Create excellent "fine" products, highlighting technological advantages

Interview with Luo Dinghao, General Manager of Dongguan Dengsheng Precision Machinery Co., Ltd. -
The bond with the YYC rack
Taiwan's machinery manufacturing industry has been receiving worldwide attention. Since 2008 , Mr. Luo Dinghao has first introduced the “YYC” rack made in Taiwan to the mainland. Become a symbolic move in the field of racks
As a leader in the rack manufacturing industry, YYC grinding racks have long been known in the industry for high precision and high reliability materials.
In the mainland market, YYC products provided by Dengsheng Precision are also recognized by the users for the following special advantages: The highest precision of the grinding rack can reach DIN5 grade accuracy and surface roughness of 0.8 ; not only provides a straight rack, but also provides an oblique angle at any angle Tooth grinding racks; not only the production of standard catalog products, but also custom processing according to the needs of users, in the entire design and manufacturing process to help customers enhance the value.
Nowadays, YYC products have been used in CNC machine tools, milling machines, drilling machines, factory automation rapid transfer mechanisms, robotic arm grabbing mechanisms, intelligent stereoscopic warehouses, etc., and can provide M1.5~M12 different modular racks. , YYC products have been completely replaced in some occasions ball screw, cylinder, linear motor and other linear transmission products, very cost-effective. In the global market, YYC products are also exported to 26 countries and regions with excellent performance . And Dengsheng Precision is the only company with YYC racks currently stocking more than 1 million in mainland China .
At present, many domestic companies are also manufacturing racks, but the breakthrough is stuck in accuracy and materials. Taking materials as an example, the current general rack material for the Mainland is No. 35 steel. The Taiwan rack common material is No. 45 steel. In 2013 , this steel will also mention No. 50 , which means that the lifespan and hardness of the rack will be a new level. At the same time, the mainland rack has not been tempered on the hardening process, and the tooth surface is brittle and not tough. In general, the mainland racks are basically offline, and it still needs time to improve.
However, due to the initial positioning of high-end, so its competitors naturally avoid mainland enterprises.
In those international racks that can be regarded as competitors, Ruiqi Industry and Trade has consistently won the recognition of users with high inventory and fast delivery. In addition, Ruiqi Industry and Trade also has its own characteristics in some key service equipment. For example, Dengsheng Precision has its own straightening machine that can correct deformed racks.
Talking about the future development of racks, Mr. Luo Dinghao said that the entire market is currently on the line, especially in the automation field. With the increase in per capita wages and the demand for speed, racks will have a broader perspective. On the other hand, from the viewpoint of product substitution, racks are gradually replacing the screw due to the wide range of modulus, occupying the market share of the screw. Of course, due to the higher price of the rack than the screw, what Ruiqi Industry and Trade currently needs to do is to allow users to understand and accept the long-term benefits of selecting a rack.
High-end reducer positioning high cost-effective to win the market
Compared with the high-end agents and promotion of racks, the production and development of reducers pay more attention to independence and independence. This is also a solid step towards the autonomy of the brand.
Due to the low threshold of the speed reducer, the most common problem encountered by Deng Sheng Precision's former reducer is that the product quality varies greatly and the defect rate is high. At the same time, in the market, companies that cut corners and labor because they want to reduce costs also exist in large numbers, and then many " sequelae " emerge.
Therefore, at the beginning of the development of the autonomous reducer, Dengsheng Precision positioned high-end, tried to win customers with high quality and reduced after-sales service.
In general, to measure the quality of reducer products, we will consider the accuracy of stability and the number of broken shafts. In order to ensure the accuracy and stability of the product, Ascenda Precision checks the source of the design. At present, 3 members of Dengsheng Precision Design Team have extensive experience and expertise in the field of reducer. In order to ensure the constant axis of the reducer at high speed, Ruiqi Industry and Trade has applied many high-cost materials. At some points in the process, Deng Sheng Precision is the cost of the next step. A data shows that in the broaching process, other enterprises reducer internal gear ring broach only need 4 yuan, and Deng Sheng precision use of the tooth press lathe needs 120 yuan.
The increase in cost will affect the price of the product to some extent. However, its price/performance is unmatched by ordinary speed reducers. This is also one of the mysteries of the high-end of the St. Seine precision reducer.
Another mystery lies in the fact that Dengsheng Precision Reducer is not limited to the development of ordinary planetary reducers. In 2013 , the BSG/BSF series harmonic speed reducer developed by Tengsheng Precision Co. , Ltd. lasted for three years was officially launched. Its features are more precise. Compared to the three planetary gears in the center of the planet, the middle of the harmonic reducer is designed as a flexible wheel. When the reducer is running, the flexible wheel made of alloy steel material will be deformed to meet the high function, high speed, high load capacity, and high speed. The need to accelerate technological innovations such as density and miniaturization.
As far as is known, Dengsheng Precision is the sixth company in the world to develop a harmonic reducer. In application, positioning is in the field of robotics. Since the life cycle of harmonic reducers is generally maintained at 10,000 hours, Dengsheng Precision has positioned the market more precisely as the robot maintenance market.
Mr. Luo Dinghao commented on this market and considered it as “when the juicer is being squeezed open ” : Because the life of the harmonic reducer is limited, starting from the maintenance market, on the one hand to avoid the price war, on the other hand, the maintenance market does exist. More space, such as the electronics factory in Taiwan, 1000 mechanical arm is very common, if you want to do maintenance, maintenance market capacity is about 5 million yuan, supply one or two larger customers is enough to make the product survive.
At present, the sales volume of this product in Taiwan is greater than that of the mainland. In the Mainland, Dengsheng Precision entered the market from June , and is now negotiating with some international first-tier robotics companies. At the same time, he said, Dunsan Precision will also introduce faster angular speeds, higher precision, and variable speed two-speed spindle speed reducers. At present, there are three companies that have successfully developed products in this field, and the main market in the future will be machine tools.
Another masterpiece of servo system 2013
The promotion of servo system is another focus of Dengsheng Precision in 2013 . Currently, the servo system used by Assun Precision is mainly Fanta Technology's SSD and CSD servo system. It has features such as stable speed, high torque, low vibration, and easy and fast. It can be used to meet customer's functional requirements such as torque, speed, positioning and synchronization. , And single rotation has elastic absolute resolution can be adjusted, power from 400w to 50KW .
Compared with the European system servo, its outstanding advantage lies in the price. Compared with Japanese servos, the outstanding advantage is that the function is fully open, the motion control function is provided in the drive, and the human machine can be used. Its development engineers are from Europe. The main architecture and main chip also use the most advanced parts of Europe.
Although this series of products entered the mainland market this year, it has long been used in Taiwan, the Middle East, Southeast Asia, and Brazil.
The product is 485 bus, Mr. Luo Dinghao revealed that in October they put CAN bus products to market in 2014, the servo will EtherCat bus to compensate for incomplete on the bus.
In addition, Mr. Luo Dinghao also talked about the confusion he encountered in promoting the servo: At present, the mainland's servo market is mainly price-driven. On the one hand, the user requires good technology, and on the other hand, the user requires the product to be cheap. To make them satisfied, they can only step by step, and through communication, let them understand and accept the concept of a set of man-machines, a set of servos that can operate, and the overall cost reduction. At present, Ascenda Precision will focus on the field of high-speed displacement robots such as picking.
At the same time, taking into account factors such as large motor variables and uncontrollable sales prices of motors, Ruiye Industry and Trade is adjusting the previous strategy of supporting the sales of motors and drives, and instead cooperates with domestic motor companies to provide them with drives. Related projects are in negotiation.
Talking about the future development of servo, Mr. Luo Dinghao thinks that high-power servo is an important trend, and at the same time it will focus on the improvement of demagnetization, torque and life of the motor.
The ever-changing global economy is like a storm. Passion and risk coexist, and opportunities and challenges coexist. Dengsheng Precision aims at market innovation, takes customer service as its tenet, and strives to create excellent products. It is committed to becoming a world-renowned professional transmission equipment supplier and providing quality product and service solutions for more machine tool companies.
