Patent ID: 7451758

Claim:
A cutting machine, comprising: a cutting support frame having a bottom side and comprising a cutting table supporting above said bottom side for supporting a work piece on said cutting table; a motor assembly, which is supported above said cutting table, comprising a driving motor, a cutting head arrangement comprising a cutting blade which is overhanging said cutting table and powered by said driving motor, wherein said cutting blade has a cutting area defined at an outer circumferential portion thereof for contacting with said work piece; and an environment control arrangement, comprising: an end collecting tray, which is upwardly extended from a rear portion of said bottom side of said cutting support frame, having a collecting chamber for collecting residual particles of said work piece while said cutting blade cuts said work piece, wherein said end collecting tray has a predetermined height that said end collecting tray is upwardly extended above said cutting area of said cutting for collecting said residual particles of said work piece to said bottom side of said cutting support frame; and a detouring guide, which is mounted on said cutting support frame, comprising: a guider wall, having a plurality of guiding through grooves spacedly provided thereon, mounted in front of said end collecting tray; and a plurality of guiding fins rearwardly extended from said guider wall along edges of said guiding through grooves respectively, wherein said detouring guide is adapted for guiding said residual particles towards said collecting chamber through said guiding through grooves and for detouring said residual particles towards said bottom side of said cutting support frame via said guiding fins; wherein said detouring guide further comprises a mounting arrangement for detachably mounting said guider wall in front of said end collecting tray, wherein said mounting arrangement comprises a longitudinal arm longitudinally supported at an upper portion of said end collecting tray and at least a detachable coupler which is upwardly extended from a top edge of said guider wall and is detachably mounted to said longitudinal arm in such a manner that when said detachable coupler is mounted at said longitudinal arm, said guider wall not only suspendedly supports in front of said end collecting tray but also pivotally moves at an inclined position to align said guiding through grooves to face towards said cutting blade.
