Force Control Grinding Technology Analysis

Release time: 2022-01-10

Now the application of robots is more common. Among the automation equipment, the utilization rate of automatic grinding equipment is also increasing and increasing.

Robot grinding is mainly used for high-precision grinding and polishing operations in the sanitary industry, industry, auto parts, industrial parts, medical equipment, and civilian products. Its grinding function is mainly used for casting surface grinding, deburring of edges and corners, welding seam grinding, deburring of inner cavity and inner hole, and processing of orifice and thread.

Compared with manual grinding, the use of industrial robots can achieve efficient and stable continuous operation according to the edited path, helping enterprises to effectively improve production efficiency, product yield, and reduce production costs. In the case of complex and diverse workpiece materials, workpiece molding involves many processes, covering sheet metal, stamping, casting, injection molding, CNC, etc. Due to differences in material characteristics and molding methods, workpieces will have dimensional tolerances, but the data size difference.

Since industrial robots usually run accurately according to the debugged path, the running path is fixed and the error is extremely small, when there is a slightly larger tolerance on the surface size of the workpiece, or a slight deviation in the positioning position, the grinding effect will fluctuate greatly, even There will be situations where the polishing is not enough, or the polishing is excessive due to excessive pressure, resulting in a low yield rate and mass production cannot be realized.

The main advantages of the robot with force-controlled grinding tools:

(1) Improve the grinding quality and product finish to ensure its consistency;

(2) Improve productivity and allow 24-hour continuous production;

(3) Improve the working conditions of workers, allowing them to work in a harmful environment for a long time;

(4) Reduce the requirements for workers' operating skills;

(5) Shorten the cycle of product modification and replacement, and reduce the corresponding investment in equipment;

(6) Re-development, users can perform secondary programming according to different samples.

Generally speaking, many castings need to be manually deburred, which is not only time-consuming, the grinding effect is not good, the efficiency is low, and the hands of the operator are often injured. The air pollution and noise in the deburring work site will damage the physical and mental health of the operator. The grinding robot is equipped with different grinding machines and grinding heads according to the smoothness requirements of the processed parts. It has the characteristics of long-term grinding operation, high productivity, high quality and high stability of the product.
