Often the only setup required is changing the bed opening (for different part thicknesses), and this can be done in a matter of seconds. Sometimes the setup requires changing an abrasive belt for a different finish, and this usually can be accomplished in less than three minutes. Occasionally an operator may need to change out a barrel brush, but this typically takes less than an 15 minutes.
In most cases, however, cut parts simply undergo deburring and then flow consistently to downstream processes. With the right type of machine and abrasives, automated deburring may seem almost invisible. It just works, with little fuss.
Some upfront work required to determine the proper configuration includes weighing all the factors—wet versus dry; number of heads; abrasive media type; part feed and abrasive rotation speed; the parts themselves, including size, material grade, and thickness; and the grain finish desired. At best, automated deburring makes a relatively inconsistent manual process much more predictable and reliable. Often this initially requires trials using several different options. Once that configuration is defined, however, operating an automated grinding machine is simple and cost-effective. For a fabricator’s primary cutting operation, this can be a very good thing.
You can drastically improve the efficiency by using our Profimach deburring machines compared with hand work.
How the machine holds the workpieces in place factors into the equation when choosing which abrasive belts and brushes to use. For instance, if small parts are conveyed on a conventional conveyor belt, abrasive heads may cause parts to slip, resulting in inadequate deburring or finishing action. The abrasive head may even pick up or throw the slipped part, potentially damaging the machine.
In many situations, the part length must be at least equal to the distance between the pinch rolls, so there is always at least one pinch roll holding the part against the conveyor belt. Part thickness plays a role here too. A part’s length or width should be large enough in relation to its thickness to prevent the part from tipping during the grinding process.
For parts shorter than the distance between the pinch rolls, there are some options. For deburring extremely small parts, processing a group tabbed into place in a skeleton can work well. Of course, breaking the tabs to remove the parts may leave small burrs or marks, which may require further manual grinding if they are severe enough. In some cases, fixtures can hold parts in place during deburring, though such fixtures must be designed for each part or part family.
A vacuum bed is another option. This is a conveyor belt with small holes and a blower. The blower draws air through the holes and the machine bed, creating enough vacuum pressure to keep small parts stationary during grinding. If a small part can be held with a magnet, some machines also may be fitted with a magnetic chuck. As another workholding alternative, a deburring system with a sticky conveyor belt may be able to hold small parts in place throughout the process. As always, the workholding method depends on the application.
