MaintenanceMaintenance Instructions for the New Type Steel Pipe Deburring and Polishing Machine: 

1. Exterior Maintenance: Keep the surface of the polishing machine and motor, as well as the heat dissipation equipment, clean. Regularly clean the polishing consumables powder. Inspect and tighten handles, feed wheels, screws, nuts, and other components. Ensure the machine tool is in good condition.
2. Polishing Machine Whole Machine Inspection: Check all screws, belts, and tension levels on the polishing machine; looseness should be adjusted to the appropriate tightness. Inspect the wear on all bearings; replace if damaged, and ensure there is sufficient lubricant. Clean the guide rails thoroughly; no polishing material powder should be present on the guide rails.
3. Appliances: Timely cleaning of motor and electrical box. Appliances are fixed neatly and operate reliably. Check and tighten neutral connection devices.

Please noteNew Steel Pipe Deburring and Polishing Machine Precautions:  

1. Prior to connecting the power to this machine, it must be safely grounded. Do not use the machine if the external parts are not grounded to ensure safety.
2. The machine's distribution box is equipped with an emergency stop button, which can immediately halt the machine's operation when necessary.
3. Prior to startup, ensure the polishing wheel is securely assembled.
Always disconnect the power source when installing or replacing a polishing wheel.
5. When installing polishing wheels and fan blades, check if the page sheet angle is bending upwards.
6. Prior to turning on, the polishing wheel must rotate in the direction indicated by the arrow on the safety guard.
7. Parts must be placed in the part slot, where they will automatically rotate near the polishing wheel for polishing as they move forward.
8. Position the machine on a solid foundation and level it to ensure smooth operation.

During the operation of a large diameter external cylindrical polishing machine, the sample surface should be parallel to and evenly lightly pressed on the polishing disc. For tube polishing machines, be cautious to prevent the sample from flying out and to avoid new磨痕 due to excessive pressure. Additionally, allow the sample to rotate and move back and forth along the radius of the turntable to prevent excessive wear on the polishing fabric. Continuously add a fine powder suspension during polishing to maintain a certain level of humidity on the fabric. Excessive humidity will weaken the polishing effect of the abrasion marks, causing the hard phases in the sample to appear convex, and the non-metallic inclusions in steel and the graphite phase in cast iron to form.Tail drag phenomenon; when humidity is too low, friction generates heat, causing the sample to increase in temperature, reducing lubrication, the surface of the abrasive to lose luster, and even develop black spots, while lightweight alloys may scratch the surface. To achieve coarse polishing, the turntable speed should be low, *not exceeding 500r/min; the polishing time should be longer than the time needed to remove scratches, as the deformation layer also needs to be removed. After coarse polishing, the surface is smooth but lacks luster, showing uniform and fine abrasive marks under a microscope, which need to be polished out further. During fine polishing, the turntable speed can be slightly increased, and the polishing time should be sufficient to remove the coarse polishing damage layer. After fine polishing, the surface is bright as a mirror, with no visible scratches under bright field microscope conditions, but the abrasive marks can still be seen under phase contrast illumination. The quality of polishing by the polishing machine greatly affects the sample's microstructure and has gradually attracted the attention of experts.

Large Diameter External Diameter Polishing Machine is based on research of similar domestic modelsA semi-automatic production line for selecting and designing high-quality stainless steel round tubes, featuring an exterior surface polishing process. It is primarily suitable for the surface finishing treatment of metal tubes with various circular cross-sections. The complete production line equipment consists of three main parts: polishing machines, feeding racks, and discharging racks. In addition to the basic performance of similar models, this production line also has the following features:
ExplainLarge Diameter External Round Polishing Machines are primarily used for rust removal and polishing in industries such as metalworking, vehicle accessories, steel and wood furniture, instrumentation machinery, standard parts, and electroplating. They are suitable for polishing round tubes, round bars, and slender shafts.*Selection. The multi-station round tube polishing machine polishes workpieces without affecting their dimensions, making it particularly suitable for high-luster polishing of workpieces after centerless grinding. The multi-station round tube polishing machine is known for its high work efficiency, good surface roughness of workpieces, stable performance, and optional variable frequency control of the guide wheel speed, allowing for ideal processing regardless of the workpiece diameter. It is a preferred choice for polishing round tubes, round bars, slender shafts, and quartz rods.*
