Maximum Precision and Outstanding Surface Finish: Seibu

Modern manufacturing continues to demand higher precision, superior surface finishes, and increased productivity. At the same time, manufacturers must control production costs and minimize scrap rates.

Seibu addresses these challenges with advanced machine technology engineered to deliver maximum accuracy and highly repeatable machining results.

Cross-Table Design for Stable Precision

Seibu’s cross-table design ensures high geometric stability in wire EDM machining. The machine column remains stationary during machining, while the work tank moves. This keeps the upper and lower wire guides in a constant position and maintains stable wire geometry throughout the process.

The highly rigid machine construction and low center of gravity provide consistently high machining accuracy across the entire work envelope. Particularly when producing demanding precision components, this design creates the foundation for repeatable results and reliable wire EDM processes.

URMA Seibu CNC EDM Kisage

Japanese Kisage Hand-Scraping for Long-Term Accuracy

Traditional Japanese Kisage is a precision hand-scraping technique used to finish critical guideways and mating surfaces. It produces highly accurate contact surfaces and allows geometric deviations to be minimized systematically.

Seibu applies this manufacturing method to maintain the machine’s long-term geometric stability. Combined with advanced CNC controls, generator technology, and automation, it creates a wire EDM machine concept engineered for high precision, repeatability, and process stability.
