How can spot iron platform Botou Botou cast iron platform platform Advisory: 0317-8336666 phone; overall iron platform specifications 15630717869 maximum of 4 m × 8 m, larger than this size can multi-block splicing, wear after use, can be re-repair scratch restore its resolutions, the coloring method test parts flatness, with accurate, intuitive and convenient advantages. Push on through scraping of cast iron table base plate, the workpiece is relatively smooth, no astringent feeling, to facilitate the measurements, which ensures measurement accuracy. Cast iron platform quality and heat treatment quality of flat performance have a greater impact, or because the residual stress make larger working surface deformation; or because of impatience wear so that the accuracy can not be maintained; or because of lack of small value scraping difficulties roughness. Therefore the use of cast iron plate cast iron materials must be selected, using methods such as aging treatment to eliminate residual stresses of cast iron plate. Cast iron platform parameters: face hardness: hardness HB107-240. After two manual processing (artificial withdrawal length of 600 degrees -700 degrees or natural aging 2--3 years) use precision and stability of the product. Good wear resistance.
