Limit switch is the hardware sensor equipped on limit position of the two ends of each shaft. After detecting
limit triggering signal, the movement shaft will perform emergency stop to avoid “overreaching”. Minimum one
limit switch is needed for each shaft to indicate limit position of the current shaft. The installation position of limit
switch may differ due to different types of machine, so the triggering signal. Therefore, configuration is needed.
Zero point of the machine is a referential point of a certain hardware fixed in processing breadth. Generally,
after power-on, “reset” is needed for the machine to create coordinate of lathe.
Attention
At ex-factory, configuration of parameters for stroke, limit and reset has been already performed.
Unauthorized change of parameters by user before making clear its meaning is prohibited. Otherwise, failure of the
equipment may possibly be caused.
3.3.2.3 Straightness and perpendicularity
Before starting formal processing, testing of movement straightness of each movement shaft and
perpendicularity of X-axis and Y-axis are needed. The straightness ensures movement accuracy and stability of
movement for this shaft. The testing shaft can be controlled to move along a straight line. If the straight line is
measure unstraight, it means twittering exists during movement of the shaft, and a solution is required. Reasons
for straightness of single shaft frequently lie in transmission of the motor or mechanical movement and machine
vibration.
Movement coordinate system of the machine is a rectangular Cartesian coordinate system. Theoretically,
X-axis and Y-axis should ensure be in absolute uprightness to ensure processing accuracy. If case of large
tolerance for the straightness, distortion of the processed figure will be caused. Method of measuring the
straightness is to have the control equipment go a rectangle frame on the surface of processing, and measure if
the length of four sides and diagonal are the same. Method of adjusting perpendicularity is to make adjustment of
assembly of X-axis and Y-axis movement mechanism.
Attention
Debugging of straightness of perpendicularity of each shaft has been already performed at ex-factory of the
equipment. In case of problems found by users, please timely contact our customer service personnel for a solution.
Unauthorized disassembly of the machine is prohibited.
3.3.3 Laser debugging
Laser debugging contains two aspects: light emitting test and light route adjustment. The followings are the
details for them:
3.3.3.1 Light emitting test
After normal power up, press the laser power switch on the right side cover, and then set the light emitting
energy and time directly on the control panel, and test if the laser emitting function is normal. If there is no laser
emitting from the spot spray laser tube, it means that there is problems with the laser emitting, and check is
required. In case of laser emitting found from the laser tube, but no laser emitting from the cutting head, it means
improper position of the light route, and adjustment of light route is needed.
If there is no laser emitting, first check the setting of laser parameters. Improper laser parameters may cause
equipment malfunction or laser power cannot be adjusted. If the laser parameters are determined correct and
there is no emitting still, you need to check the hardware problem.
The control panel of some types of machine is equipped with ammeter. With the ammeter, you can check if the
power is normal.
