What should I pay attention to when purchasing a polishing machine, and how to use the polishing mac

Steps:

1. Turn on the machine and unscrew the "emergency stop" button;

2. Adjust the sink clamp position to properly clamp the sink, record the data of each card position, and take pictures of the caliper position (note: align the downspout with the center of the turntable);

3. Number the program name and "reset" it to its original position;

4. Adjust the depth of the grinding wheel, pay attention to adjust the lower limit position of the sensor and the position of the screw;

5. Clear the existing data "Data Zero", press "Debugging Stop", "Debugging Start" light on, debugging starts, the steps are as follows:

"Before the grinding wheel", move the grinding wheel forward to the appropriate position;

The workpiece is "rotating the workpiece at an angle;

After grinding wheel", move the grinding wheel back to the appropriate position, so that the grinding wheel is in close contact with the arc of the sink.

6. Complete the debugging, "monitor" the data, and check whether there is abnormal data. if so, amend it;

7. After the correction is completed, press "Debugging Start", the debugging start light will be off, and the debugging will be completed; Adjust to "Auto" gear, then "Reset", turn on "Auto Start", and test throw the sink;

8. Check the polishing effect, make corrections, and complete the debugging.

Precautions: 1. During the debugging process, do not press the "grinding wheel stop" button;

2. Only when the grinding wheel moves forward to the position of the limit point in front of the sensor, the "grinding wheel down" operation can be carried out;

3. Press the grinding wheel as hard as possible at the corner and correct the corner position;

4. At the junction of the wide side and the narrow side, switch the speed of the grinding wheel;

5. Do not put your hand under the screw when adjusting the depth of the sink.

When you first start throwing, don't adjust the number of revolutions too high, and then the sponge ball should not be flat against the body, just a little oblique.

Take it with both hands! Grab the handle, I've used it before, it's not hard to use.

The key to the operation:

Try to get the maximum polishing rate so that the damaged layer that occurs during polishing is removed as quickly as possible. At the same time, it is also important to ensure that the damaged layer does not affect the final observed tissue, i.e. does not cause false tissue. The former requires the use of coarser abrasives to ensure a larger polishing rate to remove the polished damaged layer, but the polishing damage layer is also deeper; The latter requires the use of the finest materials, resulting in a shallower layer of polishing damage but a low polishing rate.

The best way to resolve this contradiction is to divide the polishing into two stages. The purpose of rough polishing is to remove the polishing damage layer, and this stage should have the maximum polishing rate, and the surface damage caused by rough polishing is a secondary consideration, but it should also be as small as possible; The second is fine polishing (or final polishing), the purpose of which is to remove the surface damage caused by rough polishing and minimize polishing damage.

When polishing the polishing machine, the grinding surface of the specimen and the polishing disc should be absolutely parallel and evenly pressed on the polishing disc, taking care to prevent the specimen from flying out and new grinding marks due to too much pressure. At the same time, the specimen should be rotated and moved back and forth along the radius of the turntable to avoid local wear of the polished fabric too quickly, and the fine powder suspension should be continuously added during the polishing process to keep the polished fabric at a certain humidity. If the humidity is too high, the grinding scars of polishing are weakened, and the hard phase in the sample is embossed, and the non-metallic inclusions in steel and the graphite phase in cast iron produce the phenomenon of "tailing". If the humidity is too low, the sample will heat up due to friction and heat, the lubrication effect will be reduced, the grinding surface will lose its luster, and even black spots will appear, and the light alloy will throw off the surface.

In order to achieve the purpose of rough throwing, the rotation speed of the turntable is required to be low, and it is best not to exceed 500r min; The polishing time should be longer than it takes to remove the scratches, as the deformed layer also needs to be removed. After rough polishing, the grinding surface is smooth, but dull, and there are uniform and fine grinding marks under the microscope, which need to be eliminated by fine polishing. The speed of the turntable can be appropriately increased during fine polishing, and the polishing time is appropriate to throw away the damaged layer of rough polishing.

The polished surface is as bright as a mirror, and scratches are not visible in the microscope's bright field of view, but they are still visible in phase contrast lighting.

Kunshan Qixin grinding machinery.

First of all, we understand the quality and goals required by customers.

Then choose a compatible polishing material (from coarse to fine).

There is too little information you should provide.

Therefore, it could not be more detailed.

1. Use.

The polishing machine is used to remove the grinding grooves left by the grinding wheel of the grinding machine after the optical resin sheet and glass sheet are edging, so that the edge surface of the lens is smooth and smooth, so as to prepare for the installation of rimless or half-rim glasses.

Second, the working principle.

The polishing machine consists of an electric motor and one or two polishing wheels. The polishing wheel is rotated at high speed by an electric motor, so that the part to be polished of the lens is in contact with the polishing wheel coated with polishing agent to cause friction, and the edge surface of the lens can be thrown to a smooth and bright surface.

There are two types of polishing machines. One is to follow the glasses frame polishing machine and modify it, which can be called a vertical polishing machine. The polishing wheel material uses laminated cloth wheels or cotton silk cloth wheels.

The other is a newly designed special polishing machine for lenses, called a right-angle plane polishing machine or a horizontal polishing machine. It is characterized by the fact that the polishing wheel surface is inclined at an angle of 45° to the operating table, which is convenient for processing operations, and when polishing, the lens is in contact with the polishing wheel surface at a right angle, which avoids the accidental abrasion caused by the non-polishing part. The polishing wheel is made of ultra-fine emery paper and compressed thin fine felt.

Ultra-fine sandpaper is used for coarse polishing, and thin fine felt has a special polishing agent for fine polishing.

3. How to use.

Tools: polisher, polishing agent.

Steps:Coarse polishing: a. First of all, rotate the threaded rod of the polishing wheel counterclockwise, install a thin fine felt under the disc, and install ultra-fine sandpaper on it, and use ultra-fine sandpaper to polish the surface.

b. Hold the lens with both hands, make the lens at a right angle to the polishing wheel surface, and then gently touch it for polishing.

Fine polishing: Replace the ultra-fine sandpaper, add a thin fine felt polishing wheel and evenly apply the polishing agent, and then polish it in the same way as the rough polishing (note: when polishing the glass lens, only the ultra-fine sandpaper is needed for polishing).

The original article is from Jinzhu Machinery:

There are many types of polishing machines, what kind of machine is it.

The use method is divided into two steps: 1. The operator first connects the power cord to the socket, and the switch is set in the "off" position; 2. Grinding: Turn on the power switch when polishing, then adjust it according to the specified speed, and then place the polishing machine flat on the paint surface and apply pressure down evenly to carry out the polishing operation. The amount of pressure applied is flexibly determined by the operator according to the degree of polishing of the paint finish; Precautions when using the polishing machinePersonnel who have not undergone professional training are strictly prohibited from using the polishing machine.

Trained professionals must also be proficient before they can operate on the job. When the machine is just started, the speed of the polishing machine can not be adjusted too fast, the strength should not be too large, you must first try to throw the paint surface in an inconspicuous place to ensure that the whole car can be polished after ensuring normal.

How to use stainless steel polishing machine, it is very important to master the steps! Have you learned.

Hello, it is mainly divided into:

1) Press power**There are two kinds of pneumatic and electric. Pneumatic type is safer, but it requires an air source; The electric type is easy to solve the power supply problem, but you must pay attention to the safety of electricity.

2) According to the function, there are two kinds of dual-function industrial frosting and polishing machine and simple polishing machine. The dual-function industrial frosting and polishing machine can be equipped with a grinding wheel to polish metal materials, and can be replaced with a polishing disc for car paint protection. This machine is heavier, 2-3 kg, but it works very smoothly and is not easily damaged.

The speed of this model can be adjusted, making it suitable for beauty professionals. The simple polishing machine is actually a drilling machine, which is small in size, the speed is not adjustable, and it is difficult to grasp the balance when used; This type of model is generally not used by beauty professionals.

3) There are three kinds of polishing machines according to the speed: high-speed polishing machine, medium-speed polishing machine and low-speed polishing machine. The speed of the high-speed polishing machine is 1750-3000 r man, and the speed is adjustable; The speed of the medium-speed polishing machine is 1 200-1 600 r rain, and the speed is adjustable; The speed of the low-speed polishing machine is 1 200r min, and the speed is not adjustable.
