How does the dual-wheel head design of the Double Wheelhead CNC Cylindrical Grinding Machine achieve simultaneous processing of rough grinding and fine grinding?

The Double Wheelhead CNC Cylindrical Grinding Machine achieves simultaneous processing of rough grinding and fine grinding through a unique dual-wheel collaborative design. The core of this design concept is to let the two grinding wheel heads take on different processing tasks respectively, and complete the entire process from rough processing to fine processing through precise cooperation. The rough grinding wheel is mainly responsible for quickly removing most of the processing allowance, while the fine grinding wheel focuses on obtaining the final required dimensional accuracy and surface quality. The two grinding wheel heads work together under the unified scheduling of the CNC system, so that the workpiece can complete all grinding processes in one clamping.

The rough grinding wheel will use abrasive types and grain sizes that are more suitable for efficient material removal. The design focus of this grinding wheel is to maintain a high material removal rate while ensuring sufficient durability. The fine grinding wheel will choose finer abrasives, and its structural design focuses more on obtaining excellent surface processing quality. The two grinding wheels also have obvious differences in the processing parameter settings. Rough grinding uses a larger cutting amount, while fine grinding uses more refined processing parameters. These differentiated settings are all to give full play to the best performance of each grinding wheel.

The CNC system plays a key role in the entire processing process. The advanced multi-axis linkage control system can independently and accurately control the motion trajectory and processing parameters of the two grinding wheel heads. The system's built-in process database stores the optimized parameter combinations for different materials and different processing requirements. The operator only needs to call the corresponding processing program. This intelligent control method not only ensures processing accuracy, but also greatly simplifies the operation process.

The common opposed layout arranges the two grinding wheel heads on both sides of the workpiece. This design is particularly suitable for the processing of long shaft parts. Under the opposed layout, the two grinding wheels can process the workpiece at the same time, significantly improving production efficiency. For shorter parts, a parallel layout can be used to allow the two grinding wheels to process the workpiece in sequence along the same direction. Different layout methods are all designed to better adapt to the processing needs of specific types of parts.

In order to ensure processing accuracy, the machine tool is equipped with a complete real-time compensation system. This system can continuously monitor the processing status of the workpiece and dynamically adjust the processing parameters according to the actual situation. The automatic compensation function of the grinding wheel wear can timely correct the dimensional deviation caused by the grinding wheel loss to ensure the stability of the processing accuracy. The introduction of the online measurement device further improves the reliability of the processing process and better guarantees the product quality.

In the actual processing process, taking a typical engine crankshaft as an example, the advantages of the double grinding wheel head can be clearly seen. The rough grinding wheel first quickly removes most of the processing allowance to prepare for subsequent fine processing. Then the fine grinding wheel immediately performs fine processing to obtain the final required dimensional accuracy and surface quality. The entire processing process is completed in one go, which is not only efficient, but also avoids the errors that may be caused by multiple clamping because all processes are completed in one clamping.

Compared with traditional single-wheel grinders, the processing time can be shortened by nearly half, which is of great significance for mass production. At the same time, due to the continuous rough grinding and fine grinding, the processing accuracy of the workpiece is also better guaranteed. Especially for some parts that are easy to deform, this processing method can effectively reduce the deformation problem caused by multiple clamping or process intervals.

Double wheel head CNC cylindrical grinding machine is particularly suitable for processing large quantities of high-precision parts. It is widely used in bearings, hydraulic components, automotive parts and other fields. For some difficult-to-process materials, this machine tool can better play its unique advantages. Through the reasonable combination of rough and fine grinding, it can not only ensure processing efficiency, but also obtain ideal surface quality.
