Efficiency and cost reduction may be missing!

In recent years, with the development of processing machine tools and IT technology, the manufacturing site has changed dramatically. Manufacturers want to further increase productivity through machining, such as: 1) shorten lead time; 2)

reduce machining costs; 3) improve machining quality; in response to this series of requirements, improvements and upgrades are needed in all aspects.

We as a professional cutting tool R & D, manufacturers, has been committed to the user's requirements and ideals into reality. In this article, we will combine the economic (cost reduction) and high-precision machining (quality improvement)

requirements of users, and proudly introduce [EXSIX] square-shouldered milling tools that can realize high-efficiency machining (shorten delivery time)!

EXSIX specificities

The EXSIX-6 utilizes a unique 3-dimensional, low resistance type chip breaker insert with the following features:

・Economy: In order to further reduce machining costs, the inserts are designed to be used on both sides, allowing a total of 6 edges to be used.

・High efficiency: High efficiency machining is realized by the feature of axial maximum depth of cut up to 10mm.

・High rigidity: The thickness of the insert is 7.5mm, which greatly improves rigidity compared to conventional products, and enables stable machining in rough machining areas.

・High precision: The peripheral cutting edge has a rounded design, which effectively suppresses the height of the contact even with a large axial depth of cut, and realizes high-precision wall machining.

In addition, the inserts are available in YCP150, which has excellent chipping resistance for machining normal and pre-hardened steel, and YCP118, which has excellent wear resistance for machining cast iron, hardened steel, and other materials. Both inserts are available with R0.8 and R1.6 tip rounding for a wide range of machining forms and materials.

EXSIX Body Characteristics

As mentioned above, the insert adopts a unique 3-dimensional low resistance chipbreaker groove design, and the cutter body adopts a positive design with a positive axial inclination angle (axial forward angle), which cannot be realized by the usual double-sided negative angle inserts. This enables low cutting resistance machining and extended tool life. In addition, the chip removal performance is improved, and problems such as chip bite are reduced, realizing stable, long-life machining.

In addition, the high rigidity design of the cutter body, optimized by stress analysis, can withstand high loads during rough machining. As a result, the tool can be used not only for square shoulder or vertical wall machining, but also for surface cutting, groove cutting, tilting plunge cutting, and insert milling.

The machine used is a BT50 vertical machining center.

Tool used:

Tool model: EXSIX-5063R-22

Blade model: YCMU090708ZER-PM

Blade material: YCP150

Machining conditions:

Cutting speed Vc=180m/min.

Feed per cutting edge fz=0.3mm/t.

Axial depth of cut ap=3mm.

Radial depth of cut ae=40mm.

Tool overhang length L=140mm (L/Dc=2.2) .

Smooth milling with only 1 insert loaded for testing.

The above chart shows the results of a 3-point force comparison between EXSIX and our conventional products and equivalent products from other companies.

In the comparison of main parting forces, EXSIX is 95% of our conventional products and 74% of similar products from other companies. This is the result of the perfect combination of a unique 3-dimensional, three-dimensional type chipbreaker insert and an axis-forward angled cutter body, which effectively reduces cutting resistance, resulting in stable and highly efficient roughing under high-load machining conditions.

Axial depth of cut ap=3mm.

Radial depth of cut ae=40mm.

Tool overhang length L=140mm (L/Dc= 2.2).

Smooth milling, only 1 insert was loaded for testing, blow cooling.

The above chart shows the verticality measurement results of EXSIX, and our traditional products, and equivalent products from other companies.

EXSIX realizes high precision wall machining by achieving excellent chip evacuation with its unique positive angle type design and its unique arc type peripheral cutting edge design.

On the other hand, the equivalent products (double-sided inserts) from other companies have poor chip evacuation due to the negative-angle design, and chips adhere to the machining wall (below), resulting in poor machining accuracy. EXSIX is a roughing tool, but it can effectively reduce the burden of the subsequent finishing process, and it provides the most effective and stable basis for realizing the requirements of productivity improvement such as shortening the delivery time, reducing the machining cost, and improving the quality of products. It provides the most effective basis for realizing the requirements for productivity improvement such as shortening the delivery time, reducing the machining cost, and improving the quality of products.

The following is an example of an improved machining process using φ50EXSIX for rough machining of a stamping die.

Use the tool:

Tool model: EXSIX-4050R-22

Blade model: YCMU09070808ZER-PM

Blade material: YCP118

Material to be processed: cast iron FC250

In this type of machining, the machining load is high due to grooving, and the insert and insert locking screw are often easily damaged, making stable machining difficult.

However, the EXSIX has been highly praised by users for its stable machining without the problem of broken inserts and screws, and for its high chip discharge capacity of 160 cm3 / min, which realizes stable and efficient machining.
