MICRO-T400
Ultra-precision CNC turning machine with spindle runout ≤0.2μm for delivering ≤0.5μm roundness and Ra≤0.02μm surface finish
The MICRO-T400 high precision CNC lathe is built as a single-spindle mineral-cast slant-bed structure with a compact layout. It integrates static-pressure built-in spindle technology, hydrostatic guideways, a hydrostatic tailstock and high-precision drive systems (ultra-precision ball screws or linear motors), supported by vibration- and deformation-resistant bed construction. The ultra-precision CNC turning machines hardened materials from 58-68 HRC and serves applications in aerospace, optics, bearings, ball screws, hydraulics, automotive and precision mould manufacturing.
Features
- Uses a high-precision imported Italian servo turret with faster tool indexing. Turret positioning is achieved by a high-accuracy face-gear coupling with hydraulic clamping, ensuring high positioning accuracy, zero backlash, no wear and low noise.
- The hydrostatic spindle provides ＜0.2 μm runout and high static stiffness, far exceeding the accuracy of conventional rolling-bearing spindles. The MICRO-T400 achieves roundness ≤0.5 μm and surface roughness Ra ≤0.02 μm, enabling hard turning, precision turning and “turn-instead-of-grind” capability.
