Embodiment 1
[0032] The preparation process of the sapphire camera window of the present embodiment includes the following steps:
[0033] Step 1, crystal rod extraction; take the sapphire crystal of A direction, M direction or C direction, and then use the rod removal machine to remove the rod, so as to obtain the crystal rod;
[0034] Step 2, crystal cutting: use diamond wire cutting equipment to cut the ingot, so as to obtain the wafer;
[0035] Step 3, grinding; use a grinding machine to grind the wafer; when grinding, add grinding liquid, the grinding disc pressurizes the wafer to 0.022Mpa, and the speed of the grinding disc is 1200r / min; after the grinding is completed, clean it with absolute ethanol; The grinding liquid components include: 2% cubic boron nitride powder with a particle size of 20 μm, 16% alkylphenol polyoxyethylene ether, 6% glycerin, 11% polypropylene glycol 400, and the rest is deionized water;
[0036] Step 4, chamfering; use the diamond grinding wheel of the num...
Embodiment 2
[0044] The preparation process of the sapphire camera window of the present embodiment includes the following steps:
[0045] Step 1. Crystal ingot; take the sapphire crystal in A-direction, M-direction or C-direction, and then use the rod-removing machine to remove the rod, so as to obtain the crystal rod;
[0046] Step 2, crystal cutting; using diamond wire cutting equipment to cut the ingot to obtain wafers;
[0047] Step 3, grinding; use a grinding machine to grind the wafer; when grinding, add grinding liquid, the grinding disc pressurizes the wafer to 0.02Mpa, and the speed of the grinding disc is 1000r / min; after the grinding is completed, clean it with absolute ethanol; The grinding liquid components include: 0.5% cubic boron nitride powder with a particle size of 10 μm, 14% alkylphenol polyoxyethylene ether, 4% glycerin, 9% polypropylene glycol 400, and the rest is deionized water;
[0048] Step 4, chamfering; using a diamond grinding wheel of a numerically controlle...
