[Emc-users] Lathe Tool-Changer

2011-06-16 Thread Clint Washburn
I am in the process of setting up classic-ladder for the tool-changer on my Hitachi-Seiki NH500 Turret lathe. I am using a mesa 5i20 card for inputs and opto22 relays. For each tool position it uses a combination of inputs from six switches that follow 6 cams on a drum to dictate position

If I understand correctly, what You mean by the cutting above or below centerline, then Dave's sketch shows that it is inevitable anyway. If the code after offsetting is correct for producing required profile while in Decart's coordinates, then it will be correct also in polar coordinates. I

Clint - my Tsugami lathe is similar, except it had a 3phase AC motor with hi and lo gearing for rotation - but did include the binary cams (position, top-dead center and a PARITY bit!) - although that setup did prove to be less-than-optimal in the long run (I have since converted the turret

[Emc-users] Linear Servo Motors

Has anyone found a source of less expensive linear servo motors? I have a client who really wants to use some linear servo motors to retrofit some machines. He doesn't really need them but he has some Parker linear servo motors that I installed a couple of years ago and he really likes them

This is the tool change component I use for the tool changer on my Enshu 3 axis mill. This mill has a chain matrix on the side of the machine, a random tool changer and a swing arm to change the tool in the spindle with the tool in the tool change pot use, copy, modify at your pleasure
