Coatings play a crucial role in the performance and longevity of indexable milling inserts. These inserts are used in machining operations to remove material from a workpiece, and coatings can enhance their cutting capabilities and provide protection against wear and other forms of damage.

One of the primary functions of coatings on indexable milling inserts is to reduce friction between the insert and the workpiece. By reducing friction, coatings help to minimize heat generation during cutting, which can lead to improved tool life and increased cutting speeds. Coatings can also provide a smoother surface finish on the workpiece, resulting in higher-quality machined parts.

Coatings can also provide protection against wear and erosion. As the milling insert cuts through the workpiece, it can come into contact with abrasive materials and chemicals that can cause the insert to wear out quickly. Coatings act as a barrier, shielding the insert from these potentially damaging elements and extending its lifespan.

In addition to reducing friction and providing protection against wear, coatings can also enhance the cutting performance of indexable milling inserts. Some coatings have a higher hardness than the insert material itself, which allows them to maintain a sharp cutting edge for longer periods. This results in improved cutting efficiency and a reduction in the need for frequent tool changes.

Another important DCMT Insert role of coatings is to improve the chip evacuation process. During milling operations, chips are APKT Insert formed as the tool removes material from the workpiece. Coatings can help to prevent these chips from sticking to the insert, allowing for smoother chip flow and reducing the risk of chip jamming or clogging.

The choice of coating for indexable milling inserts depends on several factors, including the type of material being machined and the specific cutting conditions involved. Some common types of coatings used on these inserts include titanium nitride (TiN), titanium carbonitride (TiCN), titanium aluminum nitride (TiAlN), and diamond-like carbon (DLC) coatings.

In conclusion, coatings play a vital role in improving the performance, longevity, and cutting capabilities of indexable milling inserts. They reduce friction, provide protection against wear, enhance cutting performance, and improve chip evacuation. The choice of coating depends on the specific machining application, and it is important to select the coating that will provide the best combination of properties for optimal tool performance.

Big-Plus and HSK are superficially similar in some ways. Both of these machining center spindle-and-toolholder interface systems aim to provide a more stable connection than Indexable Threading Insert the typical machining center system employing standard conical toolholders. And both of these systems are roughly equal in price when it comes to purchasing a set of toolholders for a machine. But Cory Cetkovic, applications engineer for Big Kaiser Precision Tool, says the two interface systems actually differ fundamentally in their method of clamping the holder. That difference has important implications.

The Big-Plus system involves elastic deformation of the spindle connection, he says. During clamping, that deformation results in axial displacement of the toolholder into the spindle. Prior to clamping, the toolholder makes only taper contact within the spindle, but after clamping of the retention system, the spindle expands within an elastic limit until the toolholder achieves the second area of contact—contact at Cutting Carbide Inserts the spindle face—that is the defining feature of the Big-Plus system.

HSK, meanwhile, works by elastically deforming the toolholder. Fingers inside the hollow shank of the toolholder clamp the holder by pushing out. High spindle speed helps this interface, because the centrifugal force strengthens this clamping.

In large part because of this very different clamping, these two systems are not equivalent, says Mr. Cetkovic. Big Kaiser supplies hardware for both, including Big-Plus tooling manufactured by Big Daishowa Seiki, the originator of the concept, and HSK toolholders that are hard milled, hard turned and ground after heat treatment for precision, surpassing that of commodity holders. Thus, the company often advises shops considering new machine tools on which toolholder interface to select. The choice depends on the application, he says. It also depends partly on the wishes of the user.

For example, the notion that a set of toolholders for either system is roughly equal in price, while outwardly true, masks a source of savings with Big-Plus that might be important to a given shop. Big-Plus is the system that adds spindle face contact for heightened rigidity to a toolholder interface that otherwise uses the same 7:24 cone of CAT and BT tapers. As a result, standard CAT and BT holders can be used in a Big-Plus machining center, and Big-Plus holders can be used in standard machines. Though the face contact is not realized in either of these cases, a given shop might prefer the Big-Plus system’s freedom to use existing, standard holders in cuts for which the rigidity doesn’t matter.

Testing at Big Kaiser has measured what this rigidity means and what performance it seems to delivers within the range of applications most favorable for this system. Machining tests with a 12-mm four-flute carbide end mill were run on two identical machines (same make and model), one equipped with Big-Plus and the other with HSK. On each machine, the workpiece was milled at various tool overhang lengths to measure the maximum axial and radial depths of cut at which the tool would perform effectively. The graphs on this page show the depths of cut at which chatter set in for each set of parameters. No doubt the different natural frequencies of the different toolholder systems contributed to how deeply a given tool setup could cut without chatter, so clamping stiffness alone isn’t the whole story. Still, at nearly every test run, the Big-Plus system provided for the capacity to take a deeper cut.

But results such as these do have a speed limit, Mr. Cetkovic says. It is the shops moving into higher spindle speeds that ought to consider HSK, partly because of the toolholder’s lighter mass, and partly also because of the very fact that the toolholder in the HSK system deforms rather than the spindle. Again, high rotational speed helps the clamping of this interface.

At around 24,000 rpm, he says, the centrifugal force’s relaxation of the connection for a conical holder, combined with that same force’s strengthening of the HSK clamp, results in the rigidity advantage crossing over to favor HSK from that speed up.
