Four types of fixed-length cutting machine as followings:
| Screw-type fixed-length cutting machine: | High stiffness, impact resistance, with self-locking, cutting at any position and wide applicability. |
| Rack-type fixed-length cutting machine: | Space saving, stiffness, impact resistance, arbitrary position measuring. |
| Pendulum rod fixed-length cutting machine: | Simple structure, impact resistance, arbitrary position measuring machine. |
| Worm gear fixed-length cutting machine: | Simple structure, impact resistance, mechanical locking, fixed position measuring machine. |
