06

Full Environmental Enclosure

Fully sealed machining cabin featuring an internal automatic chip conveyor and electrostatic oil mist separation system for a clean and safe plant environment.

Kinematic Architecture

Optimized Horizontal Layout & B-Axis Swivel

The machine adopts a horizontal structural layout consisting of the bed base, X-axis column, Y-axis ram, Z-axis ram, and B-axis rotary swivel table.

Tool Spindle Swivel (B-Axis): Swivels from -5° to +92° with backlash-elimination sector gear and hydraulic damping.
Side-Mounted Workpiece Spindle: Brings the workpiece closer to the operator door for rapid manual clamping or seamless automation integration.
Constant Temperature Spindle Cooling: High-efficiency water chiller prevents thermal expansion of bearings during prolonged grinding cycles.

Precision Machining

Micron-Level Surface Finish & Gear Accuracy

Under ambient temperatures of +5℃～+40℃ (gradient <2℃/h), the generating grinding method achieves GB/T 11365-2019 Grade 6 gear precision standards.

Surface Roughness: Ra ≤ 1.6 μm mirror tooth flank finish.
Versatile Gear Types: Spiral bevel gears, hypoid gear pairs, zerol bevel gears, and optional straight bevel gears.
Flexible Grinding Cycles: Plunge-Generating, Generating-Generating, and multi-cycle rough-to-finish operations.
