The raw material of the firer plate is the high -strength HT200-300,whose surface hardness is of HB170-240,After the two manual handing such as 600℃ to 700℃ artificial annealing as well as 2 to 3 years of natural aging, the T-slot has plate perfectly resists abrasion and has stable precision.there are T-slots on the surface , which can fit the experiment equipment and machine various shape workpiece, such as V-shape, T-shape, U-shape , round holes and rectangle holes.
The direct of using:
1, before using fitter platform, we should use non-corrosive gas to clean the anti-rust oil and wipe clean with a degreasing cotton,
2, measuring temperature changes cause accuracy errors .fitter platform should be located within a range of 20 ± 5 ℃.
3, fitter platform need to be adjusted with the varitation gauge to the right level and ht load on a surface plate is distributed over the working surface.
4, when used carefully and prevent collisions ASAP.
5, If the surface plate is not required for some days, the surface should be coated anhydrous acidic anti-rust oil, moisture-proof paper cover, and putted in a clean dry place.
6, Fitter platform inspection cycle is up to one year.
