Traditional polishing process of eyeglass frame:

1、 Polishing preparation

1. Determine the mirror frame material to be polished;

2. Determine the yarn wheel material according to the frame material and adjust the yarn wheel;

3. Determine the sand powder material according to the mirror frame material;

4. When the sand powder materials used after polishing are different, the yarn wheel should be cleaned before polishing;

5. Put the determined sand powder into the sand bucket, inject water appropriately, and adjust it to a certain humidity.

2、 Throwing circle

1. Determine the position to be polished and the degree of polishing;

2. Hold the ring with both hands and pull upward from the downward direction (manual direction);

3. When casting the blank front, the blank front is close to the yarn wheel, and the nozzle position is slightly forced;

4. Polishing sequence: from left to right, from top to bottom;

5. When throwing Zhuangtou, the technique should be light and not hurt Zhuangtou;

6. Timely water the sand, timely sand, after the sand shovel with the yarn wheel slightly forward;

7. Check the thrown mirror ring to make sure that the parts to be thrown have met the requirements;

3、 Throw away

1. Determine the position to be polished and the degree of polishing;

2. Hold it with both hands and pull it upward from the downward direction (manual direction);

3. When throwing the body, start from the middle and throw it to both ends successively;

4. When polishing the tail, it can be polished in groups. The tail end of a group must be flush, and the polishing force should be equal;

5. Polishing sequence: from left to right, from top to bottom;

6. Timely water the sand, timely sand, after the sand shovel with the yarn wheel slightly forward;

7. Check the throwing parts to make sure that they meet the requirements;

4、 Throw away the shelf

1. Generally, the throwing frame is thrown first and then the throwing circle, starting from the tail of the throwing frame, and the order is: throwing (upper) --- circle (upper) --- throwing (upper) --- throwing (lower) --- circle (lower);

2. When throwing the loop, hold the loop with both hands and keep the loop tail away from the yarn wheel as far as possible to prevent the loop tail from being interrupted by the yarn wheel;

3. When throwing the yarn, hold the loop in one hand, hold the yarn in the other hand, and keep the yarn away from the yarn wheel as far as possible, so as to prevent the yarn tail from being interrupted by the yarn wheel;

4. When throwing Zhuangtou, the technique should be light and not hurt Zhuangtou;

5. Timely water the sand, timely sand, after the sand shovel with the yarn wheel slightly forward;

6. Check the frame to be thrown and make sure that the parts to be thrown have met the requirements;

5、 Throwing wax

1. Determine the frame to be polished and determine the polishing property of the frame;

2. Determine the polishing position, degree and procedure;

3. Prepare polishing materials (white wax and red wax) according to polishing procedure;

4. Turn on the machine and start polishing;

① The order of increasing the brightness of the frame is as follows: 肶 (outer) - circle (outer) - 肶 (outer) - 肶 (inner) - circle (inner) - 肶 (inner), with or without polishing in the frame according to the actual situation;

② Polishing position, polishing procedure and force should be determined according to the nature of defects;

③ Generally, red wax is thrown first, then white wax is thrown, or only white wax is thrown;

5. When throwing the loop, hold the loop with both hands and keep the loop tail away from the yarn wheel as far as possible to prevent the loop tail from being interrupted by the yarn wheel;

6. When throwing the yarn, hold the loop in one hand, hold the yarn in the other hand, and keep the yarn away from the yarn wheel as far as possible, so as to prevent the yarn tail from being interrupted by the yarn wheel;

7. When throwing Zhuangtou, the technique should be light and not hurt Zhuangtou;

8. Timely wax the yarn wheel;

9. After throwing, check the lens frame to make sure it meets the requirements;

10. Frame, mark and count the frame.

The above is the traditional eyeglass frame polishing process, very cumbersome, the efficiency is also very low. But using plasma polishing equipment to polish the glasses frame is not the same, whether it is the process or efficiency, it is simple and efficient, and the quality is stable. Next, we will understand the concept, working principle, application scope and characteristics of the plasma polishing equipment for glasses frame, and have a comprehensive understanding.

It is easy to learn and efficient to polish the eyeglass frame with plasma polishing equipment

Plasma (plasma) polishing machine is a kind of surface treatment equipment for conductive metal polishing, which can remove the edge burr of stamping parts in a short time and make the workpiece polished to the mirror effect. Therefore, plasma (plasma) polishing machine is especially suitable for the eyeglass frame manufacturing industry.

Principle of plasma polishing:

Plasma, also known as the fourth state of matter, is an electromagnetic gaseous discharge phenomenon, which partially ionizes gaseous particles. The ionized gas includes atoms, molecules, atomic clusters, ions and electrons. Plasma is in high temperature and high pressure, the polishing agent is water-soluble, the electron will leave the nucleus and run out, the nucleus will form a positively charged ion, when these ions reach a certain number can become plasma state, plasma state energy is very large, when these plasma and the object to be polished friction, instantly will make the object to achieve the surface bright effect.

This new metal surface treatment process only reacts with plasma in the molecular layer of the workpiece surface. The atomic spacing in the molecule is generally 0.1-0.3 nm, and the treatment depth is 0.3-4.5 nm. The surface roughness of the polishing material is in the range of 1 mm, so the plasma chemical activation of the workpiece surface can remove the surface molecular pollution layer and cross connect the surface chemical substances. Product characteristics after polishing: lower roughness, higher finish, higher precision, hard and durable, lower notch sensitivity, smooth and neat, lower friction coefficient and wear. Applicable materials: stainless steel, titanium, aluminum, copper, silver, zinc, alloy and other conductive materials.

Application range of plasma polishing:

Plasma (plasma) polishing technology is specially used for stainless steel, titanium, white copper, beryllium copper and other materials mainly used in the eyeglass frame. It can easily solve the burr edge caused by stamping, treat the workpiece surface and dead corner to achieve the mirror effect, enhance the anti-corrosion performance of the polished surface, and effectively prevent oxidation.

Features of plasma polishing equipment:

1. Improve production efficiency, reduce production costs: any size of the workpiece can be completed in a few seconds to two minutes, to achieve pearl nickel / mirror effect;

2. Full automatic control and easy operation: ordinary personnel can operate normally in 1-2 days after training;

3. Safety and stability, simple maintenance: set up protection induction, prevent accidents, humanized design, convenient maintenance and inspection.
