Regarding the manufacturing method of the tailstock for external cylindrical grinding machines

2025-04-09

Regarding the manufacturing method of the tailstock for external cylindrical grinding machines.The workpiece spindle device and tailstock of the external cylindrical grinder are installed on both ends of the worktable. The tailstock is matched with the worktable through a sliding groove tenon structure. One end of the workpiece with a longer axial length is clamped by the workpiece spindle device, and the other end is supported by pushing the tailstock to drive the pointed shaft on the tailstock. Then, manual control is used to generate a pressing force on the workpiece. The workpiece spindle device drives the workpiece to rotate, and the grinding wheel device performs external surface machining on the workpiece.During the process of pushing the tailstock to the top, if the pointed axis on the tailstock moves quickly, it is easy to generate a large impact force on the workpiece, affecting the machining accu...

Precautions to be taken when grinding with a grinder

2025-04-09

Precautions to be taken when grinding with a grinder.1. Before driving, the machine tool should be carefully inspected, including checking the control mechanism, electrical equipment, and magnetic suction cups and other fixtures.2. After inspection and lubrication, conduct a test run and confirm that it is in good condition before use. When installing the workpiece, attention should be paid to aligning and tightening it. If the workpiece becomes loose during the grinding process, it may cause serious consequences such as flying out and injuring people or crushing the grinding wheel.3. When starting work, use manual adjustment to slow down the grinding wheel and bring it closer to the workpiece. The initial feed rate should be small, and excessive force should be avoided to prevent collision with the grinding wheel.4. When using a stopper to control the reciprocating motion of the worktable, it is necessary ...

Malfunction and repair of dynamic pressure bearings in surface grinding machines

2025-04-09

The outer circles of the front and rear bearings of the grinding head of the surface grinder are conical, and there are only three equally spaced flanges in contact with the inner taper hole of the bearing seat. There are 12 evenly spaced axial grooves on the bearings. When the bearings move axially, the radial clearance between the bearings and the shaft changes; When the bearing tightens, only the internal clearance of the three flanges becomes smaller, and the rest of the parts undergo elastic deformation to form three oil wedges, forming an integral three oil wedge dynamic pressure sliding bearing. The clearance of the bearing is small, the rigidity is good, and its lubrication method is self-priming lubrication. During use, there were occurrences of grinding head holding onto the shaft, vibration, and heating. 1、 Analyze the causes of the malfunction. 2、 Using a combination of scraping and grind...

Automatic balancing method for grinding wheel of grinder

2025-04-09

The vibration of machine tools has a significant impact on the grinding accuracy and stability of bearing groove grinders. In order to ensure the machining performance of the grinder, manufacturers have balanced the motor, pulley, and shaft system well before leaving the factory. The vibration of the grinder is mainly caused by the imbalance of the grinding wheel. Although it is balanced before leaving the factory, the grinding wheel itself is in a constantly changing process during the machining process, such as uneven wear during the machining process, different adsorption of coolant, correction of deviations, and installation errors and materials when replacing new grinding wheels, all of which can cause the quality of the grinding wheel system to deviate from its rotation axis and cause grinder vibration. This vibration will cause vibration patterns on the machined surface of the part, which has a signi...
