In the acrylic plate drilling operations, priority is recommended to use pointed or flat acrylic special drill bit, the angle is usually designed between 60 ° - 90 °, can greatly reduce the phenomenon of stress concentration.
Before the formal drilling, the use of markers or punches on the surface of the acrylic board clearly and accurately marked out the drilling point, to better help the operator to control the direction of the drill, thereby reducing unnecessary damage to the plate. Afterwards, the acrylic board placed on a smooth worktable, and the use of clamps to fix it firmly, this is also very important, if placed on the table is not smooth, the opening of the holes is easy to rupture. Turn the drill to a low speed, typically 500-1000 revolutions per minute. Drilling at low speeds significantly reduces stress concentrations. At low speeds, it helps to maintain the physical stability of the sheet and reduces the risk of rupture, whereas high speeds increase the probability of rupture. Drill should also be kept perpendicular to the surface of the plate after the completion of drilling, the edge of the hole usually exists some burrs, you can use fine sandpaper or special polishing tools to carefully clean the edge of the hole. In case of acrylic sheet drilling cracks, we need to immediately stop drilling, check whether the drill bit is blunt, whether the speed is too high, timely replacement of sharp drill bits and reduce the speed, based on the degree of cracking to assess whether to continue to drill, and in serious cases, consider replacing the sheet.
When drilling acrylic sheet, different thicknesses of sheet need to be treated differently. 3mm thick acrylic sheet and acrylic sheet 3mm clear need to be more careful. By the way, our 3 mm acrylic sheet price is very favourable, welcome to visit us.
