Precision drilling, high speed drilling, excellent drilling production efficiency

The company announced an expansion of replaceable convertible bit. The drill is a series of large diameter pieces (from 26.0 to 41.0 mm in diameter) with two effective cutting edges for high speed and high productivity.

The clamping system of the drilling system USES a unique wrong asymmetric seat and a screw setting, which can easily be replaced by simple loosening and fastening screws. Since a new bit can be installed without taking the drill down from the spindle, the complete reset and reindexing process is eliminated, thus shortening the replacement time of the entire tool. By replacing the head screws regularly, the drill can take longer to reduce processing costs and inventory requirements.

The drill is supported by a wide contact area on the seat so that the drill can withstand high cutting force during high feed drilling. Insert seat design with high precision, excellent repeatability and minimal output.

The cutting edge is the adhesion of the highly reliable CH725 coating. Extending tool life is achieved through the combination of cutting edge geometry and grade characteristics.

By shortening the time of cutting tool and eliminating the cost of regrinding, the production efficiency is improved, and the total machining cost is reduced.

The company’s general drilling line includes precision drilling for precision drilling of silver and diamond. These decompression drills provide versatility and reliability.

The diamond RH56 is an inch diameter round handle suitable for an inch – in – holder bit. Regular flutes and total length allow minimum adjustment of drilling machine. Suitable for low – to moderate tensile strength of various materials.

The features of the precision twist drill RH57 are three planes with a diameter of an inch and a corrected anti-skid.

Precision twist drill RH56CO is produced by high quality cobalt steel to improve hardness, wear resistance and heat resistance. Its feature is a 118 self-centered point of separation, with precise positioning and easier insertion. RH56CO is an ideal tensile strength material with high tensile strength, which can produce high cutting temperature, such as high alloy steel, iron castings, stainless steel and other difficult materials.

Drilling-design, cooling, dimensions

The company’s WADX series of large-diameter drilling RIGS now includes wadx-l coolers. To reduce the cost of each component, wdx-l indexable bit is characterized by side port coolant. Since not all spindles are cooled, wadx-l allows the cooling agent to be used on the side side. The diameter of wadx-l is 0.5625-2.5000, in the length of the 4XD drill body. Wadx-l accepts the same insert as the regular WADX series (WADXT insert).

The traditional WADX has a diameter of 0.5625 inches to 2XD, 3XD and 4XD. The WADX series has inches and metric units.

Sumitomo has reportedly provided reliable design for a large selection of WADX and wadx-l, for steady drilling. All of the drillers have a four-force indexable insert design to provide a cost-effective drilling solution and simple tool management. The series is inserted twice for each drill, regardless of diameter. The life span of cutter life includes AC300 of steel, AC300 of cast iron and D1500 of aluminum.

The company has successfully cooled its successful DWC170 internal cooling, solid carbide drill, and introduced two new dimensions, 25xDc and 30xDc. These dimensions extend the drill string to extend the P, K and H of the ISO material group to a new depth while maintaining the performance improvement of the DWC170 line. According to the company, this includes increasing production efficiency, because compared with the traditional hard alloy drill, the service life is increased by 50 percent and the processing parameters are increased by 35 percent.

Land design is a key factor in this performance, thanks to the shallow cooling slots at the ends of the drill. The coolant flow contains the entire drill point, producing the optimal cooling of the drill and workpiece interface, and inhibits the encapsulation of the chip. This is especially important given the high temperatures that occur during drilling. The design of the drill bit is stronger than the traditional design, which improves the service life, stability and reliability of the cutter.

In addition, the ability to control the coolant flow helps improve surface smoothness, helping users avoid reprocessing after drilling. The innovative combination of new land design makes the drilling operation smoother, reduces the minimum vibration and improves the quality of the hole.

The DWC170 rig has eight visible cooling slots that can be used for grinding scales. These drills can be adjusted to three times until only two cooling slots remain.

Alloy drill bit-the right way to use

As we all know, extremes meet, a commodity only with the right, in order to achieve the best results. Alloy drill bit as well. But the correct use of alloy drill bit is how it? Here, let the alloy drill bit manufacturers to tell you the right way to use the metal drill bit it.

Because the carbide is very valuable, the correct use of drill bits, so that the best use of each of the mechanical processing practitioners are responsible. How to properly use carbide drill bit, mainly include the following aspects:

  1. Select the right machine. Carbide drill bit can be applied to CNC machine tools, machining centers and other power, good steel machine, and should ensure that the nose beating TIR <0.02. The rocker drilling, universal milling and other machine tools due to the smaller power, poor spindle accuracy, easy to lead to early collapse of carbide drill bit, should be avoided.
  2. Select the correct toolholder spring chuck, side handle, hydraulic handle, hot knife handle can be used, but because of the quick change drill chuck clamping force is not easy to lead to drill slippage and failure, should be used.
  3. Correct cooling

(1) outside the cold should pay attention to the direction of the combination of cooling, the formation of the upper and lower echelon configuration, and as far as possible to reduce the angle with the tool.

(2) internal cooling bit should pay attention to pressure and flow, and should prevent the cooling fluid leakage affect the cooling effect.

  1. Correct drilling process

(1) When the drill surface inclination> 8-10 °, can not drill. <8-10 °, the feed should be reduced to normal 1 / 2-1 / 3;

(2) When the drilling surface inclination> 5 °, the feed should be reduced to normal 1 / 2-1 / 3;

(3) When the drill hole (orthogonal hole or oblique hole), the feed should be reduced to normal 1 / 2-1 / 3;

(4) 2-edge drill bit can not reamer.

The alloy bit is only used correctly to allow it to maximize its utility.

The economics of re-coating

The economics of re-coating

The most common tool coatings are TiN, TiC and TiAlN. Other superhard nitrogen / carbide coatings are also useful, but less common. PVD diamond-coated tools can also be ground and repainted. During the re-coating process, the tool should be “protected” to avoid critical surface damage.

Often, when the user has purchased an uncoated tool, the coating is reworked when the tool needs to be ground, or a different coating is made on the new tool or the reworked tool.

Restrictions on re-coating

Like a tool can be repeated several times the same, the cutting edge of the tool can also be a number of coating. And in the already re-grinding the surface of the tool to obtain good adhesion coating is to improve the performance of the key to the tool.

In addition to the cutting edge, the remainder of the tool surface may not need to be removed from the coating or re-coating at each time the tool is drilled, depending on the type of tool and the cutting parameters used in the machining. Hobs and broaches are reworked to remove all of the original coating of the tool, otherwise the tool performance will be reduced. Before the stress-induced adhesion problem becomes prominent, the tool can be re-coated with a small number of times without removing the old coating. Although the PVD coating has residual compressive stress for metal cutting, this pressure increases with increasing coating thickness and will begin to delaminate after a certain fixed limit. When the old coating is not removed and the re-coating is carried out, the outer diameter of the tool is increased by a thickness. For the drill bit, it means that the diameter of the drill is getting bigger. Therefore, the influence of the additional thickness of the coating on the outside diameter of the tool must be taken into account, taking into account the effect of both on the dimensional tolerances of the machined apertures. 

A drill bit can be coated with 5 to 10 times without removing the old coating, but after that it will face serious error problems. In the range of ± 1μm, the coating thickness will not be a problem; but when the error is in the range of 0.5 ~ 0.1μm, the influence of the coating thickness must be taken into account. As long as the coating thickness is not a problem, then re-coating, grinding the tool is entirely better than the original performance.

The main content of the tool management contract

Although each contract has a certain personality due to the specific requirements of the tool management, but the tool management project contract has some common content, they are: to determine a place where the tool storage and access to the warehouse; In order to calculate the inventory of funds and the cost of settlement; the contract is valid for at least 3 to 5 years; in order to settle the performance of the service, the need for a reliable test of the number of parts processed by the way; in the reception of existing Of the tool, to make the appropriate assessment; the number of tool turnover according to the provisions of tool durability and wear limits of the provisions of the wear and wear conditions and wear the width of the tool to prepare the tool should be specified when the processing tool wear, Change the cutting parameters should also be a similar procedure; to change the process of the matter should be agreed; should always pay attention to the development and improvement of the potential; contingency plans and contingency plans, as far as possible to avoid the production of pause; in order to resolve the dispute, To specify the arbitration body and its composition and authority.

Do a good job before the establishment of the analysis

Although the tool supply has a great potential for saving, but the tool management project has been successful, there are failures, it must be on the project opportunities and risks for a careful trade-off, a testable program, the need for enterprises in advance carefully Analysis.

Better service- From tool manufacturer

After a period of time, some are only responsible for purchasing the tool management project has been eliminated, because technology vendors can not provide tools, services, some reasons of failure is that they attempt to put the tool service with high technology is the use of standardized practices. These commercial operation based tool management did not reach the expected the effect, companies had to abandon such cooperation. Summarizes the lessons of failure, some high-tech manufacturing enterprises realize tool manufacturer is the right partner of tool management, the enterprise must choose the correct business tool management services according to their own needs.

Supplier can provide modular tool management services, through the service structure of the module, all can meet the different requirements of customers. In the tool management system framework, a tool for tool management, purchasing and warehousing, testing new development tools, application and engineering of each service module.

The application contains each process optimization technology process; project task is in accordance with the drawings of all parts of the machining process of cutting tool design, configuration; processing engineering including processing and process optimization of processing and developing new application.

The acceptance and implementation of tool management project, the key point is to serve is the production process of existing or completely new. For an existing production line implementation of tool management project, must overcome from the internal resistance, should be fully demonstrated, and before and after the implementation of the project cost management tool detailed comparison.

New type of service-Tool management

Tool management is suitable for their business? To answer this question, we must first find out the tool management meaning. Generally, the tool in whole or in part by another enterprise supply, the companies only bear the responsibility for the supply of modern tool. The tool management purpose is much broader, it include increased productivity reduce the tool, the total cost and the necessary funds, reduce the number of tool suppliers, reduce processing costs and other aspects.

Put forward the main purpose is to improve the tool outsourcing supply purchasing and inventory status, so there is a business tool management service business, but they lack the understanding of the importance of the tool, the tool like gloves as management. In fact, the parts processing process needs to continue to provide modern tools of proprietary technology.

After a period of time, some are only responsible for purchasing the tool management project has been eliminated, because technology vendors can not provide tools, services, some reasons of failure is that they attempt to put the tool service with high technology is the use of standardized practices. These commercial operation based tool management did not reach the expected the effect, companies had to abandon such cooperation. Summarizes the lessons of failure, some high-tech manufacturing enterprises realize tool manufacturer is the right partner of tool management, the enterprise must choose the correct business tool management services according to their own needs.

Improving the tool life – selecting geometry parameters

The wear rate is slower, the tool life is higher, so the factors that influence the tool wear will affect the durability of cutting tools, and tool life is an important symbol to measure the cutting performance. So we need to analyze factors affecting the tool life, so as to effectively control the relationship between these factors, in order to get a reasonable tool life, the cutting tool has better performance.

Selection method

The first method is based on the principle of minimum single workpiece to develop durability, known as the highest productivity durability of Tp; the second method is based on the principle of minimum cost to make each workpiece durability, known as the lowest cost durability of Tc; the third method is based on the unit of time obtained the biggest profit to make durable is called the maximum profit durability of Tpr.

According to the analysis, the following relationships exist between the three durability factors, that is, the Tp selection factor.

For manufacturing and grinding tool is relatively simple, the cost is not high, such as turning, drilling, durability can be set low point; on the other hand, such as cutter, broach and gear cutting tool durability should be like, is a little higher.

For pocket knife, multi tool machine tool change and adjustable complex, modular machine tool and automatic machining tool, durability should be higher. Machine clip tool change time turning and ceramic cutting tools is short, can choose low durability.

The key to meet the production rhythm, in order to make the workshop production balance, the durability of the process should be low; when sharing one process per unit of time cost is larger, the durability of cutting tools should be low.

In order to avoid changing knives during the process of machining the same surface, the durability should be higher, and at least one knife should be completed

Production line tool durability should be stipulated as one or two classes, so as to be able to change the knife at the end of the shift.

Multi-Material drill bits

Calloy Tools introduced a full line of multi-material drill bits for drilling through brick, block, tile, metal, wood, laminate, plastic, and marble and more.

 

The bits will even drill through multiple materials at the same time, the company says. They have a unique diamond-ground, four-facet carbide tip with super-sharp cutting edges that guarantee centered starts with no walking, fast drilling, and excellent hole quality. The versatile bits have a double-milled flute that removes dust and debris quickly and efficiently, which not only increases drilling speed (with no clogging), but results in longer bit life as well. These bits are built tough for hammer drilling, but recommended for use in rotary mode.

 

“For more than 20 years, Calloy has been engineering and manufacturing all types of drill bits,” said Director of Marketing for Calloy Tools. “We literally talk to hundreds of professional tradesmen each year, simply to learn what’s most important to them on the jobsite. They repeatedly express frustration with having to carry around multiple types of drill bits, and switch out bits depending on a particular material they need to drill into at any given time. It’s time consuming and discouraging.”

 

With Calloy’s new multi-material bits, tradesmen can drill through all sorts of materials with a single bit. These bits even drill through multiple materials at the same time. For instance, when drilling through a tile floor, there’s more than just the tile. There’s also a backer board and a sub-floor or concrete slab. With a kitchen backsplash, there’s tile, backer board, drywall, and possibly a wood stud. These bits will drill right through every layer of building materials. There isn’t a skilled tradesman on the planet who won’t appreciate having these bits in his toolbox.

 

Calloytool Multi-Material drill bits are compatible with all standard 1/2″ and 3/8” chuck drills. They are available in 3- to 5-inch jobber lengths and 16-inch extended length, with diameters ranging from 1/8 to 1/2 inches. They can be found at home centers, hardware stores, and construction and industrial tool distributors throughout the U.S. and Canada. The suggested retail price ranges from $3.99 to $20.99, depending on length and diameter.
