YHDM580D high-precision vertical double-end grinder

Nowadays, many factories are looking for processing equipment that can not only ensure accuracy but also improve efficiency. Especially in the field of surface grinding, how to achieve a balance between the two is an important pain point.

C-shaped structure and grinding method selection

The C-shaped body structure provides a solid foundation for the equipment. This design can effectively resist various forces generated during grinding and ensure long-lasting operational stability. This equipment supports continuous grinding. Faced with different workpiece materials and precision requirements, users can choose modes such as swing grinding or dual-station planetary grinding, which greatly expands the scope of processing.

Due to this flexibility, a machine tool can cope with a variety of process needs. Whether it is to quickly remove excess material or achieve fine grinding to obtain a high surface finish, the appropriate grinding strategy can be found. It is especially suitable for production workshops with a variety of products and frequent batch changes. It reduces the downtime caused by replacing special equipment, and the overall benefits are obvious.

Convenient maintenance and automation integration

A large window is designed on the back side of the machine tool. When replacing the grinding wheel, there is no need to carry out cumbersome disassembly. Automatic loading and unloading of grinding processing can be performed directly through the window, which greatly reduces the labor intensity and time cost of maintenance personnel. The grinding wheel is regarded as a consumable material, and the convenience of replacement directly affects the equipment utilization. This design appears to be extremely pragmatic.

The loading table uses a fixed style structure and is not a style that can be opened and closed. Although this design gives up some of the convenience of manual loading and unloading, it gains a higher degree of rigidity and a stable docking point for automated integration. Users can easily connect the hand that controls the machine or the conveyor belt to build an automated production line, avoiding the problem of decreased accuracy caused by frequent movement of moving parts.

CNC system and operating interface

The core control system uses the mainstream Siemens CNC system in the market, and its stability and rich functions are fully guaranteed. For domestic users, it can also be equipped with the Huazhong CNC system, thereby providing users with more choice space to adapt to different budgets and operating habits.

The human-computer interaction interface has been deeply customized and is not just a standard interface. It displays commonly used grinding parameter settings, grinding wheel dressing, automatic measurement and other functions with intuitive icons and menus. Operators who have undergone brief training can get started, reducing programming errors caused by complex operations.

Overall machine layout and structural stability

There is a solid overall frame, which is composed of three parts of the whole machine, namely the upper box, the lower box and the feeding table, which are connected and fixed in a vertical manner. This layout presents the characteristics of layer-by-layer stacking, which makes the center of gravity of the equipment lower and can effectively suppress vibration during high-speed grinding, thus providing a physical basis for high-precision machining.

All main load-bearing parts are made of high-quality cast iron and have been aged to eliminate internal stress. Precision processing technology and assembly technology ensure the contact rigidity and accuracy of each joint surface, which enables the equipment to maintain the initial geometric accuracy under long-term operation and high-load operation conditions.

Accuracy adjustment and calibration mechanism

The equipment abandons the traditional and complicated adjustment methods and uses an innovative three-point adjustment mechanism to adjust the angle of the upper box. By turning three precision screws, the parallelism and angle between the upper and lower grinding spindles can be accurately controlled. This process is intuitive and easy to quantify.

This function is extremely important to ensure the parallelism of both end faces of the workpiece. When the processing requirements change , automatic loading and unloading of the grinding process , or after the equipment has been running for a long time, the operator can quickly carry out the calibration work of the YHDM580D high-precision vertical double-end grinder, and does not need to rely on the manufacturer's engineers to come to the door. This not only saves maintenance costs, but also guarantees the continuity of production.

Efficient grinding wheel dressing and feed control

The disc-type grinding wheel dressing mechanism has the possibility of installing multiple sets of diamond stones of different sizes. During dressing, the disc rotates, causing multiple groups of oil stones to participate in the work in sequence or at the same time. Not only can the shape of the grinding wheel be quickly restored, but also complex dressing trajectories can be achieved. Its dressing efficiency is much higher than that of a single-point dresser.

The feed axis with fully closed-loop position feedback is equipped with a high-precision grating ruler. Based on this, the system can compensate errors caused by mechanical transmission in real time, thereby achieving precise feed with micron-level accuracy. The high-rigidity and high-torque electric spindle directly drives the hand grinding wheel. The vibration caused by the belt or gear transmission is eradicated, the surface quality of the grinding tool is improved, and the grinding process becomes smoother.

Spindle technology and cooling methods

The spindle adopts advanced electric spindle technology, and the motor rotor is directly integrated on the spindle, achieving "zero transmission" automatic loading and unloading of grinding materials . This structure has high speed, fast response, and because there is no intermediate transmission link, the operation is extremely smooth, fundamentally eliminating the vibration of traditional mechanical spindles caused by transmission chain gaps and elastic deformation.

There is high-pressure coolant supplied in the center of the spindle. The coolant can directly reach the core high-temperature part of the grinding area, and can quickly take away the heat. This situation not only effectively prevents the workpiece from being affected by thermal deformation, which affects accuracy, but also allows the equipment to use larger grinding parameters, thereby increasing the material removal rate and ultimately significantly improving the overall processing efficiency.
