Recently, Mingbai Machinery Tool Technology Co., Ltd. announced that its ultra‑precision 5‑axis simultaneous CNC grinding machine cluster, representing an investment of nearly ten million yuan, has completed all commissioning and officially entered large‑scale production. This marks a significant leap in the company's manufacturing capabilities for precision slitter shear blades, alloy blades, stainless steel blades, and high‑precision circular knives – from "standalone precision machining" to "flexible intelligent manufacturing." Annual production capacity is expected to increase by more than 40%, providing a strong capacity guarantee to meet the continuously growing domestic and international order demand.   Equipment Cluster: The Perfect Combination of High Precision and High Efficiency   The newly operational 5‑axis simultaneous grinding machine cluster consists of five next‑generation ultra‑precision grinding machines, featuring nanometer‑scale linear encoder feedback, on‑line measurement and automatic compensation, and high‑speed, high‑precision synchronous control. These enable single‑setup, five‑face machining of complex‑profile blades, completely eliminating cumulative errors associated with multiple setups in traditional processes. Taking the complex tooth profile machining of slitter shear blades as an example, the new production line reduces single‑piece machining time by 35% compared to previous equipment, consistently maintains profile accuracy within ±0.002mm, and achieves surface finish below Ra0.05μm, fully meeting the increasingly stringent requirements of high‑end customers for blade precision and surface quality.     Flexible Manufacturing: From "Dedicated Machines" to "Quick Changeover"   The new production line is equipped with intelligent production scheduling software and an automatic tool changing system, giving the line a high degree of flexible manufacturing capability. Previously, switching from circular knives to custom‑shaped slitter shear blades required several hours of manual setup and adjustment. Now, with preset machining programs and an automatic tool changer, changeover time is reduced to less than 15 minutes. This capability provides Mingbai with great flexibility in handling multi‑variety, small‑batch custom blade orders, making "customized products with mass‑production efficiency" a reality.   Intelligent Control: Giving Every Blade a Digital Identity   The new production line is equipped with a Manufacturing Execution System (MES) , enabling full‑process data collection and traceability from raw material loading to finished product off‑loading. During machining, grinding parameters, inspection data, operator information, and other details are automatically recorded and stored in a database, creating a complete digital file for each blade. When the product is delivered to the customer, all manufacturing data can be retrieved using a unique traceability code, truly achieving "quality backed by data" and giving customers peace of mind. This feature has been highly praised during recent customer audits and has become a new highlight of Mingbai's quality management.   Significant Results from Production Line Upgrade   According to statistics from the production department, in the month since the 5‑axis simultaneous production line became fully operational, the monthly production capacity for core product lines has increased by 42%, the first‑pass yield has risen to 99.8%, and on‑time delivery rate has reached 100%. In particular, the ability to respond to urgent orders has been significantly enhanced, with delivery lead time for rush orders shortened by 5 days. The production manager said, "The new production line not only allows us to produce faster, but also to produce more precisely. We are confident that we can handle the upcoming peak order season in the second half of the year while maintaining quality."   Continuous Upgrading, Setting a New Benchmark in Precision Manufacturing   The company's general manager said on the occasion of the full production launch, "The full operation of the 5‑axis simultaneous production line is an important milestone in Mingbai's development history. In the future, Mingbai will continue to increase investment in intelligent manufacturing and high‑end equipment, using more precise machinery, smarter management, and more efficient delivery to create greater value for customers and set a new benchmark for China's precision blade manufacturing."

Recently, the R&D center of Mingbai Machinery Tool Technology Co., Ltd. announced a significant technological breakthrough. After nearly seven months of joint research with a well‑known domestic research institution, the company has successfully developed a new "CrAlN/TiSiN/AlCrTiSiON gradient multi‑layer composite coating" technology, which has been stably applied to core products including slitter shear blades, alloy blades, stainless steel blades, and circular knives. Tested by the National Cutting Tool Quality Supervision and Inspection Center and verified by multiple customers on‑site, blades coated with this new coating demonstrate a service life increase of over 150% compared to traditional coated blades under high‑speed dry cutting conditions, while cut surface quality is improved by more than 40%. This marks Mingbai's entry into the industry's leading ranks in tool coating technology.   Targeting Industry Pain Points: The Urgent Need to Overcome High‑Temperature Oxidation and Coating Peeling   Under high‑speed, heavy‑load conditions such as metal rolling and precision slitting, the working surface temperature of blades can reach 800‑1000°C. Traditional TiAlN, CrAlSiN, and other coatings face severe oxidation wear and interface failure under long‑term high‑temperature friction. Coating peeling and hardness degradation lead to a sharp drop in blade life, and frequent blade changes seriously affect production efficiency and machining quality. After conducting in‑depth research at multiple steel processing and new energy material slitting enterprises, the Mingbai R&D team officially initiated the project at the end of 2025, determined to overcome this core technical bottleneck restricting blade life.     Gradient Multi‑Layer Design: From "Single Protection" to "Synergistic Enhancement"   Moving beyond traditional single‑layer or double‑layer coating design concepts, the R&D team innovatively proposed a technical route of "gradient transition + multi‑layer composite + pre‑oxidized protection." The coating structure from inside to outside consists of four layers. The bottom layer is CrAlN (chromium aluminum nitride), which provides strong adhesion to the steel substrate and a firm anchoring foundation. The intermediate layer is TiSiN (titanium silicon nitride), which offers high hardness and good thermal stability. The top layer is AlCrTiSiON (aluminum chromium titanium silicon oxynitride), which forms a dense oxide protective layer in situ on the coating surface through pre‑oxidation treatment, significantly enhancing the structural stability of the coating under high‑temperature oxidation environments. Nano‑scale gradient transition layers are set between each layer, with a total coating thickness controlled at 3‑5μm, effectively eliminating interlayer stress concentration and eliminating the risk of coating peeling.   Performance Leap: Comprehensive Leadership in Hardness, Temperature Resistance, and Friction Reduction   Testing shows that the new gradient multi‑layer composite coating achieves a hardness of over 3600 HV, an oxidation initiation temperature exceeding 950°C, and a friction coefficient as low as 0.22. In high‑speed dry cutting simulation tests, slitter shear blades coated with the new coating continuously slit 3mm thick stainless steel strip for over 25,000 meters, with edge wear only two‑fifths that of traditional TiAlN coated blades, representing a service life increase of over 150%. Even more encouraging, the cut surface roughness Ra value of the new coated blades is stably controlled at below 0.8μm, and burr height is reduced by 40% compared to traditional coated blades, achieving a leap forward in cutting quality.   Positive Customer Feedback, Mass Adoption Imminent   Currently, the new coating technology has been applied to multiple Mingbai core products and delivered to six customers for on‑machine testing. The production manager of a stainless steel strip processing enterprise in Jiangsu reported, "Mingbai's new coated blades ran continuously for five days and the cutting edges remained in good condition. The blade change frequency dropped from twice a day to once every two days, and the overall cost reduction is very significant." A new energy enterprise in Zhejiang stated that the new coated blades exceeded expectations when slitting high‑strength silicon steel and have decided to include Mingbai's coated blades in their annual procurement list.   Breaking Import Dependence, A Key Step in Coating Self‑Sufficiency   Previously, the coating process for some of Mingbai's high‑end blades required outsourcing, which not only incurred high costs but also made delivery times dependent on external suppliers. The successful development of the new gradient multi‑layer composite coating technology and the introduction of in‑house coating equipment have enabled the company to achieve self‑sufficient production of high‑end coating processes. According to estimates, in‑house coating can reduce the overall blade cost by approximately 25% and shorten delivery lead times by 5‑7 days. The company's technical head said, "Coating self‑sufficiency is a key step for Mingbai to improve its industrial chain and enhance core competitiveness. We will continue to deepen our work in the coating field, developing specialized coating solutions for different working conditions."   Continuous Innovation, Leading New Directions in Coating Technology   The company's R&D director said, "The successful development of the gradient multi‑layer composite coating is the result of Mingbai's long‑term accumulation in surface engineering. We will continue to deepen our research on coating processes, explore more new coating materials and structural designs, and continuously provide customers with products that offer longer life and lower cost." The company's general manager also emphasized that Mingbai will continue to invest more than 8% of annual sales revenue into R&D, driving high‑quality enterprise development through sustained technological innovation.

Recently, the R&D center of Mingbai Machinery Tool Technology Co., Ltd. reported good news: after nearly six months of continuous efforts by the technical team, an ultra‑thin high‑precision stainless steel slitting circular knife with a thickness of only 0.08mm has successfully passed internal testing and has been delivered to three precision electronics and medical device enterprises for on‑machine trials. The launch of this new product marks a significant step forward for Mingbai in the field of ultra‑thin precision circular knife R&D and manufacturing, and lays a solid technical foundation for the company's expansion into the precision slitting markets of high‑end electronic materials, medical thin‑walled tubing, and other sectors.     Targeting New Demands in Precision Manufacturing, Solving Ultra‑Thin Slitting Challenges   With the rapid development of consumer electronics, medical devices, precision instruments, and other industries, the demand for slitting ultra‑thin stainless steel strips, precision tubing, and flexible circuit board substrates is growing rapidly. These materials place extremely high demands on knife thickness, precision, cutting edge sharpness, and durability. If the knife is too thick, it causes large slitting losses and material waste; if it is too thin, it lacks rigidity and is prone to deformation and fracture. Mainstream ultra‑thin circular knives on the market typically have a thickness of 0.15mm or more, making it difficult to meet the ultimate slitting requirements of high‑value‑added materials. The Mingbai R&D team formally initiated the project at the beginning of this year, determined to break through the manufacturing bottleneck of ultra‑thin knives below 0.1mm.   Multiple Technical Breakthroughs Achieving the 0.08mm Thickness Limit   The difficulty in manufacturing ultra‑thin circular knives lies in maintaining high hardness, good toughness, excellent flatness, and consistent edge quality at an extremely thin thickness. The R&D team achieved technical breakthroughs in three areas. The first is material innovation, using ultra‑fine grain high‑nitrogen stainless steel as the substrate, with a grain size grade of 13 or higher, combining high hardness (≥58 HRC) with good corrosion resistance, eliminating the need for coating in clean environment slitting applications. The second is the precision grinding process. By optimizing the grinding parameters and grinding wheel selection of the ultra‑precision CNC grinder, and adopting a double‑side alternating grinding + stress relief process, the team achieved stable processing of 0.08mm thick blades, with thickness tolerance controlled within ±0.0015mm and flatness better than 0.002mm. The third is internal stress elimination. Through multi‑step stress‑relief tempering and precision leveling treatment, internal stress in the ultra‑thin blade was effectively eliminated, ensuring no deformation or warping during use.   Excellent Test Data, Performance Comparable to World‑Class Standards   In internal simulation tests, the new ultra‑thin stainless steel circular knife was used to continuously slit 0.05mm thick stainless steel foil strip for over 30,000 meters. After operation, there was no visible edge wear, the cut edge burr height was less than 2μm, the blade flatness remained within 0.002mm, and the thickness deviation did not exceed ±0.0015mm. In extreme bending tests, the 0.08mm thick blade could withstand elastic bending of approximately 20 degrees without plastic deformation or fracture, demonstrating an excellent balance of rigidity and toughness. Evaluated by a third‑party testing institution, the overall performance of this product has reached the advanced level of similar imported products.   Customer Trials with Encouraging Feedback   Currently, the ultra‑thin circular knife has been delivered to three precision electronic material enterprises and one medical device company for on‑machine testing. Among them, the technical manager of a precision stainless steel strip slitting company commented, "Mingbai's 0.08mm ultra‑thin knife is amazing! Previously, the thinnest imported knife we could get was only 0.12mm, and we couldn't reduce slitting losses. Mingbai's knife is not only thinner but also more precise. It has run stably for two consecutive days, fully meeting our quality requirements. We will fully switch over to it for our new production lines." Another medical thin‑walled tubing processing company said that the smoothness of the cut surface exceeded their expectations, saving significant time in the subsequent polishing process.   Broad Market Prospects, Ready for Import Substitution   With the rapid development of domestic high‑end manufacturing, the market demand for ultra‑thin precision knives continues to grow. For a long time, such products have mainly relied on imports from Japan and Germany, which are expensive and have long delivery lead times, becoming a bottleneck restricting the development of related domestic industries. The successful development of Mingbai's ultra‑thin stainless steel circular knife provides customers with a more economical and faster domestic alternative, offering broad market prospects.   Continuous Innovation, Never Stopping   The company's R&D director said, "The 0.08mm thickness is not just a number; it is a breakthrough in the boundaries of Mingbai's capabilities in precision manufacturing. We will continue to deepen our work in the material system and manufacturing processes of ultra‑thin knives, with the goal of breaking the 0.05mm thickness limit within this year, providing customers with even more competitive products." The company's general manager also emphasized that Mingbai will continue to be driven by customer needs and technological innovation, constantly expanding product boundaries and contributing to the advancement of China's precision manufacturing to higher levels.
