Horizontal internal and external circular grinding machines are high-tech machine tools with high technical content. It has been developed and developed rapidly in recent years. It is mainly developed for the problem that medium and large cylindrical and conical workpieces cannot be clamped on the grinding machine at one time. Mainly based on the round table, there are different grinding heads around. The main structure has a turret-type column that can rotate 360°, and the grinding head is installed on different faces of the turret. This structure is relatively compact, but it is difficult to manufacture. In addition, there is a column that is integrally cast and integrated into the beam, which has good rigidity and is advantageous for improving the machining accuracy, and is suitable for use in a medium-sized machine tool. Some adopt the vertical axis double-column gantry structure, and the beam is equipped with a carriage and a grinding head, which is generally suitable for large machine tools.
The horizontal internal and external circular composite grinding machine meets the needs of users and conforms to the development trend of “high speed, compound, intelligent and environmental protection” of the world's machine tool industry. It is suitable for multi-variety small batch, variable variety and batch production methods. It can complete the compound grinding of the inner circle, outer circle, end face and cone surface of the part by one clamping. It has the characteristics of high efficiency, high precision and convenient operation. The combination of the machine tool is strong, and the ATC grinding wheel library can be installed. APC exchange workbench, AMS automatic measurement system and robotic components are easy to automate production. At the same time, due to the small clamping force of the vertical arrangement, the fixture is relatively simple, the floor space is small, and the purchase cost of the equipment is saved. The machine is suitable for grinding and processing discs, short shafts, sleeves and other parts with small aspect ratio, especially suitable for auto parts, gear processing, bearings and other industries, multi-variety, small batch parts processing. Horizontal internal and external cylindrical composite grinding machines can be widely used in multi-volume, multi-variety and multi-standard finishing grinding of cylindrical, conical, ball bearing, outer ring, raceway and end surface; also suitable for gears, High-precision grinding of parts such as sleeves.
Maintenance method of horizontal inner and outer circular composite grinding machine:
1. Maintenance of the external appearance of the grinding machine: the appearance of the equipment and the motor, the surface of the heat-dissipating equipment must be kept clean, and the polishing consumable powder should be cleaned regularly.
2. Check and tighten the handles, feed handwheels, screws, nuts and other parts to keep the machine in good condition.
3, the inner and outer round composite grinding machine inspection: check the screw parts of the grinding machine, the belt, the degree of tightness, the loose should be adjusted to the appropriate.
4. Check if the wear level of each bearing should be replaced if there is any damage, and whether the lubricating oil is sufficient.
5, the guide rail should be cleaned, the rail can not be equipped with polishing consumable powder.
6, electrical appliances: regularly clean the motor, electrical box. The electrical device is fixed and reliable.
7. Check and tighten the zeroing device. Check the button switch of the horizontal inner and outer cylindrical grinding machine. If there is any problem, replace it immediately to avoid unnecessary danger.
