JOY introduced the world's first large-feed milling cutter, the RD type, which has taken the world by storm in the high-efficiency machining of difficult-to-machine materials such as mold steel and stainless steel.
At present, with the development of machine tools in the direction of high speed and low torque, this type of large feed and small depth of cut machining gradually favored, and gradually become the preferred process in the field of high-efficiency rough machining. And the world's major tool manufacturers in order to cope with the ever-increasing efficiency requirements, but also manufactured a variety of dazzling fast feed tools.
As a large feed small depth of cut tool pioneer, with many years of experience JOY CUTTING TOOLS continue to develop the new product series shown in the figure below, SKS series and QM/QMAX series products as the industry's modern leaders, whether it is the mold processing industry, or increasingly prosperous aerospace field, or the traditional parts industry, are occupying an extremely important place.
Today, JOY CUTTING TOOLS breaks through the traditional concept once again and releases the epoch-making and revolutionary new product - [EXSKS] series, which brings the unprecedented new vision of machining.
In the nearly 50 years since the birth of fast feed tools, although there are a variety of edge design and coating applications, whether it is the machining efficiency or service life are gradually improved, but there has been no qualitative breakthrough in the application of occasions.
The most typical situation, when the use of fast feed tool processing to the side wall and the bottom corner, because of the fast feed special edge structure, processing will leave a certain amount of residue, at this time it is necessary to add a right-angled tool to complete the root of its clean up the end of the work. Although the efficiency of traditional fast feed tools is very high, but it has never been able to break through the shackles of this design structure.
EXSKS", not only in the traditional fast feed machining invincible, but also break the traditional barriers, but also in the square shoulder milling in the ease of use, to achieve "a blade two mode".
How did it make this breakthrough? Below, this article here to unveil its mystery!
The same insert can be transformed into a fast feed tool → square shoulder milling cutter by changing the cutter body!
This double-sided trigon insert has multiple uses. Not only is it a high feed insert, but it can also be used as a 90-degree square shoulder. The maximum depth of cut when high feed machining is 2mm. Even though it is a negative geometry, it is very free machining on the spindle load. This insert likes a heavy chip load and is capable of feed rates up to 500 IPM. available in modular head, solid end mill and face mill styles.
Feature 1
2 types of holders are available using the same insert:
HF type for high feed machining Max. depth of cut (Ap) = 2mm is possible
SM type is for shoulder milling, face milling, vertical wall milling and corner milling
Feature 2
Economical double-sided insert (6 corners)
High efficient machining achieved due tomulti blade specifications
Feature 3
The dovetail-shaped binding face in the pocket prevents movement
of inserts which occurs by cutting force with a single screw.
Feature 4
2 insert grades available:
PVD coated grade “YCP150 achieves both fracture toughness and wear resistance
PVD coated grade “YCP118 provides high versatility and can be widely applied togeneral steel,
mold steel and high hardened die steel less than 50HRC
INSERTS：
Double-sided blade design
The unique design concept of "EXSKS" has resulted in the first-ever double-sided, 12-edged blade among W-type blades, which not only makes it easier for users to manage their tools, but also reduces waste and environmental values by making the best use of the blade.
The inserts are fastened with a unique double-slanting wedge structure,
which allows the inserts to be tightly fixed to the cutter body with just one fastening screw,
effectively suppressing insert fluctuation caused by cutting resistance and realizing stable, long-life machining.
BODIES：
"Practice is the only criterion for testing the truth". Although "EXSKS" breaks new ground in terms of design concept, can it pass the test in actual machining? The graph below shows a parallel comparison test between the EXSKS HF and a similar product from another company in fast-feed machining.
It can be seen from the figure, in the processing material, processing equipment, processing parameters and other conditions are the same, D company products in the processing of 110 meters has been serious wear, while the "Double Magic Shinkansen" processing to 120 meters, the rear cutter surface is still normal wear, can still continue to use.a'w
The graph below shows the cutting performance and machining quality of "EXSKS" SM type in sidewall machining.
As we can see from the example in the figure, although the insert of "EXSKS" is of M grade,
the difference between the height of the joint and the height of the cutter can be as high as 5 μm in sidewall machining,
which is a very impressive performance.
It can be seen that in actual processing, "EXSKS" not only has a clear advantage in terms of longevity,
but also has a functionality that goes beyond theory and can be tested in practice.
After comparing the cutting life performance of EXSKS with that of other companies' products with various functions, the following is a typical example of how EXSKS has revolutionized the scope of fast-feed tooling by switching freely from fast-feed machining to step-over shoulder milling. This is a typical example of how the range of fast feed tools can be revolutionized.
As you can see from the example in the picture, "EXSKS" can easily remove the residual amount (splice difference) with the same insert, and leave an even amount for subsequent finishing, thus ensuring higher accuracy in finishing. Furthermore, "EXSKS" truly utilizes every edge of the insert. The substantial reduction of machining tool waste, in the long run, is undoubtedly a cost reduction, improve efficiency!

We believe that in the near future, "EXSKS" will sweep through the cutting tool industry like a storm, and JOY CUTTING TOOLS will uphold the spirit of "breakthrough innovation, never stop" and "faster (high efficiency), higher (high precision), stronger (long life)" to bring more epoch-making products to every user. JYC will uphold the spirit of "breakthrough innovation, never stop" and "faster (high efficiency), higher (high precision), stronger (long life)" to bring more epoch-making products to every user, promote the technological development of the cutting industry, and let every user experience the perfect feeling brought by technological innovation.
