鋳鉄や鋼鉄加工の新たな工具の開発
鋳鉄や鋳鉄材料は、機械加工で最も頻繁に使用される材料です。例えばポンプハウジング、コンプレッサー、ステアリングなどがあります。2つの成功例が示すように、マパールの開発者は常にこれらの大規模な材料グループの経済的な加工に焦点を当てています。
製粉用の新しい切削材料シリーズ
マパールは、鋳物や鋼鉄部品のミーリング加工に最適なCVDコーティングを施したインサートシリーズを開発しました。新しいコーティングインサートシリーズは、特に高い切削速度あるいはドライ状態でのミーリング加工時にその強さを発揮します。
新しいインサートシリーズのH C 7 6 0、HC770およびHC775は、非常に耐熱性の高いα酸化アルミニウムコーティングにより、コーティングの密着性が非常に高く、工具寿命が非常に長いことが特長となっています。ユーザーは、PVDコーティングを施したものよりもはるかに広い範囲で、非常に高い切削速度で使用することができます。
さらに新しい工具材種は、ドライ加工にも最適です。使用の前提条件となるのは機械条件が安定していることです。
Fine boring of interrupted bores with multiple cutting edges with EA system and CVD coating
For example machinists are faced with open or extremely interrupted bores in the case of gear pump cast housings. MAPAL has developed a multi-cutter fine boring tool with guide pads in order to machine such bores faster, reliably and more cost-effectively. MAPAL's own CVD coating, which ensures a long tool life, is used for cutters. It is ideally suited to difficult machining conditions during reaming and fine boring.
Multiple cutting edges on the tool significantly reduce the machining time compared with spindle tools or single-insert fine boring tools. At the same time, the guide pads arranged opposite the cutting edges ensure maximum accuracy. The tool can be adjusted with high precision. Appropriate distribution of material removal on the cutting edges ensures long tool lives and very good surface quality.
The EasyAdjust system (EA system) is used to clamp the indexable inserts. Its cassette holds the indexable insert stably and without any play. The back taper of the minor cutting edge is already integrated in the cassette, thus eliminating the need for back taper adjustment. Precise guiding of the cassette along a precision guide pin ensures that the back taper remains unchanged even during diameter setting.
