PRODUCT DESCRIPTION

Milling is the process of machining using rotary cutters to remove material^[1] by advancing a cutter into a workpiece. This may be done varying direction^[2]on one or several axes, cutter head speed, and pressure.^[3] Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances.

Milling can be done with a wide range of machine tools. The original class of machine tools for milling was the milling machine (often called a mill). After the advent of computer numerical control (CNC) in the 1960s, milling machines evolved into machining centers: milling machines augmented by automatic tool changers, tool magazines or carousels, CNC capability, coolant systems, and enclosures. Milling centers are generally classified as vertical machining centers (VMCs) or horizontal machining centers (HMCs).

The integration of milling into turning environments, and vice versa, began with live tooling for lathes and the occasional use of mills for turning operations. This led to a new class of machine tools, multitasking machines (MTMs), which are purpose-built to facilitate milling and turning within the same work envelope.

• Metal treatment method	Hazards	Precautions
  Electrolytic polishing	Burns and irritation from caustic and corrosive chemicals	Use appropriate personal protective equipment. Install effective exhaust ventilation.
  Electroplating	Exposure to potentially cancer causing chromium and nickel; exposure to cyanides; burns and irritation from caustic and corrosive chemicals; electric shock; the process can be wet, causing slip and fall hazards; potential explosive dust generation; ergonomic hazards	Use appropriate personal protective equipment. Install effective exhaust ventilation, often slotted, push-pull system. Clean up spills immediately. Install non-skid flooring. Use effective design of work procedures and stations to avoid ergonomic stress.
  Enamels and glazing	Physical hazards from grinders, conveyers, mills; burn hazard from high temperature liquids and equipment; exposure to dusts that may cause lung disease	Install proper machine guards, including interlocks. Use appropriate personal protective equipment. Install effective exhaust ventilation to avoid dust exposure. HEPA-filtered equipment may be necessary.
  Etching	Exposure to hydrofluoric acid; burns and irritation from caustic and corrosive chemicals; burn hazard from high temperature liquids and equipment	Implement a programme to avoid exposure to hydrofluoric acid. Use appropriate personal protective equipment. Install effective exhaust ventilation.

  Heat treatment	Burn hazard from high temperature liquids, metals and equipment; burns and irritation from caustic and corrosive chemicals; possible explosive atmospheres of hydrogen; potential exposure to carbon monoxide; potential exposure to cyanides; fire hazard from oil quenching	Use appropriate personal protective equipment. Install effective exhaust ventilation. Display signs warning of high temperature equipment and surfaces. Install systems to monitor the concentration of carbon monoxide. Install adequate fire-suppression systems.
  Metallizing	Burn hazard from high temperature metals and equipment; possible explosive atmospheres of dust, acetylene; zinc metal fume fever	Install adequate fire suppression systems. Properly separate chemicals and gases. Use appropriate personal protective equipment. Install effective exhaust ventilation.
  Phosphating	Burns and irritation from caustic and corrosive chemicals	Use appropriate personal protective equipment. Install effective exhaust ventilation.
  Plastics coating	Exposure to chemical sensitizers	Seek alternatives to sensitizers. Use appropriate personal protective equipment. Install effective exhaust ventilation.
  Priming	Exposure to various solvents which are potentially toxic and flammable, exposure to chemical sensitizers, exposure to potentially carcinogenic chromium	Seek alternatives to sensitizers. Use appropriate personal protective equipment. Install effective exhaust ventilation. Properly separate chemicals/gases.
