Abstract
Dust collection for an abrasive tool is disclosed. In one embodiment, a first dust extraction component extracts dust from an upper part of material that is machined, while a second dust extraction component extracts dust from a lower part of the material by the abrasive tool. The first dust extraction component and the second dust extraction component collect about 100% of dust generated from the material.
Claims20
A dust collector for an abrasive tool, comprising:
- a first dust extraction component that extracts dust from an upper part of material machined by the abrasive tool;
- a second dust extraction component that extracts dust from a lower part of the material machined by the abrasive tool;
- and
- wherein the first dust extraction component and the second dust extraction component collect about 100% of dust generated from the material during a machining operation by the abrasive tool.
A dust collector for a sawing machine that uses an abrasive blade to cut material located on a support table, the dust collector comprising:
- a pair of abrasive guards mounted about the abrasive blade, wherein each of the abrasive guards are located at opposing sides about the abrasive blade;
- a pair of self-adjustable side shields mounted about the abrasive guards, wherein each of the self-adjustable side shields is located about one of the abrasive guards to close off any side openings between the abrasive guards and the support table;
- an upper exhaust connection port located between the pair of self-adjustable side shields at one end thereof, wherein the upper exhaust connection port closes off any openings between a back end of the abrasive guards and self-adjustable side shields from the cutting area to the surrounding area;
- a dust duct located below the support table to collect dust generated from the material during the cutting operation with the sawing machine and guide the dust in a direction that is in back of the cutting area of the material;
- a lower exhaust connection port coupled to the dust duct;
- and
- a dust cover located at one end of the dust duct proximate the lower exhaust connection port.
A dust collector for a dry cutting sawing machine, comprising:
- a pair of abrasive guards mounted about an abrasive blade of the dry cutting machine, wherein each of the abrasive guards are located at opposing sides about the abrasive blade;
- a pair of self-adjustable side shields mounted about the abrasive guards, wherein each of the self-adjustable side shields is located about one of the abrasive guards to close off any side openings;
- an upper exhaust connection port located between the pair of self-adjustable side shields at one end thereof, wherein the upper exhaust connection port closes off any openings between a back end of the abrasive guards and self-adjustable side shields from the cutting area to the surrounding area;
- a dust duct located in a location that is below material that will be cut by the dry cutting machine, wherein the dust duct collects dust generated from the material during the cutting with the dry cutting machine and guides the dust in a direction that is in back of the cutting area of the material;
- a lower exhaust connection port coupled to the dust duct;
- and
- a dust cover located at one end of the dust duct proximate the lower exhaust connection port.
