China Surface Grinding Machine Manufacture and Factory

Surface Grinding Machine

Saddle Type-PCA Series

The PCA&PCD series uses high-grade cast iron components that have undergone annealing and vibration aging treatments to enhance stability. The thick material body meets the demands of heavy cutting and precision grinding, while wear-resistant rubber guide rails are hand-scraped for accuracy. The high-precision spindle is equipped with P4-grade bearings and a surface finish of Ra0.4, enhanced by larger bearings to improve performance.

Utilize high-precision C3 grade ball screws with dual nuts to ensure ease of operation, high accuracy, and durability. Low-noise motors provide minimal vibration and reliable performance, while the hydraulic system features low vibration and damping functions. These characteristics collectively ensure smooth and reliable operation of the equipment.

The innovative lubrication circuit has a 95% recovery efficiency, reducing coolant contamination. Automatic self-inspection at startup and fault alarms ensure thorough lubrication of the guides. This intelligent maintenance system extends the lifespan of the equipment and reduces maintenance costs.

Machine Model

AHR	Hydraulic Left/Right, Stepper Front/Back, Up/Down with Rapid Lift	The left/right movement is controlled hydraulically, the front/back movement is controlled by stepper motors, and the up/down movement includes a rapid lift function for faster operation.
AHD	Hydraulic Left/Right, Stepper Front/Back, Servo-Controlled Up/Down	The left/right movement is controlled hydraulically, the front/back movement is controlled by stepper motors, and the up/down movement is automatically controlled by servo motors for precision.
NC	Hydraulic Left/Right, Servo-Controlled Front/Back, Servo-Controlled Up/Down	The left/right movement is controlled hydraulically, while both the front/back and up/down movements are automatically controlled by servo motors for higher precision and automation.
CNC	CNC (X, Y, Z Axes Numerical Control)	All three axes (X, Y, and Z) are controlled numerically using a CNC system, providing full automation and high precision for complex machining tasks.
