Advanced Grinder/Polishers for Fast, Reliable Sample Prep

The LECO PX Series of metallographic grinder/polishers – including the PX300, PX400, and PX500 models—emphasizes ease of use while delivering exceptionally flat specimens that are ideal for microhardness or microstructural analysis. With innovative features like multi-touch controls, automated cleaning functions, and robust design, the PX Series provides an efficient, safe, reliable, and clean solution for a wide range of lab grinding and polishing needs.

Why Choose the LECO PX Series

Optimized Grinding & Polishing Performance

The PX Series is built for efficient, high-quality sample preparation with a durable gear-drive system that eliminates belt maintenance and ensures smooth, stall-free operation under heavy loads. PX400 and PX500 models feature high-torque, VFD-controlled motors for consistent speed and faster, uniform polishing—even with large or multiple samples. Supporting 8″, 10″, and up to 12″ platens (PX500), the series offers flexibility and delivers exceptionally flat, consistent specimens essential for accurate microstructure and hardness analysis.

Ease of Use & Automation

The PX Series prioritizes ease of use with intuitive controls across all models. PX400 and PX500 feature a 7″ touchscreen for quick access to pre-loaded and custom methods, adjustable speeds, and safety features like two-point start and emergency stop. The PX300 offers simple analog controls and an optional foot pedal and manual head with spring-assisted lift—making it accessible for users of any experience level.

Clean, Safe, and Low-Maintenance

The PX Series is designed for cleanliness and safety. A deep, spill-resistant bowl with a spiral drain minimizes splashing, while an automatic bowl wash and spin-dry cycle (PX300/400/500) reduce cleanup and prevent abrasive buildup. Quick-detach water spigots simplify rinsing. Safety features include protective splash guards, LED work lights, emergency stop buttons, and fully enclosed housings that meet CE and international safety standards—ensuring safe, reliable operation in demanding lab environments.
