Easy-cut and dynamic up to 5.2xd deep

The multi-functional MB-NVDS (MFC) tools launched last year are extremely popular. Each MFC tool enables up to 96 different applications to be handled, allowing users to achieve significant reductions in inventory and machine setup costs as well as tool change times – and reduce their production costs long-term.

Thanks to the high degree of market acceptance of MB-NVDS (MFC) tools, the MB-NVDS tool family has been expanded. While the MB-NVDS tools already available on the market are exhibiting excellent performance in finishing and conventional HPC roughing operations, the new family members are focused on HDC (High Dynamic Cutting).

That is, these tools, with their very robust cutting edge geometry, are ideally suited to penetrating and milling out the component using the entire length of the cutting edge.

The cutting profile of the new MB-NVDS tools has been designed with a more positive edge. A cutting angle of 10° and a treated cutting edge result in a soft and low-vibration cut that in turn reduces machining forces, power consumption and torque input. With the aid of the redesigned double groove and continuous polished teeth, it is now possible to absorb greater thermal and mechanical loads during HDC trochoidal machining.

The new MB-NVDS 5.2xd version can be used to make deep holes and to achieve extremely high material removal rates when HDC-S milling.

The ToolExpert MFC software developed specifically for the MFC family has been updated with the many new applications possible and now provides an outstanding overview of the broad range of uses of this truly unique MB-NVDS (MFC) tool family.

MFC solution for successful production

This is where Multi-functional Cutting (MFC) comes into its own. The goal of MFC product development is to reduce these complexities without compromising on performance.

Thanks to MFC, the customer is able to focus fully on their competency in CAM programming and enhance their competitiveness even more in the process!


The technologies behind the new MB-NVDS (MFC) tools

New technologies have a clear goal: They have to offer the user a number of definite benefits. To achieve this, only as many technologies as necessary are built into the tools, in order to obtain the best price-performance ratio. This also includes the application recommendations and cutting data that FRAISA develops at the same time as the tool technology.

ToolExpert MFC and application technology
Knowledge of the application

In addition to developing the new MB-NVDS-MFC mills with 10° cutting angle, we have also compiled comprehensive cutting data that we have incorporated into the new version of ToolExpert MFC. With just a few clicks, you select the material, application and tool and obtain the parameters that need to be programmed for your machine control or CAM system.

When selecting the tool you require, ToolExpert MFC provides you with information on the performance index and areas. The new MB-NVDS mills with 10° cutting angle and treated cutting edge are ideally suited to HDC milling. The existing MB-NVDS mills (8102/8202 and 8105/8205) are ideally suited to HPC milling. This allows you to match the MFC tools perfectly to your machine environment and application.

Central air and cooling channel

All MFC tools have a central air and cooling channel. In combination with the penetration edge, this channel ensures maximum process reliability and performance, because the chips are immediately removed upwards and away from the area of the penetration edge. Nevertheless, FRAISA recommends that coolant is delivered internally when making penetration depths greater than 1.5xd.

HDC (High Dynamic Cutting) milling

HDC milling offers greater productivity, process reliability and lower loads than HPC milling. However, the faster cutting speeds mean that the processing temperatures are considerably higher. Depending on the component being milled, the working length is longer or shorter and this has a direct impact on the temperature. Reduce or increase the cutting speed in order to regulate the processing temperature; this also enables you to control the amount of tool wear.


Using state-of-the-art CAD-CAM systems to gain a competitive edge

The CAD-CAM system assigns the type of application and the milling strategy to the component to be machined. State-ofthe- art CAD-CAM systems enable a multitude of different machining strategies. High Dynamic Cutting (HDC, aka trochoidal milling) has been implemented in many CAD-CAM systems recently. This process offers significant economic advantages and is a real alternative to High Performance Cutting (HPC) and High Feed Cutting (HFC).

The competitive advantage is to be found in the knowledge of which machining strategy is ideal in respect of productivity, safety, quality and the machine environment. The programmer’s own knowledge of the possibilities offered by their infrastructure also plays a crucial role.

In order to further improve coordination between the infrastructure and use of the CAD-CAM system, FRAISA includes this key element in its regular cutting seminars. Conversations with participants at these seminars reveal that there is a great deal of performance potential still to be teased out.
