PCM-CNC series CNC turning and grinding machines are specially designed to meet the special processing needs of rubber rollers. Advanced and unique operating system, easy to learn and easy to master without any professional knowledge. When you have it, the processing of various shapes such as parabola convex, concave, large pitch, fine thread, herringbone groove, etc. has changed since then.
Features:
1. Have all the functions of ordinary grinder;
2. The system has comprehensive functions and can meet various requirements for the shape of the rubber roller. For example: convex and concave in parabola; convex and concave in cosine; wavy; conical; large pitch; herringbone groove; diamond groove; straight groove; horizontal groove;
3. The CNC operating system is simple and easy to use.
1. The newly cast rubber roller should not be put into use immediately
Since the internal structure of the newly cast rubber roller is not stable enough, if it is put into use immediately, it will easily reduce the service life. Therefore, the new rubber roller just out of the tube should be placed for a period of time, so that the rubber roller can maintain a relatively stable state after contacting the temperature and humidity of the external environment, which can increase the toughness of the colloid and improve the durability.
2. Correct storage of idle rubber rollers
After the rubber rollers to be used should be cleaned, wrap the colloid with plastic film and store it in a cool, dry and ventilated place, and in a vertical or horizontal state. Do not pile up a few randomly or lean against the wall. , so as not to cause the colloid to suffer undue loss, and also avoid storing it with acid, alkali, oil and sharp and hard substances, so as to avoid corrosion and damage to the rubber roller. After the rubber roller is stored for 2 to 3 months, it should be changed in direction to prevent bending deformation when placed in one direction for a long time, and pay attention to prevent the shaft head from rusting. During the transportation of waste rubber rollers to be processed and cast, do not throw them around or press heavily, and keep the roller cores from eccentricity and bending, so as to ensure the normal use of the roller cores.
3. The shaft head and bearing of the rubber roller should be well lubricated
We know that the accuracy of the roller head and bearing directly affects the effect of ink transfer and ink distribution. In case of poor lubrication
Lifting the head of the rubber roller, the wear and clearance of the bearing will inevitably lead to the disadvantage of uneven printing ink color. At the same time, it will also be caused by jumping glue and slipping glue.
and other bad conditions cause printing streaks. Therefore, lubricating oil should be frequently added to the shaft head and bearing of the rubber roller to prevent the wear of the parts.
The normal use of the rubber roller ensures the printing quality.
4. When the machine stops, the rubber roller and the plate cylinder should be disconnected from contact in time to remove the load to prevent static pressure deformation.
5. When installing and disassembling, it should be handled with care, and should not collide with the roll neck and the rubber surface, so as to avoid damage to the roll body, bending or damage to the rubber surface; the roll neck and the bearing should be closely matched, and if they are loose, they should be repaired by welding in time. .
6. After printing, wash the ink on the rubber roller. To clean the ink, special cleaning agent should be selected, and check whether there is still paper wool or paper powder on the rubber roller.
7. A hardened film of ink is formed on the surface of the rubber roller, that is, when the rubber surface is vitrified, pumice powder should be used to grind it off. When cracks appear on the surface of the rubber roller, grind it off as soon as possible.
In summary, scientific and rational use and maintenance of the rubber roller can maintain its stable mechanical properties, chemical properties and printing suitability, prolong its service life, and play a pivotal role in improving production efficiency and ensuring product printing quality.
