鑄鐵T型槽裝配平臺工作面通常應采用刮削工藝。對采用刮削加工的3級T型槽平臺工作面，其表面粗糙度Ra的最大允許值為5um。鑄鐵T型槽焊接平臺應采用優(yōu)質(zhì)細密的灰口鑄鐵或合金等材料制造，其工作面硬度應達到170-220HB。
鑄鐵T型槽裝配平臺在澆注完成后開始用振動清沙和人工除沙并清理鑄鐵T型槽裝配平臺毛坯周圍的廢棄物，清沙完畢后鑄件自然放涼并開始第一次回火（時效處理），鑄件在回火窯升溫至780°并在窯種和窯的溫度同時降至50°方可出窯。
在鑄鐵T型槽裝配平臺上進行鉆孔或是螺紋孔可以用數(shù)控龍門銑床進行一次性完成，經(jīng)過粗加工后用數(shù)控龍門銑床進行精加工，數(shù)控龍門銑床加工后的精度直線度和平面度每米誤差0.008mm，光潔度可以控制在1.2以內(nèi)經(jīng)過人工拋光后光潔度最高可以達到0.8。鑄鐵T型槽裝配平臺開T型槽必須在刨完平面后放置一天后才能開T型槽或是U型槽、矩型槽等，在粗加工后必須進行第二次回火時效處理，因為第二次的回火時效處理要比第一次重要的多，最多可以釋放鑄鐵平臺內(nèi)部的95%的應力。
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.
