With the MP6 geometry, Walter states it is rounding off its range for the medium machining of steel – combining features such as a positive rake angle, with those of roughing inserts, for example a tough cutting edge.
Walter highlights that this makes the MP6 the perfect link between the existing MP4 geometry for medium machining, with excellent chip breaking on soft steels, and the RP4 for roughing operations, with tough cutting edge for high feeds. Walter offers the MP6 geometry in CCMT, DCMT, TCMT and VBMT basic shapes. The short primary chamfer, which is characteristic of roughing inserts, ensures a high degree of stability, even in challenging conditions, for example when machining forged parts or components with interrupted cuts. The 18 degree rake angle, tough cutting edge, and special chip breaking geometry also ensure excellent chip control during medium machining.
Walter AG specifies feeds from 0.1mm to 0.35mm and depths of cut from 0.4mm to 4mm as the range for the machining parameters. To prevent vibration, for example with thin walled components, Walter has given the MP6 geometry an open chip breaker groove. This reduces the cutting pressure even when cutting at a greater depth. This also makes the MP6 ideal for unstable components and components with long overhangs, for example during internal turning. Its straight cutting edge also makes it suitable for use as a chamfer insert for boring tools in steel, regardless of the application.
“The new Tiger·tec® Gold grades also have a positive impact on tool life. WPP10G, WPP20G and WPP30G are adapted to different operating conditions, thereby improving tool life and performance across a broad range,” comments the company.
