| Ceramic Inserts vs. CBN Inserts |
| 2008-04-14 10:55:46 |
CNMA CBN Insert (shown in picture above)VS.CNGA Ceramic Insert (shown in picture)An important criterion for the economical application of cutting tools is their life in relation to the metal removal rates, especially with two materials such as ceramic and CBN. The latter is much more expensive. Thus, comparison of tool wear becomes most important.The two materials show marked performance differences in both size and surface finish in roughing, interrupted, and finishing cuts. In comparison to gr...

| A Post About Absolutely Nothing |
| 2008-04-13 21:25:01 |
Ok, so in the title it says that on from time to time there would be an occasional rant about nothing. I haven't faithfully held my end of the bargain on that one. Therefore folks, here you go, a rant about nothing.Over the weekend at our church, I had the pleasure of playing my acoustic guitar with some very talented musicians, in front of a few thousand people. I tell you what, in my life, this was up there with being one of the more difficult thing I've ever had to do. My attempts at pub...

| Inserts for difficult materials |
| 2008-04-02 14:53:31 |
Superalloys are hard; some grades of titanium are machined at 330 Brinell hardness. With conventional alloys, cutting zone temperatures greater than 2,000[degrees]F soften molecular bonds and create a flow zone for chips. In contrast, the heat resistance that makes HRSAs so desirable keeps them hard throughout the machining cycle.HRSAs also tend to work-harden as they are cut, notching cutting inserts to premature failure. The difficulty cutting HRSAs is compounded where unpeeled stock is covere...

| PCD Insert Tooling for Plastics |
| 2008-04-02 14:45:54 |
Plastics and reinforced plastics can be machined with PCD Inserts and PCD tooling. The general perception is that plastic materials are easy to machine. However, soft plastics are not always so stable, and the machining process, which always generates heat, can affect dimensional and material properties like surface texture and colour, if the correct cutting tool is not applied.PCD tools are particulary effective on abrasive plastics where plastics are reinforced with carbon fibres (CF) or ...

| CBN Cutting Tools for Grooving |
| 2008-03-29 12:02:04 |
Hard part grooving can be a difficult process without the correct tools. CBN cutting tools for grooving can ease that process. During heat treatment, many features of machined components suffer distortion. If the position or dimensions of a groove are critical to the performance of a hardened component, David Richards can offer a simple solution to this problem - ‘Hard Grooving’. Based on the Top Notch system, David Richards supply grooving tools in a wide range of sizes from 0.5 mm width ...

| Cnc Milling: a Versatile Process |
| 2008-03-29 11:44:55 |
Author: George UreComputer Numerical Control (CNC) Milling is a common type of automated machining process. These machines are specially used for drilling, facing, and turning functions. Their classification is based on the number of axes they have. These axes are labeled as x and y for the two horizontal directions while z is for vertical movement. CNC milling is a cutting process that is used to remove metal or plastic from a block of stock material by the rotating action of the tool. The tool...

| Using Coolant - CBN Inserts - Interrupted Cutting |
| 2008-03-29 11:43:24 |
Although most of the heat essential for efficient cutting exits with the chip, any increase in the temperature of the component will make accurate measuring difficult. Coolant can be used to reduce this effect.Coolant can be used to drive away any swarf which might interfere with the cutting edge, particularly in boring operations. Coolant can help reduce vibration, especially where rigidity is limited.Where interrupted cutting with CBN inserts occurs, coolant should n...

| PCD Insert Machining Dont's #1 |
| 2008-03-29 11:25:28 |
PCD inserts are not recommended for the machining of Iron, Cobalt, or Nickel alloys. In the presence of these metals and the heat and pressure created by cutting, diamond is encouraged to revert to the metastable carbon form: graphite. It is possible to use PCD inserts to machine some stainless steels and other highly alloyed materials, which have the iron, cobalt or nickel tied up in a non-reactive state. Even so, the...

| Anatomy of a Diamond Coated Insert |
| 2008-03-02 17:16:11 |
The base material, or substrate, for most thin-film coated-diamond inserts is tungsten carbide (grade C-2). It's basically the same substrate material used for many carbide inserts coated with titanium nitride or titanium carbide. A carbide insert is made from two main ingredients, carbide and cobalt, which are mixed together in various ratios and sintered. Carbide manufacturers guard their ratios and sintering process details the way chefs protect their recipes. The carbide used in an insert is...

| Disadvantages of Diamond Coated Inserts |
| 2008-03-02 17:15:37 |
Probably the main weakness of thin-film diamond-coated inserts is lack of toughness. CVD diamond films are brittle when deposited on low cobalt substrates. These inserts are not always robust enough to endure high mechanical shock. They are not always the best choice for heavy metal removal and interrupted cutting. As with most coated inserts, thin-film diamond-coated inserts are "throwaways." They cannot be reground. Predicting the performance of CVD diamond inserts is still somewhat uncerta...

| Purpose and Use of the Cut-Off Tool and Holder |
| 2008-03-02 16:59:56 |
After completing a part in the lathe it is frequently necessary to separate the part from the excess material used for chucking. This operation is best accomplished with the use of a cut-off tool or "parting tool" as it is sometimes called. The Cut-off Tool and Holder consists of a very slender high speed tool steel cutting blade mounted in a special tool holder. The thinness of the blade (.040") enables it to feed into the part quite easily and at the same time minimizes the amount of waste mat...

| Turning Carbon Fiber Composites |
| 2008-02-21 11:58:51 |
What's the best insert for turning carbon fiber composites?At first it might seem that machining fiber-filled composites with hard cutting tools would be a recipe for disaster. Developers of cutting methods and tools for composites face all kinds of problems. A composite's fiber layers can delaminate from the machined surface; the fibers or other hard reinforcements are abrasive and reduce tool life considerably; and the combination of hard and soft materials that make up a composite complicates...

| What is Cermet? |
| 2008-02-20 11:26:54 |
What are cermet inserts?Of uniform structure and composition, Cermet is composed of solid titanium carbide (TiC) and titanium nitride (TiN) with a super-alloy metal binder. Cermet has a low friction coefficient which eliminates built up edge and improves surface finish. Its high resistance to thermal deformation and its low conductivity make higher cutting speeds possible and result in lower flank wear and edge cratering. Its high degree of hardness and toughness, with resistance to oxidation...

| Machining Soft Steels with CBN Inserts |
| 2008-02-04 11:47:55 |
Finding it difficult to machine soft steels with cbn inserts? I would suppose that soft steel is relative, so generally speaking, cbn inserts will machine steels from 45-65 HRc. For soft steels (the ones on the lower end of the 45-65 HRc), the lower you are on the hardness scale, the faster you will want to machine the material. CBN needs heat to cut at its fullest potential. A quick lesson: CBN generates heat in the shear zone, thus locally anealling the material, cutting it as if it were s...

| Where to use ceramic inserts and silicon nitride inserts |
| 2008-02-01 10:31:06 |
All Irons... use silicon nitride in all applications...turning, boring, milling & facing. Use for roughing, semi-roughing, semi-finishing & finishing applications. Generally speaking, silicon nitrides can be used in all iron applications. All Irons... use the black (CC-20) and/or white (CC-10) ceramic on semi-finishing & finishing applications. They are less costly and harder than silicon nitride (more abrasion resistant & longer lasting). Steels below Rc58 in hardness......
