Abstract
A cutting machine of a type having bellows means disposed at least on one side of a chuck table to be reciprocated. A protective sheet covering the upper surface of the bellows means is disposed. One end of the protective sheet is reciprocated in accordance with the reciprocation of the chuck table, while the other end of the protective sheet is connected to winding means. When the chuck table is moved forward or backward, the protective sheet is gradually wound up by the winding means. When the chuck table is moved backward or forward, the protective sheet is gradually wound off from the winding means.
Claims10
A cutting machine including:
- a chuck table to be reciprocated between one end position and another end position;
- bellows means disposed at least on one side of said chuck table as viewed in a reciprocating direction of said chuck table, fixed at one end to said chuck table, and fixed at another end to a stationary member;
- and
- cutting means for cutting a workpiece held on said chuck table, and configured such that
- when said chuck table is moved forward and/or backward, said cutting means acts on the workpiece held on said chuck table to cut the workpiece, whereupon swarf scatters at least on the one side as viewed in the reciprocating direction of said chuck table, and
- when said chuck table is moved forward or backward, said bellows means is expanded or contracted;
- and wherein
- a protective sheet for covering an upper surface of said bellows means is disposed,
- one end of said protective sheet is reciprocated in accordance with reciprocation of said chuck table, and another end of said protective sheet is connected to winding means, so that when said chuck table is moved forward or backward, said protective sheet is gradually wound off or wound up by said winding means in accordance with forward movement or backward movement of said chuck table.

A cutting machine comprising:
- a chuck table to be reciprocated between one end position and other end position;
- a first bellows means disposed at a side of said chuck table as viewed in a reciprocating direction of said chuck table, fixed at one end to said side of said chuck table, and fixed at other end to a first stationary member;
- a second bellows means disposed at an opposite side of said chuck table as viewed in a reciprocating direction of said chuck table, fixed at one end to said opposite side of said chuck table, and fixed at other end to a second stationary member;
- and cutting means for cutting a workpiece held on said chuck table, and configured such that when said chuck table is moved forward and/or backward, said cutting means acts on the workpiece held on said chuck table to cut the workpiece, whereupon swarf scatters at least on the one side as viewed in the reciprocating direction of said chuck table, and when said chuck table is moved forward, said first bellows means is contracted, and said second bellows means is expanded, and when said chuck table is moved backward, said first bellows means is expanded, and said second bellows means is contracted;
- and
- wherein a first protective sheet for covering an upper surface of said first bellows means is disposed, one end of said first protective sheet is reciprocated in accordance with reciprocation of said chuck table, and other end of said first protective sheet is connected to a first winding means, and a second protective sheet for covering an upper surface of said second bellows means is disposed, one end of said second protective sheet is reciprocated in accordance with reciprocation of said chuck table, and other end of said second protective sheet is connected to a second winding means, so that when said chuck table is moved forward or backward, said first and second protective sheets are gradually wound up or wound off by said winding means in accordance with forward movement or backward movement of said chuck table.
