在线切割机床上,电极丝张力的大小,对电火花战切割加工的精度与效率有着直接的影响。张力越小.加工精度与效率越低;张力越大,加工精度与效率都高,但是,张力过大电极丝容易拉断.因此,必须将电极丝的张力控制在—个适当的范围内,而现有电火花线切割机床的张力不能测定,为此,日本 SHIMPO公司新近开发了一种张力仪,可以直接安装在现有的电火花线切割机床上,专门用来测量电火花线切割机.摩上电极丝的张力,以便于最大限度地发挥电火花线如割机床的性能,为模具加工的高效化和高精度化提供方便.
On-line cutting machine, the size of the wire tension, the EDM cutting precision and efficiency have a direct impact. The smaller the tension, the lower the machining accuracy and efficiency, the larger the tension, the higher the machining accuracy and efficiency, however, the tension is too large electrode wire easy to pull off.Therefore, the electrode wire tension must be controlled within an appropriate range, However, the tension of the existing WEDM can not be measured. To this end, SHIMPO Co., Ltd. of Japan has recently developed a tension meter that can be installed directly on the existing WEDM, specifically designed to measure the WEDM Friction wire tension, in order to maximize the performance of WEDM such as cutting machine, mold processing for the efficient and high precision to provide convenience.
