Requirements for processing technology control of cylindrical grinder
1. Read the drawings clearly, check the shape and size of the workpiece to be processed, judge whether the workpiece to be processed is qualified and determine the processing allowance. Prepare the corresponding tools, measuring tools, and fixtures. The measuring tools must be calibrated accurately.
2. Reasonably select the processing technology and processing equipment (equipment accuracy) according to the workpiece residual quantity and process requirements.
3. According to the shape and process of the work piece, select the clamping method and process benchmark of the work piece reasonably.
4. * Clamp, first clean the * hole, apply grease, * The contact area of the angle of the hole is more than 85%, if the contact surface is too small, find your own supervisor section chief to arrange * Research and continue to use. * Natural damage, you should use the spare *, and report to the workshop planner for a new * subscription.
5. Fixture clamping, first correct the position of the fixture, process the fixture according to the process requirements, and then install the workpiece.
6. When grinding slender workpieces, you need to add a center frame.
7. According to the material nature, size and technical requirements of the workpiece to be grounded, select the grinding wheel reasonably: diamond grinding wheel for alloy, corundum or silicon carbide grinding wheel for steel; coarse-grained grinding wheel, high production efficiency, but the surface of the workpiece Rough; when grinding with a fine-grained grinding wheel, the surface roughness of the workpiece is better, and the productivity is lower. Under the premise of meeting the roughness requirements, the coarse-grained grinding wheels should be selected as much as possible to ensure higher grinding efficiency. Generally, coarse-grained grinding wheels are used for rough grinding, and fine-grained grinding wheels are used for fine grinding. When the contact area between the grinding wheel and the workpiece is large, a coarse-grained grinding wheel is used.
8. During the processing of the machine tool, strictly control the amount of feed. Observe the grinding conditions of the workpiece and the operation of the equipment through listening, watching, touching, smelling, etc., and find the abnormality, immediately stop the inspection and notify the maintenance team leader to report the repair in time. The reply is reported to the workshop office by the section chief, and the workshop office directly reports to the production department for record and the production department handles the equipment department. It is strictly forbidden to leave the work position when the machine tool is started.
9. The grinding wheel should be repaired in time after being blunt, and cannot be used forcibly to avoid safety accidents.
10. According to the processing requirements, when the grinding is close to the size, the amount of infeed should be reduced and the number of grinding times should be increased, and the detection frequency should be increased to ensure the machining accuracy and surface quality.
11. According to the drawings and process requirements, the equipment department adjusts the equipment, pays attention to the quality of the product at any time, and promptly reports the problem to the head of the construction section and relevant personnel if problems are found.
12. After the steel parts are processed, the dimensions can only be measured after the product has cooled down.
