Adjusting and Improving Centerless Grinders by Combining Modern Technology

Release time:2023-09-01

Centerless grinding machine processing is a widely used machining method in mechanical manufacturing systems. In order to achieve low-carbon grinding by the grinding machine, the parameterization of CNC grinding for low-carbon grinding is studied. Establish a time objective function for the grinding process and a carbon emission objective function that includes electrical energy carbon emissions and grinding fluid emissions.

Then, considering the actual constraints of equipment performance and machining quality during the grinding process, an optimization variable is established based on the grinding speed and feed rate of the CNC machining process, with smaller machining time and low carbon emissions as the optimization objectives. In the past decade or so, advanced CNC grinding machine manufacturers around the world have been committed to improving CNC grinding machine technology and performance, and products that compete and surpass each other are constantly evolving. For example, composite processing grinding machines, follow-up CNC grinding machines, high CNC grinding machines, and so on.

In the next 20 years, manufacturers of CNC grinding machines will engage in fierce research and development competitions in the fields of CNC grinding machines, environment, and people. A new situation has emerged in the development of environmentally friendly low-carbon CNC grinding machines. The development of future grinding machines will shift towards upgrading to intelligent grinding machines and low-carbon green grinding machines to meet the environmental needs of modern mechanical processing. The current development trend of machine tools is high-speed, high-precision, composite processing, and multi-axis linkage.

Combining modern science and technology, we have further improved and adjusted the technology of centerless grinding machines. Now we have summarized several plans for reference:

1. The original friction track has been changed to a straight ball running track. It can effectively reduce the friction coefficient, improve the service life, and better achieve energy-saving effects.

2. The original trimmed grinding wheel has been changed to digital mode for control in the feed mode. Changed to analog trimming quantity as digital trimming quantity, which can effectively save grinding wheels and reduce material loss.

3. The grinding head component has been changed to a gravity balance type, which can reduce the light load operation of the motor, greatly reduce electrical energy loss, and the core thickness size of the workpiece is also more accurate. The screw pair can achieve a longer service life.

4. Install a servo motor to convert the original hydraulic cylinder control increment method to digital control. It can solve the unstable factors of the original hydraulic control and is modified into analog control as digital control, solving the problem of hydraulic oil leakage.

5. By using a servo motor, the original hydraulic cylinder control method can be changed to a CNC controlled feeding method. The thickness of the tool core during processing is relatively stable and will not be affected by temperature fluctuations. Centerless grinding machines can easily achieve multiple grinding and produce large-scale tools.
