Constituents of drilling emulsions and cutting oils can attack certain plastics and damage them irreversibly. It is essential to clean the components carefully after machining, to avoid damage to the plastic due to the effects of cooling lubricants (such as migration, swelling or stress cracking . It is advisable to contact the cooling lubricant manufacturer for information on known incompatibilities with specific plastics. Intermediate tempering is recommended when machining plastics especially for amorphous materials, when high dimensional accuracy is required. Fibre-reinforced or fibre-filled plastics exhibit a higher level of residual stress then unreinforced plastics. Therefore where possible, before drilling, warm the workpiece to approx. 120 °C (approx. 5-6 min / mm cross-section). 70
