CNC Cylindrical Grinder


The CNC cylindrical grinding machine is pre-programmed according to the processing requirements, and the control system sends out numerical information instructions for machining, mainly for grinding cylindrical and conical outer surfaces.

CNC Cylindrical Grinder

CNC cylindrical grinding machines generally have the characteristics of generalization, high degree of modularity, high precision, high rigidity, high efficiency and high adaptability.

According to the different types of CNC cylindrical grinding machines, it is suitable for batch processing of related parts of automobiles, motorcycles, air compressors, bearings, military, aviation, aerospace etc.

Main features

CNC cylindrical grinding machine is composed of bed, work table, grinding wheel frame, head frame and tailstock.

  1. Bed and workbench

The bed is made of large round holes and shark fin-shaped ribs. After long-term use, the machine has good dynamic stiffness and static stiffness.

The work surface can be used to grind the conical surface on the upper and lower surfaces.

The guide rail of the bed and the worktable adopts a plastic guide rail, and the friction coefficient is small.

The table is directly driven by the servo motor to move the ball screw, and the movement is stable and reliable.

  1. Grinding wheel frame

The linear speed of the grinding wheel is less than 35m/s, and the grinding efficiency is high. The grinding head bearing is a three-grid dynamic bearing with a large wrap angle, and the rotation precision is high.

The grinding wheel frame movement (X direction) is directly dragged by the servo motor and the ball screw with a minimum resolution of 0.0005 mm.

  1. Head frame

The rotation of the headstock dial is driven by the motor frequency conversion speed control, the dial is rotated, and the dial rotation speed is 40-500r/min stepless speed change to adapt to the grinding of workpieces of different diameters, different materials and different requirements.

  1. CNC box and electric cabinet

There is an independent CNC operation box with LCD display, machine operation button, 1um band compensation switch, manual pulse generator and so on.

  1. End gauge and radial gauge

When the numerical control cylindrical grinding machine has a radial measuring instrument, the measured value is automatically input into the numerical control system, and the numerical control system sends a signal to rotate the X-direction servo motor to drive the ball screw to a given position, so that the size of the grinding workpiece can be stably achieved. position. The dispersion degree of grinding size of batch workpiece is less than 0.003mm.

Performance structure

Mechatronics structure layout, using work area protection or overall protection, easy maintenance, in line with ergonomic requirements.

The grinding wheel spindle has high rotation precision and strong rigidity. The linear speed of the grinding wheel can reach 60m/s; the linear speed of the CBN grinding wheel can reach 80m/s.

The two-axis linkage feed, the work table and the grinding wheel frame are driven by the AC servo-ball screw pair.

A variety of diamond dressing devices are available to achieve precise CNC dressing and automatic compensation.

The active measuring device is configured to achieve full closed loop control of the grinding process.

The numerical control system has all-round control functions such as grinding process program change, workpiece quality management, machine condition monitoring, fault self-diagnosis and abnormal alarm. The menu interface is easy to input.
