About deburring and polishing

In the precision moulding and machining of electronic components and automotive parts, the removal of micro-particles that occur is a very important intelligence issue in product quality control. It is no exaggeration to say that it determines competitiveness. In particular, the retainer of a miniature bearing is a typical precision component with a complex and delicate shape that is not only difficult to deburr but also difficult to clean. The main conventional deburring method is parallel polishing, in which the retainer and compound are placed in a 1 cm stone (grinding stone) called a media and rotated for 30 minutes to one hour to deburr and polish the retainer. The stone and retainer are then separated, and the retainer is cleaned in an ultrasonic cleaner and dried. This process is extremely hard work and the working environment is harsh, making it extremely difficult to recruit young workers. It is also difficult to ensure consistent quality.

This ultrasonic deburring and polishing enema cleaning device is a fully automatic device developed for one retainer. All you have to do is put between 1,000 and 25,000 retainers in the basket, close the lid and press the switch.
At present, it has only been put into practical use for retainers, but the principle is expected to be applied to a wide range of small skillet processing products other than retainers.

Performance of deburring and polishing

The retainer rotates slowly and is subjected to the shock waves and vibrations of the powerful capitee, while deburring, grinding and cleaning are carried out at the same time.
Hexagonal rotary cages sent from the inlet conveyor are ‘Roughly polished to remove burrs’ in the first stage, ‘Finish polished to remove burrs and washed’ in the second stage, dried in the third and fourth stages, and then come out from the outlet conveyor.
This process differs from conventional barrel polishing – ultrasonic cleaning, which is all carried out automatically.

Principle

Powerful ultrasonic waves are irradiated into water in which dissolved air has been sufficiently removed to generate a myriad of spherical nebula-shaped microvacuum nuclei (capiti). When those vacuum nuclei are generated and annihilated, positive and negative impact forces are generated, Paris is removed and the vibration is sharpened by the noise.
Targets include miniature bearing retainers and equivalent precision machined and precision moulded parts. The system uses powerful 25 KHz ultrasonic waves with various ultrasonic frequencies up to 275 KHz and simultaneous multiple-wave oscillation to generate shock waves from cavities (groups of micro vacuum nuclei) to deburr, clean and dry workpieces placed in a hexagonal rotating basket.
The ultrasonic output is 2400 W for both the first and second cassettes, and only water is used, without any abrasive materials.
