Sumicarbide AC410K Grade For Cast Iron

SUMITOMO’S NEW AC410K GRADE FOR HIGH SPEED CAST IRON TURNING NOW AVAILABLE

Mount Prospect, IL – Featuring new coating technology, Sumitomo’s AC410K grade consists of two types of coating layers – the Super FF Alumina layer and the Super FF TiCN layer – both of which provide excellent peeling resistance and improved overall insert stability.

Its ultra-thick, inner Super FF Alumina layer provides exceptional thermal resistance, while the outer Super FF TiCN layer excels in chipping resistance.  The grade combines these coatings with an exceptionally hard carbide substrate, resulting in excellent wear resistance in continuous to light interrupted machining of gray and ductile cast iron.

Additionally, the excellent wear resistance and superior toughness of the AC410K have at least DOUBLED the tool life of conventional cast iron grades. Consisting of a wider application range, the AC410K is capable of covering medium to high-speed machining applications.

The AC410K grade is available in positive insert styles for light to medium cutting applications and negative insert styles for light to rough cutting applications.

Iscar Hydraulic Chucks – Hydrofit

ISCAR HYDRAULIC CHUCKS COMBINE PRECISION, EASE OF USE

New HYDROFIT hydraulic chucks from ISCAR not only qualify for high speed machining (HSM) but also simplify tool changing, presetting and fine balancing more than ever before.
Suitable for stationary- or rotating-tool applications of up to
15,000 RPM, HYDROFIT chucks deliver the clamping force, accuracy, dynamic balance and vibration damping necessary to protect brittle solid carbide round tools in HSM work. Runout accuracy is 0.003 mm.
ISCAR’s hydraulic chucks require only moderate hand torque on an Allen key to clamp and unclamp the tool – right in the spindle. The turn of an internal preset screw adjusts the datum to where you want it. Optional threaded holes facilitate fine balancing.

HYDROFIT chuck styles are available suit all popular HSK, DIN and SC machine interfaces and to handle four main shank types:
• Taper shanks for rotating applications
• VDI DIN 6980 shanks in sizes 30 and 40
• ST 25, 32 FINEFIT ADJ with 070 flange for stationary tools
• FINEFIT ADJ taper shanks with 070 flanges for rotating tools

Crystallume Lightning Series End Mills

Crystallume has introduced a new diamond coated tool.  They call it the Lightning Series.  Here is what they have to say about it:

“The Lightning Series has about half the thickness of our standard diamond coating.  The reduced coating thickness gives up tool life for edge sharpness and lower cost, due to reduced time in the coating chamber.

The Lightning Series is available in common standard fractional sizes, in both square, corner radius and ball ends.”

Machining Cast Iron with CBN

CBN can provide a cost effective and highly productive alternative to hard metal or ceramic cutting tools for the machining of cast irons. In general terms, the following factors should be considered when applying CBN to an iron component:

Cast iron is not generally very hard (less than HRc.30) but tends to be abrasive. CBN is therefore employed because of its abrasive resistance. Unless the iron has been chilled or deliberately heat treated, the cutting action will be such that the CBN will not be required to anneal the material being cut in the shear zone. Grey cast irons are often fully pearlitic in structure – Grade 14 & 17 are common. In this case, the best results are gained using DR – 100/80 at surface speeds above 400 m/min. if the machine tool or component limit the speed available to less than 400 m/min, DR – 50 becomes more cost effective.

Tool life and component quality improvements are often dramatic and more than justify the increased cost of the CBN tools. if the grey cast iron is not fully pearlitic and more free ferrite is present within the structure, the machinability of the iron becomes more difficult to predict. As the level of “soft and sticky” ferrite increases, the tool is more likely to suffer adhesion pick up which will alter the cutting action, resulting in premature wear of the tool. DR-50 becomes more likely to provide good results as the level of free ferrite increases and a short trial will soon determine the most suitable PCBN material.

Fully ferritic grey cast irons are not generally cost effective PCBN applications. S.G. irons are generally soft (less than HRc.30 ) and fully ferritic. PCBN is therefore not generally as efficient as other cuttingtool materials. There has, however, been a tendency to produce S.G. irons (nodular irons) with a pearlitic structure. This has resulted in some nominally S.G. irons machining surprisingly well with PCBN, DR-50 tending to be more successful. Low alloy irons commonly used in the automotive industry can be machined with CBN, but the performance is again dependant on the level of free ferrite in the structure of the iron.

Hardened irons, either heat treated or alloyed and heat treated, are machined in the same manner as hardened steels and are therefore more predictable. Cutting speeds recommended are lower – less than 200 m/min. It must be remembered that cast iron of a given specification produced by a foundry on one day may have a different machinabilty to that produced the next day. Once the benefits of machining with CBN have been determined, it may be considered worthwhile ensuring that castings supplied to the machine shop have a suitable microstructure to guarantee consistent PCBN tool performance. if the structure or grade of cast iron is unknown, a simple trial will soon determine the suitability of PCBN as a cutting tool.

Sandvik GC4225

GC4225 – the next generation of high-performing first choice insert for general steel turning

GC4225 from Sandvik Coromant represents the next generation of P25 grades to enhance machining performance in the general steel turning area.

Over the past few years, Sandvik Coromant has carried out extensive R&D to establish the new P25 grade, GC4225, which is the next insert generation to make the general steel-turning area even broader, more productive and more reliable.

A multi-talented insert grade for steel turning

In general steel turning everything varies. The steel material varies from un-alloyed to high-alloyed bar-material through to various forgings and castings. The type of operation varies from rough to finish turning with conditions ranging from good to difficult.

GC4225 has an improved capacity to adapt to variations in workpiece material and operational demands towards the tougher end of applications, thus providing more versatility. The new black and yellow grade provides a new potential for increasing productivity through higher cutting data, backed up by improved reliability.

Iscar HeliTurn

ISCAR’s HELITURN system features a unique, double-sided insert with 4 cutting edges for Fast Metal Removal (FMR) turning. The new HELITURN is a tangentially clamped insert with a unique helical shaped cutting edge, useful for large depths of cut and higher than normal feed rate.

The LNMX…-HT HELITURN insert is screw-clamped into the SLANR toolholder and supported by the TLN ..-HT carbide seat. This seat has ground surfaces on the top and bottom, to ensure perfect contact of the insert with the toolholder.

The upper rake face of this insert is mounted level with the top of the toolholder to enable chips to flow across the insert, without being disturbed by clamps or the toolholder body. The 4 curved helical cutting edges ensure positive radial rake angles and soft penetration into the material being cut. The lower forces and smaller loads ensure better tool life, higher stability and the ability to use very large depths of cut and higher feeds. The chipformer (with small bumps), deforms and breaks the chip into rib type curved segments which can easily be removed from the cutting area.

The insert has a frontal clearance angle of 3.7° with a 6° side clearance angle to allow machining to a 90° shoulder.

Depths of cut up to 8 mm [.315”] and facing depths to 3.2 mm [.126” ]
at up to 1.2 mm/rev [.047” IPR] are achievable with HELITURN.
