To provide a machining table for a workpiece of easily grinding property, which facilitating machining of end faces thereof and reducing facility cost.

A machining table 1 on which a workpiece 29 of easily grinding property is mounted and fixed includes: a negative pressure generating base 5 where a negative pressure space 4 applied with a negative pressure by a blower 21 is formed to be open to the upper surface; and an attachment plate 6 which is mounted over the negative pressure generating base 5 to cover the negative pressure space 4, where a plurality of sucking recesses 18 including a connecting passage 19 connected to the negative pressure space 4 are formed thereon. The machining table 1 includes a mount member 20 and porous suction plate 30 which are switchable with respect to the attachment member 6, thus changing a suction fixing method of the workpiece 29.
