中走丝线切割工件装夹的注意事项 1、 工件装夹前必须先清理干净锈渣、杂质。 2、 模板、型板等切割工件的安装表面在装夹前要用油石打磨修整,防止表面凹凸不平,影响装夹精度或与下喷嘴干涉。 3、 工件的装夹方法必须正确,确保工件平直紧固。 4、 严禁使用滑牙螺钉。螺丝钉锁入深度要在8mm以上,锁紧力要适中,不能过紧或过松。 5、 压块要持平装夹,保证装夹件受力均匀平衡。 6、 装夹过程要小心谨慎,防止工件(板材)失稳掉落。 7、 工件装夹的位置应有利于工件找正,并与机床行程相适应,利于编程切割。 8、 工件(板材)装夹好后,必须再次检查确认与机头,极间线等是否干涉现象。 The matters needing attention in WEDM workpiece clamping. 1, workpiece must first clean the rust slag, impurity clip before. The mounting surface cutting the workpiece 2, template, template to use oilstonegrinding the dressing in clamping the front, to prevent uneven surface and theinfluence of clamping precision or interfere with the nozzle. 3, workpiece clamping method must be correct, ensure the workpiece straightnessfastening. 4, prohibited the use of sliding screw. Screw locking depth in 8mm above, clamping force should be moderate, not too tight or too loose. 5, a pressing block to ensure the paperback clamp, clamping pieces of uniform stressbalance. 6, the clamping process should be careful to prevent the workpiece (sheet) instabilityfall. 7, a workpiece clamping position should be conducive to the workpiece is looking to adapt and stroke of machine tool, cutting to programming. 8, the workpiece clamping (plate) good, should be examined and the head again, pole to pole line and whether the interference phenomenon. |
