用极不均匀分布的锥形锪钻锪孔

在每个加工流程中都存在着提高产能的潜力。即使在可避免的二级加工中，也存在着明显的改进潜力。这在新的锥形锪钻中得到了证实。
MAPAL 的 90° 沉孔。
新开发的锥形锪钻以明显减少的轴向力进行加工。锥形锪钻的切削刃采用非均匀分布。与常规的锥形锪钻相比，轴向力减少了 50 % 以上，径向力减少了 25 %。这种类型的最佳应用条件在刀具上形成的微振动极小，由此而能够获得极高的精度和极好的表面质量。沉孔的高精确度保证了螺栓和铆钉的稳固连接，从而防止了在安装的情况下，在载荷的作用下，发生孔底下沉的现象。机器负载的降低延长了刀具的使用寿命。刀具也由于其平稳、稳定的运行而能够采用高切削数据进行加工。由此而明显节约了时间。

  • HSS design, coated

    The three cutting edges on the countersinks from MAPAL made of HSS with highperformance coating have extremely unequal spacing. As a consequence the axial forces are reduced and significantly less vibration is generated on the tool. In this way higher accuracies and better surface finishes are achieved. The precision of the countersink leads to the directly improved contact of bolted and riveted joints.

    Solid carbide design, coated

    In addition to the high-performance coated HSS designs of countersinks, MAPAL also offers selected diameters as a coated solid carbide version. Along with the advantages of the unequal spacing, the solid carbide design offers additional advantages during the machining of demanding workpiece materials such as titanium, high-alloy cast iron, Inconel or CFRP. Longer tool lives and higher cutting speeds are reliably achieved compared with the coated HSS design

  • Two custom drills with countersinking step from MAPAL

    Special drill designs with countersink step

    MAPAL offers the possibility of manufacturing a countersink step for almost all solid carbide drills as a special solution. In this way two machining operations, drilling and countersinking, can be realised using one tool and non-productive times reduced. The latest production technologies as well as flexible manufacturing at MAPAL make possible short delivery times for custom solutions worldwide.
