短納期のMNリーマ、特殊要件に対応する新しい切削材料

MAPALは2つの新しい切断材料であるHP016 と HP018 をご提供いたします。HP016とHP018は、高合金鋼、ステンレス鋼、鋳鋼、焼入れ鋼のリーマ加工に必要な条件に合わせて特別に設計されています。HP016は、断続切削を伴う全ての加工に適しており、HP018は連続切削に使用されます。どちらも、コバルト含有量の少ない2種類の炭化物にシリコンをドープしたPVDコーティングを施しているため、耐摩耗性に優れ、寸法精度に優れています。

The PVD coating has a fine crystalline microstructure, combining high levels of hardness and ductility. The cutting materials are thermally very stable and offer impressive high-temperature stability and coating adhesion. To create an optimum surface in through bores and blind bores, the PVD coating is deposited in the µm range. This ensures the cutting edges retain their sharpness.

The new cutting materials are used for market launch in the reamers in the MN series by MAPAL, among others. These tools represent the utmost accuracy and are now also ideally suitable for use in hard reaming applications as well as reaming stainless steel thanks to the new cutting materials. They operate according to the MAPAL principle – with one insert and a guide pad opposite. Depending on the application, the guide pads are made from carbide, cermet or PCD.

Thanks to optimisations in design, manufacturing and logistics, MAPAL supplies custom-made carbide and cermet reamers within ten working days. ©MAPAL

To reduce delivery times for single-bladed reamers significantly, MAPAL has streamlined the portfolio and is now focusing on eight series of MN reamers. Thanks to optimisations in design, manufacturing and logistics, the company is in a position to supply custom-made carbide and cermet reamers within ten working days. No one has achieved this in the sector until now. In addition to the two new cutting materials, many cutting materials and coatings for all common workpiece materials are available. The inserts can be delivered ex stock with all standard cutting leads, AS, DZ, EK and SZ.
