CTM 678-TH

The new Automatic Elbow Machine with Turning Head is designed to produce high quality 90° elbows, without the need for hand turning. This eliminates repetitive motion injuries and reduces operator fatigue.  The cutting plane of this machine is 15° from the horizontal plane, thus requiring 3 cuts for a 90° elbow. Only one operator is required. 
This Machine is equipped with a full set of tooling to produce 6", 7", 8" Ø turned elbows; or tooling can be purchased separately if only 1 or 2 sizes are needed.  Size changes take only 20-25 minutes to complete.

The CTM 345-TH and CTM 916-TH are currently under testing.


The CTM 678-TH has full safety features; including warning labels, an emergency stop button, yellow guards, and a yellow wire mesh safety frame.


Machine cycle time = 22 seconds for all sizes

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

Complete Elbows: 2.5 per minute
150 per hour
1,200 per 8 hour shift
300,000 per year (1 shift/day; 5 days/week; 50 weeks/year)
Assuming labor cost of one operator = $25,000/year, one elbow = 8.3¢ labor to produce
