Chip Evacuation

Chip evacuation refers to the process of removing chips that are created during machining processes. Machining processes involve using a cutting tool to remove material from a workpiece. The chips are the unwanted pieces of material that are generated as the tool cuts into the workpiece.

There are several reasons why chip evacuation is important:

  • Improved surface finish: If chips are not properly evacuated, they can build up on the workpiece and interfere with the cutting tool, resulting in a poor surface finish.
  • Reduced tool wear: Chips can also cause wear on the cutting tool, which can shorten the tool's lifespan.
  • Safety: Built-up chips can create a fire hazard or become projectiles if they are not properly evacuated.
  • Cooling: Coolant is often used during machining processes to help cool the workpiece and the cutting tool. Chip evacuation helps to ensure that the coolant can reach the cutting zone and do its job effectively.

There are a number of different methods that can be used for chip evacuation, including:

  • Coolant: Coolant is a liquid that is sprayed onto the workpiece and the cutting tool during machining. The coolant helps to cool the workpiece and the cutting tool, and it also helps to evacuate chips.
  • Chip conveyors: Chip conveyors are mechanical devices that are used to remove chips from the machining area.
  • Air jets: Air jets can be used to blow chips away from the cutting tool.
  • Vacuum systems: Vacuum systems can be used to suck chips away from the cutting tool.

The best method for chip evacuation will depend on the specific machining process being used.
