Conveyor-type Square Tube Grinding MachineYL-APM-077-4
1. Application Areas: Suitable for the surface polishing and grinding of square tubing made from materials such as stainless steel and aluminum alloy.
2. Functional Features:This four-station grinding and polishing machine is equipped with four sets of grinding heads (corresponding to four distinct processing stages), designed to grind all four faces of a square tube simultaneously. Each processing stage utilizes a set of four grinding heads—positioned at the top, bottom, left, and right—to address the respective surfaces. For every additional processing stage added, a corresponding set of four grinding heads is incorporated into the system.
3. Polishing Wheels: The machine is compatible with a wide variety of grinding and polishing wheels, including sisal wheels, cloth wheels, abrasive cloth wheels, nylon wheels, flap wheels, and others.
Optional add-ons, such as an automatic wax spraying system and a dust collection unit, can be freely integrated into the configuration.
4. Operation Instructions: The machine offers simple and user-friendly operation. Once the positions of the individual grinding heads have been set during the initial configuration, a single operator is all that is required to manage the continuous loading and unloading of workpieces. With its straightforward operation and streamlined structure, the equipment requires only one attendant to oversee fully automated grinding processes, making it a highly cost-effective automated polishing solution.
5. Configuration:Equipped with an automatic loading and unloading rack, enabling fully automated operation.

1. The accompanying image illustrates the product's appearance when fitted with its protective enclosure. Since the grinding process generates a significant amount of dust, the enclosure—in conjunction with an exhaust port—allows the dust to be extracted and channeled into a dust collection system for proper disposal.
2. If the machine is utilized for surface polishing using cloth wheels, an optional automatic waxing system—capable of applying either spray wax or solid wax—can be added. This feature eliminates the need for manual waxing, thereby saving labor costs.
3. By incorporating an automatic loading and unloading rack, the system can achieve fully automated operation—encompassing automatic product loading, automated grinding and conveying, and automatic product unloading.
