MK1320 CNC cylindrical grinder semi protection

The structure and characteristics of machine tool

MK1320 CNC cylindrical grinder processing equipment used in large quantities of shaft parts with cylindrical grinding. In one clamping workpiece case, automatic cycle to complete multi gear outer circle grinding. Grinding is suitable for car, motor,gear box and so on shaft parts.

- bed is an integral type T shaped structure, the internal ribs is box type layout, and the use of high strength cast iron casting, the high overall stiffness. To meet therequirements of basic parts of high efficiency, high precision equipment, the design of the cooling water flume to ensure smooth. The bed bottom surface is provided with three to five supporting surface, used for installation and horizontal adjustment of machine tool.

- adopt the domestic numerical control system (KND or GSK) to achieve X, Z axis and two axis linkage.

- longitudinal feed use of precision ball screw pair, the supporting bearings adopt high precision ball screw special bearings, to ensure that the most suitable axial and radial clearance and precision.

- grinding wheel spindle system using high precision three tile dynamic pressurespindle bearing components, has the advantages of high precision, strong rigidity characteristics etc.. The wheel shaft to rotate by the low vibration motor drive.

- spindle adopts precision sliding cone bearings and precision paired ball bearing assembly structure. Frame front side of the fixed grinding wheel corrector, make programming can realize automatic compensation.

Independent cooling water tank - magnetic separation with high efficiency grinding,fully meet the production need for continuity, ensure the grinding quality.

- semi closed machine shield shell, preventing water leakage, improve machineoperation safety and environmental protection.
