2003 Tool Tech CNC Router Table.
* 24" x 36" working area with 5" of Z axis travel and 6" of gantry clearance. 5' x 5' x 5' footprint.
* 3" x 3" welded steel frame with 2" x 2" welded steel stand.
* Ametek DC servo motors with U.S. Digital encoders on all axes.
* Contoller uses Gecko 320 servo drives and 80 volt dc power supply.
* Limit switches on all three axes and E-stop button on front of frame.
* Nook ballscrews and ball nuts on all axes.
* Thompson linear shafts and bearing blocks on Y axis.
* V ways and bearings on X and Z axes.
* Heavy Duty 1/4" plate steel gantry.
* 3/4" MDF table top and 3/4" birch ply mounting surface with T-tracks.
* Porter Cable 7518 3 1/4 hp. variable speed (10k-22k rpm) router motor.
* Uses Windows based P.C. with Mach 3 or similar controller software (P.C. and software not included).
* This is a heavy duty, well built machine with welded steel table/stand and a heavy steel gantry. It is not a bunch of lightweight, screwed together, aluminum extrusions.
A word about servo motors as opposed to the more common stepper motors: Servo motor systems are referred to as 'closed loop' sytems. The controller is getting constant positional information from the servo motors telling the computer where they are in the process. If something causes the servos to loose steps the computer automatically corrects the problem. This eliminates the possibility of ruining your work piece. Stepper motors are not able to communicate their position to the computer. If a stepper motor looses steps the rest of the cut will be wrong and your work piece will be ruined. Servos are often offered as an upgrade on new routers and can cost thousands of dollars more than the base stepper system. Servo motors are also more efficient and develop their rated power at all speeds. The faster stepper motors are run the lower their power output.
Details and Fine Print. Please Read Carefully!
I had this machine built in 2004. It has had light to moderate use cutting wood. It needs to have the X and Y ball nuts cleaned and reloaded (or replaced). They have crud in them and don't roll smoothly. If you choose to replace the nuts the ball nut model is Nook SBN7500 and they retail for $182 each.
We have purchased a new, larger machine and I don't have time to work on the ball nuts on this one so I'm offering it at a big savings for someone who is willing to do a little work to save big bucks. If you're that person you'll get a great machine at a great price (compare to new machines of this quality that sell for $15,000 or more). All other functions of the machine are in excellent working order.
