Abstract
A chip treatment device 100 includes a box-shaped housing 110, and an upper surface panel 112 of the housing is connected to a sloped portion 114. The interiors of the housing 110 is divided into upper and lower areas by a partition panel 130, and to the areas are provided a first cutting fluid bath 150 and a second cutting fluid bath 160. Chains 240 stretched between driving sprockets 210 and chain guide units 230 are equipped with scraper units 250 moving in the direction of the arrow. The chips coming in from an entrance opening 180 is separated from cutting fluid while being conveyed on the separation panel 130. First and second filter units 170, 300 filter said cutting fluid.
Claims10
A chip treatment device for treating chips discharged from a machine tool, comprising:
- a box-shaped housing;
- an entrance opening formed to one end of said housing for introducing said chips;
- a discharge opening formed to the other end of said housing for discharging said chips;
- driven chain guide units provided under said entrance opening;
- driving sprockets equipped above said discharge opening for driving chains;
- a pair of chains stretched between said driving sprockets and said driven chain guide units;
- one or more scraper units mounted to said chains;
- a partition panel extending between said driven chain guide units and said driving sprockets;
- said partition panel having a first downwardly sloped portion and a second upwardly sloped portion defining;
- a first cutting fluid bath formed above said partition panel;
- and
- a second cutting fluid bath formed under said partition panel;
- wherein said scraper units convey said chips along the upper surface of said partition panel.
