1.5 A：The operation panel of each grinding head of the upgraded stainless steel round pipe tube polishing machine from Xieli Machinery has a digital ammeter display function. Operators can adjust the intensity of the grinding head through the display of a digital ammeter, which greatly affects the polishing effect and achieves the desired polishing standard.
     B：The ordinary stainless steel round pipe tube polishing machine does not have the function of digital ammeter display. The operator should judge according to years of experience, observe the awesome of the polishing head by visual inspection or listening to the polishing sound, so as to adjust the advance and retreat of the grinding head by turning the hand wheel. It greatly affects the polishing effect.

1.6 A：The upgraded stainless steel round pipe tube polishing machine from Xieli Machinery uses pure copper motors for each grinding head, which is generally not easy to damage. The machine has a longer service life and low maintenance costs.
     B：The ordinary stainless steel round pipe tube polishing machine may use an aluminum motor, which has a short service life and expensive maintenance costs.

1.7 A：The standard machine of the upgraded stainless steel round pipe tube polishing machine from Xieli Machinery is equipped with a water pump, water tank, and water pipe, and the machine is equipped with a fan dust removal port. Users can freely choose between wet polishing and dry polishing. Adding some grinding fluid during wet polishing can achieve cooling, dust removal, and rust prevention during the polishing process. When dry polishing, the machine can be paired with a dust removal fan to remove dust.
     B：The ordinary stainless steel round pipe tube polishing machine does not have water pipes, water tanks, or fan ports to remove dust, and the operator has a lot of dust during polishing.

1.8 A：The upgraded stainless steel round pipe tube polishing machine from Xieli Machinery can be made into a fully automatic CNC round tube polishing machine. By inputting the set diameter on the CNC screen and adjusting the machine with one click, the work efficiency is greatly improved. The polishing positioning of the fully automatic CNC round pipe tube polishing machine is more accurate, thus achieving a satisfactory polishing effect.

The stainless steel round pipe tube polishing machine of Xieli Machinery has multiple functions. It can not only polish the surface of round pipes or solid round rods, but also assemble different polishing wheels to achieve different polishing effects, such as wire drawing, rust removal, polishing, mirror surface, and so on.

The basic spare parts for the stainless steel round pipe tube polishing machine of Xieli Machinery include polishing wheels. There are many types of polishing wheels, such as thousand leaf wheels, steel wire wheels, cloth wheels, thousand hemp wheels, and so on.

Due to the high sales of stainless steel round pipe tube polishing machines by Xieli Machinery both domestically and internationally, the production department of Xieli Machinery has expanded its scale to produce stainless steel round pipe tube polishing machines. Generally, stainless steel round tube polishing machines are available in stock. In special cases where there is no stock available, the production cycle is 20-30 days.

1.1 A：The upgraded four sided rectangular square tube pipe polishing machine from Xieli Machinery has four adjusting pressure wheels for each set of grinding heads. This means that in this square tube pipe polishing machine with four sets of grinding heads, multiple adjusting pressure wheels can be seen, which can more accurately adjust the position of the pressure wheels, thereby accurately pressing the workpiece and making it more stable during the polishing process, achieving the ideal polishing effect.
     B：The ordinary four sided rectangular square tube pipe polishing machine has a total of two pressure wheels, which cannot completely press the workpiece. During the polishing process, the workpiece is easy to detach from the track and even get stuck, making it difficult for the workpiece to move forward.

1.2 A：The upgraded four sided rectangular square tube pipe polishing machine of Xieli Machinery adopts a thickened and weighted body cover, which improves the stability of the machine during the polishing and grinding process, thus achieving the ideal polishing effect. And it is safer during transportation and less likely to be damaged by collisions.
     B：The ordinary four sided rectangular square tube pipe rust removal and polishing machine has a thin body cover, low cost, and poor machine stability. The square tube has insufficient load-bearing capacity during the polishing process, and the unstable body can easily cause the square tube to deviate from the track during the polishing process, resulting in unsatisfactory polishing results. And during transportation, if there is a collision, the machine is easily damaged.

1.3 A：The upgraded four sided rectangular square tube pipe polishing machine of Xieli Machinery adopts pure copper motors, which have a longer service life and low maintenance costs.
     B：The ordinary square tube pipe polishing machine uses an aluminum motor, which is low-cost, resulting in a short service life and high maintenance costs.

1.4 A： The upgraded four sided rectangular square pipe tube polishing machine from Xieli Machinery can be made into an electric button adjustment method. Not only can it be adjusted with an electric button, but the polishing wheel can be rubbed left and right to polish the tube. The square tube pipe polishing machine can also be paired with an automatic waxing bucket to achieve mirror polishing effect. This polishing method improves polishing efficiency and enhances polishing effect. Suitable for large production enterprises and companies with high requirements for pipe quality.
    B：The ordinary four sided square tube pipe polishing machine only has two handwheels to adjust the forward and backward movement of the grinding head, and the adjustment method is simple and rough, which cannot accurately match the position of the tube. May result in unsatisfactory polishing effect. The affordable ordinary square tube rust removal, drawing, and polishing machine is more suitable for use in small manual workshops.

The basic spare parts for the four sided rectangular square tube pipe polishing machine of Xieli Machinery include polishing wheels. There are many types of polishing wheels, such as thousand leaf wheels, steel wire wheels, cloth wheels, thousand hemp wheels, and so on. Technicians will match the appropriate wheels according to the user's workpiece requirements to achieve the appropriate polishing effect. So, when customers purchase machines, they can buy enough spare parts to use.

The four sided rectangular square pipe tube polishing machine can be equipped with an automatic feeding machine device. Generally speaking, few people use square tube pipe polishing machines with automatic feeding because automatic feeding machines suitable for rectangular square tubes have complex structures and high costs, and few users use automatic feeding machines. However, Xieli Machinery has the ability to customize research and development design. If a user wants to match an automatic feeding machine with a square tube pipe polishing machine, Xieli Machinery's technicians will customize the automatic feeding machine according to the user's square tube specifications.
