James I've installed 2 touch carrages. with 2 Victor M300 series machine torches. the master cararrige has a the axis drive motor mounted to it. It has a slave carrage connected to it by an adjustable crossbar. On the second carrage is also mounted a HyperTherm max 200 plasma torch.
To provide position to the Burny 5; I have connected BEI encoders with 1024 count resolution. the 400 watt servo motors drive a 40 to 1 gear reducer turning a 1.5 Dia. Spur gear. My max positioning speed is 235 inches a miniute.
My problem is finding a good way to dump the back pressure that is used to build the cutting/peirce pressure inside the victor Dome Regulator. a small orfice in the line along with a flow control neddle valve sets the perice rate. but when we shift back to prehear gas only, there is still oressure on the control line to the dome regulator.
We copyed the gas system from an old ESAB MCD-10 that we rebuilt years ago. |
