Machining processes

The manufacturing of engineered products or parts often requires the removal of material and some form of shape changing. This is known as 'secondary machining' or 'forming' Traditional secondary machining processes and the machines that perform them fall into three groups -turning, milling and drilling.

Safety while machining.

The most common causes for accidents while using a secondary processing machine are:

  • Loose clothing snagging on a revolving part
  • Flying pieces of material entering the eye.
  • Hands or arms coming into contact with revolving surfaces/parts.
  • Minor burns from hot material surfaces

You should always follow the correct procedures and wear the right Personal Protective Equipment (PPE) for the process that you are using. Goggles must be worn to protect the eyes, overalls/workshop coat must be worn to protect clothes and skin from hot metal chips and harmful liquids.
