Negative insert takes heavy cuts on
automatics
A D-style negative insert allows users of sliding head automatic lathes to take deep cuts at high speed without overloading the insert's cutting edge or the machine tool.
WNT (UK) said that its recently introduced F32 geometry D-style insert is giving more machining power to sliding head automatic lathes WNT (UK) told Manufacturingtalk that while not normally an option on sliding head lathes, the DNGU style insert features a negative insert style that allows operators to take deeper cuts at high speeds

Precision modular boring tools provide users with roughing and finish boring capability through an extensive range of modular couplings and extensions.
Cutters make light work of hard materials
Tool life when cutting hard materials up to 70 HRc is greatly improved, thanks to the development of a PVD-multilayer coating used on solid carbide milling cutters.
The reason for this is the insert's ground edge and geometry, so users can still take large cuts at high speed without putting too much pressure on the the cutting edge, or the machine tool and work piece.
The inserts have small corner radii of 0.08mm and 0.15mm, which is of tremendous help in reducing pressure on the insert and workpiece when compared to those encountered when using pressed inserts.
In addition, the smaller radii also ensure that the cutting forces are axial rather than radial.
This, combined with the geometry, grade and tool coatings, ensures increased tool life, said WNT (UK).
The inserts are available with a choice of TiN or TiAlN coatings, making them suitable for a wide range of applications including cutting steel, stainless and super alloys.
By switching to a negative insert style users are able to reduce tooling costs, because each insert has four cutting edges as opposed to the two found on positive inserts of this style.
A further advantage is the chipbreaker profile, which provides an extremely sharp cutting edge - made possible in part by the K30-grade substrate.
Because of the negative design and the small corner radii these inserts are only suitable for use in the correct holders supplied by WNT (UK).
These toolholders are also manufactured with greater clearance and to tighter tolerances. Request a free brochure from WNT (UK) ...
