CTM 345-456-567-678

The Automatic Elbow Machine is designed to produce high quality straight elbows, which can be hand turned to any angle between 0° and 90°. The cutting plane of these machines is 15° from the horizontal plane, thus requiring 3 cuts for a 90° elbow. Only one operator is required. (see the CTM 916 for larger size elbows) The Elbow Machine is available in any of the 4 size configurations noted above. They are equipped with a full set of tooling to produce the respective 3 sizes of elbows; or tooling can be purchased separately if only 1 or 2 sizes are needed. Size changes take only 15-20 minutes to complete.

Elbow machines have full safety features; including warning labels, an emergency stop button, yellow guards, and a yellow wire mesh safety frame.


Machine cycle time = 20 seconds for all sizes

Load time = 2 seconds (dependent upon speed of operator)

Complete Elbows:
2.7 per minute
164 per hour
1,309 per 8 hour shift
327,000+ per year (1 shift/day; 5 days/week; 50 weeks/year)
Assuming labor cost of one operator = $25,000/year, one elbow = 7.6¢ labor to produce

Note: The CTM 678 is available with a FAST HEAD option, which has a cycle time of 16 seconds
