CNC Honing Service Process

The core principle of CNC honing technology lies in the combination of its advanced computer control system and precise mechanical structure, which achieves high-precision processing of the workpiece surface by precisely controlling the movement trajectory and parameters of the honing tool. This technology combines the essence of modern CNC technology and the traditional honing process, which brings a revolutionary change to industrial production.

In the CNC honing equipment, high-precision CNC system is its ‘brain’, responsible for according to the preset procedures, precise control of the honing head rotation, feed speed, processing depth and other key parameters. At the same time, advanced sensors and feedback systems act as ‘eyes’ and ‘ears’, they can real-time monitoring of a variety of data in the machining process, such as machining temperature, cutting force, vibration, etc., to ensure machining accuracy and stability.

In terms of workflow, CNC honing service starts from workpiece preparation, which includes workpiece cleaning, positioning and fixing steps to ensure that the workpiece maintains a stable posture during the machining process. Subsequently, appropriate honing tools and machining parameters are selected according to the material, shape and machining requirements of the workpiece. The setting of these parameters is crucial, and they will directly affect the machining accuracy and efficiency.

During the machining process, the CNC system controls the motion of the honing head according to the preset program. The honing head rotates at high speed while carrying out feed movement along the preset trajectory to carry out precision machining on the surface of the workpiece. The sensor monitors the processing status in real time, and once an abnormality is found, it immediately feeds back to the CNC system, which will automatically adjust the processing parameters or take other measures to ensure the stability and precision of the processing.

CNC honing service usually includes two stages: rough honing and fine honing. Rough honing is used to remove most of the residue on the surface of the workpiece, laying the foundation for subsequent fine honing. Fine honing is used to finely machine the surface of the workpiece to achieve the required machining accuracy and surface quality. These two stages can be flexibly adjusted and optimized according to specific needs.

After machining, the workpiece needs to undergo quality inspection and subsequent processing. Quality inspection includes dimensional measurements, surface roughness testing, etc. to ensure that the machining quality meets the customer's requirements. Subsequent processing may include cleaning, rust prevention, packaging and other steps in order to deliver the workpiece to the customer.
