• Introduction
Cast Iron Square Cylinder is the tools to make three-dimensional scribing in industrial production workshop; also can detect parallel and perpendicular to the mechanical parts. It’s top with holder, using for inspection or draw lines at any angle for precision parts. Apply to measuring and engraved mark as a holder.
 
The raw material of the plates is the high-strength cast iron GG20-GG30 (HT200-300). After two times artificial annealing treatment, complete removal of internal stress, show stable casting structure, and not easily deformed
 
The size is according to the customer’s requirements.
