Ultrasonic wave is applied to the grinding and polishing of diamond and synthetic diamond drawing dies. This new technology has been widely used at home and abroad. The processing speed and product quality of ultrasonic wave grinding and polishing have been greatly improved.
Upm-150 oil return type ultrasonic lapping machine is used to repaint and repolish diamond and synthetic diamond drawing dies in the range of 0.1 to 3.0 mm.
The major improvement of this machine is: there is a turntable automatic control mechanism, the generator uses transistor to improve the power output. The t-meter of ultrasonic transducer is improved. Direct air cooling, upgrading on the basis of ordinary oil pressure, patented products, solve the oil leakage problem of oil cylinder working for a long time, better maintain the stability of oil pressure, improve the production environment.

3. Working principle and equipment composition

1. This machine uses ultrasonic high-speed vibration to produce impact on the machined surface through steel needle and die material, grinding the machined surface to achieve the required shape and size.
2. The equipment is mainly composed of ultrasonic generator, transducer and base.
(1) Ultrasonic generator
The ultrasonic generator is installed in a small cabinet, which is an ultrasonic power supply. The frequency automatic tracking circuit is used to achieve the best ultrasonic output and vibration effect.
(2) Transducer
The transducer is a high-efficiency piezoelectric ceramic transducer, which can convert the ultrasonic wave into a stable ultrasonic vibration and is air-cooled.
(3) Stand
The machine base has a rotatable and swinging mold base, which is installed on a cross carriage, and moves up and down flexibly through hydraulic vibration and weight pressure. The cross carriage can be freely aligned with the center. There is a carriage that can move up and down on the back column, and the transducer is installed on the carriage.

4. Installation and use

1. Installation
Place the base on a stable table, move the transducer up and down, adjust it to a proper position and lock it. Connect the ultrasonic generator with the transducer with the output line provided with the machine, then insert the hair source plug on the base into the power output socket of the ultrasonic sounder, and inject 10? Oil into the oil cup for inspection When the switches are off, plug the power plug of ultrasonic generator into the power socket with reliable grounding.
2. Use
According to the size of the processing mold, select the appropriate horn and steel needle, firmly weld the steel needle to the horn with silver or copper welding, cut the appropriate angle on the grinding wheel, install it on the transducer and tighten it, put the mold on the mold base, adjust the cross carriage and the upper and lower carriage of the transducer, make the steel needle insert into the mold hole, adjust the rank code pressure, then put in the mold material, turn on the ultrasonic power and turn on the switch If necessary, turn on the swing switch of the mold base, adjust the ultrasonic output power knob to an appropriate size, and then it can be seen that the mold material is stirred under the ultrasonic, that is, the mold processing is in progress.
Note: if necessary, adjust the frequency fine-tuning to optimize the power output
