Reduced stepping motor deburring personnel by 100 people

In recent years, in a strong demand for higher efficiency of motors, and for permanent magnet materials that greatly affect their performance, in addition to improving the magnet performance itself, it has become important to improve its complex shape, heat resistance, and environmental friendliness.  As an effective magnet for complication of shape, there is a rare earth magnet that can form a complicated shape by solidifying neodymium (Nd-Fe-B) with a resin (PPS40%).

 One of the issues in this case is the burr that occurs due to the pursuit of complicated shapes, although the solution tends to be procrastinated. It cannot be a product unless burrs are removed and cleaning.

Similarly, THRUST-BEARING (PPS-CF30%) used for the same stepping motor is the same, and even with excellent molding technology, burrs cannot be completely removed, so it is necessary to remove burrs in the mass production finishing process.

Existing methods for removing burrs from these cannot accommodate the mass production of precision parts such as stepping motors.

Blue Star R&D irradiates powerful ultrasonic waves in water, and if it is ROTOR of (Nd-Fe-B + PPS), 200 to 300 pieces in 5 minutes. With THRUST-BEARING (PPS-CF30%), more than 5000 burrs can be removed and cleaned in 5 minutes. Of course, it is easy to dry. With a production line of 1 million pieces, it can be said that it will be possible to reduce the number of deburring personnel by 100 people. The cost reduction effect is also great.

Blue Star R&D can contribute to technological progress with environmentally friendly and the world’s only one ultrasonic deburring technology .

Ultrasonic deburring, cleaning and polishing machine for spring/ abrasives unnecessary and what necessary is only water

A high-speed ultrasonic barrel finishing machine for precision parts that can be replaced conventional barrel finishing machines. This is a dream machine for deburring, polishing, cleaning, and simultaneous processing without abrasives.

Only various springs are set in a rotating hexagonal basket, and strong ultrasonic waves are emitted from the outside of the basket.

This is a deburring and polishing device for springs that utilizes positive and negative impact forces when cavities (microscopic vacuum nuclei) are generated and extinguished, and the deburring and polishing effects of ultrasonic vibration.

Various leaf springs, springs, and processing of sizes from 0.5mm to 100mm can be processed at once. Possible process amount at once is 1,000 to 100,000.

Unlike existing deburring machines, abrasives such as stones and needles doesn’t necessary.

Ultrasonic deburring and polishing machine, which only need water and ultrasonic, can process much faster than conventional deburring using method.

Difference between ultrasonic barrel polishing and conventional barrel polishing

No abrasives needed. What necessary is just water and ultrasonic.

・The work of separating from abrasives is unnecessary.

· Defects due to media jams do not occur.

· No need to replace or control abrasives.

· Since there is no abrasives, you are freed from heavy labor.

The deburring and polishing speed is on average several times faster than existing barrels.

At the same time, precision cleaning is possible, and it can also be used for electronic parts with complicated shapes that cannot be soiled.

Wastewater treatment is unnecessary.

In addition to city water, pure water, rust inhibitors, and hydrocarbon solvents (S type) can also be used.

Drying is easy, and full automation can be easily achieved.

Reduce labor costs, stabilize quality, and increase production efficiency.

Full automation of deburring, polishing and drying is also possible.

Introduction of ultrasonic barrel polishing technology that does not use abrasive compound

As the delivery record of ultrasonic barrel equipment (deburring, polishing, cleaning, simultaneous processing) increases, the number of inquiries and test requests to our company has been increasing rapidly.

The ultrasonic barrel does not use abrasive compound. A large amount of parts are put directly into a hexagonal  basket and process to deburr, polish and clean them while irradiating them with ultrasonic waves for deburring.

Objects are various metals, plastics, ceramics, etc. It differs from traditional barrels in the following points.

【Features】

1・ Since it does not use media, many ultrasonic barrel operations are light work.

2., It can be achieved higher quality in a short time than existing barrel polishing. (Depending on the shape and material of the product)

3. Precision cleaning is possible.

4. Wastewater treatment is basically unnecessary.

5. Easy to dry.

6. Automate for deburring (polishing)→Drying.

As a result, labor costs, man-hours can be significantly reduced, quality can be improved, and major environmental improvement measures can be taken.

Blue Star R & D is accepting ultrasonic barrels test.

We have the world-only technology.

Metal 3D molding /Complete removal of internal fine powder by powerful ultrasonic

Complete removal of internal fine powder by powerful ultrasonic

The development of metal 3D precision molding technology is remarkable, and it seems that it has been evolving more precisely, more complicatedly, smaller and smaller.

On the other hand, what is important is the fine metal powder left behind inside. If this is not removed, the product will not be completed.

Blue Star R & D’s ultrasonic waves completely clean and remove the metal dust inside. The powerful ultrasonic waves that can remove even burrs are sufficiently transmitted to the inside when irradiated from the outside of the metal 3D molded product, and clean the metal fine powder remaining in the internal flow path.

If you have any problems, please feel free to contact us.

You can check by our test.
