打导向孔

用于冷却系统的深孔非常普遍，尤其是在注塑方面。为了实现对超长钻具的良好导向，建议使用较短的刀具来打导向孔。MAPAL公司在此不仅提供正确的产品，而且还提供相应的专业支持，以确保在圆度和精度方面的目标。
由于钻孔过程通常在倾斜表面上进行，因此用户可以通过打导向孔来避免弯曲和断裂刀具。

Deep hole drilling

Deep drilling up to 40 and 50xD is very common in the die & mould sector. This type of drilling requires specialised tools. The most common are single-lip drills, with these tools being used on special drilling machines. Solid carbide drills are a real alternative for small and medium-sized components with bore diameters of up to 12 mm. The deep hole drills are equipped with two guiding chamfers and thus ensure good guidance in the bore.

  • MEGA-Deep-Drill

    Solid carbide deep drill
    • Process-reliable and efficient production of deep bores up to 40xD
    • Up to 80 percent shorter machining times compared to single-lip drills
    • Self-centring chisel edge
    • Four guiding chamfers for high bore quality

Reaming

The bores for certain pins and positions require a high degree of accuracy in terms of roundness and diameter. A final reaming process is therefore mandatory. The pre-machining of these bores must also meet the requirements of the reaming tools in order to achieve the desired results.

Decades of expertise at MAPAL means a wide range of available products that are individually selected for specific requirements.

  • MEGA-Drill-Reamer

Countersinking

Each bore is usually pre-machined on the edge with a countersink. Countersinking is a simple application, but some bores have special surface quality requirements. The usual tools are made from solid carbide but also HSS. The innovative countersinks from MAPAL also offer advantages for countersinking operations through better performance and higher surface quality.
