Audited Supplier Important precautions and safety information
1, when using this cutting machine, must comply with these safety matters to avoid fire, electric shock and personnel injury.
Read and understand all usage rules.
Remember the common sense of electrical use.
Comply with all warnings and rules indicated on the product and in the documentation provided with the product.
If there is a conflict between the rules of use and the safety information, obey the safety information; If you cannot resolve the conflict, please ask the seller or service agency for help.
When cleaning the outside of the machine, please unplug the power plug, do not use cleaning liquid or kerosene, only use a wet cloth to clean the machine.
Do not place the device on an unstable table; otherwise, the device may fall and cause serious damage.
Do not place any items on the power supply or cutting machine.
Do not overload the power latch plate on the wall to avoid fire or electric shock.
To avoid the risk of electric shock, do not disassemble the cutter. If repairs are required, they should be repaired by a qualified repairman. Opening or removing the lid of an appliance can expose you to dangerous voltages or other hazards, and improper reassembly can result in an electric shock in later use.
In the following cases, unplug from the wall and ask qualified maintenance personnel to repair:
a The power cable, plug, or connection cable is damaged or worn.
b Operate the cutting machine according to the rules, but the machine does not work.
c The cutting machine falls or the casing is damaged.
d The performance of the cutting machine has suddenly changed significantly.
11. Only the parts mentioned in the instruction manual are allowed to be adjusted.
12. Keep this manual.
The purpose of the cutting machine
This machine is suitable for cutting all kinds of metal, non-metal material samples, in order to observe the material metallographic, lithographic structure. The machine has a circulating cooling device, the use of the configured coolant can take away the heat generated during cutting, to avoid the sample overheating and burn the sample tissue. The machine is easy to use, safe and reliable. It is one of the necessary equipment for making samples in laboratories of factories, scientific research institutions and universities.
Cutting machine main technical indicators
Power supply: three-phase four-wire (380V, 50HZ).
Spindle speed: 2800 RPM
Grinding wheel size: 250×2×32mm
Maximum cutting diameter: φ80mm
Input power: 2.2KW
Size: 650*715*545mm
Weight: 117kg
Install the machine
The machine should be placed flat on a stable workbench.
Install the water inlet pipe, and the water outlet pipe should be lower than the water inlet of the body to avoid poor drainage.
Check whether the power cord, plug connector and other electrical components are intact, then connect the power supply, start the motor, the motor should be marked according to the direction of the machine.
Note: The electrical apparatus of this machine should use three phases and four wires, and the ground wire must be grounded.
Wheel loading
Open the upper cover of the machine, and unscrew the pagoda cap at the spindle end with the wrench provided, that is, remove the grinding wheel clamp and grinding wheel blade.
Install the grinding wheel piece and the grinding wheel clip on the spindle, tighten it properly with a wrench, and then rotate the spindle twice by hand to check whether there is swing on both sides of the grinding wheel piece, and the swing momentum is not greater than 2mm. If it is more than 2mm, check the cause and reinstall it.
Sample mounting
The correct clamping of the sample is an important guarantee for safe and reliable work. During operation, put the work into the clamp mouth, lock the clamp mouth with a wrench, push or rotate the sample by hand, and check whether the working clamp is stable, otherwise it should be re-installed.
Sample cutting
After completing the preparatory work mentioned in the above method of use, the sample can be cut. When cutting, cover the upper cover of the machine first and open the coolant switch to make it have enough cooling flow. Start the motor, and then hold the swing arm handle, let the grinding wheel slowly contact the sample, cutting, cutting should be uniform force, do not exert too much force.
Attention:
The cutting force should be uniform, do not exert too much force, it is recommended that every cut 1-2mm, slightly lift the grinding wheel.
The coolant must be configured with a better lubricity coolant (random gift), and the use of general tap water as a coolant should be avoided.
For the cutting of rock, ceramic and other samples, diamond grinding wheel pieces must be used to cut.
The power supply must be cut off when clamping the workpiece.
Maintenance and safety technology
The machine adopts three-phase four-wire system, and must be installed with reliable grounding wire.
The water inlet and drainage pipes must be unobstructed but must not leak
Do not use cracked or damaged grinding wheels to cut samples.
Grinding wheels with line speeds below 35 m/s are not allowed to work
After each operation, cleaning and maintenance work should be done in time. Remove and clean the filter screen at the left rear water outlet of the machine table to ensure smooth drainage.
After one year of operation, the spindle and motor bearings should be replaced with high-speed grease on time.
The coolant should be replaced regularly to prevent deterioration and failure.
When the machine is found to have abnormal sound, it should be stopped immediately for inspection.
Fill the machine with lubricating oil regularly.
