铸铁T型槽装配平台工作面通常应采用刮削工艺。对采用刮削加工的3级T型槽平台工作面，其表面粗糙度Ra的最大允许值为5um。铸铁T型槽焊接平台应采用优质细密的灰口铸铁或合金等材料制造，其工作面硬度应达到170-220HB。
铸铁T型槽装配平台在浇注完成后开始用振动清沙和人工除沙并清理铸铁T型槽装配平台毛坯周围的废弃物，清沙完毕后铸件自然放凉并开始第一次回火（时效处理），铸件在回火窑升温至780°并在窑种和窑的温度同时降至50°方可出窑。
在铸铁T型槽装配平台上进行钻孔或是螺纹孔可以用数控龙门铣床进行一次性完成，经过粗加工后用数控龙门铣床进行精加工，数控龙门铣床加工后的精度直线度和平面度每米误差0.008mm，光洁度可以控制在1.2以内经过人工抛光后光洁度最高可以达到0.8。铸铁T型槽装配平台开T型槽必须在刨完平面后放置一天后才能开T型槽或是U型槽、矩型槽等，在粗加工后必须进行第二次回火时效处理，因为第二次的回火时效处理要比第一次重要的多，最多可以释放铸铁平台内部的95%的应力。
Good assembly platform manufacturing
process
The working surface of the cast iron T-slot
assembly platform should normally be scraped. For the working surface of the
3-stage T-groove platform with scraping, the maximum allowable surface
roughness Ra is 5um. The cast iron T-slot welding platform should be made of
high-quality fine gray cast iron or alloy, and its working surface hardness
should reach 170-220HB.
After the casting is completed, the cast
iron T-slot assembly platform starts to use sand for vibration and sand removal
and cleans the waste around the blank of the cast iron T-slot assembly
platform. After the sand is finished, the casting is naturally cooled and
begins to temper for the first time. Treatment), the castings are heated to 780
° in the tempering kiln and the kiln and kiln temperature are simultaneously
reduced to 50 ° to exit the kiln.
Drilling or threading holes on the cast
iron T-slot assembly platform can be completed in one time with a CNC gantry
milling machine. After rough machining, the CNC gantry milling machine is used
for finishing. The precision straightness and flatness of the CNC gantry
milling machine are processed. The meter error is 0.008 mm, and the finish can
be controlled within 1.2. After manual polishing, the finish can reach 0.8. The
T-slot of the cast iron T-slot assembly platform must be placed one day after
the planing plane to open the T-slot or the U-shaped groove, the rectangular
groove, etc. After the roughing, the second tempering treatment must be carried
out because the first The secondary tempering treatment is more important than
the first, and can release up to 95% of the stress inside the cast iron
platform.
