2、work报废和重工,The Six Big Equipment Losses设备的六大损失,Breakdowns故障停工The time that is lost for production due to equipment failures.由于机器故障而损失了生产时间How many hours a month is lost due to breakdowns?每个月因机器故障而损失了多少小时?Is it normal to fight the breakdown fires?紧急处理机器故障是属于正常的情况吗?How often do we have breakdowns due t
3、o incorrect care?因为不正确的照顾而产生的故障频率有多高?,Types of Breakdowns故障的型式,Function Loss(sporadic)Function Reduction(chronic)丧失功能(偶发性)功能降低(习惯性)Sudden Failures突然失效 Hidden隐藏的Random无规则的 Expected/ignored预料中的/被忽视Visible看得见 Minor impact影响较小,The Six Big Equipment Losses设备的六大损失,Set-up and adjustments架模和调整Set-up losses
4、are the losses of time due to the physical changing of tooling,fixtures or dies.架模损失是因为实际更换刀具、型规或模子而产生的时间损失Adjustment losses are the additional time it takes,usually after a set-up,to“adjust”the equipment to ensure that we have an acceptable part.调整损失通常是在架模之后,为了确保产出良品而额外耗用的调整设备时间,The Six Big Equipme
5、nt Losses设备的六大损失,Idling and minor stoppages空转和不严重的中断Are the losses when we have small problems e.g.a part gets stuck in the machine,or other minor problems that dont require a mechanic.这类损失是起因于小问题,如:零件卡在机器上或是其它不需要修理人员的次要问题,The Six Big Equipment Losses设备的六大损失,Speed losses无法全速运转Are the result of not b
6、eing able to run at design or application speed.因下列问题造成无法依照设计或规定的速度运转:Old worn machine老旧损耗的机器Loose drive belts皮带松动What is the design/application speed?设计/规定的速度是多少?Never tested at the design/application speed从未测试能否以设计/规定运转,Start-up/yield losses(reduced yield between machine start-up and stable produc
7、tion)起动/生产损失(机器起动到稳定生产之间的产量缩减)These types of losses can result for the same reason as adjustment and set-up losses.这一类的损失可能与调整和架模损失具有相同的起因The time it takes to correct defects caused by tooling,warm-up,or other start-up issues.为了改正由于加工、暖机或其它启动原因造成的不良品所耗用的时间,The Six Big Equipment Losses设备的六大损失,Quality
