The following is a comprehensive introduction to the GCH-120 low-noise multi-point positioning screw
embedded module (based on the integration of technical parameters and application characteristics):
🛠️ I. Core structural design
Embedded ball screw system
Adopting preloaded C7-grade precision ball screw (optional C5-grade), the screw diameter is 16-40mm,
the lead is 5-20mm, and the ±0.01mm repeatability accuracy under multi-point positioning (≥3 points)
is achieved
The integrated alloy base has a built-in screw guide groove, which suppresses high-speed vibration and
reduces the risk of resonance through structural rigidity optimization
Low-noise operation technology
The ball circulation path noise reduction design is combined with a polymer sealing strip, and the
operating noise is ≤40dB (30% load condition), which is suitable for medical testing and laboratory
precision equipment
Motor direct connection/folding installation compatible design reduces transmission chain noise
transmission
Semi-enclosed protection
Top removable dust cover + side labyrinth seal, protection level IP40, balance heat dissipation and dust
isolation requirements
📊 **II. Key performance parameters
Features Parameters
Maximum load 120kg (horizontally installed)
Effective stroke 200–2500mm
Repeat positioning accuracy ±0.01mm (multi-point positioning)
Maximum speed 1.5m/s (long stroke requires speed reduction)
Operation noise ≤40dB (ISO standard test)
Note: When the stroke is greater than 1500mm, the speed must be limited to less than 0.8m/s to avoid
resonance-induced accuracy deviation
3. Application scenarios and advantages
Precision manufacturing: semiconductor wafer multi-point calibration platform, optical lens coating
equipment, relying on ±0.01mm level positioning stability
Medical automation: medical device assembly line, silent inspection bench, meet ≤40dB noise restriction
environment
Long stroke and heavy load: replace the traditional hydraulic positioning mechanism, support 120kg
load precision transfer within 2500mm stroke
⚠️ Fourth, Technical Considerations
Speed-stroke balance
The critical speed is negatively correlated with the screw length. When the stroke is 2500mm, the speed
needs to be controlled below 0.8m/s
Inertial load management
When the acceleration is greater than 0.3G, the handling mass needs to be reduced to avoid positioning
deviation caused by impact
This module provides a high-precision, low-vibration positioning solution for heavy-load and long-stroke
scenarios through the integration of embedded screw structure and noise reduction technology
