This all-new model is fully self-tuning which means once you have properly attached the tool, you turn it on and adjust the power for the material you are machining.

This ultrasonic drill is designed to drill .5mm-4.0mm holes, engrave (with a solid die) up to 8mm, and cut hard brittle materials by using ultrasonic energy. It will drill through precious stones, semi-precious stones, ferrite, silicon, glass, and ceramics. This is completed by the solid-state transducer transforming A/C current into mechanical vibration of about 20 KHz per second. Feed the 220g graded silicon carbide abrasive onto the tool and work piece to drill or grind the your piece, forming a hole that is the same shape as the tool.
Ultrasonic cutting is fast and clean. It usually outperforms diamond drilling tools and the consumable items are more cost effective. For example, a diamond-plated drill usually costs between $1.00 and $5.50 and will last from 1/2 hole to 2-3 holes. The drill tube for the ultrasonic costs from $.08 to $.24 each and lasts for 10-20 holes in agate and 50-100 holes in glass. A 1.0mm hole can be cut in an agate slab of 4.0mm thick in about 60 seconds. The same can be done to glass in about 15 seconds.
This machine comes with 5 horns, a propane torch, flux, silver solder, tools, spare fuses, 5 lbs. of 220g graded silicon carbide, a pump and water manifold. In addition you will receive 10 meters ( 25 tubes per meter) of the sizes of your choice. The tubes come in .5mm, .8mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, and 5.0mm. Additional quantities of tube are available for purchase.
The drill press option allows a vertical movement of about 1" ( 28mm) for controlled drilling into the workpiece. This tight sliding vertical movement allows you to mount your material in a fixture to get controlled drilling for beads and other products. It is especially useful when there is a need to drill from both sides. This option can be ordered with the machine or can be added to existing lud-200 machines. The option consists of the slide assembly, and new extended mast. The same transducer shield is used but a new hole must be drilled for the eye for the arm to be installed.
*These high-quality ultrasonic drills are imported from Taiwan. They have been counted as the most reliable ultrasonic on the market for the last 25 years.*

In summary, an ultrasonic drill can work by the "jackhammer" motion of a free floating mass, or by the transfer of the ultrasonic frequency to an abrasive slurry. The best "bit" appears to be a hollow metal cylinder that is soldered to the small end of a horn. The ultrasonic driver needed is rated at 28 KHz and can be found for $30 on Ebay. Another component needed is the transducer, which can be found for $40. When trying to match the resonant frequencies, it is important to take into account that transducers rated at 28 KHz might be off by 0.5 KHz. The author has a way to measure the impedance and tune the frequency

I'm attempting to build an ultrasonic drill to make holes in silicon wafers, since we don't have the budget to buy one in our lab. From what (I think) I know, ultrasonic drills can either work by the "jackhammer" motion of a free floating mass which I don't know how to make, or by the transfer of the ultrasonic frequency to an abrasive slurry. I want to make the latter type.From what I gathered online, I think I'll need the following components:1) Piezoelectric transducer. I found a 70W transducer that works at 28 KHz for about $40.2) Horn. This transfers the vibrations from the transducer to the drill bit. I'm planning to have a "step horn" milled for me at our machine shop out of aluminum. This type amplifies the vibrations. Its length is critical to reduce the impedence, and should be roughly half a wavelength long as a general rule of thumb.3) Drill bit. For the 1 mm holes I'm planning to drill, the best "bit" appears to be a hollow metal cylinder that I can solder to the small end of the horn.4) Ultrasonic driver. My electronics knowledge is very limited, so I'm planning to just buy one off Ebay for $30. I found a 60W, 28 KHz driver that works for 110V.What I'm worried about most is matching the resonant frequencies. I'm trying to follow this instructional the best I can:. Apparently, transducers that are rated at 28 KHz might be off by like 0.5 KHz, and this small difference can have a huge effect on the impedance as you can see from the plots on this website. The author apparently has a way to measure the impedance and tune the frequency so that the impedance is minimized. If I buy the 28 KHz driver (the author built their own), what's the cheapest thing I can buy that will let me tune this up and down, and measure the impedance?Also, when I look up the wavelength of a 28 KHz wave (), I see numbers like meters for half a wavelength. However, the author's horn is only 95 mm long. Clearly, there's something about waves I don't understand and I would appreciate any answers for this discrepancy.

You will get efficient and thoughtful service from Nekon.
Do you guys think this topic is better off in the electrical engineering forums? It's a combination of mechanical, electrical, and physics so I wasn't quite sure where to post it.

Try calculating the wavelength for sound, rather than light.
K_Mitchell
Did that and found the number was still an order of magnitude off. Then I realized this value was through air rather than aluminum. When the speed of sound through aluminum was used, I got the correct value. Thanks! I also found an excellent paper on horn engineering with easy to perform calculations.
Still need help with finding what I can use for fine-tuning the frequency and measuring the impedance.
An ultrasonic drill uses high-frequency vibrations to break apart material. The drill tip vibrates at a frequency of around 20,000 times per second, creating tiny cracks and fractures in the material. This allows the drill to easily penetrate and remove material without exerting much force.
An ultrasonic drill can be used on a variety of materials, including metals, ceramics, and even delicate materials like glass and semiconductors. However, the effectiveness of the drill may vary depending on the hardness and density of the material.
One major advantage of an ultrasonic drill is its ability to create precise and clean cuts without causing damage to the surrounding material. It also produces less heat and noise compared to traditional drills, making it a safer and more efficient option for drilling.
An ultrasonic drill uses high-frequency vibrations to break apart material, while a traditional drill relies on rotating motion to penetrate material. This makes an ultrasonic drill more suitable for delicate materials and creates less friction, resulting in less wear and tear on the drill bit.
Yes, an ultrasonic drill can be used for industrial purposes, especially in precision industries such as aerospace and medical manufacturing. Its ability to create precise and clean cuts makes it a valuable tool for these types of industries.
