Characteristics and Grinding Angle Explanation of Centerless Grinding machines

Mainly used for precision grinding of end faces, outer circles, and conical surfaces of batch shaft parts, it is the main equipment in industries such as automotive engines. Centerless Grinding machines are also suitable for processing shaft parts with small batch sizes and high precision requirements in military, aerospace, and general precision machining workshops. The automatic grinding cycle of the machine tool is controlled by a CNC system.

Centerless Grinding machines is one of the most commonly used grinding machines in the market today, recognized by users for its easy operation and high cost-effectiveness. However, problems such as low grinding efficiency and unstable dimensions often arise when processing high-quality parts. Manual grinders often require operators to stop and manually measure whether the grinding has reached the size during the grinding process, which is inefficient. To solve the above problems, both PLC and CNC controlled centerless grinders have emerged, and their excellent performance and high efficiency are changing the habits of users operating cylindrical grinders. The centerless grinder achieves centralized data management and improves maintainability by integrating the HMI of various control components. PLC、 The measuring device can monitor and set parameters on the same operation screen. Due to the use of a touch screen, functions and data can be selected and inputted through the touch screen during daily operations. It is also possible to operate various buttons on the screen, reducing the number of buttons on the operation panel and improving operability. The centerless grinder can be used to grind 7:24 large cone angle inner and outer circular parts, as well as shaft, sleeve, ring plug gauge and other parts that require high precision and smoothness. The centerless grinder is suitable for single piece or small batch processing of the above precision parts. The centerless grinder can move longitudinally, and the grinding wheel holder can quickly advance and retreat.

Characteristics of Centerless Grinding machines: A. One person can operate 2-3 centerless grinding machines simultaneously; B、 Low operating costs; C、 Improve the utilization rate of workshop area; D、 Centerless Grinding machines improves production efficiency and yield, with absolute control over processing rate values; Structural features of the centerless grinder: a. The worktable of the machine tool moves longitudinally, and the rapid advance and retreat of the grinding wheel frame are controlled by hydraulic pressure. The workpiece rotation is driven by a DC motor, which can be infinitely variable in speed range. b. The lubrication oil pump, cooling pump, and grinding wheel frame of the grinding wheel frame spindle bearing are all driven by separate electric motors.

Grinding angle of centerless grinder:

Diameter grinding: When producing in small quantities, automatic feeding combined with a spark free timer can achieve good grinding quality for centerless grinding machines. When producing in large quantities, the two-stage automatic feed and two-stage measuring device (special attachment) can provide the best output and grinding effect for the centerless grinder (NC/CNC models).

Slope grinding: The workpiece can be supported by a chuck or two centers, and both the centerless grinder and the grinding wheel head can rotate and be easily adjusted.

Inner diameter grinding: The inner diameter grinding accessory (special accessory) of the centerless grinder can grind the inner diameter by simply pulling down the inner diameter grinding spindle and fixing it in the grinding position.

Horizontal Grinding: The automatic intermittent feed and hydraulic driven worktable enable the most effective horizontal grinding of the workpiece

End face grinding: Remove the rotating cover of the working spindle head, replace it with a three jaw or four jaw chuck to change the position of the positioning tip, and rotate the chuck. Fix the centerless grinder at a 90 ° position to perform end face grinding and shoulder grinding: When the outer diameter of the workpiece and its shoulder need to be ground at once, the workpiece is supported by two centerpieces. Modify the grinding wheel to the right of the grinding wheel head and rotate it by one angle to grind.
