Broaching Machine Design
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
