Low pressure polishing method and apparatus
An improved low pressure low speed concrete polishing apparatus and method of cleaning and polishing a floor is used with a conventional rotary flooring machine. A polishing pad has interchangeable polymer strips that are slideably received within the housing of the pad. The polymer strips have an abrasive material embedded therein which collectively work to polish the floor while cleaning the floor during normal low speed floor cleaning conditions.
1. An abrasive cleaning device for modifying the surface of a floor comprising:
a rotatable housing that is operable to be connected to a cleaning machine, the housing having a plurality of slots; and
a polymer strip operable to be received within each of said slots, said strip having an abrasive portion and a connection portion, wherein the abrasive portion of said polymer strip includes a metal section, a coating over the metal section and abrasive particles protruding from the coating.
2. The abrasive cleaning device as claimed in claim 1 , wherein said housing includes a driver member and a retainer.
3. The abrasive cleaning device as claimed in claim 1 , wherein each slot within said housing includes a stop, the connection portion of the polymer strip engages said stop.
4. The abrasive cleaning device as claimed in claim 1 , wherein said housing includes a driver pad made of more than one section to form a circular shaped driver assembly.
5. The abrasive cleaning device as claimed in claim 1 , wherein the abrasive portion of said polymer strip is over molded to said connection portion.
6. The abrasive cleaning device as claimed in claim 1 , wherein said housing includes a hub, a spacer, a driver pad, and a retainer.
7. The abrasive cleaning device as claimed in claim 1 , wherein each slot within said housing includes a shape that matches an external profile of the connection portion of the polymer strip.
8. The abrasive cleaning device as claimed in claim 1 , wherein said polymer strip further includes a metal portion that is formed with the connection portion.
9. The abrasive cleaning device as claimed in claim 1 , wherein the abrasive portion of the polymer strip includes a metal strip that is coated and has diamond particles dispersed on an outside surface of the coating.
10. The abrasive cleaning device as claimed in claim 1 , wherein the abrasive portion includes diamond particles that wear off and new diamond particles are exposed to provide new cutting surfaces.
11. An abrasive cleaning device for modifying the surface of a floor comprising:
a rotatable housing that is operable to be connected to a cleaning machine, the housing having a plurality of slots; and
a polymer strip operable to be received within each of said slots, said strip having an abrasive portion and a connection portion, wherein the abrasive portion of said polymer strip includes a tube-shaped member that is operable to engage a work surface.
12. An abrasive cleaning device for use with a flooring machine, the cleaning device comprising:
a rotatable driver pad that is operable to be connected to a flooring machine, the driver pad having a plurality of radially extending slots located within a surface of said driver pad, said slot including a first region having a first width, a second region having a second width greater than the first width, and a length greater than the first width and the second width; and
a brush mountable to each slot, said brush having a mounting portion that slides within said slot, said brush further having an abrasive portion containing diamond particles that are dispersed on an exterior surface of said abrasive portion, said mounting portion including a first region having a first width, a second region having a second width greater than the first width, and a length greater than the first width and the second width, wherein the first region of the brush engages the first region of the slot, and the second region of the brush engages the second region of the slot.
13. The abrasive cleaning device as claimed in claim 12 , further comprising a retainer positioned adjacent said driver pad, said retainer holds said brush in place.
14. The abrasive cleaning device as claimed in claim 12 , further comprising a retainer, said retainer interlocks with said driver pad to secure said brush.
15. The abrasive cleaning device as claimed in claim 12 , wherein said brush further includes a metal strip that is disposed between said mounting portion and said abrasive portion.
16. The abrasive cleaning device as claimed in claim 12 , wherein said brush is made of more than one type of material.
17. An abrasive cleaning device for use with a flooring machine, the cleaning device comprising:
a rotatable driver pad that is operable to be connected to a flooring machine, the driver pad having a plurality of radially extending slots located within a surface of said driver pad; and
a brush mountable to each slot, said brush having a mounting portion that slides within said slot, said brush further having an abrasive portion containing diamond particles that are dispersed on an exterior surface of said abrasive portion, wherein said driver pad is made of four separate quarter sections that are arranged to form a circle.
