Summary
The use of hydraulic workholding for machining yields large paybacks, even for modest size production runs, in particular due to reduction of up to 20:1 in setup time.

Several important concepts occur in three’s:

Three Elements of a workholding system

• cylinder
• pumps
• control devices

Three Functions of cylinders

• positioning
• supporting
• clamping

Three Types of pumps

• Air operated
• Electric operated
• Intensifier (hydraulic operated)
  

Three functions of valves

• Control fluid flow path
• Control fluid flow rate
• Control fluid pressure
