Since boring is slower and more meticulous, it adds money to the final price of the fabricated part. Since low-volume production can get expensive, it’s important to reserve CNC boring for only the most critical holes that can’t afford to have deviations.

When choosing an insert grade, the ideal solution is to consult with an expert from a cutting tool manufacturer. Outside of that, some basic concepts can be used to narrow down the available selections. Most cutting tool manufacturers number inserts in a way that reflects their properties. At Sandvik Coromant, for instance, the first number of an insert grade reflects the general category it falls into. The number 4 is used for steel grades, 3 is used for cast iron and 2 is used for stainless steels. Within each category, the final two digits indicate the insert’s hardness, with low numbers signifying harder, but more brittle and high numbers representing softer, but tougher. To find the category of insert needed, it is best for a shop to start in the middle of the list and work up or down the list, depending on performance.

Can increasing productivity and reducing carbon emissions go hand-in-hand? For its high-volume machining customers, Sandvik Coromant offers a tool for data collection and comparison to aid sustainability-minded process decisions.

A drilled hole comes with a lot of variability. After all, the bit is rotating so quickly and experiences a big moment arm as it comes in contact with the material. On top of that, a drill bit’s diameter isn’t exact to a thousandth of an inch, and it will wear down over time.

This 2023 Emerging Leader developed a product in response to a call for help from Yamaha that was a huge hit in the snowmobile industry when it hit the market in 2010. In fact, it is now a common product that most snowmobile OEMs have implemented.

To a varying degree, the trade-off between strength and toughness can be negated through application of the gradient technique. Commonly applied by all the world’s major cutting tool manufacturers, this technique consists of using a higher ratio of Co on the outer layer of an insert than on the inside. More specifically, the outer 15 to 25 microns of the insert receive extra Co, providing something of a “bumper” that allows it to take a bit of a beating without cracking. This allows the insert body to reap the benefits of using a stronger cemented carbide composition.

When geometry is mentioned in regards to inserts, most manufacturers immediately picture macro-geometry, or the physical shape of the component. Micro-geometry, dealing with the microscopic shape of an insert’s cutting edge, is a rapidly developing field that deserves just as much attention.

This parts cleaning company is elevating its efforts to become a technical cleanliness expert, which presents an exciting, yet sometimes arduous, journey. The ongoing education of the team as well as significant investments in equipment and processes attribute to this shop’s success.

Physical vapor deposition (PVD) is another process used to apply insert coatings. PVD technology creates much thinner layers than CVD. This results in a sharper cutting edge and achieves a benefit in applications dealing with difficult-to-machine metals, such as hardened steels, titanium and heat resistant super alloys.

The materials begin to look a bit more like an insert during the next stage, where they are mixed with polyethylene glycol (PEG)—a plastic agent that temporarily holds them together in a paste form. Press dies then form the materials into the shape of inserts. Depending on the specific technique, single-axis pressing can be used or multiple-axis pressing can shape the insert from different angles.

Verisurf’s Machine Tool Probing (MTP) suite is an in-process automated inspection solution for CNC machine tools, offering inspection and reporting capabilities.

Until recently, the application of TiN marked the completion of an insert. In recent years, a final process has become somewhat widespread. When an insert begins to cool from the CVD or PVD process, the various materials within it contract to differing degrees. Because of this, stress is introduced and small micro cracks appear within the layers. An advanced technique of blasting the insert with a mixture of alcohol, aluminum oxide and fine sand has been found to relieve these stresses and minimize micro cracking. Once this blasting has been completed, a finished insert exists.

Machine tools capable of performing multiple functions and machining parts to completion are becoming the standard rather than the exception. Incorporating automation into these systems allows for extended periods of operation without the need for operator intervention.

Don’t let the name fool you, CNC boring is a very interesting topic. In this post, we’ll be discussing everything about precision CNC boring, how it works, and why it matters to you. When it comes to fabricating precision parts, machinists will often use CNC boring to get nearly perfect dimensions for internal holes and features.

CNC stands for computer numeric controls. It means that the machine in question is using computers and perhaps some automation to run the machine. A non-CNC machine requires the machinist to hand-measure, position, and operate the machine. A CNC version can be controlled with a touchscreen and buttons instead.

Lastly, if an insert is not performing optimally, evidence already exists that can help to determine a solution. Looking closely at the cutting edge with an eyeglass can reveal the nature of the problem. When examination shows that an insert edge is experiencing significant abrasive wear or small deformations, a harder grade is required. If chipping is occurring and small pieces are missing, a softer, tougher grade will likely remedy the situation. By understanding how inserts are created and how different grades are tailored to specific applications, much can be done to boost productivity and reduce costs.

From a decision-making standpoint, one of the most important things to remember about inserts is the significance of aspects that cannot be seen. Even under careful scrutiny, the difference between a high quality and low quality insert might be unidentifiable without testing. Substituting cheap inserts because they look the same will inevitably lead to increased costs down the road.

Coating layers vary in thickness (depending on the application for which the insert is being optimized) for the best wear resistance and thermal and chemical stability.

Mike Medeiros, production manager at North Easton Machine Co., has been advocating CNC Swiss lathes for years, attempting to persuade his local high school’s administration to add the technology to the school’s machining program. Finally, his efforts paid off.

Altering the ratio of WC to Co provides another means of manipulating the properties of an insert. Co is a much softer and tougher material than WC, so decreasing its proportion will result in a harder insert. Of course, this again presents the trade-off where a harder insert will have more wear resistance, but also be more brittle. Choosing the proper grain size of WC and ratio of Co for a specific type of application requires a level of scientific knowledge that could fill volumes.

Ceramics tend to be more brittle than other materials, and defects occur somewhat regularly. The inclusion of properly oriented SiC whiskers significantly slows down the deterioration of the insert, as it takes much more energy for a micro crack to traverse the aligned whiskers. As this and similar technologies continue to develop, ceramic inserts will become a more viable solution for a range of applications.

On the macro level, insert geometry deals with determining the best possible shape for chip control. Depending on the material and application, different shapes and angles will provide optimal results in breaking chips and efficiently transporting them away from the cutting zone. Macro-geometry is a well-established field that most major cutting tool manufacturers have mastered.

Only recently have developments in technology reached the point of enabling control of an insert’s micro-geometry. Using very advanced processes, the cutting surface of an insert can be given a round, oval or angled edge. Microscopic chamfers, or grooves, can also be introduced into an insert’s edge. As innovations in honing and measurement have enabled this level of detail, significant benefits in insert life and stability have emerged. It is safe to say that further technological advances will drive further development in the field and even more substantial achievements will occur.

Ceramic inserts are created in a process very similar to that used for cemented carbide. Because ceramics do not bond as easily as other materials, much higher temperatures must be used during sintering. High pressures are also used.

When it comes to boring machines, the important part of the CNC is its ability to digitally determine positions and automatically move the cutting head around to get the perfect position.

An average shop goes through thousands of inserts in any given year. Every day, an operator might handle dozens of inserts, never thinking about the complicated science behind them. A basic knowledge of what goes into an insert can do more than just provide trivia with which to impress people around the shop.

Zeiss Quality Innovation Days brings together quality and metrology experts from all over the world to take part in industry-specific sessions.

In a typical CVD process, the first layer of coating applied to an insert consists of titanium carbon nitride (TiCN). This material offers excellent wear resistance and has the added benefit of easily bonding to cemented carbide. Typically, aluminum oxide (Al2O3) is used for the second coating layer. Al2O3 possesses the benefit of being very thermally and chemically stable, protecting the insert from high heat and exposure to chemicals found in coolant.

Once pressed into the proper shapes, the pieces go into a giant furnace to be exposed to high levels of heat for sintering. This melts the PEG out of the mixture and leaves behind semi-completed cemented carbide inserts. As the PEG leaves the mixture, inserts shrink to their final size. This step of the process requires considerable mathematical calculations, as inserts will shrink different amounts based upon their composition and the final products have tolerances in the lower single-digit micron range.

On the other hand, boring tools are specifically designed to be highly accurate, repeatable, and operate with minimal chatter.

User-friendly inspection software for CNC machining centers was shown at IMTS 2024 monitoring measurements between and after machining while performing SPC based on recorded measurement values.

The easiest way to change the properties of cemented carbide is through the size of the grains of WC being used. Large grains, in the range of 3 to 5 microns, will create a softer material that wears more easily. Small grains that are less than 1 micron result in a harder material with more wear resistance, but that is more brittle, as well. For applications in very hard metals, an insert with small grains would most likely be best. At the other end of the spectrum, larger grains are preferable when dealing with interrupted cuts or other situations requiring a tougher insert.

Once the specifications are determined for the raw materials, the process of actually creating an insert can begin. Powders of tungsten, carbon and cobalt are placed in a mill approximately the size of a washing machine. This process mills the grains to the necessary size and provides even blending of materials. Alcohol and water are added to the mix during the milling, and a thick, dark slurry is produced. The slurry is then placed in a large cyclone dryer that evaporates the liquids and leaves an agglomerate that is reduced back to powder and stored.

This new vertical turning center with measurement and robotic automation processes is able to produce vehicle ball joint ball pins in 7 seconds.

When it comes to precision machining, the difference usually lies in what the final dimensions are, and how much deviation there is from the dimensions on the 2D designed part. High-precision machining aims to get within a few thousandths of an inch (0.001”) of the designed part. Standard machining might allow for tolerances as loose as 1/32 of an inch (0.0313”) or bigger.

While trochoidal milling might be a more well-known toolpath strategy, trochoidal turning can offer similar benefits such as high material removal rates especially for rough-turning operations.

Production Machining’s October 2024 technology showcase includes some of the latest technology from Ceratizit, Kennametal, Mate Precision Techologies, Horn and Mazak.

As with all man-made items, creating an insert begins with the raw materials, or ingredients. The majority of today’s inserts consist of cemented carbide, which results from a combination of tungsten carbide (WC) and cobalt (Co). The hard particles within the insert are WC, while Co can be thought of as the glue that holds the insert together.

Once TiCN and Al2O3 have been applied, an insert is very close to being functionally complete. Unfortunately, Al2O3 is completely black in color, making it extremely difficult for users to tell which sides of an insert have been used and how the cutting edge has held up. To work around this problem, most manufacturers apply a final coating of titanium nitride (TiN). Bright gold in color, TiN serves no purpose other than providing a highly visible means of assessing a used insert’s condition.

CNC boring is a high-precision manufacturing step that comes after a hole has been rough-drilled. It’s used to make parts with very accurate hole diameters that can be repeated hundreds of times.

The amount of TiCN and Al2O3 applied depends upon the type of application for which the insert is to be optimized. When turning hard materials, for instance, substantial protection is needed, and layers of 10 micron of each material might be used. For finishing applications in softer materials, applying a 5-micron layer of TiCN and 2-micron layer of Al2O3 may be more appropriate.

To keep it simple, think of CNC boring as a much slower, more accurate version of drilling a hole. It’s almost exclusively used on pre-drilled, “rough” holes in a piece of material. These rough holes can be made through a casting process, a drill press, or even a mill.

At this point, the products bear a striking resemblance to finished inserts, but must still have coatings applied to maximize performance. The most common process for applying a coating is chemical vapor deposition (CVD), whereby a metal is ionized through high electrical currents and then applied to the insert via vapor condensation. The process can be visualized as ice forming on roads when the blacktop has become extremely cold and the air contains a high amount of humidity. However, instead, the relatively cool inserts are placed in a furnace that can exceed 900°F.

Recent testing has shown that thread rolling can be more economical than thread cutting when producing 4,000 parts or more. A newly created calculator can help you to determine which might be the better option for your threading applications.

If you take a standard drill press and drill ten holes into a piece of metal, you’ll notice a lot of variability on a microscale. As the tool bit chatters and dances around, holes will become nonidentical and can even become oblong. With CNC boring, this doesn’t happen.
