FAQ
パンチ、ダイ、ストリッパーに推奨する材種は何ですか？
条件によって違いますので、一概には言えません。ユーザーによって色々です。
パンチ EF10、ダイ KD20などが比較的多く使用されています。
ダイの切刃及びストリッパーなどワイヤー加工の場合は、超微粒子合金は不向き（電解腐食など）なケースもありますので、まずはご相談ください。

高速プレスで寿命を延ばしたい
切り刃のラッピングをお薦めします。
面粗度を上げる事により滑りを良くし摩耗を緩和します。
弊社では異形状も砥石ラップを行う事で精度を保持したまま0.3S以下の面粗度を約束します。 -
We are using fine grain and ultra fine grain carbide parts with wire cutting and EDM machines, but chipping occurs often during use.
Try our A10W.
This material maintains the transverse rupture strength of KD20, while having resistance to thermal cracking during EDM/WEDM improved. -
Can A10W be considered for use in electrical machining?
We believe A10W can be used safely even in electrical machining.
Fine particle grain cemented carbide inhibit crack propagation through mixing coarse-sized grain, and the heat affected layer's thickness is reduced through lowering the amount of Co. This is why we recommend A10W for wire EDM.
