Circle T Manufacturing

The Circle-T Lock miter machine is a game changer for the production mill floor. Once the machine was installed and set up everything beyond that is nearly effortless to set up and run. We use it weekly and our production on perfect lock tight corners has elevated because of this machine and we are also able to assemble the components as they are produced.

Circle T lock miter machine has been a great investment. We were spending hours cutting and fitting miter joints. The lock miter from Circle T takes a fraction of the time with better results. The engineering and quality of this machine are very well thought out and put together. Would have no problem purchasing another one.

This machine has filled a need we didn’t know we had. It arrived earlier than anticipated, set up was easy and fine tuning it was a breeze. It has made making wood tops, box shelves, columns and more much quicker to assemble and cuts down on putty and waxing seams. We wax the top everyday due to the high volume of parts run through it but after a month we are still on the same set of knifes. The “A” and “B” switch is an awesome feature.

Circle T’s LM116 machine is an absolute home run! We operate a mid-sized high-end custom cabinet shop and utilize well over a hundred feet of mitered joinery a day. Applications include, finished sides of cabinets, filler-returns, lumber edges on tops and shelfs, etc. We lock-miter everything from hickory lumber to veneer core ply to Medex. For finished sides of face-framed cabinets we run the entire assembled frame right through our LM116 (just be sure to remove screws if you have a narrow stile). For many years we offered a tongue and groove joint as standard for these applications and a simple miter was available as an upcharge. Now the lock-miter is standard. Why not utilize a joint that is both aesthetically and structurally superior while at the same time being just as easy to assemble? The answer to that question is as old the lock-miter joint itself. If one wanted to lock-miter production work there were always two choices, either do shaper setup every time you had to switch between male and female profiles or run two shapers that have to be perfectly in sync with each other. Need a 45 degree or some other oddball joint? Now you have two more shaper setups, four to get back to 90 degrees. Circle T has solved all of this. Male to female and back again is a simple flip of the switch. Different angles are simply dialed in and verified with a digital readout. The build is rock solid, the knives last a long time and are easy to change to anyone familiar with insert tooling. The power feeder is awesome. Customer support is superb. Thank you Circle T for solving the lock-miter dilemma!
