Topdrill – New DL chip former for mild steel machining The TopDrill line’s current DP chip former is a multi-purpose insert that works wonders on various types of materials. Now TaeguTec has expanded the line’s capabilities by introducing the DL chip former specifically dedicated for mild steel machining applications.

The R&D department then undertook comprehensive practical machining trials, replicating a wide range of turning applications across a variety of metals. This process resulted in further refinements. Only after it became clear that the geometries of the new chipformers represented a major leap forward were the latest products introduced to the market.

For medium machining of steel and using a reinforced cutting edge, the M3P chipbreaker features a positive rake angle to reduce cutting forces and for smooth cutting. The machining application range is 0.5- to 6-mm DOC and 0.15-0.60 mm/rev (Fig. 2).

In addition to the SED4 UL line, TaeguTec has also introduced a complete line of SED4 UR end mills with a corner radius for enhanced tool life and machining performance. The SED4 UL range is available in diameters from 2 to 16 mm with each diameter offering the customer a selection of corner radii. Although the 4 mm diameter tool offers users the choice of a 0.1, 0.2 or 0.5mm radius, the largest 16mm end mill is available with a 0.5, 1, 2 or 3mm corner radius.

Expands StarMill SED end mill series The StarMill SED range of end mills from TaeguTec has been expanded to offer a greater choice of diameters, lengths, radii, coatings and geometries.

Prompted by the global turning industry’s needs, the latest range of chipformers began as concepts that were assessed and developed by finite element analysis programs. This meticulous evaluation and development process ensured the production of a range of advanced prototypes.

Newly designed turning chipbreakers have been specially formulated to decrease the volume of chips removed from the workpieces during the machining process, which consequently provides efficient chip removal from conveyor belts.

DL chip former features The DL chip former is suitable for mild steel and low carbon steel machining due to its improved chip segmenting capability and the application range has been expanded.

In short, chipformers are specially designed geometric depressions located after the cutting edges of turning inserts. They channel the machined chips and produce the desired chip shapes that can be effectively controlled. These efficient chip forms consume less power; they result in reduced heat generation and most importantly they are able to quickly evacuate the work zone.

Suitable for ramp and slot milling applications, Chase2Mill is available in end mill, modular or face mill designations. Initially launched with a four-corner, double-sided 4NHT 06 insert range featuring a 90° entry angle that is suitable for high ramp-down applications, the 4NHT 06 has been expanded and a newly developed 4NHT insert series released.

Globally, many companies are currently enjoying the multiple benefits of using advanced inserts featuring advanced chipformers. Users are reporting that the problem of chips attaching themselves to cutting tools and components has been totally eliminated and that tools are lasting longer and workpiece quality has been improved.

Korean cutting tool manufacturer TaeguTec has recently launched new products with promises that there will be new developments that will be launched at the upcoming EMO 2019 exhibition that takes place in Hannover, Germany in September 2019.

TaeguTec’s 4NHT 06 insert designation has also been launched with the 4NHT 06-ML, which is said to be characterised by its ability to generate low cutting loads and high surface finishes (credit to ground cutting edges that minimise built-up-edge).

Through the use of these new turning inserts and their chipformers, less heat is generated, the problem of chips attaching themselves to cutting tools and components is eliminated, workpiece quality is improved, insert life is extended and productivity gains are achieved.

Already available for use on difficult-to-cut materials such as stainless steel, titanium, Inconel and other high-temperature alloys, StarMill has been extended with the arrival of the SED4 UL range of 4-flute extra-reach end mills. The UL extension introduces end mills in 3, 4, 6, 8, 10 and 12mm diameters with an overall reach from 63mm to 92mm, depending upon the chosen diameter. With a flute length from 10mm to 40mm, this addition to the SED line-up enables manufacturers to access small cavities and difficult-to-reach surfaces.

TaeguTec has also recently released Chase2Hepta, new carbide shim type cutters and inserts XNM(H)U 06 for reliable roughing and finishing of difficult-to-cut materials

The nature of the chips produced in the turning process varies, depending on the material being turned, the type of tool being used, feeds and speeds being applied, and the rate of cutting fluid applied. As the new tool ranges include chipformers capable of satisfying the vast majority of turning tasks and accommodating a wide range of materials, a product code has been applied to each range.

TaeguTec has been supplying both the TT7005 and TT7015 grades for cast iron machining with great success. Now, an additional grade – the TT7025 grade – has been introduced to widen the scope in order to focus on low speed and interrupted cast iron machining.

The new grade has improved abrasion and chipping resistance because of the latest substrates and coatings ensuring excellent performance, stable and longer tool life in low speed and interrupted machining of cast iron. A further advantage of the new grade is it capitalises on recent trends due to its suitability for ductile cast iron machining. Very good surface roughness is achieved due to the GoldRush post-treatment technology. The TT7025 grade’s black and yellow appearance, black on the bottom and top faces and yellow on the sides, helps to easily determine the level of wear to the insert.

In metalworking, a major cause of damage to tooling is chip interference. To help overcome this problem, chipformers are now widely used on cutting tools for the purposes of chip control.

The product line already includes several types dedicated to various materials: The DP for general purposes; The DK for cast iron, as well as the DA for aluminium machining. With the introduction of the DL insert for mild steel machining, customers now have a wider range of chip former options across more material types.

The new turning chipbreakers break the chips into smaller pieces, which enables better workpiece surface finish, prevents chips from tangling around the workpiece during the machining process and simplifies chip removal from the machine.

The F3P chipbreaker for finishing also has positive rake angles for smooth cutting, reduced cutting forces and reduced insert wear, all leading to increased tool life. The finishing machining application area is 0.40- to 2.0-mm DOC and 0.05 to 0.25 mm/rev (Fig. 3).

As a pioneer in the field of chipformer design, ISCAR has a long history of developing and introducing products with advanced chipformers that aid the efficient removal of chips from the tool and workpiece area.

All ranges within the SED StarMill portfolio incorporate unequal flute spacing and a high helix that combine to reduce harmonic effects and vibration during high-speed machining. Furthermore, the polished high-helix flutes improve chip evacuation, while the TT5515 grade coating prolongs tool life, even under challenging machining parameters, says TaeguTec.

The 4NHT 06 corner R range insert has been extended (04R-20R) to meet the wider range of corner radius requirements demanded by today’s industry. Adding to the existing 8mm and 16mm radius inserts, TaeguTec has expanded the line to include a 4, 12 and 20mm radius offering. The extended 4NHT 06 is available with TaeguTec’s ML and M geometry, and the TT8080 and TT9080 grades, which combine to improve cutting load, minimise built-up-edge and generate high surface finish, says the company.

The R3P chipbreaker is for rough machining of steel with reinforced cutting edge. It has a positive rake angle to reduce cutting forces and for smooth cutting. The machining application range is 4.0-12 mm depth of cut (DOC) and 0.4-1.0 mm/rev (Fig. 1).
