QG-4 metallographic sample cutting machineInstallation and use (vertical/desktop)

1. Installation

1. Place the machine flat on a stable workbench, check whether all parts are complete, whether the fasteners are loose, and do a good job of cleaning.

2. Place the cooling water tank in a suitable position on the floor, and inject the pre configured coolant into the tank. However, the coolant must be configured with good lubricity, and general tap water should be avoided as the coolant.

3. Install the power cord of the cooling pump, the outlet pipe connector, and the drainage pipe into the cooling box.

4. Before plugging in the main power cord, check whether the power voltage matches the specified voltage and whether the grounding of the power cord is safe and reliable.

5. Turn on the button switch, start the motor, and check that the direction of rotation of the motor is clockwise. If the direction of rotation does not match, adjust it in a timely manner.

2. Use

1. Open the outer protective cover and install the grinding wheel (already installed at the factory). When loading and unloading grinding wheels, simply press down the support pin on the inner protective cover seat, and then rotate the shaft sleeve by hand to match the pin hole on the shaft sleeve with the support pin. You can use a wrench to loosen or tighten the M16 left-hand nut on the end of the shaft sleeve to achieve the requirements of loading and unloading grinding wheels. However, after each loading and unloading of grinding wheels is completed and the support pin is released, the shaft sleeve should be rotated again to check whether the support pin and pin hole are disconnected, in order to avoid accidents during startup.

2. After installing a new grinding wheel and covering it with an outer protective cover, it must be idle for a few minutes to ensure safety during use.

3. To clamp the sample, first adjust the clamping seat to the proper position, then tighten the nut, loosen the clamping handle, pull out the pressure bar, after installing the sample, push the pressure bar forward until the pressure block contacts the sample, and properly tighten the pressure handle. Once the clamping is completed, the sample can be pressed back with the spring pressure bar before clamping. However, the geometric shape of the sample must be paid attention to, and the correct position must be selected for clamping. For the sample with a special geometric shape, the necessary auxiliary tooling must be used to clamp it. Never clamp it at will to avoid accidents during cutting.

4. After completing the above preparation work, the cutting of the sample can be carried out. Before cutting, open the cooling valve, cover the outer protective cover, and then start the motor and cooling water pump. Then control the operating handle to slowly contact the grinding wheel with the sample for cutting, and do not use excessive force during cutting. Intermittent cutting should be used. And according to the different materials, the cutting speed should also vary. When using, first test at a slow speed. If the cutting machine's speed decreases and the motor's sound is low during the test, immediately retract the grinding wheel and wait for the speed to return to normal before cutting slowly forward. To prevent damage to the motor due to overload or accidents caused by cracking of the grinding wheel, which may affect the normal use of the equipment.

Maintenance and Care

1. After each use, timely cleaning and maintenance work should be carried out, and the dirt in the body and water tank must be regularly removed to ensure the smooth flow of coolant.

2. When performing cleaning and maintenance, a flushing tube (accessory) can be used for flushing, and the cutting cooling valve should be turned off before flushing.

3. Lubricating oil should be regularly injected into each sliding surface during work. After one year of operation, the lubricating grease of the motor bearings should be replaced.

4. The coolant should be replaced regularly to prevent deterioration and failure, which may affect the cutting effect.

5. It is not allowed to use cracked or damaged grinding wheels, and grinding wheels with a maximum speed of less than 35 meters per second for cutting work, ensuring safety during cutting.
