What is Micromotor?

The Micromotor is composed of a control box and an electric grinder pen. The control box outputs a DC stabilized power supply after being transformed and ballasted. The electric grinder uses a DC motor as the driving source.
The force transmission of the holding structure drives the grinding head to perform the high-speed rotating mechanical movement. Equipped with grinding heads of different materials and shapes, grinding or cutting operations are performed on the working surface.

Applications

Choose grinding heads of different materials, shapes, and models to grind, polish, engrave, seal, hollow, drill, grind, deburr, and other operations on almost all processing surfaces of different materials.

Because of its lightweight, almost no jitter, small head beating (high quality can reach within 0.02mm), small size, and the head diameter is about 20mm, the user will be handy to operate, and the user will not feel the hand for a long time. Fatigue, the workpiece surface is flat, smooth, and high-precision, so the application field is very wide:

1. Jewelry micromotors

The carving, hollowing, and polishing of jewellery and jade make whatever you want. Polishing and grinding during the processing of gold and silver jewelry reflect its small and exquisite side. Overall, This is universal jewelry equipment you can't miss

2. Dental laboratory micromotor

In denture processing, the process of grinding the resin teeth is required to increase the contact surface. In the operation, different grinding heads need to be replaced, which requires an electric grinding machine with high grinding accuracy and convenient operation.

3. Manicure

It can be used for polishing, sanding, trimming, peeling, nail removal and other steps during nail art, especially in nail salons, which can efficiently complete nail art needs, saving half of the time than traditional tools, achieving, efficient, safe, and High income. Micromotor as an electric nail drill machine now become more and more popular in the word.

4. Mechanic polishing-mold trimming

The mold is polished and engraved with the feed opening, and the wool wheel and the grinding paste can be used for fine polishing to give a mirror-bright effect. Grinding for mechanical maintenance, the size of the margin can be controlled at will. Deburring, shaping, and polishing of small parts in mechanical processing units can replace manual files. Large margin processing of seal engraving, fast and delicate.
The sharpening of household knives, the name seal carving on the camera and other electrical appliances, the production of small crafts to demonstrate the fun and uniqueness of your own hand-made.

5. Craftsman polishing-woodcarving
When processing large margins on wood, choose milling cutters for engraving and hollowing. When rough grinding and fine grinding, choose different thicknesses of sand rings to gradually meet the requirements of coarse surface to fine surface. When polishing, use cloth wheels to achieve the effect of a bright surface. It is most suitable for the use of wood carving, root carving, micro-carving artwork, and processing plants. Compared with the use of conventional hand tools, the efficiency can be increased by 5-10 times. The carving and hollowing of walnuts, gourds, and other nuts are even handier. Polishing and grinding during the model making. And the operator does not feel tired. Regardless of whether it is on flat or round glass, with a diamond grinding wheel, under the hands of a superb technician, a lifelike picture will be displayed immediately.

How to use

1: Open the package, take out the items that need to be used such as the control box and mobile phone, and read the instructions carefully.

2: According to the material and processing shape of different processing surfaces, choose the grinding head of different materials, shapes, and models. Hold the knob in the middle of the phone with the palm of your left hand up, and hold the back part of the phone with the palm of your right hand down, and gently rotate your left hand inward and right hand outwards. When you hear a click, it means that the chuck on the head is loose, Take out the inspection grinding needle delivered by the new machine and replace it with the selected grinding head. The grinding head exposes the mobile phone for about 15 mm, and then gently rotates it in the opposite direction to the previous one. A rattling sound is heard, indicating that the grinding head has been clamped.

3: Wear protective glasses to prevent small particles rotating at high speed from flying into the eyes during processing.

4: Plug in the control box (please read the nameplate on the control box carefully, whether the voltage is consistent with the voltage of the external power supply), turn the speed control knob counterclockwise to the end (the straight speed control knob slides to the left to the end)

5: Insert the mobile phone into the socket of the wire and insert it into the corresponding socket of the control box

6: Slowly adjust the speed button to the ideal speed value, and then you can operate it. It is necessary to change the start/stop or speed frequently during processing. It is recommended to use a footswitch to greatly improve work efficiency.

Maintains

How to clean up dust?

Because the motor handpiece miniature high-precision electric grinder and engraving machine will generate a lot of dust during work, it needs to be cleaned frequently. The control box uses a hairdryer (opened in the cold wind gear) to face the heat dissipation hole to prevent dust accumulation.

How often do you need to replace the carbon brushes?

The working time of the mobile phone with a brush is about 500 hours. It is necessary to check whether the carbon brush has been worn out. If the carbon brush has consumed 2/3 of the length, the copper wire can be seen exposed in the center. The carbon brush must be replaced, otherwise, the rotor of the motor will increase wear, Directly affect the life of the motor.

How long can the bearings last?

The working mode of the handheld miniature high-precision electric grinding and engraving machine is high-speed rotation, so the bearing is consumable. Generally, the head bearing can work for 1000-1500 hours (different materials have different pressing forces and personal operating habits. Different sizes of dust particles produced by different processed materials have different hazards to the bearing)

What is the realization of bearing wear?

Generally, the noise emitted by the bearing will gradually become louder after the bearing is worn, the sound will become soft, and the beating degree of the shaft will also increase. At this time, you need to send a professional maintenance department to replace the bearing, otherwise, it will cause damage to other parts. The mobile phone has four bearings, two on the head, and two on the rear motor part. Because the force that it bears during work is on the head, the life of the two heads is shorter than that of the rear motor part, generally, the motor part bearing In contrast to the two in the head, the front one is more prone to damage than the back, generally about 1/3.

Micromotor vs flex shaft

flex shaft, economical electric grinders, and high-speed electric micromotor (tooth machines) can all control the speed by foot, but some models of the first two do not support it.

Generally, the flex shaft, up to several hundred watts, and is driven by a mechanical flexible shaft. Of course, the noise is also large, the speed is low, and the price is relatively cheap.

Economical electric grinders usually hold a 3mm handle, but there are also those that support drill chucks. They have low noise and generally have a power of several tens of watts. The functions of the two are the same, the accuracy is not high, and it is no problem to polish and engrave, and do some small things.

If possible, it is of course best to use a high-speed electric micromotor, also called a dental micromotor (used by a dental implanter), and the best one is brushless, almost no noise, high precision, and no vibration at tens of thousands of revolutions, due to the speed High, about 80 watts of power is enough, the polishing and engraving is very stable, the cutting efficiency is very high, the international standard blessing 2.35 mm handle, if you declare to be 3.0 when you buy it, the seller will replace it with a 3.0 three-lobed spring
