Grinding of the drill 1

Call Plan’s technical expert Mike Plankey made a few comments on drilling holes on the cylinder. First, the center of the workpiece can be drilled with a center drill hole, so that drilling has an accurate starting point, the other is the use of cross-grinding drill bit drill, it can make the beginning of cutting edge immediately contact with the workpiece surface , To prevent drilling misalignment.

Precision drill company senior technician Jim Geske said that at least four self-centering drill-tip types are very effective for drills drilled on cylinders: helical face grinding, Bickford grinding, four facets And cross grinding.

Bickford grinding and spiral surface grinding are somewhat similar: have a spiral drill tip, if the thin-walled tube drilling tolerance requirements of more stringent hole, then use Bickford grinding type may be better, because the hole from the first See the protruding parts of the drill tip. With these two grinding type grinding of the drill tip, the horizontal edge of the formation of a raised height, which gives it self-centering ability. However, Geske said: “Bickford grinding is not suitable for the overall carbide bit, because this grinding requires about 9 different diameter diamond wheels, the cost is too high.” At this point the tool manufacturer should consider the selection of 60 ° or 90 ° (applied to the outer edge of the drill).

The four-plane grinding is also similar to the Bickford grinding and helical surface grinding, but it has two main horns and two second horns forming four planes, which form a self- The Geske says there are two types of four-plane grinding: four-sided overlap and four sides in the center. The width of the primary side is the same as the thickness of the core. At this time the main horn determines the horizontal edge of the drill bevel, naturally the greater the rear angle, the greater the horizontal edge bevel.

Coro drill

SC has introduced coro drill bed 460- xm. The new type of drilling rig is a multi-purpose, high-performance drill, which can be widely used in various materials. The drill has high capacity utilization, flexibility and versatility. The drilling of all materials can reduce the inventory, improve the flexibility of the machine, and shorten the installation time.

The company reported that the coro rig, 460-xm, was made of fine particulate matter with a perfect combination of hardness and toughness, resulting in high abrasion resistance and longer service life. The coating has a special treatment method to reduce the friction coefficient. Strong web design provides excellent cross-section strength, plus increased flute volume, enhanced chip evacuation. The 140-degree point Angle ideal is suitable for multi-purpose drilling, with good central performance and low thrust design.

The standard diameter of the drill is 3 to 20 mm (0.118 to 0.787 inches). 2 to 5 times drill diameter (DIN 63537 K and DIN 63537 L). Achievable hole tolerances: IT8 to IT9, available internal and external coolant.

The company is now available for drilling in steel and cast iron. The coro drill 870 is part of a new generation of interchangeable tip drills designed to save time and reduce drilling costs.

Coro drill 870 can be optimized according to the possibility of diameter, step and length. Holes can be more efficient and closer to the required specifications, making them more suitable for subsequent operations.

The highly secure interface between the drill and the tip ensures reliability and precision, while a quick and simple technique change process helps to maximize machining time. The new cut geometry and grade provide a secure cutting process that allows for improved penetration while maintaining chip control and increasing tool life.

The drill has a diameter of 12 to 25.90 mm (0.472 to 1.020 inches) and is 3, 5, 8 times the length of the drill. Each drill has a unique interface size and matching technique to achieve the hole tolerance of IT9 to IT10.

Standard knowledge of Milling cutters

Since our standard platform can’t be everything to each application, and sometimes a new platform has to be created to achieve the right throughput. Below is several examples of tools which were a work in processing and some of them may become standard things in the near future based on their initial success. Please ask Informations for pricing or informations on these specific items.

Facing Grooving Tool: This tool was created to mill a specific form on top of the connecting rod for a combustion engine. The mating form was generated on the cap in order to launch a perfect mate, invoiding any shifting between the two surfaces. The form was developed by plunging in the Z-Axis down onto the part.

Stubby Tool: The 1.0″ long insert is for larger bodies and for short threads. Now With this tool we have more inserts in the cutting, with standard inserts and short, stubby tool to cut short thread forms .

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.

Adjustable Insert Face Grooving Tools: Using Advent 410 Insert, this tool is only used to plung into the workpiece in the Z-Axis. Pipe flanges are vary widely in diameter in industry, so this tool is specially designed with some compensation in mind. If you look closely, you can find that how the wedge and the insert can be moved away from the tool centerline for different part arrangements. By Using inserts with your specific form in mind, getting surfaces and gaskets to seal the first time is now available and within reach.

Combination Tools: Smaller thread forms further inside a bore, and with another thread form in the same bore or nearby.

Double Sided Insert Tools: Similar to Stubby Tools, the biggest difference is that this tool has “flippable” inserts for short threads, rather than shorter insert. These 410A class inserts have many more mass and are much more durable than the rest. Unlike our many competition, if you can chip one tooth, you really have another edge that is useable.

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:

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.
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.
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.

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 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.
