Horizontal machining center

摘要

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.
