Benefits of technology
The present invention is a grinding apparatus that includes a connecting shaft, a media holder, and a media plate. The media plate can be removably attached to the bottom of the media holder and includes a lower surface with grinding, abrasive, or polishing media. The media holder is pivotally coupled to the connecting shaft and can be attached to a platform plate using brackets and a slot. The grinding assembly also includes a slot for easy attachment of a media plate. The apparatus can be used with a powered rotary surfacing machine for polishing substrate surfaces. The technical effects of the invention include improved grinding efficiency, flexibility in attachment of a media plate, and ease of use with a powered rotary surfacing machine.
Problems solved by technology
Currently the process of polishing concrete requires a great deal of expertise and the use of specialized heavy-duty machines and tooling.
The machines currently available in the art are very expensive and labor intensive to use.
Moreover, they are very heavy to move especially on multi-floor construction projects where elevators or winches are required.
Due to the high investment cost some contractors have turned to offering a topical polished surface versus the full grind process.
This method may look impressive when initially completed, but is inferior in most situations when one considers that one of the weakest parts of a concrete slab is the surface.
Some coating materials do not allow moisture to escape from the concrete, resulting in a buildup of hydrostatic pressure that could delaminate the surfaces and or wear off prematurely requiring additional applications of expensive coatings.

Embodiment Construction
[0028]The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
[0029]Broadly, an embodiment of the present invention provides a grinding disk platform that has a plurality of grinding disk assemblies disposed on the disk platform. According to other aspects of the invention, the grinding disk platform is adapted to be readily attachable to a standard concrete leveling trowel. In other aspects of the invention, the grinding disk assemblies are attached to the disk platform so that a grinding media carried by the assemblies may be maintained in a substantially coplanar orientation with a concrete surface.
[0030]An object of the invention is to use a common platform technology i.e. a common set...

Abstract
A grinding disk, surfacing platform, apparatus and method adaptable to a rotary concrete surfacing machine. A media disk is pivotally attached to a surfacing platform to maintain a substantially coplanar alignment of an abrasive or polishing media surface and the underlying substrate to be polished. The surfacing platform engages with rotating arms of the machine in operation and may be readily be detached by rotating in the opposite direction of operation.
Description
CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of priority of U.S. provisional application No. 62 / 081,895, filed Nov. 19, 2014, the contents of which are herein incorporated by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to the construction industry, particularly in the area of providing a finish to concrete floors within a building or other structure. More particularly, the present invention relates to a grinding disk platform that uses platform-sharing technology to create an apparatus that can produce a full grind polished finish on concrete floors.[0003]For homeowners, retailers, architects and engineers that are choosing polished concrete as a finished floor of choice, aesthetics', uniqueness, ease of maintenance and light reflectivity are a few reasons why this flooring system is quickly becoming one of the most popular and sought after hard surface floor.[0004]Currently the process of polishing concrete requires a ...
