Technical Solutions

Marshall Machinery provides technical support and equipment to help your company become more productive in the following areas:

Inspection and Measurement

The following is more information about all of these areas, along with some definitions of the common terms used.

Terms

Abrasive Blasting

Abrasive blasting (sometimes called sandblasting) is the operation of cleaning or preparing a surface by forcibly propelling a stream of abrasive material against it. Common abrasives used are glass bead, aluminum oxide, silicon carbide, or garnet.

Belt Grinders

Belt grinders are machines used for a number of purposes. They can be used to grind down material for burr removal, to create a surface finish, prep a surface for coating, etc. Industry known and respected, Burr King offers commercial-duty abrasive grinding systems to meet every customers needs.

Centrifugal Disk & Bowls

Centrifugal part finishing offers a higher energy deburring and polishing process that allows you to mass finish your parts in a shorter time than when using a standard vibratory bowl.

In Centrifugal Barrel Finishing (CBF), operators place parts and media into a closed barrel attached to a processing turret. As the turret rotates at high speed, the barrels counter-spin against the turret's rotation. This action delivers the centrifugal force.

In Centrifugal Disc Finishing (CDF), a round rotating disc is at the bottom of a round stationary chamber. When the machine is energized the disc's rotation forces the entire mass to rise quickly upward and outward. The walls of the upper processing chamber slow the mass, effectively "braking" it, turning it over upon itself to tumble down and inward, back to the disc to begin again. The mix takes the shape of a vortex of parts, water and media. The centrifugal force developed by the disc adds weight to the parts and media. The result is a highly aggressive parts-finishing energy.

Deburring

Deburring is the removal of burrs on a part by processes such as blasting, mass finishing, tumbling, vibratory tumbling, or grinding.

Lean Mfg

Lean Manufacturing, which is often known simply as "Lean", is an operational strategy oriented toward achieving the shortest possible cycle time by eliminating waste. Derived from the Toyota Production System, this strategy helps decrease the time between a customer’s order and shipment. It is designed to radically improve profitability, customer satisfaction, throughput time, and employee morale. Benefits include: lower costs, higher quality, and shorter lead times. Marshall Machinery can help your company’s lean initiative by integrating lean workspace design options that help meet your goals.

Vibratory Bowls

Vibratory bowls offer a means of deburring and/or polishing a number of parts at the same time. The processing chamber is the shape of a hollowed doughnut lying on its side. A motor is attached to a shaft with eccentric weights which is fixed to the bowl-shaped chamber which is suspended on springs. The ensuing action causes the mass to travel in a three dimensional, toroidal motion. This type of action allows for the most efficient processing of work pieces. The work chamber can almost be filled to capacity, as well as allowing a high concentration of work pieces in relation to the mass.
