Patent ID: 6960124

Claim:
A cutting machine, comprising: a cutting support frame comprising a bottom collecting tray and a cutting table mounted thereon for supporting a work piece; a motor assembly, which is supported on said bottom collecting tray, comprising a driving motor and a driving shaft which is driven to be rotated by said driving motor; a cutting head arrangement comprising a cutting blade coaxially mounted to said driving shaft at a position overhanging said cutting table, wherein said cutting blade has a cutting area defined at an outer circumferential portion thereof when said cutting blade cuts said work piece; and an environment control arrangement, comprising: an end collecting tray, which is upwardly extended from said bottom collecting tray, 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 is upwardly extended to a position above said cutting area of said cutting blade, wherein said end collecting tray has a concave reflecting surface to form said collecting chamber for collectively reflecting said residual particles when said residual particles spread towards said concave reflecting surface of said end collecting tray; a suction source having a sucking inlet provided at a lower portion of said end collecting tray for collecting said residual particles within said collecting chamber by means of sucking effect; and a detouring guide for detouring said residual particles towards said sucking inlet of said suction source, wherein the detouring guide comprises a guider wall, having a plurality of guiding through grooves provided thereon, detachably mounted at an opening of said collecting chamber of said end collecting tray and a plurality of guiding fins rearwardly and inclinedly extended from said guider wall, wherein said guiding fins are capable of detouring said residual particles towards said sucking inlet when said residual particles spread towards said collecting chamber through said guiding through grooves.
