Machine Tool
First Claim
1. A machine tool for processing a workpiece through relative movements between the workpiece and a tool in three directions of X-, Y- and Z-axes, comprising:
- a bed providing the base of the machine, a column movable along a guide extending in the left-and-right direction on a rear part of the bed;
a spindle head movable along a guide extending in the up-and-down direction on the front face of the column and having a spindle receiving a tool at the end thereof;
a trough disposed within a recess extending in the back-and-forth direction in the center of the bed;
a table, disposed over the trough for the back-and-forth liner motion along a pair of guides extending in the back-and-forth direction and disposed on the bed at the either side of the trough, for mounting the workpiece;
a feed screw, disposed outside of the trough, and inside, adjacent and parallel to either one of the pair of guides, for feeding the table in the back-and-forth direction;
a splashguard, enclosing a machining zone, for preventing the chips and the machining fluid from spreading out;
a cover for covering the guides for the table and the feed screw over the full stroke of the back-and-forth motion of the table and for introducing the chips and the machining fluid into the trough;
a process nozzle, disposed around the spindle, for directing the machining fluid to the machining zone; and
a chip conveyer nozzle, disposed in the trough, for directing the machining fluid to transfer the chips within the trough out of the machine.

Abstract
The invention relates to a machine tool which processes a workpiece through the relative motions between a tool and the workpiece in X-, Y- and Z-axes three directions. The object of the invention is to ensure the collection and ejection of the chips with a simple configuration. The invention comprises a trough 27 provided in the central part of a bed 1 to extend in back-and-forth direction, a pair of guides 9 disposed at left-and-right sides of the trough 27, a Z-axis feed screw 31 disposed adjacent one of the guides 9, and slant covers 37 and Z-axis telescopic covers 39 for covering the pair of guides 9 and the Z-axis feed screw 31. Chip conveyer nozzles 47 and 49 are provided within the trough 27 for directing the machining fluid to eject the chips from the machine.
