As a key equipment in the field of precision machining, the CNC horizontal axis rectangular table surface grinder is widely used in high-precision machining scenarios such as molds and precision parts due to its stable grinding performance and precise control ability. A deep understanding of its grinding principle and mastery of precision control points are the core of improving machining quality.

The grinding principle of this equipment is centered around "high-speed cutting+precision feed", and material removal is achieved through the coordinated operation of the spindle system, worktable system, and grinding wheel. The spindle drives the grinding wheel on the horizontal shaft to rotate at high speed, forming the main cutting motion. The abrasive particles on the surface of the grinding wheel, with their high strength and hardness characteristics, perform small cutting and grinding on the surface of the workpiece. At the same time, the CNC system controls the torque table to drive the workpiece to complete longitudinal feed, while the grinding wheel holder achieves lateral and vertical feed. Through multi axis linkage, the grinding path is precisely controlled to achieve the preset size and roughness requirements on the workpiece surface. Compared with traditional grinding machines, the intervention of CNC systems enables digital adjustment of parameters such as feed rate and grinding speed, greatly improving the accuracy of motion trajectories.

Precision control is the core goal of CNC horizontal axis and rectangular table surface grinder machining, which needs to be systematically controlled from three aspects: equipment structure, process parameters, and operation monitoring. At the level of equipment structure, the rotational accuracy of the spindle directly determines the grinding reference accuracy. By using dynamic and static pressure bearings or high-precision rolling bearings, the radial and axial runout of the spindle can be effectively suppressed; The straightness error of the platform guide rail will be directly transmitted to the workpiece. By using plastic coated guide rails or rolling guide rails combined with pre tightening technology, the motion error can be significantly reduced.

Optimization of process parameters is a key step in precision control. The grinding speed should be reasonably matched according to the material of the workpiece and the characteristics of the grinding wheel. If it is too high, it can easily lead to increased wear of the grinding wheel, while if it is too low, it will affect the processing efficiency and surface quality; The setting of feed rate should follow the principle of "efficient rough grinding and precise fine grinding". Using a small feed rate in the fine grinding stage can reduce machining stress and improve surface accuracy. In addition, the quality of grinding wheel dressing is crucial. Regularly using a diamond pen to dress the contour of the grinding wheel can ensure the consistency of the abrasive cutting edge and avoid surface quality degradation caused by grinding wheel passivation.

Real time monitoring during operation is also essential. Real time feedback on the motion position of each axis and closed-loop correction through the built-in position detection module of the CNC system; To address the vibration issues during the grinding process, shock-absorbing bases or dynamic balancing devices can be used to suppress interference. The precise control of multiple stages jointly ensures the high-precision machining capability of the CNC horizontal axis and rectangular table surface grinder, providing reliable support for precision manufacturing.
