Overview
High-Precision Cast Iron Angle Plate
Engineered from durable HT250 cast iron, this angle plate serves as a critical verification standard for 90° perpendicularity and parallelism. It provides a stable, rigid platform for holding workpieces at precise angles during milling, drilling, and grinding operations. Designed for toolrooms and quality control departments, it ensures exceptional dimensional stability and vibration dampening for high-accuracy machining and inspection tasks.
