Mitsubishi Materials Corporation, Advanced Materials & Tools Company (President – Fumio Tsurumaki, Headquarters: 1-3-2 Otemachi, Chiyoda-ku, Tokyo) has launched new small diameters, φ50 mm and φ63 mm sizes for the FMAX high feed finish milling cutter.

A special alloy steel and aluminium body in the FMAX cutter combine to provide rigidity and light weight. FMAX offers super efficient machining through the adoption of an ultra fine pitch tooth design. This helps to achieve high efficiency machining of F≧20m/min. (Tool diameter 125mm, 24 teeth, when machining a non-ferrous metal such as aluminium alloy.) FMAX delivers high efficiencies and is especially effective for high feed machining of automotive parts. To complement the existing sizes, the range has now been expanded to include smaller sizes, φ50 mm andφ63 mm.

Features of the FMAX cutter

• The body protector on the rake face forms chip shapes that are ideal for disposal and disperses them away from the body. Internal coolant also aids this process.
• A special alloy steel and aluminium body combine to provide rigidity and light weight. FMAX also features an anti-fly dovetail clamping mechanism.
• The combination of both large and micro adjustment screws provides the ability for a precise run-out setting (5ɥm or better).

Mitsubishi Materials Corporation, Advanced Materials & Tools Company (President – Fumio Tsurumaki, Headquarters: 1-3-2 Otemachi, Chiyoda-ku,Tokyo) has added an radius type to the MS plus solid carbide end mill series.

MS plus end mills are regarded as tools with a stable tool life when machining a broad range of workpiece materials up to 50HRC that are commonly used in the mould and die industry. Now the MS plus end mill series has been further expanded to include a new type, MPMHVRB, a 4 flute corner radius end mill with irregular helix flutes. Additionally 2 square corner types, with an external diameter of 16 mm and 20 mm have been added. Both are suitable for high efficiency machining of stainless and carbon steels.

Features of MPMHVRB of MS plus end mills series

• MS+ coating is used because it displays excellent wear resistance over a broad range of workpiece materials from carbon steels through to hardened steels up to 50HRC.
• It delivers overwhelmingly high vibration resistance by adopting flutes with different helix angles. This helps reliability when machining long overhang applications.
• MPMHVRB provides a wider general-purpose use because both the cutting edge and overall length are slightly longer than conventional products.

For high performance cast iron turning, Mitsubishi Materials has now extended its renowned MC5000 series of turning inserts for cast iron with the launch of several new geometries for the MC5005 and MC5015 CVD coated grades.
MC5005 introduces an innovative new ultra thick Al2O3 layer that is twice the thickness of conventional coatings. This combines with a TiCN nano-texture layer that is bound by Mitsubishi’s patented “Tough Grip Technology”  to outperform conventional carbide and ceramic grades when conducting continuous cutting of grey cast iron. This ultra thick layer prevents the coating from peeling and eliminates edge chipping that is a common occurrence with competitor grades. Working in tandem with an enhanced
carbide substrate, the result is significantly improved tool life and surface finishes together with greater process reliability and reduced tooling costs.
Complementing MC5005, the MC5015 series is composed of the same substrate and coating layer technology as the MC5005, but has been developed for interrupted machining
applications. With a thicker TiCN layer than MC5005, the MC5015 series has an ideal distribution of hardness and toughness that provides extreme plastic deformation
resistance nearer the surface whilst delivering overall toughness to prevent insert breakage under heavy loads during interrupted machining. The result remarkable performance and tool life through prolonged wear resistance.

The new inserts, as with the whole range, are available with Mitsubishi’s LK, MK and RK chipbreaker designs and also available with a flat top geometry for unstable
cutting and for cast iron with a thick layer of skin. The LK chipbreaker provides a positive land with a sharp cutting edge to provide low cutting resistance whilst the MK chipbreaker incorporates the optimal balance between edge sharpness and edge strength for more general cast iron applications. Furthermore, the RK chipbreaker has tripled the conventional ratio of the seating area and land width to enhance stability when conducting intermittent machining and when removing scale.
To simplify the insert selection process for the end user, Mitsubishi has introduced its new Easy Selection Breaker System. The chipbreaker designations are broken down in to L, M and R for Light, Medium and Rough machining whilst the K designation identifies the ISO material specification. This innovative yet simple approach provides the customer with clarity and simplicity when identifying the required insert grade and chipbreaker types. The grades and chipbreaker designations are also provided in tabulated format to further
facilitate the insert selection process.

Mitsubishi Materials Corporation, Advanced Materials & Tools Company has launched three new types of chipbreaker for the cermet grade NX2525 that is suitable for turning steels and cast iron materials.

Cermet grades are ideal for finishing and light cutting due to their excellent in high temperature hardness when compared with cemented carbide. Additionally it is able to maintain high quality surface finishes.

NX2525 has highly hardened Ti compound particles within its microstructure therefore the grade has both excellent wear and fracture resistance properties.

To allow a wider range of chip control, the FY breaker for mild steel finishing, plus the SY breaker for light cutting and also the SA breaker for carbon and alloy steels light cutting have been added to the NX2525 range.

Features of FY, SY and SA breaker

1.The new three breakers cover copying and back turning due to the wavy edge design.

2. The FY breaker effectively controls adhesive chips and is suitable for finishing mild steel.

3. The SY breaker effectively controls adhesive chips and is suitable for light cutting of mild steel.

4. The SA breaker offers superior chip control at small depths of cut when light cutting carbon and alloy steels.

Mitsubishi Materials Corporation, Advanced Materials & Tools Company (President – Fumio Tsurumaki, Headquarters: 1-3-2 Otemachi, Chiyoda-ku, Tokyo) has added BC8110, a coated CBN grade for the GY series grooving system.

The existing GY Series has received a favorable reception as a grooving system that offers the ultimate in rigidity with a unique clamping technology called TRI-LOCK. This modular type holder system realizes high efficiency machining.

The coated CBN grade BC8110 prevents linear crack development that can cause sudden fracturing and achieves a stable tool life when turning high hardened steels. This new grade has been added to the GY series to complement the existing range of grooving tools.

Features of the coated CBN grade, BC8110, for high hardened steel turning

• The newly developed special ceramic coating improves wear and chipping resistance.
• Dispersal of the new Ultra Micro-particle Binder in BC8110 prevents linear crack development that can cause sudden fracturing.
• Improved adhesion to the CBN surface provides increased peeling resistance.
