Machine tools, often referred to as the "mother machines" of industry, are essential in the manufacturing process. They can shape, size, and refine the surface quality of raw materials or workpieces made from metal or other materials. CNC (Computer Numerical Control) machines take this process to the next level by utilizing digital information to control the machine’s movements and operations. As highly efficient, precise, flexible, and automated mechatronic systems, CNC machines have revolutionized manufacturing.
High-end precision machining tools currently dominating the market include four-axis or more advanced machining centers, CNC lathes with power turrets, mill-turn composite CNC machines, and machines capable of achieving precision at the ultra-precision level. Leichman has consistently improved its technical capabilities, gradually entering the market for five-axis machining centers. Initially serving the aerospace industry, Leichman’s five-axis CNC machines have expanded into the industrial sector. By 2024, industrial applications account for approximately 30-40% of revenue from new orders, with over 70% of units sold catering to industrial needs.
Enhancing Precision and Stability: Stepping Towards Intelligent CNC Machines
Achieving breakthroughs in high-end CNC machines hinges on improving precision. The accuracy and reliability of upstream core components significantly impact machine performance. Key components of CNC machines include the CNC system, encoders, linear scales, ball screws, spindles, guide rails, and rotary tables.
Leichman’s head of technology, Bruce, highlighted that software limitations pose a major challenge. These include inadequate error compensation in CNC systems and insufficient acceleration and deceleration control precision in servo systems. Enhancements in product accuracy, maturity, and stability require ongoing validation through application.
As the "brain" of a CNC machine, the CNC system typically accounts for about 20% of the total cost. Leichman leverages high-end domestic CNC systems equipped with five-axis linkage technology, such as those from FANUC, Siemens, and Heidenhain. These systems meet critical performance benchmarks like multi-channel operations and multi-linkage capabilities. Independent third-party testing shows that Leichman’s standard CNC system achieves a 100% functional match across over 600 features, while its advanced systems achieve over 98% compatibility across 1,900+ features.
“The higher the technological tier, the lower the generalization level of CNC machines. High-end CNC machines are often customized for specific industries, requiring not just the machine but tailored solutions,” Bruce explained. He added that advancements in CNC systems, core components, and even upstream software like CAD systems are critical to driving future innovations in high-end CNC machining.
Machine stability, a complex engineering challenge, involves factors such as raw materials, design, assembly, maintenance, and overall lifecycle management. To address this, Leichman has implemented technologies like machine compensation and environmental stability controls while standardizing maintenance protocols to ensure long-term operational reliability.
Many CNC machines and systems still require skilled operators to achieve high-precision results, demanding extensive expertise. Looking forward, Leichman aims to integrate AI to transform engineering expertise into machine capabilities. By enabling CNC systems to learn and self-optimize based on production outcomes, the company plans to create intelligent machines capable of iterative improvement and enhanced production efficiency.
Comprehensive After-Sales Service: Addressing Customer Concerns
Four-axis or more advanced machining centers significantly reduce errors caused by multiple clamping operations, improving machining accuracy. While precision and stability are critical for high-end CNC machines, software and service also play pivotal roles. Leichman’s success stems from its dedication to continuous software optimization and robust after-sales service.
Understanding that customers’ precision requirements and production demands vary, Leichman offers tailored solutions. As a global company, Leichman provides swift, convenient, and effective responses across its pre-sales, in-sales, and after-sales service systems.
With customers distributed worldwide, localized manufacturing facilities are a high priority to deliver faster and more convenient support. Over the years, Leichman has actively expanded its global production capacity. The company has established offices in the United States and other regions, forming a comprehensive global production and service network. This proximity enables Leichman to address customer needs quickly and efficiently, alleviating concerns about maintenance and repairs.
Looking ahead, the company plans to enhance the production capabilities and service offerings of its subsidiaries based on market dynamics, further strengthening its position as a leader in the CNC manufacturing industry.
