Brake Pads Electromagnetic Disc Grinder

Machine Overview and Functionality

The Electromagnetic Disc Grinding Machine is specifically engineered for the surface grinding of diverse brake pads. In a departure from conventional methods, it employs electromagnets to firmly attach the brake pads to the grinder disc, eliminating the need for traditional fixtures. This innovative design allows for simultaneous fine grinding, coarse grinding, and dust cleaning operations. Additionally, it features stepless speed regulation, granting operators the freedom to precisely control the grinding speed. The machine is designed with user-friendliness in mind and is capable of ensuring stable quality and high-efficiency output, even during large-scale mass production runs.

Grinding Capabilities
Coarse Grinding
The machine is highly proficient in conducting the coarse grinding process. This initial stage of grinding is essential for quickly removing excess material and shaping the brake pad to the approximate desired form. It uses a powerful coarse grinding head with a motor power of 4KW and a rotational speed of 6000 rpm, ensuring efficient material removal.
Fine Grinding
For achieving a smooth and precise surface finish, the machine enables accurate fine grinding operations. The fine grinding head, also powered by a 4KW motor and operating at 6000 rpm, is designed to delicately refine the surface of the brake pad, meeting the strict quality requirements for brake pad performance and durability.
Dust Cleaning Options
To maintain a clean working environment and prevent the accumulation of debris that could affect the grinding process and the quality of the finished product, the machine offers two dust cleaning options: a brush or air blow. The brush head, powered by a 0.55KW motor with a rotational speed of 3000 rpm, effectively sweeps away the grinding residue. Alternatively, the air blow method can be used to forcefully remove the dust particles, ensuring that the grinding area remains clear and the quality of the surface grinding is not compromised.
Technical Specifications
Production Capacity
The machine exhibits an impressive production capacity, capable of processing between 1400 and 1600 brake pad pieces per hour. This high throughput rate makes it suitable for meeting the demands of industrial-scale production, where speed and efficiency are crucial factors in maintaining a competitive edge.
2. Surface Accuracy
The machine is designed to maintain a high level of surface accuracy. The horizontal run out is within ≤0.05mm, ensuring that the ground surface of the brake pad is flat and smooth, meeting the strict tolerances required for proper brake pad function. This level of precision is critical for ensuring the safety and performance of the brake pads in automotive applications.
Electromagnetic Sucker Specifications
The voltage of the electromagnetic sucker is 110V, which is sourced from external industrial electricity (utilizing 3-phase, 220V). The angle of the suction force area is at least 180° in a sectorial shape, ensuring a strong and reliable hold on the brake pads during the grinding process. The angle of the loading and discharge area is up to 180° in a sectorial form, facilitating easy placement and removal of the brake pads. The machine also features a non-magnetic area of 150° and a magnetic area of 210°, which are carefully designed to optimize the magnetic field distribution and the overall performance of the electromagnetic attachment system.
Magnetic Disc Power and Speed
The magnetic disc driving power is 1.5 KW with frequency control, allowing for precise adjustment of the magnetic force and the rotational speed of the disc. The magnetic disc standard rotational speed is adjustable from 1/4 to 8 rpm in a stepless manner, providing operators with the flexibility to adapt the grinding speed to the specific requirements of the brake pads being processed. This fine-tuned control over the magnetic disc speed is essential for achieving consistent and high-quality surface grinding results.
5. Grinding Table Dimensions
The diameter of the grinding table measures either 600mm or 800mm, with the option for customization. The size of the grinding table affects the area that can be processed at once and is chosen based on the specific production requirements and the size of the brake pads being ground.
