Question:

How much is the flatness of the 1200*1200*15 aluminum sheet?

How does 1200X1200X15 6061 aluminum, CNC processing, the plane degree can reach the number of my clients to 0.2, but I used to use the MS 1000X1500X70 to the material processing, the flatness is only 1, please experienced friend to help, thank you

Answer:

The first rough machining, no precision position of the first place, finishing allowance for heat treatment of unilateral 0.15MM, and then remove the stress of 420 degrees Celsius for 4 hours, with the furnace cooling (very important), doing fine processing, can guarantee within 0.03.Is the aluminum plate with a thickness of more than 0.2mm to 500mm, 200mm width, length less than 16m aluminum material called aluminum plate or aluminum sheet, aluminum is below 0.2mm, 200mm within the width of the row material or bar (of course, with the progress of the large equipment, the width can be 600mm row material also more). Aluminum sheet refers to the rectangular plate made of aluminium ingot rolled and divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, middle thick aluminum plate and pattern aluminum plate.
Buy aluminum plate before processing, we must plastic, rolling. Processing should leave margin, release the stress, no precision requirements of the hole to do first, after the two plastic. In the semi gold processing, plastic grinding before finishing. We do that every big 700*700*12, and do the flatness down 0.03-005.
The first rough machining, no precision position of the first place, finishing allowance for heat treatment of unilateral 0.15MM, and then remove the stress of 420 degrees Celsius for 4 hours, with the furnace cooling (very important), doing fine processing, can guarantee within 0.03
