Product Application:
Mainly used as installation and inspection of machine tools,
inspect vertical degree, parallelism and straightness of guides and
precision component in modern industry and scientific research
institutes.
Granite tri square
There are two small side lapped measuring surface.
Feature:
Square gauge include feet ,angle plate and so on (Special tool to
90 degrees). Used to test the verticality of workpiece and
equipment installing. Installation and scribing orientation of
mechanical industry is an important measurement tools. It is
characteristic of high accuracy, good stability, convenient in
maintenance.
Merit ,lossy black ,structure of precision ,homogeneous structure
,high strength ,hardness ,good stablility, no rust, acid-proof
alkali, good wearproof ,magnetization-resisting and high durability
.In general heavy load and high temperatures can maintain high
precision.
Application :
For inspection machine spindle and else squareness of work-pieces.
Have round role for size over 250x160mm to reduce weight so to take
easily.
