This is exactly why ultrasonic deburring is receiving a lot more attention.
With this procedure, the portion to be deburred is submerged in a water bath, and a vibrating horn produces ultrasonic energy.
The resulting cavitation, along with the agitation of fine abrasive in water, has adequate power to kick off tiny burrs.
Key factors include workpiece material, transmission strength and frequency, and distance from the horn to the workpiece.
Using this technique, the part's surface finish can be easily varied.
Electro-chemical milling (ECM), which erodes metal to a preferred shape, may be changed to just deburr.
With this process, an electrolytic solution (water and specific salts) is pumped over the workpiece area, whereas a DC-current flows between the tool and also the workpiece.
The quantity of material taken out is determined by the power current flowing between the negatively charged tool as well as the positively charged workpiece.
Typical deburring and polishing periods are 10-30 sec for many pieces.
Substance removal amounts from.
0005 to.
01" (.

25 mm).
CoolPulse is a modification of the ECM process.
Average cycle periods fall into the 15 sec to 3 min variety, while small elements typically get less than 15 sec.
The process yields an even surface down to.
1 µm and there are also surface and cleanliness improvements.
The thermal-energy technique (TEM) utilizes extreme heat for deburring and/or deflashing.
Pieces to be processed are sealed in a pressurized cylindrical chamber along with a combination of a combustible gas and oxygen.
The gas mixture, when ignited, creates an intense, rapid burst of heat that uses up the burr and flash.
It is a rapid, low-cost, high-production procedure which removes burrs and flashing without affecting workpart surfaces.
An abrasive flow machine deburrs, polishes, or forms a radius on difficult-to-reach areas.
Two cylinders extrude an abrasive media back and forth through pathways formed by the workpiece and tooling.
Depending on the height and width of the burrs as well as the part's material, the actuating stress is between 7-200 bar.
Robots still control manual deburring operations.
They offer the advantages of increased precision, increased manufacturing volume, and general reduced expense.
Some of our scaled-down robots are made into OEM machines, but most of our sales are to those who already have an established deburring system, and want to boost it using a robot.
Typically the robot has a stand-alone support near the machine it's arranging, and may easily be shifted.
Vibratory Deburring Machines are genuinely beneficial.
Bigger equipment parts currently undergo wet vibratory finishing, which includes high density sharpening along with a liquid compound to assist dirt flotation, supply rust inhibition and produce a clear, vibrant finish.
A dry process and polishing technique is used to deburr the smaller gears, as they have an elaborate tooth profile.
Both machines are compact and quiet in operation, so we have had the opportunity to locate them in the main assembly area, which makes for optimum work flow and minimum interruption.
Slack and Parr's higher precision pumps are available in various variants, including planetary gear pumps as well as spin finish-metering pumps.
