Precision Meets Performance

The LECO CX300 Series of metallographic sectioning machines, including the manual CX300M, linear feed CX300L, and fully automatic CX300A, are compact benchtop instruments designed to streamline sample preparation with an emphasis on ease of use, laboratory safety, and simple maintenance. Capable of sectioning a broad range of materials for metallographic and materials characterization applications, the CX300 Series delivers efficient and safe operation while helping laboratories save space and improve productivity without sacrificing sectioning capabilities.

Why Choose the LECO CX300 Series

Optimized for Efficiency and Throughput

The CX300 Series features a robust 5 HP motor with intelligent control and a variable-frequency drive for smooth, soft-start operation and consistent cutting speed. Automatic feed options enable unattended and precise cuts while high output cooling minimizes sample deformation. Built for demanding workloads, the CX300 Series delivers reliable performance that keeps operations running efficiently.

Clean, Safe Operation

The CX300 Series is designed for a clean, safe user experience. Its drip-free quarter-circle hood channels fluid away from the workspace while offering clear visibility through a large viewing window and LED-lit chamber. Safety features include an interlocking hood switch and front emergency stop, all built to meet ISO 16089 standards to provide peace of mind and a safe working environment for operators.

Compact, Ergonomic Design

The CX300 Series offers a compact, bench-friendly design—just 28″ wide with a side-mounted power cord for flush wall placement—maximizing lab space without sacrificing cutting capacity. Ergonomic features like a counterbalanced cutting arm and an adjustable touchscreen (CX300A) ensure comfortable, low-effort operation. The layout of controls and easy-access front panel design for all M, L, and A models make these saws intuitive to use and reduce operator fatigue during long cutting sessions.

Easy Maintenance & Reliablity

The CX300 Series is built for durability and easy maintenance. Its corrosion-resistant, one-piece aluminum base eliminates weld points, while a sealed, grease-free spindle requires no daily lubrication. The quarter-circle hood opening allows superior accessibility for operation and maintenance, while the mobile recirculating coolant system with wash-down hose simplifies cleaning. These design choices mean less time spent on maintenance and more time using the saw. Each CX300 is built and tested to LECO’s high quality standards, ensuring consistent performance and a long service life even under heavy use.
