Cast iron scribing plate
/ = Cast iron platform
Products manufactured according to standards
The products are made into rib plate type and box type working surfaces with rectangular materials
The working surface adopts scraping process working surface It can process
,
,
grooves, round holes, long holes, etc. The cast iron flat plate is a flat reference instrument used for workpiece inspection or marking. The installation of the flat plate should be adjusted to level, and the load should be evenly distributed on each fulcrum. The ambient temperature should avoid vibration during use
= Flatness of the scribed platform
=
/# = Level
:< br/> = Its flatness
(

)= +.(D
= is the diagonal length or diameter of the platform
)
= Used for highly precise measurements
= often used in laboratories.
.
= Grade
:
/# = Its flatness is
= Twice the error of grade
= Commonly used in tool inspection rooms as precision measuring tools For inspection purposes.
.
= Grade
:
/# = Its flatness is
= Four times the error of grade
= Commonly used in tool inspection rooms or on site For inspection measuring tools or marking purposes.
= Marking platform
= The basic production process flow is:
= 1. Marking platform blank: make drawings according to technical requirements, make models according to drawings, ingredients, modeling, drying, The purpose of heat treatment of each part of the casting, sand falling, cleaning and inspection of the blank and the aging treatment of the blank is to reduce the stress inside the casting and prevent deformation after machining.
= 2.
/# = Marking platform
/# = Mechanical processing: appearance inspection and marking, processing and inspection
= 3.
/# = Marking platform
/# = Workpiece leveling, manual scraping and grinding, inspection by the inspection department
= Four,
/# = Marking platform
/# = Appearance treatment, spray painting ,Packaging and storage.
= The accuracy of the marking platform
= It can also be said to be the flatness of the cast iron flat plate: the general accuracy of the cast iron flat plate can be divided into
= grade,
/# = grade,
/> = level,
= level. The accuracy standards of cast iron flat plates can be found in the "Machinery Industry Standards of the People's Republic of China"
=
/# =. The selection of accuracy standards generally depends on the usage conditions.
= Cast iron flat plates with a precision of above grade are generally used for inspection, marking, assembly, etc.
= Cast iron flat plates with a precision of below grade are generally used for riveting and welding.
= scribing plate
(= platform
) = Purpose
=:
= It is a measurement standard for checking the flatness, straightness and other geometric tolerances of machine parts. It can be used for parts marking, grinding, processing, and installation of equipment. It is a measurement benchmark for testing geometric tolerances such as plane, parallelism and straightness of mechanical parts. It can also be used for scribing, riveting, welding and grinding process processing and measurement of general parts and precision parts.
= Scored plate
(= Platform
) = Material
=::
= High-strength cast iron
= Working surface hardness is
= After two manual treatments (artificial annealing
= degree
/# = degree and natural aging
= years), the product has stable precision and good wear resistance.
