Workpiece separation apparatus

A workpiece separation apparatus, comprising:

• a separating container in which fluid is stored;
• an input cylinder configured to input a mixture of workpieces and chips;
• and
• a fluid supplying means configured to supply the fluid to the separating container;
• characterized in that
• the input cylinder is disposed such that a lower end thereof is inserted and is located within the separating container;
• the fluid supplying means supplies the fluid to the separating container from a part lower than a lower end of the input cylinder;
• an upper end of the input cylinder projects above an upper end of the separating container;
• and
• the separating container and the input cylinder are arranged such that the fluid overflows and flows out of the upper end of the separating container by a flow current generated within the separating container from a lower part to an upper part thereof and such that the fluid within the input cylinder does not flow out of the upper end thereof.
