The new DH4580 chamfer

The new DH4580 chamfer provides a cost-effective drilling and chamfering. This validated two-in-one method reduces processing time because fewer tools need to be changed. According to the company, as fewer tools are needed and can replace particularly expensive special tools, it also reduces tool costs.

Multi-purpose DH4580 is suitable for various materials including ISO materials group P, M, K, N and S, and all holes with 45 holes. In the automotive industry, this applies to cylinder head, cylinder cover and tank face, rear shell and mounting hole, turbocharger and related mounting holes. The chamfering body has six inches and a metric size, while the slot is 0.110 inches (2.8 millimeters) wide. DH4580 inverted slot valve body is suitable for all corresponding carbide bits.

The company announced the north American company’s debut in North America, and the company will launch a series of high performance solid carbide drills to further improve its extensive faucet and threaded tools. The new EF series drill is a result of a wide range of research and development, combined with special geometric structures, proprietary carbide grades and PVD coating designs, which are said to be unique to the industry. The result is three to five times faster than conventional hard alloys and cobalt drills, and high quality threads and longer tool life.

“We are pleased to introduce this important introduction to the U.S. and Canadian markets,” said Bob Hellinger, President of the company. “For the company, with a drilling and production line to supplement our leading faucet and thread production line is very meaningful, it provides our clients with their development and application of the best solution.”

In addition to starting in the fourth quarter of 2015, the company will also provide complete grinding/retuning services for all the drilling products in their west Bostown. And facilities.

The company, designed and produced in Germany, has a bilateral flute design to increase stability and round/straight holes. The unique flute structure can make the chip’s evaluation better, while the self-centering design allows drilling in one shot, eliminating the pike period and the preorder operation. The Calloy drill is a special sub-micron grade carbide class with remarkable wear resistance and durability. A unique multi-layer PVD coating is cracked and cracked and has a long tool life.

The full range of products can be used in 3XD, 5XD, and 8XD RIGS for convenience and versatility. Sku, which is above the 2000 standard, will be stocked at the company’s west boylston plant.

guide sleeve with a chip basket

MK’s design concept is to combine the guide sleeve with a chip basket so that the two items can travel uniformly. The movement of the guide sleeve is driven by the air, which helps to provide closer contact during the escape of the coolant medium. For longer deep hole drilling applications, it may be necessary to stabilize the deep hole drilling tool with a supporting liner.
The precision of deep hole drilling is greatly improved by rotating the slow part of the counterclockwise direction.
For deep hole drilling applications over 18 mm in diameter, MK can choose to equip its largest processing unit from the BTA or EJEKTOR series of drilling systems. In these applications, coolant and chip management are performed through the main axis center. The emulsion is collected at the back end of the main shaft and re-entered into the cooling system after filtration and pressure. Such solutions are often used in high-precision parts manufacturing in industries such as automobiles.
In order to process stainless steel and titanium alloys, the company introduced a new type of ex-carbon – Calloy tool drill.
The Calloy tool drill is designed specifically for problems that are common in processing stainless steel and titanium alloys, such as machining hardening, elongated chips, low thermal conductivity and welding of tools.
A notable feature of the Calloy tool drill is the newly designed super cooled coolant hole. They provide improved coolant flow to improve chip evacuation and reduce heat generation. The geometry of the flute and the sharp cutting edge produce a tightly cut chip that prevents the chip’s packaging.
In addition, the Calloy tool rig provides a stable regrind and eliminates the hardening of work in the extra manufacturing process by reducing the edge wear of its distinctive edge shape and OSG’s WXL coating.
With these features, Calloy tool’s drills are reported to show twice the length of its tool life by using more than 3,100 linear inches in the case of hard-to-process dual-body stainless steel.

BGS high carbohydrate drill

BGS tools company, said in the BGS high carbohydrate drill design key features make this product can not only in the standard carbide drill on the application of the benefits, but also can provide other high-performance bit. Every feature of BGS high carbohydrate drilling RIGS is unique design to solve common problems during high production drilling.

The stability of the two-edge design and penetration capability of point geometry allows high-carb drilling to meet demanding applications, usually requiring fewer operational parameters or two steps.

Second margin high in carbohydrates rig has polishing effect, while the flute effectively control chip, and transportation enable bit in high production environment provide superior surface coating and pore size, thereby saving the cycle time, avoided in many applications to the need of reaming.

Secondary flutes provide a cooling channel, usually not in the training of external coolant. This is a combination of tool coating and high strength edge design, which increases the operating parameters and increases the service life of the cutter.

Investment in traditional deep hole drilling RIGS can be very expensive. MK, a member of the Suhner group, now offers custom deep hole drilling solutions that can drill up to 12 millimeters of diamonds, up to 100 times the diameter. These modules can be integrated directly into transmission machines, dedicated machines or traditional machines, such as rotary machines.

MK has invested a lot of research and development time and capital resources in recent years to develop its deep hole drilling technology, according to company sources.

Now MK can provide “zhou fei” components. Thanks to the modular concept of components, MK can provide customized turnkey, small and economical deep hole drilling RIGS.

MK often tests with actual tools and materials to demonstrate the design and performance of its customized deep hole drilling solution. Test in the factory and use specific production tools in actual production conditions. MK USES a single edge cutting edge and a hard alloy spiral drill with a diameter of 70x. Using this approach, MK can stand behind the design and performance to provide practical and realistic results for customers. The deep hole drilling process usually requires a drill pipe with a diameter of 1.5 times diameter or drill bit, and then a deep hole drilling process.

length to diameter of a drill

It is well known that the greater the ratio of length to diameter of a drill is, the greater its bending tendency is. Reducing the length to diameter ratio can reduce the flexural force, thus avoiding bit breaking and increasing the aperture error. The deeper hole requires larger ratio of length to diameter of the bit. Usually, the hole depth is more than 3 times the diameter is “deep hole”, and the hole depth of micro drill usually exceeds this limit.
Generally speaking, high-speed steel drill allowed a deflection and bending force, but the corresponding, the elastic deformation ability and high speed steel has low hardness, the wear resistance is reduced, thus limiting the tool life. The hard alloy has high rigidity and high hardness, so it can make the tool life longer and the machining precision higher.
The high wear resistance of cemented carbide makes it reach 3 times the speed of high speed steel after micro drilling, and the life can also be improved. At the same time, the high rigidity of cemented carbide is helpful to correct positioning and maintain the size of the hole.
Though the tools are manufactured in the material and geometrical parameters precision drilling completed a lot of development, do not need all of the scratch test, but many factors during drilling are well controlled, is not an easy task.
So, as the diameter of the drill bit decreases and the brittleness increases, the deflection becomes the root of many problems. To control the brittleness of the drill bit, it is necessary to weigh the hardness and toughness of the tool matrix.

Choose a good LED light

Choose a good LED light, so good quality LED lights can be used for more than one year. Those who are saying that they can be used for three years, I really do n’t know what to use to ensure that, let the officials analyze it themselves

When you buy LED lights in the future, please pay attention to the above data and compare them; remember that buying a lamp is not just about whether the lighting is beautiful or not (of course, that is the most important). It is no longer just asking the boss to light up Let me show you. Please ask him to connect an electric meter when you buy a lamp, and show you all the parameters, so that it will be more secure and safe for your home.
