Strategies to reduce the cost of ball screws under the premise of guaranteeing performance

In the context of white-hot competition in the manufacturing industry, enterprises need to guarantee the high performance of ball screws, but also need to strictly control the cost. This requires the optimization of the whole process from raw material procurement, manufacturing, supply chain management to after-sales service, through technological innovation and management upgrading, to achieve the dual objectives of cost reduction and quality improvement.

I. Raw Material Procurement: Optimizing Material Selection and Supply Mode

(A) Diversified Material Selection and Material Substitution

In terms of material selection, enterprises can explore diversified options. For high-end products with very high precision requirements, continue to use high-quality alloy materials; but under the premise of meeting the performance requirements, try to replace some of the imported materials with new domestic steel. For example, some domestic enterprises to develop high-strength, high wear-resistant alloy steel, performance has been close to the level of imported materials, and the price is more advantageous. At the same time, actively focus on the research and development results of new materials, such as carbon fiber reinforced composite materials, which has high strength, low density characteristics, the future may be in some lightweight application scenarios to replace the traditional metal materials, reduce costs while improving product performance. (ii) Optimize procurement strategy

Establish long-term strategic cooperative relationships with suppliers, and lock the price of raw materials by signing long-term agreements to reduce the risk of price fluctuations. Enterprises can also join other enterprises with similar procurement needs, centralized purchasing, and enhance bargaining power. For example, a number of small and medium-sized ball screw manufacturers jointly set up a purchasing alliance, the common procurement of raw materials to the steel supplier, you can get a bigger discount, effectively reducing procurement costs. In addition, the establishment of raw material price monitoring mechanism, real-time tracking of market dynamics, in the price of low appropriate increase in inventory, reduce the cost pressure brought about by high procurement .

Second, manufacturing: process innovation and scale optimization

(a) Improvement of processing technology

Research and development and application of advanced processing technology is the key to cost reduction. For example, the use of high-speed dry cutting technology to process the ball screw spiral groove can reduce the use of cutting fluid, reduce the cost of cutting fluid procurement and processing, while improving processing efficiency. The introduction of automated processing equipment, such as intelligent CNC machine tools, realizes high-precision and high-efficiency processing through programming, reduces manual intervention, and lowers labor costs and scrap rates. In addition, optimize and improve the existing process, simulate the machining process through process simulation technology, discover and solve potential problems in advance, optimize the machining parameters, improve the material utilization rate and reduce the waste of raw materials . (B) Promote standardization and large-scale production

Formulate the standardization system of ball screw products, and carry out unified design and production of commonly used specifications. Through large-scale production, reduce the fixed cost per unit of product sharing, such as equipment depreciation, management costs, etc.. At the same time, the establishment of modular production mode, different specifications of ball screws can share some parts and production process, reduce production preparation time and cost. For example, the nut, screw, ball and other components of the ball screw modular design, according to customer demand for rapid combination of different specifications of the product, not only to improve production efficiency, but also reduce production costs .

Supply chain and after-sales service: synergy and service optimization

(I) Optimize supply chain management

Integrate the resources of parts and components suppliers, and select suppliers with similar geographic location and strong supply capacity to establish close cooperation, so as to reduce transportation costs and logistics time. Introduce supply chain management system to realize real-time monitoring and management of inventory, procurement, production, sales and other links, optimize inventory level through data analysis, and avoid backlog or out-of-stock raw materials. For example, the use of supplier management inventory (VMI) mode, the supplier is responsible for the management of enterprise inventory, timely replenishment according to enterprise production demand, reduce enterprise inventory management costs . (ii) Innovative after-sales service model

Using IoT and big data technology, install sensors for ball screw products to realize remote real-time monitoring of equipment operation status. Through data analysis to predict failures in advance, preventive maintenance, reduce the maintenance costs and downtime losses caused by sudden failures. At the same time, the establishment of online after-sales service platform to provide customers with remote technical support, fault diagnosis and maintenance guidance to reduce the cost of technician travel. For common failures, we provide standardized maintenance solutions and video tutorials to guide customers to solve problems on their own, which improves service efficiency and reduces after-sales service costs.
