Operation Methods of Double Disc Grinding Machine

Double disc grinding machine is a high-precision machining equipment used for simultaneous grinding of two endfaces of a workpiece to achieve high parallelism, high flatness and high surface quality. In order to ensure the operation safety and processing quality, the operator must strictly follow the operating procedures.

Before operation, it is first necessary to check the equipment to ensure that the components are intact, the connection parts are not loose, and the hydraulic system, lubrication system and cooling system work normally. At the same time, check whether the grinding wheel is intact, whether the installation is firm, whether the electrical system is normal, whether the grounding is reliable. For the workpiece, it is necessary to check whether its size, shape and material meet the processing requirements, and clean the surface of oil, rust and other impurities. According to the shape and size of the workpiece to choose the appropriate fixture, to ensure that the clamping firmly. Finally, set the grinding parameters according to the workpiece material and processing requirements, including grinding wheel speed, feed speed, grinding depth, etc., and set the coolant flow and pressure to ensure adequate cooling and lubrication.

When switching on the machine, start the hydraulic system, lubrication system and cooling system first, and start machining after the grinding wheel spindle runs smoothly. When tool setting, manually move the grinding wheel so that its end face is in slight contact with the end face of the workpiece, and use a tool setting instrument or other tools for accurate tool setting to ensure that the grinding wheel is parallel to the end face of the workpiece. During the grinding process, start the automatic feeding system, observe the grinding status, adjust the parameters in time to ensure the processing quality, and pay attention to the use of coolant to prevent the workpiece from overheating and deformation. After processing is completed, use micrometers, parallel gauges and other tools to measure the workpiece size, parallelism, flatness and other parameters, and adjust the grinding parameters according to the measurement results to ensure processing accuracy. When stopping the machine, turn off the automatic feeding system first, stop the grinding wheel spindle, then turn off the cooling system, lubrication system and hydraulic system, and finally clean up the machine tool and working area.

When operating the double disc grinder, the operator must be professionally trained, familiar with the structure of the equipment and operating procedures, and wear protective glasses and other labour protection articles. It is strictly prohibited to overload the equipment to prevent equipment damage and personal injury. Regular maintenance of the equipment to ensure the normal operation of the equipment. Abnormal conditions should be found immediately stop the machine to check, troubleshooting before continuing operation. In addition, it is strictly prohibited to bring hands or other objects close to the grinding wheel during operation, and the power supply must be cut off and special tools must be used when replacing the grinding wheel. Regularly check whether the grinding wheel is cracked, broken, etc., timely replacement, and keep the work area neat and clean to prevent accidents such as slipping.

In short, double disc grinding machine operation needs to be carried out in strict accordance with the regulations, the operator must have certain professional knowledge and skills. Only the correct operation and maintenance of equipment can ensure processing quality and operational safety.
