Abstract

A cutting machine includes a bottom collecting tray, a cutting blade overhanging on a cutting table and having a cutting area defined at an outer circumferential portion thereof when the cutting blade cuts the work piece, and an environment control arrangement. The environment control arrangement includes an end collecting tray, which is upwardly extended from the bottom collecting tray, having a collecting chamber for collecting residual particles of the work piece while the cutting blade cuts the work piece, wherein the end collecting tray must be upwardly extended to a position above the cutting area of the cutting blade, and a suction source having a sucking inlet provided at a lower portion of the end collecting tray for collecting the residual particles within the collecting chamber by means of sucking effect.
