Machining Hard Materials
Whether turning, grooving or milling, we offer a wide range of cutting materials, inserts and toolholders for machining hard materials. For the machining of hard materials such as hardened steels, sintered steels, chilled cast iron or hardened cast iron, we have solid or corner-tipped CBN and ceramic in our product portfolio.
Solid or corner-tipped CBN inserts?
The real question is: For which application do I use solid CBN inserts and when do I use corner tipped inserts? Or, for which application and how do I combine the use of corner tipped and solid CBN inserts? In general, solid CBN inserts usually allow a better distribution of cutting passes, drawn cuts and preturning machining technique. If these advantages can be transferred to your machining operation, their use may be beneficial.
Our SPK engineering experts can help you determine whether solid CBN inserts are a viable option for your application. Likewise, whether mixed ceramics are a technical and economical alternative for your machining case.
Special Tools
One size does not fit all and some workpieces require a special tool for machining. Here you benefit from our comprehensive machining know-how.
Special tools start with us at the cutting edge with the chamfer geometry, continue with the insert geometry and end with the special tool holder, which can be designed with one or more cutting edges. Naturally, these are matched to the interface of the toolholder system you are using.
Hard Milling
Hard milling allows you to eliminate some or all of the grinding of the part. The reason for this is that excellent surface quality can also be reliably achieved with hard milling.
Our SPK engineering team will be happy to share their insider knowledge of hard milling. The benefits to you are the shorter production times and lower production costs that can be achieved with hard milling.
