An exchangeable head range of end mills has obvious advantages for reducing inventory levels and tool change times. Additionally, they are capable of high performance over a wide variety of applications.

A key feature is the double face contact of carbide head and holder that enables security and rigidity close to that of a solid type end mill. This is made possible because the taper and end clamping faces of the head and the holder are both solid carbide and only the threaded part is composed of steel. Benefits of this secure and accurate clamping method when compared to the usual steel to carbide method are greater efficiency from increased cutting parameters, improved accuracy and the all-important factor of reliability.

The outstanding crystal orientation of the Al₂O₃ coating has been developed by improving the conventional nano texture technology. These technological improvements increase both wear resistance and tool life. In cutting trials of interrupted cutting on DIN 41CrMo4 material, the tool life of MC6135 was found to be extended by 20% compared to conventional grades.

Allied Machine & Engineering, a leading manufacturer of holemaking and finishing cutting tools, has announced the release of the M geometry insert for the GEN3SYS XT Pro high penetration replaceable insert drilling system.

From 30-31 October, ITC will again be exhibiting at the Advanced Engineering Exhibition on Stand T171 in Hall 3 at the NEC Birmingham.

A mono-block type holder greatly reduces tool overhang, compared to standard milling chucks and also allows stable machining even with larger diameter tools, thereby achieving higher efficiency machining.

When a standard milling chuck is used, a screw-in type shank is required, which is also negated when using a mono-block type holder, therefore a reduction in costs can be realised. An added feature is the undercut at the bottom of the neck, making it suitable for vertical wall machining.

The popular MC6100 range of inserts from Mitsubishi Materials has been expanded to include MC6135, a tough grade for applications ranging from continuous turning through to rough and interrupted cutting.

A new range of electrically actuated swing clamps capable of generating high forces for securing workpieces during machining has been introduced by Roemheld UK.

Another product launch from Mitsubishi Materials is a dedicated range of tool holders to complement the large range of geometries and types available in the iMX series of solid carbide exchangeable end mills.

Nearly 85% of small to medium-sized manufacturers (SMEs) are calling for more government funding to help them bridge the digitals skills divide, it has been revealed.

The new MC6135 insertThe popular MC6100 range of inserts from Mitsubishi Materials has been expanded to include MC6135, a tough grade for applications ranging from continuous turning through to rough and interrupted cutting. This new grade will complement the existing range and provide end users with a choice to machine a vast array of steels and of different applications. MC6135 incorporates crystal orientation control technology that enables thinner but still impact-resistant coatings that provide improved chipping and wear resistance. Such features are optimal for use on the tough MC6135 grade. Additionally the coating is 50% thinner compared to previous types.The outstanding crystal orientation of the Al₂O₃ coating has been developed by improving the conventional nano texture technology.

An added feature is the undercut at the bottom of the neck, making it suitable for vertical wall machining.The manufacturer sees the  iMX series as a revolutionary end mill system that combines the advantages of both solid carbide and indexable end mills. Significant performance advantages and savings can be gained especially when long overhang applications are required. The cost of extra-long solid carbide end mills is negated by using exchangeable heads. It is this interchangeability that also reduces tool change times because the head can be simply unscrewed rather than unclamped from a chuck or shrink fit holder as a conventional end mill would be.The BT 30 Holder Taper Neck TypeA key feature is the double face contact of carbide head and holder that enables security and rigidity close to that of a solid type end mill.
