EMCO TM 02 Turning Center
To begin the operation of the red Emco turning center here in our lab at Mt. Hood Community college. First step is to turn the main power on. To do that turn the breaker on, followed by the machine power button. The order in which we do this is extremely important because of the power conversions that take place between the European standard that’s inside the machine tool and the American standard on the main power coming in and it goes through some kind of main power converter. Show us the main toggle again. The main toggle is this one the first one that we do followed by the machine power, now we notice that when the machine power goes on the cooling fans for the electrical components for the machine come on you can hear those running. As we come around to the front of the machine we notice that the work light is on on the inside and we notice that the control has begun it’s initialization process. This error message here is telling me that the emergency stop is on so if I turn that off I not have an alarm telling me that the reference position is not set. That means we need to calibrate this machine tool before we do anything else. I press the clear entry button which is CS on the control, I close the door because this machine requires that the door be cycled, I turn the hydraulics on using the auxiliary mechanism. What you just heard is the auxiliary hydraulics coming on. And now I have highlighted this point on the screen the reference indicator telling me I need to reference the machine, notice there is nothing for the x and z axis at this point this machine will not run until it’s referenced. So I next press the cycle start button if you notice in the slides the door has to be closed the first thing you did is move the x axis a little bit now it’s going to defines the x reference position factory preset it puts the x value crt and now it’s found the z position. At this point we are ready to qualify the tools.
One of the differences between the emco turning center is that the program workface coordinates are set within the cnc code for the particular part that you’re making so we do not have to qualify for a particular axis position. What we do qualify for is the tool length. The steps in qualifying for the tool length are:
first off all I’m going to make sure my turret or my chuck is closed and I got a work piece in here.
I next jog my turret to an empty position and I have 3 tools in here so I’m going to come down to a position like that number seven position which gives me an empty turret position. Now using the jog buttons I’m going to move using the manual jog buttons I’m going to use my override switch set a 100% at this point I can go pretty fast. I’m moving the turret I move it out in z so it clears the tail stock my next step is to manually jog it down in x I get the turret down in x now I’m going to bring it closer to the face of the part. One thing I need to watch with this machine is I have to be very c
