introduction:
the cast iron surface plate is called working platform(working plate),worktable.
the gross structure of cast iron surface plate(worktables)is divide into box type and rib type.
the shapeofworking surface is rectangle, square and roundness. according to the precision 
machining,it’s divided into finish plane and scraping. 
special provision
we provide special tapped holes and t-slots at the top working surface for fixingworkor measuring instruments at extra cost. these are offered as per customers’ specifications. welcome visit our factory and check our cast iron plate.
installationandadjustment
when used surface plate ,youshouldfirst installation debugging,then you can use it . no significance work on surface plate if they aren\'t properly positioned .surface plate should setup on level off, firm without shock place.pleasefirst put the pad iron down ,then put the surface plate on the pad iron ,removal the wooden case and oil . measurement with the levelness of the surface plate ,when the surface plate isn\'tlevel,please adjust the pad iron .( in the process of adjusting attention to safety)
usage
(1) suitable for various inspections and benchmark planes for accuracy measurement.
(2) used widely as the measurement benchmark for machine tool inspection and to inspect the dimension accuracy or running differencewiththe function of performing precise lineation.
(3) it is an essential measuring tool in machine manufacturing.
materialandprocessing
the material is high strength cast iron ht200-400, and the rigidityofworking face reaches hb170-240. it goes through twice of man work processing (man work anneal by 600-700° with natural validity of 2-3 years) in order to make the product stable in accuracy andgoodin grinding resistance.
precision:
it is in accordance with the procedureofstate standard for measurement and inspection, which is divided into four levels of 0-3.
price:
according to your detail requirement.
