TRAK 2op Machine Guide

Standard start up procedures for the Southwestern Trak 2nd operation machining center.

 

 

Overview

  • The Trak 2op machine is intended for light to medium size work.
  • The table size is 18”(457 mm) x 15”(381 mm) with machine travel limits as follows: X axis is 14” (355 mm), Y axis is 12”(304 mm), and the Z axis is 17”(431 mm).
  • It has a maximum spindle speed of 6000 rpm and a maximum rapid feed rate of 600 ipm.
  • If you need a machine that is capable of doing larger work, consider using the TMC 7.

TMX controller

The TMX controller has some of the same capabilities as the EMX controller (Eisen mills) and the SMX controller (Trak DPM's).

 

It's capable of programming conversational programs (PT4) along with running GCD files generated from a CAD program and loaded to the machine from a thumb drive.

Machine Start up

1. Turn the Main Power Switch in the back of the machine from the "OFF" position to the "ON" position as shown in the pictures below.

off     on

2. Be sure the red E-Stop button, located at the top left corner on control panel, is pulled out.

3. When the orange ProtoTRAK TMX screen prompts up, you'll notice the top of the screen displays "servo off."

4. Press the green button at the top right hand corner of the control panel to turn servos on.

5. You will hear the lube pump start up and the prompt will change at the top screen to "servo on".

Homing the machine
Homing the 2op sets the machine home reference positions in the X,Y and Z axis's and will have to be done at each machine start up.
 
The head will move all the way to the right during the homing process, so you want to make sure the coolant lines are clear between the right side of the machine and the spindle as shown in the pics below.
 
wrongcorrect
Just like the X axis, the Y axis will move all the way back toward the operator with the door closed, so the vise and vise handle can not stick out past the table or it could cause damage to the door.
If the vise handle is still attached, remove it completely to avoid any damage to equipment during the homing process and/or running the program.
Normally, you should not have to remove the vise since it is centered on the fixture plate, but if something doesn't look right or you are not sure, see staff!
 
                                      vise handle                                      
Press the SET Home soft key. The next screen will show green message box with the message "Ready to begin. Close door and press go when ready", as shown in the center picture below. 
 
A green box will appear with the message "Please wait" during the homing process as shown in the pic below on the right.

EHW, Resolution and Axis buttons                     
  • These buttons allow you to move the axis selected in DRO or SETUP modes.
  • To do so:
    1. Select a resolution (speed) button
    2. Select the axis you want to move.
  • This will allow you to move the axis selected with the Electric Hand Wheel (EHW).

Zeroing each Axis
To zero an axis or to set an axis to a number, you must be in the DRO mode. Next, select the axis you want set by pressing the axis button.
 
The axis should be highlighted in yellow as shown in the picture below. Now, type the number you wish to enter and press ABS set. 
 
If you press the wrong number or the wrong axis button, press the Restore (RSTR) below the mode button and it will bring you back to where you were before you started.

Tool Setup and Tool Holders

The 2op requires the use of BT30 tool holders with retention knobs which are found in the green tool boxes provided for each of the 2op machines.

  • Keyless and Key chucks - drills, spot drills, edge finders, no endmills

chucks

  • Collet Chucks - drills, endmills, ground shank tooling.

collet holders

  • Endmill holders - ground shank tooling with flats

endmill holders

  • Tool mounting fixture - Used to tighten tool holders

  • Tool setter - used to set Z offsets in the tool table

toolsetter

Endmills with flats

The first tool holder of choice for an endmill with a flat can be seen below. This tool holder has a setscrew intended to clamp onto the flat of the endmill shank. NEVER USE A KEYLESS CHUCK WITH AN ENDMILL!

 
Begin by removing the setscrew to align the flat on the shank with the hole.

Finally, use the tool holding fixture in the vise to tighten the setscrew.

Tools with a round shanks

For an endmill with a round shank, use a collet holder seen below. You may also use the collet holders for drills, spot drills, and any other tooling with a round shank. AGAIN, NEVER USE A KEYLESS CHUCK WITH AN ENDMILL!

Begin by finding a collet that properly fits your tool. The right size for your tool might already be in the holder so check the holders at the top of the toolbox.

If needed, place the selected collet into the holder. To remove a collet from the holder, push the bottom of the collet to the side until it pops out. While placing a collet into the holder, repeat the same process in reverse.

The face of the collet should be in line with the face of the holder as seen below.

Finally, place the tool into the collet and tighten it down. Use the tool holding fixture and wrench found in the green toolbox to tighten the collet, as seen below.

Drills, Spot Drills, and Edge Finders

For all drills and edge finders use either a keyed or keyless chuck. NEVER PLACE AN ENDMILL INTO A CHUCK!

While placing a tool into a chuck ensure the tool is placed as far down as it can go. The first image (left) is incorrect and the second image (right) is correct. Failure to do so can cause incorrect tool offsets.

Tighten a keyless chuck by placing it into the tool holding fixture and using the wrench found in the green toolbox. Note: Not all keyless chucks have the ability to be tightened by a wrench.

Setting tools

Manually load tool into the spindle by pressing and holding the white button while lining up the drive dogs on the spindle with the notches in the tool holder. 

Hold the tool holder until it is seated then you can release the white button.

Press SET-UP mode soft key 

Next press the tool table soft key and that will bring you to the tool table screen shown in the pic below at the far right.

set up modetool tabletool table tool #

Notice the tool numbers from the program are already highlighted in red. 

NOTE:

    • When you upload a GCD file from a CAD file, you will not need to type in the tool diameters in the tool table. The tool diameters are already in the program. (GCD Example below on the left).
    • When programming at the machine (PT4 file), the tool diameters will transpose from your program to the tool table as long as you as create the program first. (PT4 example below on the right).

tool table tool #Tool dia transposed

  •  Grab the tool setter out of the wooden case in the green tool box and place it on the solid jaw of the vise with the indicator facing you as shown in the pic below to the far left.
  •  Position the tool approximately ¼” above the tool setter using the EHW. Press the .0002 resolution key and then the Z axis button if you haven’t already, shown in the center pic below.
  •  Slowly bring the tool down onto the tool setter (using the EHW) until the small dial and the big dial are at 0 as shown in the picture at the far right below.

tool settertool positiontool setter references

  • If the cursor is still on the tool diameter, use the right arrow soft key to move the cursor to the Z offset column or just press ABS set (shown below in the pic on the left). 
  • Now press ABS SET. This will put the value into the Z offset for that Tool #. The cursor will now move to the Z modifier column (shown below in the pic on the right).

cursor                 move cursor

  • Z MODIFIER is used to fine tune your Z depths. Positive values will cut shallower and negative numbers will cut deeper. You will rarely use this function so press ABS set or arrow over to tool type.
  • TOOL TYPE adds a description of the tool along with the tool number. It's not necessary to use, but it is helpful.
    • Follow the prompts in the green box as shown In the pic below in the center. The pic on the right shows an example of the tool type after following the prompts.
