Grinding and deburring is one of the important processes in the post-processing of aluminum alloy die castings, and it is also a process that is difficult, labor-intensive and time-consuming. At present, customers of die casting plants are facing many difficulties in manual deburring. Manual grinding and deburring has low work efficiency, unstable workpiece grinding quality, difficult recruitment and expensive labor, resulting in low workpiece grinding efficiency and high overall cost.
In order to meet the needs of customers in automatic grinding and deburring, Dongguan Lingrui Machinery Co., Ltd. (hereinafter referred to as “Dongguan Lingrui”) uses its own precipitation in motion and control, vision and sensing technology, combined with its many years of technical achievements With the accumulation of practical experience, we took the lead in launching a six-axis intelligent grinding machine in the industry many years ago, and comprehensively promoted it in the industry to provide efficient solutions for grinding and deburring of die castings of different sizes.
Mr. Deng Sanjun, general manager of Dongguan Lingrui Machinery Co., Ltd., said that Dongguan Lingrui has been deeply involved in the field of die-casting automation for more than ten years, and has accumulated rich experience in die-casting automation technology and its production and application practice. A few years ago, the company introduced advanced automatic grinding and deburring technology from Japan. After more than two years of exploration and research and development, the company successfully launched a six-axis intelligent grinding machine in the domestic market. The equipment realizes five-axis linkage, intelligent automatic grinding and deburring, which greatly saves labor, improves production efficiency, shortens the customer’s delivery cycle, and enhances the competitiveness of customer enterprises.
Dongguan Lingrui six-axis intelligent grinding machine
According to reports, Dongguan Lingrui six-axis intelligent grinding machine has a compact structure, stable operation, flexible movement, fast installation, small footprint, multi-axis linkage, and can meet the multi-faceted grinding of special-shaped die castings. The overall rigidity of the equipment is strong, the precision is high, the grinding quality is stable, and the efficiency is high; it can carry a variety of tools, and the tool change is fast, which can meet the grinding of different burrs, particles, and slag-covered nozzles. In addition, the spindle cutter head is equipped with spray and air blowing devices, which can effectively cool and lubricate the tool and increase the tool life.
In terms of operation, Lingrui six-axis intelligent grinding machine is easy to debug and operate, quickly put into production, fast product switching, and high production efficiency when changing lines. In addition, the machine has a variety of spare interfaces, and auxiliary equipment can be added in the follow-up to achieve “unmanned” production. In addition, it is equipped with video monitoring and video storage functions, which can realize remote monitoring and operation. In terms of use, the intelligent grinding machine adopts fully enclosed processing to reduce noise and dust pollution to the environment and reduce harm to personnel. Equipment maintenance is simple and fast, energy-saving and environmentally friendly, and the maintenance cost is low. It not only conforms to the current development concept of green economy, but also minimizes pollution and helps achieve the national dual-carbon goal.
Dongguan Lingrui is constantly pursuing technological progress, combining user feedback and practical experience, and continuously optimizing the design on the basis of existing models, so that the six-axis intelligent grinding machine continues to strengthen in terms of stability, easy operation, durability and safety. Mr. Deng Sanjun said: “Recently, we have successfully launched the fourth generation model. Compared with the previous generation model, the overall performance has been greatly improved. The first is system optimization, the polishing accuracy has been improved, and the program editing is simpler and faster than the previous generation. , improve the stability of the machine operation. Secondly, on the basis of the previous generation, the components are added in many aspects – safety grating, safety door switch, sealing strip, which enhances the protection level, improves the safety factor of the whole machine, and ensures the safety of the operator. Safety; the effective stroke of the equipment is increased, making it compatible with more product processing; the electric box has added a temperature control system, which effectively protects the electronic components of the electric box; the spindle has added a permanent magnet spindle, which has greater cutting force and longer service life Longer, more efficient grinding.”
It is worth mentioning that the Lingrui six-axis intelligent grinding machine has a high degree of flexible grinding characteristics. Mr. Deng Sanjun said that the intelligent grinding machine highly imitates manual grinding, automatically adjusts the grinding strength, is relatively flexible and efficient, and effectively reduces the scrapping rate of grinding; it can carry a variety of flexible tools, such as: floating vibration grinder, floating file machine, floating Steel brushes, floating grinding discs, etc., can effectively remove various burrs, particles, and burrs; the radial floating file can be radially avoided in the process of deformation of the workpiece or processing of irregular products, preventing over-cutting of products and reducing damage to the product. Tool damage; Axial floating head can be effectively used for product end face particles, turtle cracks, drape, parting line, watermark grinding, to prevent product deformation and excessive product grinding and damage to tools; axial floating vibrating grinder for workpieces The appearance is finely polished to improve the surface finish; the synchronous axial floating vibrating mill has the same effect as the pneumatic vibrating mill, but is driven by a synchronous motor to reduce noise, and the brushed chassis can be installed 2-5 inches.
At present, the commonly used automatic grinding and deburring solutions on the market are traditional robotic deburring equipment. Mr. Deng Sanjun said that compared with robot deburring, the six-axis intelligent grinding machine is easy to operate and has relatively low requirements for employees; the system is simple, and the 3D import accuracy is high; the line changing operation is fast, the protection level is strong, and the safety factor is high; closed Processing, energy saving and environmental protection, waste can be recycled; long service life, simple maintenance and low cost.
In order to meet the grinding needs of workpieces of different sizes, Dongguan Lingrui has developed a number of different types of intelligent grinding machines, namely LR-ZM6A-35, LR-ZM6C-65, LR-ZM5C-120. Combined with the size range of the workpiece, various types of equipment are equipped with different workbenches, effective strokes and body heights. The effective stroke of LR-ZM6A-35 is 350mmx350mmx380mm, mainly for some small tonnage die-casting products, such as motorcycle accessories, small household appliances, and small communication parts. The effective stroke of LR-ZM6C-65 is 650mmx550mmx440mm, mainly for die-casting products under 2500 tons, such as auto parts, communications, home appliances, etc. The LR-ZM5C-120 type has an effective stroke of 1200mmx1200mmx1000mm, mainly for large die-casting parts, such as 5G communication and automobile brackets.
