TRAK LPM Programming, Safety, & Operating Manual
Note - Maximum work capacities are dependent on a lot of variables that cannot be
controlled by the machine manufacturer. Each one of the following will have an impact
on the above numbers: speeds, feeds, cutter, cutter sharpness, material, setup, coolant and
machine adjustments.
3.3.4 Electrical Cabinet
The electrical cabinet is found at the rear of the LPM on the right side. The electrical
cabinet contains the main control hardware for the machine. The main components are as
follows: computer module, AC spindle drive, servo drives, input/output modules, relays
and contactors.
3.3.5 Computer Module
The computer module is the heart and soul of the machine. All of the inputs and outputs
are feed through this module. The computer module controls the program panel, run
panel, AC spindle drive, servo drives, motor signals and feedback and input/output
modules. Inside of the computer module is a motherboard, motion control board and an
applications board along with a power supply.
The computer module also contains 4 more USB ports and a network port. We ship the
machine with 3 USB ports having something plugged into them. The 3 USB ports
contain the following: machine option key, a D drive for part storage and an overlay
interface USB cable. The network port is available to the user if they want to network the
control to an offline computer or network.
3.3.6 Servo Motors
The LPM can run up to 4 axis motors. The 4th motor would be used to control a 4th axis
indexer. The motors used on the X and Y axis are rated for 4.2 ft/lbs of torque. The Z
axis motor is rated at 8.11 ft/lbs and also contains a mechanical brake the holds the head
in position when the power is turned off to the machine.
3.3.7 Servo Drives
The LPM can also contain up to 4 servo drives. The 4th amp would be used to control a
4th axis indexer or rotary table. The servo drives receive signals from the computer
module, which in turn send signals to the servo motors.
3.3.8 Spindle
The spindle is contained within a cartridge and CAT 40 tool holders must be used. The
spindle bearings are permanently lubricated and require no additional attention by the
user. The spindle is also air cooled, and has an air purge system that is automatically
activated during the tool change sequence, it blows air down the spindle to prevent chips
from being trapped between the holder and spindle taper.
Warning!
The spindle unit is not field serviceable. If the bearings go bad the
entire spindle cartridge will be replaced.
