Cast iron flat feet | cast iron scraping flat feet | test flat feet | measuring cast iron I-shaped ruler 500-6000mm

Parallel feet There are two face, face with scraping process, so that the measurement accuracy is higher, the parallel-foot face can not seriously affect the appearance and performance of the sand holes, pores, cracks, slag, shrinkage, scratches , Bumps, rust spots and other defects, otherwise it will make the measurement distortion.Piping the use of parallel foot detection, by its two face with the level, micrometer and other auxiliary measurements, parallel to the various flat feet to test the uneven and Not straight, check the vertical between the parts can also be used for equipment installation and commissioning.

Parallel feet Check the flatness of the workpiece often use the coloring method and instructions table method to test the workpiece straightness using optical gap method. Parallel feet of the use of temperature (20 ± 5) ℃.

Parallel feet The use of high-quality fine materials such as gray cast iron or alloy cast iron and other materials according to JB / T7977-99 standard manufacturing method of machining and hand-grinding, so that it does not rust, Naisuan Jian, wear resistance, not Magnetization, the same type, etc. Parallel feet can be in a heavy load and a certain temperature to maintain the high precision measurement.
