The machining of acrylics is very similar to that of soft brass, aluminum and woods. However
- acrylics turns soft when temperature higher than 80℃. Thus adequate cooling during machining acrylics is necessary. To control machining temperature and to remove the scraps, coolant and/or lubricant may be used.
- acrylics is rigid material and somewhat brittle. Thus the feeding speed should not be too high during machining.
- Water spray, cutting lubricant or compressed air are good choice for cooling and/or lubrication during machining acrylics, but do not use solvent tpye cutting lubricant to prevent the effect of solvent etching against acrylics.
- Inadequate machining and cooling will cause inner stress accumulation in acrylics and unexpected craking of acrylic products may eventually happen in daily service. To minimize the risk, annealing following machining of acrylic product could be considerred.
