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.

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.

     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.
