The meaning of automation of treatment of lathe bed lamina and benefit are tremendous: ① raises utilization rate of equipment and installations. As a result of,this is handling time or result of auxiliary time reductive. Of the blade treatment machine tool that home becomes independent for the most part at present use efficiency to be in 30% ～ 40% between, a few abroad machine tools that introduce automation product line use efficiency to be able to achieve 70% above. ② reduces the cost of the product. As a result of,this is of product percent defective reduce and of equipment productivity rise, lay in among decrease, of landline simplify and of employee decrease, workshop area is reduced and production attempers simplify etc. ③ improves product quality. Because decrease to be affected with what excluded factitious factor,this is. ④ reduced many worker. Because use automatic device,this is, achieve much chance administration, do not have life to produce even. ⑤ from go up at all improve labor condition, reduce production to harm. ⑥ improves company image, enhance company competition ability.
