  • Ultrasonic Generator to produced high-Frequency Electrical Energy operating at a frequency of 20KHZ and Ultrasonic Power of 120W
  • S.S. Velocity Horn fitted with PZT Crystals (Transducer Elements).

The Velocity Horn assembly converts the electrical high-frequency energy fed from the Ultrasonic generator to mechanical vibrations at the rate of applied electrical frequency. The amplitude of these mechanical vibrations is magnified by this Velocity Horn. This Velocity Horn is used for the processing application.

This CNC mister oves from machine to machine without production delays. Hand-carry this versatile lubricator from one scheduled cutting or machining equipment to the next. A heavy-duty magnet lets you install it with minimal downtime.

Oil mist lubrication system roduces a continuous output of precisely metered lubricants. Air-driven, positive-displacement pumps precisely meter each drop of lubricant at .03 cc/stroke. The 100-million cycle pulse generator allows for automatic, infinite repeat cycling of the metering pump. This ensures that a continuous, external film of lubricant is applied to the tool-work interface.

Lets operator easily control atomization of the spray by adjusting air, pulse per minute and liquid metering.

Adjusts output from 4-200 injection cycles per minute with 0.1 to 3.0 drops of lubricant per cycle. A durable, vented 16 oz. reservoir on the CNC mister holds more than 14,400 drops of lubricant.

Dispenses any highly refined lubricant including Unist’s high-efficiency Coolube® from the oil mist lubrication system's durable, 16 oz. (0.5 L) vented reservoir.

The CNC mister combines lubricant and air in the patented Co-Axial Nozzle tip. The oil mist lubrication system keeps atomization and distribution of the liquid consistent regardless of the hose length. Plastic 12 in. nozzle is coupled with 5 ft. Co-Axial hose. A heavy-duty magnetic base at the hose/nozzle connection of the oil mist lubrication system makes it easier to relocate and position the nozzle at the friction points.
