3.Equipment instructions
3.1.Processing flow
Step 1: the material to be processed is fixed on the machine with the
corresponding fixture. Generally, the thin plate is fixed by double-sided
glue, the rectangle is fixed by a vise, and the shaped workpiece is fixed by
a special fixture.
Step 2: Clamp the tool onto the spindle motor. When clamping the tool, it
is necessary to pay attention to the specifications of the clamping tool. It
must be the same as the programming time. The tool should be locked
with the spindle wrench. After the tool is clamped, it must be checked
whether the tool will be yawed. Otherwise, the quality of the processed
product will be poor. Broken knives, etc. during processing.
Step 3: Open the control software Mach3 on the computer, turn on the
machine power switch, and release the alarm state.
Step 4: manual tool setting operation, press the keyboard “Tab” on the
computer operation interface to call up the “MPG” interface, click the
corresponding button to control the forward/reverse movement of the
machine in the current axis. by To
control the speed of the movement, move the center of the tool nose to
the machining coordinate origin set during programming (for the
convenience of tool setting, the programming is usually set at the four
corners or the center of the material). For example, when programming,
the origin is set in the lower left corner of the material, then we will align
the center of the tool tip with the bottom left corner of the material with
the hand wheel (the spindle speed should be adjusted to about 30% when
the tool is set to prevent the tool from breaking. Knife).

Step 5: Confirm that the “Emergency Reset” in the lower left corner
of the software is not flashing. Click “Zero X”, “Zero Y”, “Zero Z”,
“Zero A”, click “Load G Code”, then there will be loading. G code
pop-up window, file type select "AllFiles" and find the G code you
generated is loaded. After the loading is completed, the corresponding
simulation path will be displayed in the upper right corner of the software
(if there is no simulation path generation, the loaded G code is wrong
or Can't identify it).
Step 6: After the program is read in, adjust the spindle speed to
80%~100% (the spindle speed is set according to the processing
material), then click “Start” to process the machine. If it needs
to be adjusted during the machining process. The speed of the
machining can be controlled by pulling the column bar of the
feed bar.
The above is a simple operation method. For details on the control
software, please refer to “Using Mach3Mill”.

6. Equipment service
(1) screw cleaning and lubrication
When the machine is in use, it is a good habit. It is necessary to do a cleaning
work for about one month. The screw, optical axis and bearing cleaning must
work. You can use a clean rag to manually wipe the optical axis of the screw.
The part of the bearing that is not cleaned can be cleaned with a small brush.
After cleaning, the oil can be sprayed with oil to the screw, the optical axis and
the bearing, and then the machine can be moved back and forth for a few times,
such as above the screw. There is also dirt, re-clean with a rag, repeat the
lubrication and clean the action until the screw is shiny and oily.
(2) spindle cleaning and maintenance
During the machining process, the spindle chuck, nut and screw parts are easy to
enter dust and rust. At this time, it is necessary to apply anti-rust oil to the spindle
clamping part to clean the rust of the screw; the chuck and nut are severely rusted.
Replace the collet and nut to ensure that the machine is concentric.
(3) electric control box cleaning
When the controller is used with the machine, sometimes it will enter a lot of dust.
When processing metal materials, it is necessary to clean the dust inside the control
box to prevent conduction and burn out the circuit. We can open the cover of the
controller, use a hair dryer, open the cold air stall, turn the control box upside down,
clean the dust on the circuit board, and clean it, clean it with a small brush.
