Sanstone stružne ploščice CNMG 120412 QP1025

CNMG is a usable carbide turning indexable insert with its geometry and rigid mounting in the turning holder allows the possibility of turning different shapes and surfaces.

With its design and shape, this insert is indispensable in many lathe workshops.

Due to the strength and durability of the carbide, various steel alloys can be rough machined with this CNMG 120412 indaxeble insert.

You will be satisfied to use this carbide tool, as it has proven to be a grateful helper in many turning processes.

The tungsten carbide on this CNMG 120412 provides high temperature resistance, and at the same time the surface coating allows the material to be drained from the work process.

The geometry of this insert is made in such a way that it causes rigid turning during the rough turning process and well separates the chips from the mechanical process.

Zero free angle under the main cutting edge, provides excellent support to the cutting edge and thus prolongs the resistance of the tool to various influences. Radius 1.2 is specialy good for roughing.

Behind this product are many successes that guarantee the above-highstandard quality of these cnmg 120412.

You are welcome to buy with a guarantee of satisfaction.

QP1025 - ISO Grade P20 - The type of carbide grade and the coating on inserts is originally intended for turning steel , steel alloys but it also performs when turning other alloys.

• Material: ISO grade carbide (tungsten):
  • For steel P10-30 (between wear resistance and shock resistance)(See ISO grade tables.)
  • CVD coating - thicker rough layer coating
• Feed speed in mm/rev - 0.1-0.3
• Cut depth - 1.0mm - 5.0mm
• Cuting speed - 260 - 400m/min
• Turning insert feature:
  • Strong cutting edges best reliability in hard cuting conditions and long endurance.
  • Geometry of CNMG turning insert is shaped for strong turning.
    
  • Inserts have secured and strongly supported cutting edge.
  • Recommended for different purposes and applications.
• Tips and Tricks:
  
  • For rough turning it is recommended  to use inserts with bigger nose radius (like R0.8 - R1.2), so wear, force and heat is distributed over larger surface - which makes inserts more durable.
    
  • For finishing it is recommended to use inserts with smaller nose radius (like R0.8 - R0.4), with that we reduce preasure on insert, increase cutting abilities, reduce vibration and we make better finishing surfaces.
