HYM255 Vertical Spindle CNC Double-Sided Grinding Machine

Horizontal Spindle Double-Sided Grinding Machines are designed for precision grinding of various shaped, non-circular, and circular thin metal and non-metallic parts, simultaneously achieving precise grinding on both top and bottom parallel ends. Ideal for high-efficiency processing of large-volume workpieces. Used for double-sided grinding of products such as hydraulic and pneumatic components, hydraulic motor parts, automotive steering pump components, refrigeration compressor parts, oil pump and nozzle parts, engine parts, high-precision bearings, seals, piston rings, measuring tools, molds, instruments, hard alloy blades, ceramic valve cores, magnetic materials, etc.

Machine Tool Structural Features:

1. The machine tool features a vertical box structure with cast iron bed and worktable, which have been时效 treated for excellent overall vibration resistance. It reduces vibration and deformation during machining, ensuring rigidity and precision of the machine tool, thus guaranteeing machining accuracy.

2. The upper and lower grinding heads are vertically aligned on the same centerline, featuring a rigid, shaft-type configuration for reliable thermal stability. The grinding head's infeed and retract guides utilize linear rigid guides, offering excellent rigidity and vibration reduction with high positioning accuracy. The feeding mechanisms of both the upper and lower grinding heads are equipped with servo control systems, ensuring a minimal infeed value of 0.001mm for the abrasive wheel, allowing for wheel consumption compensation and dressing compensation.

3. The main shaft is driven by AC variable-frequency stepless speed, accommodating various grinding process requirements. It features high-precision bearings for excellent rotational accuracy and precision retention. The grinding head feed utilizes precise ball screw, ensuring high accuracy and stability.

4. The workpiece feeding mechanism utilizes a turntable or through-type feeding, featuring variable speed control for feeding speed. It can be equipped with material feeding and discharging machines for automated production line grinding. The feeding mechanism and column are designed with a hinge structure for easy wheel change.
