Tungsten steel cutting tools tend to accumulate cutting oil, grinding paste, tungsten fine powder and metal debris during grinding, before coating, or in regrinding and refurbishment processes. Fine contaminants hidden in cutting edge gaps are difficult to remove by manual wiping. The Bark ultrasonic cleaning machine is specially designed for tungsten steel cutting tools. It relies on ultrasonic cavitation effect to achieve all-round dead-angle-free cleaning of tools and guarantee stable cleanliness of cutting edges.

Before cleaning, clamp the tools properly and place them neatly in the cleaning basket to prevent collision damage to precision cutting edges, while ensuring the cleaning fluid fully flows through the tool flutes. Prepare cleaning media according to contamination types. Water-based detergent can be selected for heavy oil stains; modified alcohol or hydrocarbon solvent cleaning solutions are available for high-precision cleaning scenarios.

After starting the machine, ultrasound generates numerous tiny cavitation bubbles. Continuous bursting of these bubbles creates impact force to strip grinding dust and oil stains from tool surfaces, cutting edges and deep inside flutes. The cleaning duration is set based on contamination level; the main cleaning process normally finishes within several minutes. After main cleaning, the rinsing process removes stripped contaminants to avoid re-adhesion. Dehydration and drying follow rinsing to prevent oxidation and blackening of tungsten steel tools caused by residual moisture.

Sinobakr ultrasonic cleaning equipment supports fully automatic multi-tank processes for continuous batch processing of various tungsten steel tools such as end mills, drills and reamers. The whole controllable cleaning process will not corrode cemented carbide substrates or impair cutting edge precision. Compared with manual cleaning, it greatly improves efficiency and consistency of cleanliness.

In actual production, regularly monitor the concentration of cleaning fluid, filter metal powder in the tank timely and replace aging cleaning liquid to prevent dust reattachment. Widely adopted by tool manufacturers and reconditioning workshops, this process stably meets cleanliness requirements before tool coating and assembly, reduces coating defects resulting from poor cleaning, and improves the finished quality of tungsten steel cutting tools.
