Audited Supplier Important precautions and safety information
1. In the process of metallographic sample preparation, material cutting is the first process of sample preparation. In order to achieve the best sample cutting in a safe state, the cutting machine uses a high-speed rotating wafer reinforced grinding wheel to cut the sample. In order to avoid burning the material tissue during sample overheating during cutting, the machine is equipped with a cooling system to take away the heat generated during cutting.
This machine has the advantages of easy operation and use, easy maintenance and so on, and are superior to similar domestic products, cutting range and transmission power are also greater than similar domestic products, is the best choice of sample cutting equipment.
Maximum cutting section: Φ50mm
Grinding wheel size: 300×2×32mm
Speed: 2800r/min
Input power: three-phase 380V, 50HZ
Cutting power: 2.2KW
Dimensions: 460*515*395mm
Net weight: 67kg
The motor (1) is fixed on the base (2), and the shaft sleeve (3) is fitted on the shaft on the motor (1). The nut (4) holds the clamping plate (5) firmly against the grinding wheel plate. The support (7) is fixed in front of the motor, the saw frame (8) is set on the cross axis (9) of the support, and can be moved up and down around the cross axis by the handle (10). The clamp base (11) is fastened to the saw frame, and the clamp mouth (12) can be moved forward or backward to tighten or loosen the cutting sample by rotating two locking screws. The water valve (13) and the spray pipe (14) are installed on the water plate (15), and the flow rate of the coolant is adjusted through the knob. The cover shell (16) is fixed on the base and support with hinges and screws to prevent the coolant from splashing and prevent the grinding wheel from flying out when the wheel is broken occasionally.Installation and use
First, installation:
1, the machine flat on a stable workbench, in the installation, the front should be slightly higher than the back to facilitate drainage.
2. Install the water inlet pipe and drain pipe.
3, the drain pipe to the sewer, be careful not to make the height of the drain pipe more than the drainage hole, so that the water in the machine smooth outflow.
4, plug into the power socket, and check whether the power supply voltage is consistent with the specified voltage of the motor, grounding is safe and reliable, after starting the motor, the rotation direction of the motor shaft should be rotated clockwise (that is, the spark down when cutting), if the steering does not adjust the steering immediately.
Second, the removal and replacement of the grinding wheel:
1. Remove the screws fixing the cover first, and then open the cover back.
2, first insert a wrench into the two planes of the shaft sleeve to jam the shaft sleeve, and then insert another wrench into the front nut of the shaft sleeve, and use both hands to tighten or loosen the nut to achieve the requirements of installing and disassembling the grinding wheel. Because the nut is left-handed thread, it must pay attention to the turning direction when assembling and disassembling.
3, the newly installed grinding wheel must be idled for a few minutes to ensure safe operation.
Third, sample clamping:
1, first use the support plate to support the saw frame not to make it fall.
2. Place the cutting sample in front of the jaws of the saw frame and then rotate the tightening screw clockwise to tighten the sample. If necessary, the board can be further tightened.
Four, sample cutting:
1. Lift the handle with the right hand and remove the support plate from the support point with the left hand. At this time, hold the handle with the right hand so that the sample is close to the grinding wheel and cut.
2, when cutting, the coolant must be aligned with the cutting position of the sample, and maintain uniform feed at the same time. The coolant size should also be adjusted to the cutting requirements, so as not to spill out of the machine.
3. After cutting, lift the saw frame to a certain height, and the support plate will automatically support the saw frame in a certain position, and then the sample can be obtained.
Maintenance and safety technology
1. It is strictly prohibited to use cracked or damaged grinding wheel for cutting.
2, should not work in the absence of coolant or insufficient coolant,
3, do not allow the use of line speed less than 35 meters/second grinding wheel.
4, the machine should do cleaning and maintenance work every day, each rotation should be injected with lubricating oil before operation.
5, the body accumulated debris and garbage should be removed frequently, so that the drainage is smooth.
6, the motor should be maintained according to the motor maintenance method.
