Abstract
A machine tool with an improved capability of discharging and collecting the cutting chips is disclosed. A bed (13) is provided with troughs (39) extending through the bed (13) in a direction substantially perpendicular to a direction of the movement of a table (15). The cutting chips are collected in the troughs (39) through a plurality of chutes (47) which have openings inclined downward towards the troughs (39) and which are provided below the upper surface of the table 15, to be discharged to the outside through chip discharge means (41) disposed in the troughs (39).
Claims12
A machine tool for machining a workpiece by moving the workpiece and a tool relative to each other, the machine tool comprising:
- a bed serving as a base;
- a spindle head for rotatably supporting a spindle having said tools mounted thereon;
- a table for said workpiece to be mounted thereon, said table moving along guide means disposed on the upper surface of said bed;
- table feed means for moving said table along said guide means;
- an inclined cover for covering said guide means and said table feed means of said table and causing cutting chips generated by machining said workpiece to fall downwards;
- a plurality of funnel-like chutes having openings for collecting the cutting chips below the upper surface of said table;
- a trough for receiving the collected cutting chips from said chutes through said opening thereof,
- chip discharge means for discharging the cutting chips received by said trough to the outside, said chip discharge means disposed in said trough.
A machine tool for machining a workpiece by moving the workpiece, said machine tool being adapted to collect cutting waste, comprising:
- a bed serving as a base;
- a table for said workpiece to be mounted thereon, said table being mounted for movement back and forward along the upper surface of said bed;
- table feed means for moving said table;
- an inclined extensible cover adjacent said table for causing cutting waste to fall downwards there along and away from said table;
- at least one chute for collecting said cutting waste falling from said inclined cover;
- at least one trough extending transversely through said bed tar receiving said chute collected cutting waste;
- and
- discharge means positioned one each within each said trough for discharging said cutting waste outwardly;
- also including a recover tank positioned to receive said cutting waste discharged outwardly by said discharge means;
- wherein the floor of each said through is sloped thereby aiding said discharge from each said trough;
- and
- wherein each said chute includes a splash guard.
