cast iron T-slot plate
T-slot plate are mainly used
as fitting workpieces. Which is the fadation plate of adjustng, assembling and
reparing equipments.
The raw material of the cast
iron T-slot is the high -strength cast
iron HT200-300 ，whose surface hardness is of
HB170-240.After the two manual handing such as600℃to700℃artificial annealing as well as 2 to 3 years of natural aging, the T-slot has
plate perfectly resists abrasion and has stable precision.
Precision
accuracy:T-slot plates shall be
classified as Grade 0, Grade 1, Grade 2, and Grade 3.
Technical requirements of
T-slot Plate:
1.The working surface, when
inspected visually, shall be free from blowholes, sand holes, cracks, slag
inclusions scratches, porous patches and other visual flaws.
2.The working surface shall
be clean and uniform and the other sides shall be painted well.
3,the plugging of blowholes
or porous patches in the working surface whose accuracy is Grade 0- Grade 3
with material of a similar comPOSTTTION is permitted provided that such a repair
does not affect stability or accuracy.
4,The raw material of Cast
Iron Surface Plate shall be the close-grained cast iron whose hardness is of HB
170~220.
5, the surface plate are
usually adopted the scraping technology.
6, the surface plate after
scraping technology need coloring method for inspection.
