Advancing Precision Manufacturing: Conprofe Ultrasonic’s Rotary Ultrasonic Machining Innovation

In the realm of precision machining, Conprofe Ultrasonic has emerged as a trailblazer by seamlessly integrating Ultrasonic Machining Technology and green technology. Their revolutionary rotary ultrasonic machining system breaks through the processing challenges posed by hard and brittle materials, hard-to-cut metal materials, and composite materials.

Rotary Ultrasonic Machining

Conprofe Ultrasonic’s rotary ultrasonic machining is a groundbreaking technique that combines the power of ultrasonic vibrations and rotational motion to achieve unparalleled precision. The machining process involves the use of a rotating tool that generates high-frequency mechanical vibrations (18~70 kHz). These vibrations, converted from ultrasonic electrical oscillations, are applied to the cutting tool as it rotates against the workpiece surface.

Advantages of Rotary Ultrasonic Machining

  1. Enhanced Precision and Surface Quality: The combination of ultrasonic vibrations and rotational motion ensures exceptional accuracy and surface finish. With a minimum flute width of 0.01mm and tool profile accuracy within 3μm, Conprofe’s self-developed Solid PCD Micro-Edge Cutting Tool delivers mirror-like finishes and superior workpiece surface quality.
  2. Prolonged Tool Life: The unique flute design of the Solid PCD Micro-Edge Cutting Tool enhances tool rigidity and sharpness, resulting in a tool life improvement of 3-8 times compared to imported PCD-coated cutting tools. This longevity translates to cost savings and increased productivity.
  3. Reduced Cutting Forces and Temperatures: The application of ultrasonic vibrations effectively reduces main cutting forces and cutting temperatures. This reduction minimizes subsurface damage and machining stress, particularly in hard and brittle materials, resulting in improved workpiece integrity.
  4. Superior Lubrication with Minimum Quantity Lubrication (MQL): The rotary ultrasonic machining system incorporates Minimum Quantity Lubrication (MQL) technology, which atomizes lubricants into ultra-tiny mist particles (5-30μm). This lubrication barrier between the workpiece and the tool reduces friction and heat during machining, leading to improved lubrication efficiency and extended tool life.
  5. Supercritical CO2 Cooling Integration: To further enhance cooling and lubrication, Conprofe Ultrasonic’s rotary ultrasonic machining system seamlessly integrates Supercritical CO2 Cooling Technology. By converting low-pressure CO2 air into supercritical CO2 fluid and injecting it into the cutting area, the system achieves efficient cooling and rapid chip evacuation.


Conprofe Ultrasonic’s rotary ultrasonic machining technology represents a groundbreaking advancement in precision machining. By harnessing the power of ultrasonic vibrations, rotational motion, Minimum Quantity Lubrication (MQL), and Supercritical CO2 Cooling Technology, Conprofe Ultrasonic has revolutionized the industry.
