Machining system

A machining system comprising:

• a single base unit;
• and
• multiple working machine modules which are mounted on the single base unit and are arranged in an arrangement direction,
• wherein each of the multiple working machine modules includes a machine tool module, the machine tool module including a modularized machine tool, and each of the multiple working machine modules is capable of being drawn out from the single base unit along a track extending in an intersecting direction that intersects with the arrangement direction,
• wherein arrangement regions, each of which being a virtual space demarcated on the single base unit, are arranged in parallel in the arrangement direction without a space therebetween such that the arrangement regions are adjoining each other, widths of the arrangement regions in the arrangement direction being equal to each other, and only one working machine module exists in each arrangement region,
• wherein a length of an interval in the arrangement direction between centers of two adjacent working machine modules each occupying a single arrangement region is equal to the width of the single arrangement region in the arrangement direction,
• wherein in the arrangement direction, a location of an end of an endmost arrangement region and a location of an end of the single base unit are the same,
• wherein the tracks of the single base unit include rail pairs provided parallel to the arrangement direction and extending in the intersecting direction, and a number of rail pairs provided on the single base unit corresponding to a number of the working machine modules mounted on the single base unit, and
• wherein at least one of the machine tool modules includes a horizontal spindle type module that performs a process on a work using a tool, and the horizontal spindle type module includes:
• a spindle, which is arranged such that a longitudinal axis thereof extends in the intersecting direction, and
• a chuck, said chuck being attached to the spindle and being configured to grip the work such that said work is able to be set in rotation by the spindle.
