NX technology: For surface qualities below Ra 0.1 μm
FRAISA’s NX face-finishing cutter is the latest innovation in finishing. The new milling cutter mills plane surfaces that are both visually and measurably of top quality. The secret lies in its axially and radially offset finish-cutting edge. Thanks to this offset, the finish-cutting edge cuts a precisely defined cross-section of chip measuring just a few hundredths of a millimeter. The finish-cutting edge is designed exactly for this chip cross-section and produces brilliant surface qualities.
The NX face-finishing cutter enables you to machine parts to surface roughness qualities of Ra < 0.1 μm. For many parts, this eliminates any need for a further process step as grinding is no longer necessary. The great advantage: The part can be finished in the same process on the same machine, saving considerable cost and time.
The NX face-finishing cutter has been designed so that even small, unavoidable radial deflections of the tool do not affect the machining result.
Since a perfect transition is often desired between the base and the wall, the NX face-finishing cutter also has short cutting edges at its circumference, so that step-free transitions can be created.
If you value outstanding surface roughness qualities or want to embellish visible components, you will be amazed by what FRAISA’s new NX technology has to offer.
- Top surface quality Visually and measurably much better surface roughness quality than with conventional tools
- Easy to use Tools can be used for normal 2D facing or for pocket milling
- Ideal life cycle with FRAISA ToolCare® tool management, FRAISA ReTool® tool reconditioning, and FRAISA ReToolBlue tool recycling
- Reduced process costs Times for finishing processes such as grinding or polishing are cut significantly
- FRAISA ToolExpert® 2.0 cutting data calculator for quick and easy provision of cutting data
The technologies of the NX face-finishing
New feature combines with tried and trusted: The new technology of cutters with a face-finishing cutting edge is characterized by the fact that an additional cutting edge is ground between the existing ones.
Thanks to the high-precision shank, the smooth transitions and fine balancing, the tool functions superbly.
NX face-finishing cutter for the very best surface quality – visually and measurably
Choosing the right strategy
If you want to obtain surface finishes of the highest quality, it is crucial you choose the right strategy. The following requirements should be taken into account:
Application tips for tools with a face-finishing cutting edge
The right workflow is important to minimize the amount of rest material in the corners of a pocket or step. Our product developers therefore recommend prefinishing after roughing and then finishing the base first before the wall.
The NX face-finishing cutter will mill the base and the wall together. Machining of the base is then complete. The wall still has a minimal allowance and is then finished with a finishing tool.
Measuring the tools
When measuring the tool on the machine using a laser, it is very important to specify the correct tool offset. To measure the diameter, a length offset Loff of at least h must be specified – FRAISA recommends an Loff of 1–2 mm.
Machining precision also requires taking a close look at the radius offset. Why? The lowest point of the tool is not at the cutting-edge corner, but a few tenths of a millimeter towards the center. A radial offset Roff of c must therefore be specified in the tool table.
FRAISA ReTool® – Industrial tool reconditioning with performance guarantee
FRAISA ReTool® offers an all-round service that restores your used tools to their original performance level and optimizes your processes. FRAISA and third-party tools are reconditioned using the very latest technology – and in a resource-friendly way. The outcome: mint-condition tools as productive as they were the first day they were used. And to make things even better, your level of investment is lower than if you were to buy new tools, you increase your productivity and you save costs.
FRAISA ReTool® – a performance guarantee founded on integrated development of the tools and the reconditioning process
We guarantee that following their reconditioning with FRAISA ReTool®, your used tools will be restored to the original performance level they had when new. Our ability to provide this performance guarantee is a priority of our team of experts right from very early on in product development.
That’s why the development of the reconditioning process is an integral part of the development phase, alongside the actual product tests and calculating the cutting data. Strict rules apply: the FRAISA ReTool® process is approved only if we are able to fulfil our performance guarantee 100%.
