Sany Electric Tool Operator is installing Walter Tap
As a wholly-owned subsidiary of Sany Group, the largest construction machinery manufacturer in China and the fifth largest in the world, Sany Electric focuses on the R&D and manufacturing of new energy equipment products with wind power as the core, adhering to the “Quality Change World†of Sany Group. "The core concept is to provide customers with the highest quality products and services. For energy production equipment and component manufacturers, maximizing energy output at the lowest possible production cost is tantamount to defeating the enemy. At this point, it is significant to economically and accurately machine parts of different materials. It is precisely because of this vision that Sany Electric has found and selected Walter, and their cooperation has built a mutually beneficial win-win situation.
It is well known that the fan structure is complex and the manufacturing precision is high. The key parts of the main components such as the hub, the main shaft, the gear box, the support frame and the slewing support are required to be processed by threads. "If a worker wants to do something good, he must first sharpen his tools." As a tool for metal thread processing, the tap is naturally duty-bound.
The challenges of component performance and materials. "The choice of taps is not easy, we have put a lot of effort into this," said Li Nan, an electrical tool engineer at Sany. On the one hand, the characteristics and performance of the core components of the fan determine its high precision for the tap, accuracy, reliability and stability. In wind turbines, the rotor hub forms the interface between the rotor and the drive train. From a functional point of view, it is closely connected to the mechanical drive train. All rotor forces, physical stresses and torques are concentrated in a point-like manner on this component. Correspondingly, the component is subjected to very high loads, an absolutely accurate and stable and reliable cutting process, which is indispensable for the production of a function-effective, defect-free rotor hub. In addition, the threading of any part of the gearbox, main shaft, support frame and slewing ring has correspondingly high requirements. On the other hand, due to the comprehensive consideration of performance and cost, at present, key components of wind turbines (such as rotor hubs) are produced from ductile iron materials, and their high plasticity, high toughness and high strength are used for internal thread processing. The tap is no doubt a challenge.
Trinity Tool Engineers said that although Walter's tap products are more expensive than other good brands on the market,
Walter stands out in a number of corporate bids. Sany Electric has invited a number of tool manufacturers to participate in the bidding, Walter became one of the first outstanding cooperation suppliers. Of course, this does not mean that Walter’s relationship with Sany has been rock solid since then. As a company that attaches great importance to quality, the concept of “Quality Change the World†is truly reflected in every aspect of production practice. In actual production, even if the same workpiece and parts are processed, Sany Electric will also select different brands of tools to carry out all-round comparison of process parameters, comprehensive energy consumption, comprehensive cost, technical support and service standards. After a "rigorous" comparison, Walter finally relied on the complete, precise, reliable and economical characteristics of the product to "stand out". Li Nan said, "Although Walter's tap price looks higher than other manufacturers, the quality is very good, the processing efficiency is high, and it is more reliable and durable. Especially in the high-precision thread tapping, the second and third-line brands are difficult to meet the technical indicators. We choose Walter more."
In the case that China's domestic wind turbine core components are produced from ductile iron materials, products that can cut this material perfectly are naturally more likely to be favored. Currently, in order to cope with the relatively complicated and rigorous industrial environment, ductile iron has many grades, and has a wide range of mechanical properties and physical properties. Most spheroidal graphite cast iron castings, such as ISO 1083, are mainly produced in non-alloyed state. This range includes high-strength grades with tensile strength greater than 800 N/mm 2 and elongation of 2%; the other extreme is high-plastic grades. The elongation is more than 17%, the tensile strength can be as low as 370 N/mm2. At the same time, in order to meet the special needs, many countries have developed austenitic-bainitic ductile iron, which is called ADI internationally and has a tensile strength of 1000N/mm2. It can be seen that the tensile strength of the ductile iron material has a large span. “Paradur ® Eco -Plus / Prototex ® Eco HT is made of high-performance powder metallurgy high-speed steel for long-cut and short-cut materials with tensile strengths of approx. 200N/mm2 to 1300N/mm2, even for extreme ductile iron grades. Nothing to say." Walter engineer introduced.
Li Nan said: "Walter Prototyp Prototex ® X·pert P has a wide range of products, and almost any processing task can find a suitable solution. The markings on the handles ensure reliable configuration. The processing of long chip materials has high process reliability and is a veritable professional tool for precision thread processing of steel parts."
At the same time, another person in charge of Sany Electric said, “In terms of business, economic value and ecological value are the first factors to consider when choosing a product. Prototex ® Eco Plus chamfered area optimized groove shape improves tool life High cutting speed and long tool life allow for fewer tool changes and optimum machine utilization. The Paradur ® Eco CI indexing TiCN multilayer coating enables higher cutting speeds and longer tool life. The manufacturing cost of each thread is reduced. In addition, products such as Paradur ® Eco-Plus / Prototex ® Eco HT and Prototex ® Eco Plus are suitable for micro-lubrication (MQL), which reduces the consumption of cooling lubricant and reduces the cost."
After several years of cooperation, the cooperation between Walter and Sany Electric has become more stable, and the tap series products have extended from the application of the fan field to the field of drilling machines. “Walter has a wide range of tools and can be used in a variety of occasions. At the same time, the products are mature and stable, with high reliability and high cost performance.†The person in charge said, “As long as Sany has tool requirements, we will first consider Walter. ."
If it is said that the original intention of Sany's choice of Walter is to admire the Walter brand strength and industry reputation, then, after several years of cooperation, Sany really feels its high performance to support its brand strength and industry reputation. High efficiency, strong after-sales and service expertise. As one of the tool engineers at the Trinity Workshop said: "Walter, some are not just products."
The concept of excellence. Walter's product development department maintains a close working relationship with the customer's R&D department and machine tool manufacturer, as well as between universities and workpiece material developers, and analyzes the challenges that the industry will face in the next 5 to 10 years. Immediately research the corresponding solutions and always maintain the vitality of technological innovation. And while they regularly introduce new products, they will still improve the original products and create maximum value with minor changes. For example, it is difficult to eliminate debris in the process of tap processing, and the operator needs to clean it regularly, which consumes manpower and affects working hours. Walter attached great importance to this small problem and organized a technical team to conduct research and found that this problem is closely related to the helix angle of the tool, the rake angle of the blade and the chip flute. Walter technicians have determined the optimum angle by adjusting these indicators, which reduces the damage rate of the tap and reduces the number of operator treatments, which reduces the customer's processing cost. Another example is Walter's development of coating technology, which has a service life that exceeds 70% of the opponent's life. According to comprehensive data, Sany has only benefited from the high efficiency, tackling and reducing consumption of Walter.
Cost-effective. “The impact of tool prices on the overall processing cost is almost negligible. Therefore, we do not use pure tool prices to measure the value of a product, but rather to consider the increase in production efficiency over time and the resulting savings potential. It is for this reason that we did not hesitate to choose Walter Prototyp tap products.†Li Nan said, “Walter will help us calculate production costs, including tool costs, processing time costs, Labor costs, machine tool costs, etc." Walter Prototyp saves up to 80% of machining time by increasing cutting speeds (such as the use of high-speed cutting series solid carbide tools); up to 10% savings in coolant consumption through MQL (micro-lubrication) By increasing tool life (such as with Paradur HT), tool change saves about 50%; by reducing swarf (such as with Paradur ® Eco Plus), downtime can be reduced by about 50%.
Walter's relevant person in charge said, “Pure tool costs only account for 3% of production costs, while tools have a decisive impact on the remaining 97% of the cost. Walter Prototyp series tap products can significantly reduce processing costs. The increase in cutting parameters brings a huge cost advantage. From this perspective, the price is not only inexpensive but also economical. For a simple example, a 10-yuan tap can process 10 parts while the other The 15 yuan tap product can process 20 parts, I don't think anyone will reject the 15 yuan tap product."
Full value chain service. Walter insists that the company's service consciousness extends from the tool itself to the “whole value chainâ€. The sales and technical service department builds on this idea for all customers from the procurement plan, across the entire production process itself, until the tool is disposed of and recycled. The brand value-added solution ultimately achieves the goal of reducing the production cost of the user by 20% to 50% by the tool that accounts for about 5% of the procurement cost.
Walter offers a comprehensive range of advanced machining processes that not only offer a full range of standard tooling products, but also tailor-made non-standard tooling solutions for customers. Selling a tool or solution to a customer is just the beginning, and the follow-up service is Walter's real advantage. Metalworking is a complex process, with problems such as broken blades, chipping, excessive wear, and blockage of cutting. In many cases, customers can't handle it. At this time, Walter's professional services are needed. Walter has a professional technical team in all major regions of the country to solve customer problems at any time. If it is a general problem, the first-line engineers can solve it at any time; if it encounters a processing problem, it can mobilize the global engineers to solve it together, and can also find a solution from the global shared database. "Walter's after-sales ability is very strong, the database is very powerful, no matter what problems, always help solve quickly." Li Nan said.
China's wind power industry is developing rapidly, and the demand for wind power equipment is increasing. With the development of technology, the processing difficulty and requirements of parts and components have also been continuously improved. This is a big challenge for Chinese wind power companies. The development of China's wind power industry is relatively late, and the company has less experience in equipment processing. In terms of processing efficiency and processing solutions, Walter will use its own expertise and advantages to help China build!
