Abstract

PURPOSE:To start a chip conveyer only when chips are accumulated, by constituting a device such that the device, counting the time, taken for a load, or an integrated value of the time of the load by a load counting device for the load selected by a load selector, compares this counted value with the preset start and stop time of the conveyer. CONSTITUTION:The time, taken for a load, or an integrated value of the time of the load is counted for the load, applied to a main spindle motor 14 and a feed motor 15 of a tool 12, detected by a main spindle load detector 16 and a feed motor load detector 17, and the counted value is compared with the preset start and stop time condition of a chip conveyer 22. On the basis of this compared result, an automatic start stop device 24 outputs a start stop instruction to a starting motor 25, automatically starting or stopping the chip conveyer 22. That is, the chip conveyer 22, which is started only when chips are accumulated in the chip conveyer 22, enables energy saving and operatorlessness to be promoted.
