Coated Grade for Stainless Steel Turning MC/MP7100 Series
Mitsubishi Materials has the ability to combine coating and substrate technology to produce a series of grades to successfully machine stainless steels.
The All-Rounder for Stainless Steel Turning
MC7125
Incredibly stable with both plastic deformation and chipping resistance
MC7125, recommended as the first-choice grade as an all-round performer for turning stainless steels and covers a wide range of modes from continuous through to intermittent machining.
The tool life has doubled compared to previous inserts.
For High Speed Turning
MC7115
Increases the hardness of the base material, providing excellent resistance to plastic deformation and crater wear
Specialized in high-speed machining, MC7115 can reduce cycle times for medium to large-sized batches of austenitic stainless steel parts under high-speed machining conditions of 250 m/min or more.
Tougher for Interrupted Cutting
MP7135
The highly heat resistant coating and dedicated carbide substrate provide both wear resistance and chipping resistance.
MP7135, a PVD coated grade that uses a tough base material is ideal for intermittent machining and therefore vastly reduces damage by the impacts caused during this type of machining. It is ideal for applications when machining forged and cast materials.
Application Examples
Impeller SUS316L / Face Turning
Tool life was improved even on workpieces with severe interrupted cutting.
The optimized long neck maintains rigidity while avoiding interference with the workpiece.
The long neck square types VQ3XL and VQ4XL have a micro gash land geometry that minimizes residual material in the corners of the workpiece, while also increasing the strength of the tool by suppressing chipping.
The long neck corner radius type VQ4XLRB has an optimized cutting edge chip pocket geometry that achieves excellent chip evacuation.
End mill, 5 flute, Irregular pitch flutes, Chipbreaker
Chipbreaker Function
Prevents chip problems by combining great chip breaking capabilities and fracture resistance.
Chip Pocket Geometry for High Efficiency Machining
The rigid cross-sectional geometry with excellent chip evacuation properties is ideal for high efficiency machining such as trochoidal milling.
132 items have been added that will increase the range of cutters that can utilize the MV series of inserts.
MV1020 has excellent wear and thermal shock resistance and thereby achieves stable cutting at unprecedented cutting speeds when machining steel and ductile cast iron. This also greatly reduces cycle times.
MV1030 has excellent thermal shock resistance and improved machining stability even during intermittent cutting, wet cutting and is effective when machining stainless steel where thermal cracking is likely to occur.
By replacing the insert on a single holder, various applications such as grooving, chamfering and thread cutting can all be realized.
A high-rigidity design that securely clamps the insert with 6-sided restraint from 3 key grooves. A simple operation to change the insert with only one front screw maintains the secure clamping and enables stable machining with reduced chattering and vibration.
The holder is available in carbide or steel. In combination with an internal lubrication type SLV sleeve holder, a large amount of high-pressure coolant can be supplied for effective chip removal.
for Low Depth of Cut and High Feed Finishing FPH Chipbreaker
The FPH Breaker was the result of the extensive development with a geometry that optimizes chip control at low depths of cut and feed conditions.
A combination of the positive land geometry and the unique two-step protrusion optimizes chips under low cutting conditions and therefore reduces machining time.
Chipbreaker with Depth of Small Cutting for Hard-to-cut Materials FSF/FSF-P Chipbreaker
The 25° rake angle gives increased sharpness, and the low-resistance design of the small breaker protrusion provides excellent finished surfaces of components.
It is a multi-stage breaker that is resistant to variations in cutting depth and can be used for all types of workpiece geometries.
Also available is a polished type with a mirror finish of the rake surface of the insert, which greatly improves adhesion resistance and achieves the very best component surface finishes.
