Summary
Compact Gang Type CNC Lathe H32I is engineered for high-precision small-part production. Its ±0.003mm positioning repeatability and Ra1.6μm surface roughness ensure consistent, tight-tolerance output for automotive, aerospace, and electronic components.
Equipped with a 3500rpm spindle, 40mm bar capacity, and linear guide rails (X:25mm/Z:30mm), this gang-type lathe supports high-volume, high-speed machining with minimal downtime. Its robust cast iron bed, treated with high-frequency quenching and aging, maintains long-term accuracy stability.
Ideal for contract manufacturers and component shops needing efficient, reliable machining of small disc or shaft parts, the H321 combines compact footprint with industrial-grade performance.
Features
- High-strength cast iron bed with high-frequency quenching and aging treatment to minimize deformation and ensure long-term structural stability
- Linear guide rails (X:25mm/Z:30mm) and precision ball screws deliver ±0.003mm positioning repeatability for tight-tolerance machining
- 3500rpm spindle with A2-5 nose type and 40mm bar capacity enables continuous high-speed production of small shaft parts
- Hydraulic chuck HC640 provides fast, secure workpiece clamping to reduce setup time and improve production efficiency
- 24m/min rapid feed rate (X/Z axes) cuts non-machining time for high-volume small-part runs
- Automatic lubrication system reduces wear on guide rails and screws, lowering maintenance costs and extending component lifespan
