NANTONG LUCUBRATE MACHINERY TECHNICAL LTDA.

Com a nossa tecnologia, você pode alcançar níveis de produtividade e qualidade sem precedentes. Para saber mais sobre nossa abordagem técnica e como podemos otimizar sua aplicação específica, convidamos você a baixar nosso abrangente white paper, "A Ciência do Entalhe de Alta Velocidade", ou a entrar em contato diretamente com nossos engenheiros de vendas. Deixe-nos ajudá-lo a transformar o gargalo do seu processo de entalhe em uma vantagem competitiva.NANTONG LUCUBRATE MACHINERY TECHNICAL LTD. utilizes a proprietary edge honing process that creates a controlled micro-geometry, reducing stress concentrations and promoting clean shearing rather than tearing. The rake and clearance angles are optimized for specific materials—for instance, a steeper rake angle for stainless steel to reduce work hardening, and a larger clearance for aluminum to prevent built-up edge. Additionally, we apply a polished surface finish to the flute and face, reducing friction and material adhesion. In field tests, these modifications have reduced burr height by up to 70%, eliminating the need for secondary deburring in many cases.

Solution 3: Rigid Tool Design and Precision Manufacturing

To eliminate deflection, our notching tools feature a robust, monolithic design where possible, with thick cores and minimal overhang. For complex geometries, we use finite element analysis (FEA) to simulate high-speed loading and optimize the tool body for maximum stiffness. The tool holders are machined to sub-micron tolerances and feature high-precision collets or shrink-fit interfaces to ensure concentricity. Furthermore, we incorporate internal cooling channels that deliver coolant directly to the cutting edge, further reducing thermal deflection. The outcome is consistent part quality with tolerances held to ±0.005 mm, even at high speeds.

Customer Case 1: Automotive Stampings in Germany

Schmidt Metalltechnik, a Tier 1 automotive supplier in Stuttgart, Germany, was struggling with excessive tool wear on a high-speed line producing transmission plates. The notching tools were failing every 15,000 strokes, causing 2 hours of downtime per shift. After switching to NANTONG LUCUBRATE MACHINERY TECHNICAL LTD.'s carbide notching tools with AlCrN coating, tool life increased to 75,000 strokes. “The improvement was immediate,” says Klaus Richter, Production Manager. “We reduced tool changes by 80% and our scrap rate dropped from 5% to 0.5%.”

Customer Case 2: Electrical Steel Laminations in the USA

Precision Motors Inc. in Cleveland, Ohio, produces laminations for electric vehicle motors. Burrs on the notched edges were causing short circuits and costly rework. They implemented our PCD-tipped notching tools with optimized edge geometry. Burr height was reduced from 50 µm to less than 10 µm, eliminating deburring entirely. “We now run 30% faster with zero burr-related defects,” reports Sarah Thompson, Manufacturing Engineer. “The payback period was under three months.”

Customer Case 3: HVAC Components in Italy

ClimaTech S.r.l. in Milan, Italy, manufactures heat exchanger plates. High-speed notching of aluminum was causing frequent tool breakage and poor edge quality. Our PM-HSS tools with polished flutes and ZrN coating solved the problem. Tool life tripled, and edge quality improved so much that leak rates in the assembled units dropped by 60%. “We’ve partnered with NANTONG LUCUBRATE for five years, and their tools are the most reliable we’ve used,” says Marco Bianchi, Operations Director.

Customer Case 4: Aerospace Brackets in Canada

AeroStruct Dynamics in Montreal, Canada, notches titanium brackets for aircraft. The high-speed process was causing rapid tool wear and dimensional drift. Our solid carbide tools with TiAlN coating and internal cooling increased tool life from 200 to 1,200 parts per tool. “The consistency is remarkable,” says Jean-Luc Picard, Lead Machinist. “We no longer have to inspect every part—the process is that stable.”
