Broaching machines are subdivided as follows:

• External and Internal broaching machines (type of the broaching process)
• Horizontal and Vertical broaching machines (location of the main axis)
• Special Purpose broaching machines (chain-type broaching machines and broaching units  for example in transfer lines or combined broaching machines)

Advantages of the vertical design:

• Less floor space required
• No bowing under dead load of the broaching tool
• Better coolant effect
• Proper placement into transfer lines

Advantages of the horizontal design:

• Low overall height
• Larger stroke length
• Single loading of heavy components
• No pit or platform required

Standards:

• DIN 55141: Vertical External Broaching Machines
• DIN 55142: Horizontal External Broaching Machines
• DIN 55143: Vertical Internal Broaching Machines
• DIN 55144: Horizontal Internal Broaching Machines
• DIN 55145: Chain-type Broaching Machines
