Abstract
A horizontal machining center 1 has a table 20 on a bed 10. An X-axis slidable surface is provided on the bed 10, and a column 30 is driven by a servo motor 32. A spindle stock 40 is supported on the column 30 and is driven along a Y axis extending in a vertical direction. An automatic tool change unit 100 replaces a tool on a spindle 44 on the spindle stock 40 with a tool in a tool magazine. An X-axis cover 200 provided between the table 20 and the column 30 has a plate-like fixed cover 205 and a pair of slidable covers 210. The fixed cover 205 is disposed with one edge thereof passing through an opening 150 formed in the middle of the tool magazine 110. Structured in this way, the horizontal machining center can have a reduced size.
