The CNC Vertical Grinder is a high-precision grinding machine designed for the manufacturing industries such as equipment, bearings, military, energy, and aerospace. It is ideal for processing components with high surface quality and precision, including disc-shaped, ring-shaped, and sleeve-shaped parts. The machine efficiently processes the inner hole, outer circle, end face, groove, and taper surface in a single clamping.
High Precision: Achieves a machining accuracy of IT3 to IT2, with a surface roughness of ≤ Ra0.2.
Dual Grinding Heads: Equipped with a left and right double grinding head configuration, allowing simultaneous grinding of multiple workpiece surfaces, improving grinding efficiency.
Multi-Surface Grinding in One Clamping: Capable of processing the workpiece's bore, external diameter, end face, taper, and bearing groove in one setup.
Enhanced Functionality: Features optional functions like in-process measurement, dynamic balancing, AE anti-collision system, and automatic wheel magazine to optimize machining quality, efficiency, and safety.
High-power And High-precision Electric Spindle
1. High precision: grinding spindle runout ≤1μm, spindle vibration ≤0.15mm/s.
2. High configuration: synchronous direct-drive motor + online dynamic balancing.
3. High speed: high linear speed + high rigidity performance.
