14.5 TUTORIAL - EMCO MAIER PCTURN 50 LATHE (OLD)

•The lathe is shipped with software that is meant to emulate shop floor interfaces. We don’t have the standard keyboard, so we need to use special key stroke sequences on the PC keyboard.

•Procedure:

1.Connect the air supply to the lathe and make sure that the regulator on the lathe is between 25 and 75 psi - 50 psi is good. Ensure that the lath is connected to the PC with the DNC cable. The computer card must also have a terminator on the second connector - this is an empty connector. Turn on the lathe, and the PC.

2.Once the PC is booted, run the emco control software. The screen may come up with warnings. If these warnings don’t disappear when you hit ‘ESC’ call the instructor.

3.First we must zero the lathe. To do this first hit ‘F1’ and then ‘F7?-ZRN’. A small label ‘ZRN’ should appear near the bottom of the screen. Press ‘4’ on the number pad of the keyboard - the lathe should move in the ‘x’ direction. Next, press ‘8’ on the keyboard, the lathe should move in the ‘z’ direction. After all motion has stopped the lathe is calibrated, and it will be put in jog mode.

4.You can move the lathe with the keys on the number pad as well as perform other function.

4 - move carriage left

6 - move carriage right

2 - cross slide out

8 - move cross slide in <SFT>7 - turn spindle on <SFT>6 - turn spindle off

<SFT>2 - turn on/off chip blower <SFT>1 - turn tool turret

+/- - increase/decrease feed

5.You can now put the mill in MDI mode by pressing ‘F1’ then ‘F6?-MDI’. Push the door open and hold it for a second, it will then stay open. Clear the error on the screen with ‘ESC’ and press <SFT>~ the chuck should open and close. Mount a work piece and then close the door.
