Important notices and safety information
LQ-160Z Metallographic sample large-scale cutting machine is a PLC automatic control metallographic sample cutting machine. It uses control system to drive stepper, servo motor motion control, automatic and precise control of X, Y, Z directions. The hardness of the material changes the feed speed to achieve the fastest cutting effect. The speed of the cutting spindle is controlled by frequency conversion, and the cutting line speed of the cutting blade can be adjusted. Has very high reliability and control.
 

• This machine has electronic handwheel, automatic and random conversion, X, Y, Z manual adjustment and three-speed adjustment, which can better control the moving speed and perform cutting and knife setting. The touch screen displays various cutting data, the display is more accurate, clear at a glance, precise positioning, and better positioning of the cutting workpiece during cutting.

•  This machine has three functional cutting methods: cutting cutting, intermittent cutting, reciprocating cutting and cutting. The cutting speed can be adjusted according to the hardness of the material during cutting, so as to achieve the purpose of quickly cutting the workpiece. When cutting solid steel cylinders, different cutting methods can be selected.

• The design is more user-friendly, and the principle of ergonomics is used. The biggest feature: low noise, convenient operation, beautiful appearance and safe use. It is one of the necessary equipment for laboratory sample preparation.

Brief introduction of each component function

Touch screen：Set the time for the cutting machine to cut the sample; control the start and stop of the whole machine.
Emergency button：Press the emergency stop button of the system, press the system to stop the action, and the system operates normally after turning right.
 

Start button：Press the start button, the system sends power
Stop button：Press the stop button to power down the system.
Main power switch：The power supply switch of the whole system is used to turn off the main power of the machine when the machine is not in use.

Product advantages
The panel is equipped with a touch screen, and start, stop, emergency stop button switches. After the equipment is powered on, turn on the main power switch, press the start button, the system is powered on, and press the stop button, the system is powered off. The emergency stop button is the emergency stop button of the system. Press the system to stop the action. After turning right, the system operates normally. The main power switch is the power supply switch of the entire system. It is used to turn off the main power of the machine when the machine is not in use.

Operation keyboard and display
The main screen displays from top to bottom: cutting main motor working current indication, X.Y.Z position display, spindle speed up and down speed keys and speed display, automatic start and stop buttons, cutting mode display, direction keys, parameter setting buttons.
【Forward/Reverse】Select the running direction of the grinding and polishing disc. If the current is forward, click to reverse.
【Pressure gauge】When using this machine, the pressure gauge should be adjusted to 0.1mpa at first, and then turn the knob (+) to gradually increase the pressure when the machine is running.
[parameter equipment menu] parameter settings such as speed and working time.
From the main screen, click parameter setting to enter 6 sub-screens: X-axis parameter setting, Y-axis parameter setting, Z-axis parameter setting, saw blade parameter setting, sweeping parameter setting, I/O signal debugging and cutting mode Convert button

Click the six parameter settings in the parameter setting to enter their respective setting screens.
The cutting mode buttons can be switched respectively: flat push test cutting, sweep test cutting, and chop cutting;
The horizontal push cutting is completed by the movement of the Y-axis, which is controlled by the cutting distance and cutting speed in the Y-axis parameter setting, and the cutting mode (direct cutting, intermittent cutting, advance and retreat) can also be changed within the Y-axis parameter setting. cutting).
Sweep test cutting is to set parameters in the sweep test parameter setting in the parameter setting.
Chopping cutting is completed by Z-axis motion, controlled by the cutting distance and cutting speed in the X-axis parameter setting, and the cutting mode can also be changed in the X-axis parameter setting (direct cutting, intermittent cutting, advance and retreat cutting) .
 

- Manual speed setting: Set the manual adjustment speed on the touch screen, you can adjust the value according to your needs to control the speed of manual movement.
- Automatic speed setting: Set the automatic cutting speed during automatic cutting, according to the material, hardness and cutting thickness of different workpieces. Set different cutting speeds.
- Cutting distance setting: The setting is set according to different cutting modes. This setting is the setting value of the reciprocating cutting mode. It is used in conjunction with the setting of the retreat distance. The setting value of the cutting distance should be greater than the setting value of the retreat distance.
- Backward distance setting: The setting is set according to different cutting modes. This setting is the set value of the reciprocating cutting mode, and the set backward distance. This setting value is smaller than the cutting distance setting value.
- Cutting stroke setting: The setting is set according to the cutting length of different workpieces. The length of the workpiece to be cut should be greater than the actual cutting size of the workpiece.
- Cutting pause time setting: Set the intermittent pause time, this setting is the pause time after setting the cutting distance setting value, and cut again after reaching the set time, realizing the setting of the intermittent cutting mode.
- The current position of the Y axis: display the current position value, if you want to set zero, you need to press the position reset button and the value will return to zero.
    The Z-axis screen is the same as the Y-axis.
 

X operation screen
Manual speed setting: Set the manual adjustment speed on the left and right of the screen, and adjust the manual speed setting value according to different needs
Current position: Display the current position value, if you want to return to zero, you need to press the position reset button and the value will return to zero.

Saw blade parameter setting
The parameter setting of the saw blade adjusts the rotation setting of the cutting saw blade according to the material, hardness and diameter of the grinding wheel. The maximum speed of this cutting machine is 2600 rpm. The spindle speed can be adjusted at any time by pressing the up and down adjustment buttons on the main screen. Saw blade overcurrent setting: It is a protection setting to better protect the main motor. When the motor current exceeds the set value and reaches the current time setting, the motor will stop running and the equipment will stop working. This better protects the spindle motor. When leaving the factory, the overcurrent of the saw blade is set to 20A, and the overcurrent time of the saw blade is set to 5 seconds.

I/O signal debugging interface
The status display screen shows the status of the system. When the system is faulty, you can enter this screen to check the fault of the system.
Displays the functions of the device, as well as device parameters and precautions.
