The two brakes are not synchronized, which means that the motor and the traction wheel are not synchronized. Because the quality of the HD type hydraulically controlled reversing valve is too poor, the internal reversing ball and ball bowl are not tightly sealed, and the hydraulic oil is leaked, resulting in a pressure difference. When the two variable pumps are reversed, the output pressure oil cannot be synchronously output, resulting in a time difference between the torques outputted by the two hydraulic motors, that is, acting on the respective drive gears one after the other, thereby causing the main drive gear and the traction wheel to be The chips can be discharged along the surface to be machined; the blade must be ground straight and the roughness should be small. The tool material is: the blade grade is W18C4rV, and the hardness after heat treatment is HRC6366. The arbor is made of elastic knives. Precautions during processing 1 When using the tool holder, be careful that the pressure between the support block and the workpiece of the tool holder should not be too large. If the pressure is too large, the workpiece will be in a "bamboo" shape due to the inconsistent forces on the workpiece at different machining positions. 2 During machining, whether it is low speed cutting or high speed cutting, it is necessary to use cutting fluid to reduce the temperature of the workpiece. Generally, an emulsion with better cooling performance is used as the cutting fluid. 3 The tool should be kept sharp at all times to reduce the heat of cutting. 4 When processing, apply some grease to the tool holder support block to maintain a good slip between the workpiece and the support block.
Bimetallic barrel refers to bimetallic screw and barrel, mainly used for processing engineering plastics, fluoroplastics, polysulfone, PPO special types of plastics, etc.
