Air Turbine Tools offers its Tool Breakage Alarm System to protect work in process and cutting tools, which helps prevent scrapped parts, lost hours and machine damage.
As cutting tools follows the programed tool path, Air Turbine Tools’ tool breakage detector system monitors air flow for deviation from a sensitive baseline record of compressed air consumption.
If the cutting tool breaks, Carbide Inserts the Tool Breakage Alarm System activates to alert the operator with a light and/or a klaxon. Operators can also program the system to stop the CNC machine automatically if the CNC or robot control Tungsten Steel Inserts is connected to the Tool Breakage Alarm System’s external port — permitting unattended operation 24/7.
Compressor malfunctions are also detected by the system. If a compressor malfunctions, or if air flow is diverted to other machines, Air Turbine Tools’ Tool Breakage Alarm detects airflow cavitation and alerts the operator or stops the program, protecting work in process, tools and machines from drops in air pressure.

The photo shows two combinations of tool and toolholder that are used in the same machine. Which of these tool sets will permit heavier cutting? The shorter, more rigid one? Maybe not!
The actual answer depends on the Cutting Tool Carbide Inserts machine. At higher spindle speeds, the heaviest depths of cut are possible near the natural frequencies of the machining system—and that system includes the machine, toolholder and tool. Sometimes, less rigid tools contribute to a dynamic system capable of a higher metal removal rate.
Warner Robins Air Force Base discovered this very thing. The base’s machine shop is "tap testing” all of its high speed machining centers to find their optimal machining parameters for every standard tool set. On one of the shop’s machines, more aggressive milling is possible with the longer of the two tools seen here. This article explains.
The phenomenon has an interesting application. It is actually possible to "tune” your productivity by adjusting the tool overhang length.
Question: DNMG Insert Has your shop had experience with finding and applying harmonic frequencies in high speed machining? What kind of results have you seen? E-mail your reply.

Coolant Ring Technology (CRT) holders from Scientific Cutting Tools are made from high quality heat treated steel and come with a black oxide coating. They are engineered to allow for better coolant penetration deep into the bore, reducing temperature at the cutting edge, the company says. The overhang of the tools used with the holders is infinitely adjustable CNMG Insert rather than fixed, allowing for maximum performance without chatter or other performance-related issues.
The CRT holders can be used in conjunction with the company’s qualified boring bars and/or qualified threading tools for quick change machining at optimal performance Carbide Milling inserts levels, according to the company. Qualified boring bars have an overall length that is qualified to ± 0.001” and a minimum bore diameter that is qualified to ± 0.0005”. They can be used in conjunction with the CRT holders for quick-change setups or with our QHC holders when a backstop is used (sold separately). The CRT holders used in conjunction with the qualified boring bars have the advantage of more effectively delivering coolant to the cutting edge.

Personnel from Boeing's Research & Technology group recently answered readers' questions. Carbide Inserts One reader asked the following.
Question
I am roughing Al 7000-series material at around 30,000 rpm using a 1-inch solid carbide uncoated end mill with 2 flutes at an axial DOC of 0.200 inch and a radial DOC of 50%. I am using an HSK80 toolholder, coolant through, with a good machine and stable setup.
At this speed, there is no surface finish difference if I climb or conventional mill. But is there a difference between the two methods in terms of tool life?
Response from Boeing’s Research & Technology group
With 7000-series aluminum on our own 24,000-rpm Indexable Carbide Inserts spindle, we achieve 200+ hours of tool life using carbide cutters. We do both climb and conventional milling and we do not see tool life being affected. For us, the key to long tool life and good part finishes is dynamically testing all of our cutting tools first before high speed machining aluminum. By doing so, we find what is called the "sweet spot," which is the optimal rpm and depth of cut the cutting tool will run with no chatter regardless of step-over, full slot cutting or corners. Once we have these parameters, we program to them—confident that we will not have any cutting tool chatter issues. The system we use for this dynamic testing is called "Metal Max” from Manufacturing Laboratories, Inc.

I was perusing Twitter the other day when this Coated Inserts YouTube video caught my eye. Although I have often appreciated the fascinating Discovery Channel show "How it’s Made” for bringing metalcutting into the living rooms of the general public every once in a while, I wasn’t aware that an episode had been dedicated to the manufacture of industrial cutting tools. I Carbide Milling Insert think it’s well worth a look. For one, it’s pretty neat. Beyond that, it serves as a reminder of how many layers there are to manufacturing. That is, tools are made by tools, and the time and effort involved in using any variety of production equipment effectively may well be equivalent to what was required to manufacture it in the first place.
Although the video focuses on solid tools, I find the various processes employed to manufacture carbide inserts just as interesting. In fact, watching this reminded me of a visit to Germany three years ago, where I got a first-hand look at P.H. Horn’s insert manufacturing process. Here’s a virtual tour of that operation as it looked then.
Finally, feel free to connect with me on Twitter, where I discovered this video in the first place: @MMS_MattDanford.

WorkNC G3 automatically generates optimized roughing and finishing tool paths for two- through five-axis machining applications. The new NCSpeed module, developed by Formtec and fully integrated into WorkNC, can produce additional cycle time reductions.
NCSpeed uses a computer-generated stock model that is updated dynamically and continuously. This more advanced method allows the module to calculate the load and thus forces generated on the cutting tool. The module will then increase the feed rates during conditions EPNW Milling Insert of a lighter cutting load. Conversely, for cutter safety, NCSpeed can lower feed rates where appropriate, such as during areas of high cutter loads.
By keeping tool loads as constant as possible, the module allows engineers to achieve the best possible cutting conditions across the whole job, having a positive impact on accuracy and the quality of the surface finish, the company says. By avoiding excessive load conditions and by keeping the volume of the material consistent, cutter deflection will be minimized, tool life will be increased, excessive SOMT Insert vibration and chatter will be eliminated and cutter breakage will be avoided.
The software also checks for tool engagement with the material, maximizing movements at rapid feed where the cutter is out of the material. It also shortens the overall length of rapid tool paths where it is safe to do so.

China molybdenum price was stable in the week ended on Friday March 19, 2021 owing to weak market demand and low prices of steel tenders. Most insiders remain low buying appetite with low trading concluded in the market.
In the molybdenum concentrate market, the price of raw materials was firm due to the support of limited raw material inventories; the ferro-molybdenum market was under pressure. Although steel mills were active in restocking, ferro molybdenum sellers tungsten carbide sheet kept cautious because of low tender prices and high raw material prices. As for the molybdenum chemical and its products market, on-site transactions were not very high, and the demand from end customers was weak. In order to avoid the problem of price inversion, holders have a strong sense of reluctance to sell.
In the news: In February, steel prices in the domestic market turned from falling to rising, according to the monitoring of the Iron and Steel Association, at the end of February, the China Steel Price Index (CSPI) was 131.36 points, a month-on-month rise from a decline, an increase of 8.33 points from the end of January, an increase of 6.77%; a year-on-year increase of 30.97 points, an increase of 30.85%.

Selecting the correct tapered leader and tippet for the type of fishing you are about to do is crucial. Nothing can spook fish quicker than an oversized tippet for the particular situation. On the other hand, and undersized tippet can result in the fly fisher losing their trophy before they even get a photo opportunity. We will start at the very basic of leader and tippet selection and then get more specific, and hopefully conclude with enough information so we?ll always have the proper leader and tippet for all upcoming fishing scenarios.
What is leader and tippet
Leader and tippet is the final connection between the fly fisher and their fly. It is the section of line after the fly line and before the fly. It?s purpose is to transfer energy from the fly line down to the fly, allow for natural presentation of the fly, and then be strong enough for the fly fisher to retrieve any fish that might strike at the naturally presented fly. Sounds simple enough, but this is fly fishing, and fly fishers have been around a long time. And as a group we seem to think about everything related to our sport a lot, and therefore probably have over complicated things a tad.
The leader in fly fishing is tapered. It is thicker at the butt section, then at the tippet section. It is usually divided into three sections, the butt is tied directly to the fly line, and is the longest portion of the leader, about 60%. The mid-section is next and its purpose is to taper down to the tippet without losing a lot of strength. The final section is the tippet, it is the actual section that is tied to the fly. It is the thinnest section, it needs to be strong, yet allow for a natural drift, without alarming the fish that your offering is connected to a person that will pull back.
Commercial leaders by and large achieve all this in one smooth product. Although there are still knotted leaders out there, by and large knotless leaders are the choice. It is possible to construct you own leaders and many people do. But that is the topic of another article. A fly fisher does, however need to know how to attach new tippet portion to the fly line, I prefer the double surgeon?s knot, but the blood knot is also popular. Learn how to tie these knots before fighting that monster! A poorly tied knot will reveal itself at the most opportune times.
X factor
Now comes the fun part. A new set of numbers to learn. Different numbers then choosing flies or fly rods. Fly fishing is overwrought with numbering systems, and unfortunately leaders and tippets you are just going to need to learn. They are sized on the X numbering system. So when you hear someone say they are switching to a 6X, you now know they are talking about their tippet. X measures the diameter of the leader minus .011. So a 6X would measure .005. A 0X would actually measure drop shot weights .011. One really only needs to remember the HIGER the X, the smaller the diameter. The other number worth noting the test, or breaking factor, a 4lb test leader will break when more than 4lbs pressure are applied. This is worth noting, and many a trophy are lost when violating that #.
There are many variable to consider when selecting the right X, but the two most common are the size of fish you are going after, and the size of fly you are using when going after them. A quick guide is as follows:
XFly
0 2-6
1 4-8
2 4-10
3 6-12
4 6-14
5 12-16
6 16-20
7 20-24
8 24 and smaller
Length
One must also think about the length of the leader itself. Leaders are sold these days anywhere from 4 feet to 15 feet. There are many things to consider when deciding on length, some are variable like wind and water clarity. Other variable are static like size of fish, current, etc.
Typically the easier it is to spook a fish, the longer the leader you will need to use. So
The industry seems to have setthttp://leandercle.blogtez.com/post14.php

Deep-sea fishing is fishing that involves trolling deep waters with large fishing tackle. Compared to other types of fishing, deep-sea fishing requires more fishing equipment including more line, rods and lures. Rods, reels, bait and tackles are the fishing equipment generally required for deep-sea fishing, and specialized fishing boats are needed for angling.
Basically, there are two types of deep sea fishing techniques - trolling and bottom fishing. The fishing technique is chosen, based on the location of the fish. Trolling techniques require keeping the fishing boat at a constant speed of six knots. The bait used is usually a fishing lure that is drawn on a line through the water slightly below the surface of the water. In bottom fishing, the boat anchors in deep water and hooks charged with lures are dropped to the bottom of the sea.
Seining, long lining and netting are some other techniques used in deep-sea fishing. Seining is an angling technique used in areas where there are large schools or groups of fish. As the name implies, long-lining gets its name from the length of the lines that are used. It is one of the popular methods of fishing used to attract fish. The bait is strung out on a long line held up by buoys. Netting techniques rely on nets that are set in shallow water around the coasts.
Wholesale BASS FISHING The Mississippi Gulf coast, San Diego coast, Cozumel coast and Cancun beaches are among the most popular destinations for deep-sea fishing. Even though deep-sea fishing is specifically for an experienced angler, it is one type of sports fishing that anyone can enjoy.

Molybdenum market quotation in China: molybdenum concentrate price is about 1,740.00 yuan/ton, ferro molybdenum price is 118,000 yuan/ton and moly oxide price is 1,840.00 yuan/ton.
Under the situation that the international molybdenum price is adjusted sideways and the new round of tendering activities for steel mills has not yet begun, molybdenum chemical companies are relatively weak in raising prices, and supported by production costs, the willingness to sell at lower prices is also low. Therefore, new orders are limited. Insiders Tungsten Carbide Round Rod expressed that the market may continue to be in a stalemate in the short term.
In the news: In late February, the social inventory of five major steel products in 20 cities was 16.95 million tons, an increase of 2.16 million tons (14.6%) from the previous month; an increase of 7.22 million tons (74.2%) from the end of January; an increase of 9.65 million tons (132.2%) from the beginning of the year; a decrease of 2.1 million tons (11.0%) from the same period last year.
