Deburring Tools

Deburring tools remove flashing and other unwanted edge properties caused by cutting or machining. Deburring equipment removes burrs, smoothens parting lines, jagged edges, or protuberances on the surfaces of an object created during machining or casting operations. A deburring machine offers the fastest processing times and the highest reliability percentages leaving little scope for errors and inconsistency to remove burrs from a work piece. A deburring tool greatly improves the quality and functionality of metal and wood pieces, making it a necessary use of time and a cost effective process. Deburring tools include many different types of process such as thermal deburring, chemical deburring, and vibratory deburring. Chemical deburring (ECD) utilizes electrical energy which is directed to only specified areas on the part to remove burrs. Thermal deburring uses instantaneous and very intense heat energy to perform a deburring operation. Vibratory deburring has a thick cast polyurethane liner caster for easy mobility and a sound abatement cover. It is either alumina or silicon carbide based with varying degrees of abrasive or polishing material depending upon the application. Different types of deburring tools are commonly available.

There are several ways in which deburring tools function. It involves localization of electrical energy by means of a fixture/electrode, which conforms to the configuration of the finished area. The energy is transmitted to the burr by an electrolyte chemical and then it dissolves it. The controlled radius is generated as the burr is dissolved and can solve functional problem. In thermal deburring, parts are placed inside a cylindrical chamber, which is sealed. It is then pressurized with a mixture of combustible gases, which reaches even to the most confined areas. When the gaseous mixture is ignited, an intense combustion takes place generating a very intense heat lasting only a few milliseconds, removing only the burrs. A deburring brush is frequently combined with upstream processes to reduce overall process complexity and cost. They are specifically designed to provide maximum cleaning or oxide removal for circuit board manufacturers and metal finishers. Deburring tools feature a straight, angled, or multiple-position head that accepts standard-sized burrs.

Deburring tools are used in many applications. Examples include their use in zinc die castings, aluminum die castings, screw machine parts, hydraulic valves, pneumatic valves, forgings, and instrumentation. Deburring tools are ideal for small castings, surface finishing, precision stampings, forging and better finish. Deburring machines are designed for light deburring, polishing and cleaning small, light precision parts. They are suitable for all types of materials such as brass, steel, stainless steel, zinc, cast iron, thermoplastics, platinum, and aluminum, hard plastic, copper, gold, and silver. Deburring tools should adhere to International Standards Organization (ISO) and Institute of Electrical and Electronics Engineers (IEEE) standards.
