Cast Iron Straightedge

Cast iron straightedges are primarily used for inspecting right angles and marking lines on workpieces,as well as checking the perpendicularity of relevant surfaces on parts or components during equipment installation,adjustment,and repair.

Cast iron straight edges are suitable for perpendicularity inspection of machine tools,mechanical equipment,and components,as well as installation positioning,machining alignment,and marking.They serve as essential measuring tools in the mechanical industry,characterized by excellent stability and ease of maintenance.

Cast iron straight edges are mainly employed for inspecting right angles and marking lines on workpieces,as well as verifying the perpendicularity of related surfaces on parts or components during equipment installation and maintenance.They are also used for installation positioning,machining alignment,and marking,making them indispensable measuring tools in the mechanical industry.Their advantages include suitable precision,stable performance,cost-effectiveness,and ease of maintenance.

Cast iron straight edges are resistant to deformation,portable for storage,and convenient to use.For long-term storage,a thin layer of general industrial oil can be lightly applied to prevent rust,ensuring easy preservation.The triangular hollow design and flat profile allow the straight edge to be hung for convenient storage.

During measurement,attention should be paid to the placement of the straight edge to avoid tilting.It should be positioned perpendicular to the intersecting line of the two surfaces forming the right angle,meaning it must be firmly and vertically pressed against the workpiece.Otherwise,measurement errors may occur.Before use,the working surface of the cast iron straight edge and the surface to be inspected must be cleaned to ensure flatness,preventing damage to the straight edge or compromising measurement accuracy.

Before use,the cast iron straight edge must be installed and calibrated by qualified personnel.Using a straight edge without proper installation and calibration is meaningless and may lead to structural damage or deformation,rendering it unusable.Installation and calibration by unqualified personnel is a violation of operational procedures and is strictly prohibited.
