Description:
The SG2550AHD is a high-performance 3-axis automatic precision
surface grinder designed for ultra-precise surface and face
grinding of small-to-medium sized parts. It is widely used in mold
& die manufacturing, automotive component production, electronics
assembly, and general precision machinery industries.
Equipped with PLC and servo motor control, the machine features
plastic-coated counter guides on the X and Y axes to minimize
stick-slip effects, ensuring smooth and stable movement. The
spindle utilizes clearance-free, pre-tensioned bearings for
exceptional accuracy, while the robust structure guarantees
rigidity even under heavy work loads. The state-of-the-art
hydraulic system delivers soft, vibration-free table traverse, and
automatic vertical feed with servo motor allows for precise control
over finishing and spark-out operations.
