Working principle:

YUETAI Mini Ultrasonic Grinding Machines have the function of power automation compensation, the frequency automation tracking lock, and it can use the various tip implements at more than 20,000 times per second. Maximal amplitude is 50 um, high speed. Brute force and stable grinding work piece surface can ensure that the implement is in the best syntony state at any time, and ensure stable power size on certain job requests. Deploying varieties tip implement head can complete rapidly different hardness materials of complicate cavity such as plastic injection mould, casting mould, forged mould.

Main Specialties:

2.Ultrasonic circuit control adopts mirco-computer single chip control technology design.Its lock efficiency cincture is wider and more precise.And for work pieces with different shape,it has a fine adaptability to make sure that it works on the best working frequency range and biggest ultrasonic amplitude,especially fibre stone and so on material-consuming fitting ,whose grinding effect is best.

3.The panel operating part uses high-qulity PVC panelintelligent adjustment full light tough electronic switch and has characteristies of dust proofwater proofcomfortable handle and good-lookingsimple operationdifficult to aging and difficult to damage.

4.The control panel adopts two-number display,separately show regulating power and output power;When opening the machine,it has the displaying function of work time accumulative total,the most accumulative total shows 99 months,which makes enterprise follow and manage usersusing condition very efficienly.

5.The spark circuit adopts presently international most advanced digit spark corrosion circuit, changes from three levels to four levels,which more adapts to coarsenessly machine original coarseness surface after machining presently market popular machine-machining equipment(such as electrical impulseline cuttingmilling machineand lathe) It has characteristies of wide rangehigh precisionquicjly cutting big peeling-off electrical corrosion.It also machines complex cavity which is not machined by handcraft,such as deep channelnarrow grooveblind holecircle slot and acute angle.When the machine polishs with ultrasonic it can finish whole polishing andand grinding process from coarsenessly polishing,extractly polishing to mirror surface for original surface roughness Ra>50um.

Application scope:metal workpiecegrinding and polishing,such as the note modethe die-casting modethe pressing modethe forging modehardwear product

Operate attentive matters:

1. When start the power, need to join the good cable and operate handles and can turn on the apparatus first, can put through the power

2. When regulate and establish the ultrasonic power, need to lock the amplitude pole of transducer and high level tools (consumptive material) at first. Then the power enactment reveals “green”( max.is " nine " section),the power output state shows “red”(max.is “nine”section); If the power enactment already reveals to be " 9 " section, the red lock shining indicator light inside the pannel of machine case has also lockde to lighten,and the ultrasonic power output is still on the weak, then you should pay attention to little adjust length or shape or angle in order to reach perfect power output state(best swing )

3. When open the electrical spark and corrosion function button, need to join the ground wire between the electrical spark export and the work piece. When the electrical spark and corrosion enactment shows “four”(max.section),the bigger the number,the more quick the electrical corrosion,but the bigger the surface coarsene after processing.If the electric spark and corrosion enactment has already opened,the red sgining indicator lamp of “1-4”any section lights,but the electrical corrosion does not still export or is weak,then you need to check if the ground wire of the electric spark output and the work piece contact well or check the electricity-transmiting performance of the spark corrosion’s cooling fluid.

Ultrasonic output is weak : check ultrasonic power regulation but  ton and amplitude pole  ( if it is screwed down and regulate vibrating spear’s  length or its angle)
