New Advanced Developed 20KHz Non-contact Ultrasonic Assisted Machining Device

Ultrasonic assisted drilling technology is a drilling technology with a feed direction of 2-20°. The drill uses high frequency vibration (>20 kHz) to improve processing conditions and productivity.

Ultrasonic vibration can not only reduce the thrust, but also improve the surface quality of the hole. In addition, high-frequency vibration has no significant effect on the dimensional accuracy or microstructure of the borehole.

Ultrasonic assisted drilling technology is a technology that applies ultrasonic vibration in the feed direction of the drill bit to improve drilling conditions and productivity. UAD is superior to traditional drilling technology in reducing thrust and torque, reducing burr height, and improving surface roughness and hole accuracy.

The precision and surface quality of the finished product are important factors for the final product, especially in many drilling processes. Burrs are generally considered to be a negative result of the assembly process. One way to reduce or remove metal cutting burrs and improve surface roughness is to use ultrasonic vibration during drilling. Ultrasonic assisted drilling (UAD) is a promising method for machining hard, brittle and ductile materials. It is used to manufacture parts with high-precision features, including optical, dental and electronic products. The evaluation of cutting force is very important because it directly affects the power consumption, tool life, dimensional accuracy and surface integrity of the machined parts. The cutting force in UAD is smaller than that in CD. In UAD, the cutting force is directly affected by the cutting conditions (such as ultrasonic frequency and amplitude). In addition, the characteristics of the part material (such as hardness and fracture toughness) will affect the processing behavior.

Combined with a unique plug-and-play module type design and innovative contactless power transmission technology, SP Tech Ultrasonic Machining modules are flexible and can be easily side-added to a variety of CNC machine tools, such as milling machines, drill presses and even robotic arms.

Introducing new technology doesn't have to take a lot of time or money.

Our modules allow manufacturers to go into production in one day without having to buy a whole, expensive and bulky machine.

Since the ultrasonic handles contains electronic components, the power transmission method has become an essential part of the technology. SP TECH ultrasonic machining tool holder module utilizes the non-contact power transmission technology to transmit the electric power on the high-speed rotating tool. A patented precision actuation mechanism inside the tool holder then generates a high-frequency micro-vibration on the cutting tool edge. Neither consumables nor friction which causes tool wear do you need to worry, removing the limitation of the high spindle rotation speed advantage. Which achieves a win-win effect of stable and efficient production. 

Ultrasonic assisted machining can process surfaces of various shapes, such as planes and grooves. Used for ultrasonic milling, cutting, grinding and other machining. The device is suitable for turning, milling, drilling and grinding of diamond, glass, ceramics, tungsten carbide, titanium alloy and other materials. Compared with other processing methods, it has the advantages of low cost, high precision and no need to change the machine tool.
