increase in downtime cleanup time
- Cost: 25% increase in tool loss
- Quality: 12% surface burn rate
Trapezoidal Screw Whirling Process
PH80-4000 core link: cyclone milling
Complete link: blank preparation→ roughing→ cyclone milling (PH80-4000 core link), →surface treatment→ quality inspection
- Core Position: Cyclone milling is responsible for raceway forming and is a critical step in determining the screw’s accuracy
- Connection relationship: After rough machining, it directly enters cyclone milling, and realizes the precise machining of raceways and spiral angles through 4-axis linkage; Automatic chip evacuation ensures that subsequent surface treatment is free of impurities
