Mapal's EasyAdjust System Simplifies External Reaming Setup
Mapal’s EasyAdjust (EA) tool system is designed for external reaming for machining of small outer diameters.
Mapal’s EasyAdjust (EA) tool system is designed for external reaming for machining of small outer diameters. The back taper of the insert is already integrated in the cassette that serves as insert holder, meaning there is no need to set the back taper of the minor cutting edge. All that needs to be set is the overhang of the insert with regard to the guide pads.
In the case of external reamers with small machining diameters, setting can still be quite a challenge. A measuring sensor has to be inserted into the external reamer, zeroed to the guide pads and located at the cutting edge to set the corresponding overhang. This procedure is aggravated by a very limited view of the inside of the tool. To simplify this process, the cassette of the EA System is integrated in an additional cassette. This cassette can be removed, and the insert can be set quickly and easily using a micrometer or a surface plate, the company says. The appropriate setting dimension for the insert is engraved on the reverse of the tool. This dimension corresponds to the midpoint of the tolerance for the fit to be created.
Once setting is complete, the cassette is mounted again. The changeover accuracy is 2 to 3 microns. Thanks to this accuracy and the simplicity of setting the insert, the new system makes it easier to comply reliably with the required tolerances and extremely precise fits, even in the case of small diameters, Mapal says.
Economic efficiency is an important consideration when choosing tools for challenging metals.
Liquid coolant offers advantages unrelated to temperature. Forced air is the fluid of choice in this shop...but even so, conventional coolant can't be eliminated entirely.
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
