- Micro-electric engraving machine is not invented by us
- However, we work for its quick and accurate rotation every day.
- We can ensure that our products can meet customer various requirements
- including details since our micro-electric engraving machines are composed of
- first-class and precise components. Even though it is not us who invented
- micro-electric engraving machine, we still require our products can achieve
- seemingly impossible task. We will step up technological innovation relentlessly
- so as to achieve new goals.
How To Choose And Buy High Quality Product?
A.Control box part:
1. AppearanceModeling fluent convenient operation, color and luster is natural; the edge of hand without scraping the flash, surface and surface indirect suture level off, aperture is consistent, fixed screw firmly to the completeness of the contents, the operation key indicator clear, clear
2. Voice
Electricity turns on the power switch after, no obvious transformer the resonance of the sound, no vibration sense.
3. Operational keys feel
The operation key feels smooth, without damping feeling, the spring back nature.
4. Temperature rise
In the process of work no obvious hot feeling (tepid feeling is normal)
B.Mobile phone part：
1. Appearance
No bruising and nick, do manual work is delicate, color collocation is reasonable, the overall visual feeling comfortable
2. Noise
Handle in high speed rotating the sound when should be consistent, all the high and low, no obvious sharp or too depressing sound, no other noise
3. Concentricity
The standard of needle inserted inside the handle (usually accompanied with needle detector) need to plug it, hand took the handle the tail, will spin put the needle on a gently pad is (don't need hard hold), gradually raise the speed to 15000 turn every minute, the quality of miniature electric grinding carving machine won't have obvious sense of beating, the feeling of beating smaller may be more beautiful, quality of concentricity should be controlled in less than 0.02 mm. Jitter directly affect the service life of the machine, the work of the hands of the processing quality and operator fatigue.
4. Temperature rise
Good miniature electric grinding carving machine should not have a hot feeling, the influence of the temperature reason has bearing, motor quality, the precision of the machine parts, etc. So choose high quality parts is whole the quality of security.
5. Power
Big power-twist to strong, high speed, high velocity and grinding, cutting efficiency is high, can satisfy different material on the high request
6. Touch
The structure of the product appearance design is reasonable, when using, take in the hand feel comfortable
