Acrylic glass is a material that can be processed in many ways. In addition to milling, laser cutting, drilling, jig sawing, table sawing and hand circular sawing are also possible. Acrylics can also be cut by hand. To do this, they are usually first scored and then cut through.
The most important aspect of cutting acrylic is cooling. If the acrylic cutter gets too hot, the material can melt and cause the cutter head to stick. Therefore, cooling should be used. Minimum quantity lubrication with soapy water is often recommended. Another option is to use compressed air. This variant offers the advantage that the chip spaces are blown free, which prevents clogging. In connection with heat generation, the speed of rotation should also be taken into account. For acrylics, it should be as low as possible. The feed on the other hand should be set higher so that the chip flow is optimal.
Basically, the point is that productivity is increased with the cutting speed. At the same time, the wear of the cutting edges also increases with the cutting speed. It is therefore important to find the optimum balance between cutting speed and wear. The right cutting data play a major role here. Feed rate, rotational speed, speed and infeed must be matched to the material of the workpiece. The next section explains exactly what needs to be taken into account.
The edges are also particularly important when processing acrylic glass. In mechanical processes, they must be repolished in a separate work step in order to develop their full smoothness and brilliance. The more precise the milling process, the less reworking is required afterwards.
