Floor burnisher is the term for a high speed floor buffer that rotates its pad at over 1000 RPM. Closely resembling a large upright, wide-based vacuum cleaner with handlebar controls and requiring two-handed steering by beginners, a floor buffer uses one or more variable-speed circular rotary brushes to dislodge dirt and dust from and apply a ...
The company was founded in Minneapolis by George H. Tennant as a wood-working business in 1870. [2] It was incorporated in 1909. [3] Tennant is the U.S. market leader in cleaning equipment. [4] In 2017, Tennant announced the acquisition of IPC Group, a company based in Italy manufacturing cleaning machines. [5]
Purpose-manufactured burnishers are polished smooth, typically made from high speed steel (HSS) or cemented carbide, [4] and usually have wooden handles. The shaft profile is usually round, but other profiles include oval and triangular.
A propane burnisher is a type of rotary floor burnisher, a floor buffing (polishing) device, that is powered by propane. It is designed to rotate in speeds in excess of 1200-1800 RPM . It typically has a series of interchangeable pads that promote the cleaning, along with different types of abrasives and solvents available to buff the floor to ...
The tooling is pressed into the surface of the part while it is rotated (in some applications, the tools are rotated instead of the part). The burnishing tool rolls against the surface of the part at a constant speed, producing a very consistent finish across the part. A surface finish of less than Ra 0.1 μm is achievable with roller ...
The plastic deformation associated with burnishing creates greater heat and friction than from rubbing alone. This reduces the efficiency of the machine and limits its speed. Furthermore, plastic deformation alters the form and geometry of the part. This reduces the precision and accuracy of the machine.
