Take detailed notes on how dense and uniform the shot pattern is at each distance. Is the pattern holding together effectively enough at that range to put a dozen pellets in the kill zone, or only two or three? Do you start getting large holes in your pattern? If so, that distance is too far out for clean, ethical kills.

Determine your personal maximum effective range. Just because your buddy has excellent eyesight, depth-perception and technique and can put a dozen pellets in the kill zone at 50 yards doesn't mean you can.

It is no question that tungsten-based loads offer better performance, but know and understand your personal limits as an effective shooter.

In short, tungsten-based loads are good — very good — but they won’t make your eyesight, technique or depth perception any better — only practice on the range can do that. These loads are truly groundbreaking, and they hit harder and at longer ranges than ever before.

When tungsten carbide boring head’s cutting is in high-speed machining, high-speed rotating imbalance tungsten carbide boring head, centrifugal force and tungsten carbide boring head itself can cause large vibrations, thereby damaging the sensitive display device. The new tungsten carbide boring head by using a balancing mechanism that can reduce or eliminate unwanted vibration at high speed boring. With a digital readout screen, precision boring heads have been able to speed up 16000r/min speed boring.

New tungsten carbide boring head’s digital display shows the direct displacement of the slider of the boring tool, without having to determine the amount of displacement by adjusting the amount of rotation of the screw blade. As the boring bar boring tool mounted directly on the slider, so the number of significant readings tungsten carbide boring head can truly reflect the displacement of boring tool, and is not affected by the screw backlash errors. Digital tungsten carbide boring head this feature so that it can more quickly and precisely adjust the bore diameter, and can realize the error compensation process deviations or tool wear.

Modern tungsten carbide boring tool was able to provide greater flexibility and another factor is the manufacturer of tungsten carbide modular boring tool, like other manufacturers that have invested in better production and processing technology, in order to give full play to the modern machine processing capacity. Thus, the modular combination of a higher precision boring tool.

Tungsten carbide modular boring tool, also means that making the boring tool divided into: basic pattern (Basic Holder), extender (Extension), reducing device (Reduction), boring bar, boring head (Boring Head), insert seat (Insert Holder), a plurality of blade portions (Insert), the chamfered ring, and depending on the content of the processing (rough boring, finish boring; hole diameter, depth, shape; work-piece material, etc.) for free combination.

This way, Tungsten carbide modular boring tool can not only greatly reduces the number of tool holders, reducing the cost, can quickly respond to a variety of processing requirements and the overall extension of the tool life.

Tungsten carbide seismic boring bar is unique, and there are five main features of it. Look at the followings:

1.one piece, eliminating weld fracture problems;

2. cemented tungsten carbide boring Arbor, formulated using high toughness, tough and durable, high hardness, high rigidity, high shock resistance, ultra-deep hole boring may be imposed processing;

3. a variety of both internal water hole, when deep processing chip and the cooling effect is good;

4. straight shank structure, processing depth processing to be seeking to follow their own adjustments;

5.the body has a combination of both ends of the hole, in case of damage to one end, the other end that can be used in conjunction Arbor increase their value, more cost-effective.

Solid tungsten carbide small diameter boring tool has a large number of patterns and sizes, so you can choose the best one in actual use. Look at the following chart.
 

Take one example, D=5,I=30,Kr＝93°, the solid tungsten carbide small diameter boring tool’s pattern and size is YTD05.30-93.

Tungsten carbide boring hole is a bore machining technology widest range of applications. For large diameter boring hole almost all use the tool very easy to adjust. And a small diameter hole (hole diameter of less than 10mm), it is very inconvenient to adjust the head.

We recommend an tungsten carbide simple high stiffness micro boring tool, which is different from the traditional fine-tune the structure. Its head back and forth to adjust the spindle by relative rotation between the shank to achieve. As the head and shank is fixed coupling, so good rigidity. Arbor office is in connection with the spindle hole is processed outside, it can not be size restrictions, so its rigidity can be done well. On the spindle with cylindrical shank flange has the scale, the scale given exactly zero offset eccentric position in the spindle and arbor. Then use it to test boring first knife, then measure out the actual size (not required retraction) to adjust the amount of eccentricity can be boring arbor the desired size. The tungsten carbide simple high stiffness micro boring tool of the structure and can be as large as possible to improve the rigidity of the blade. Thus ensuring the accuracy of the hole size and geometric tolerances.

Many adjustable tungsten carbide boring tool is a fine tooth by turning the screw to adjust the boring tool machining diameter. Since the fine tooth pitch of the screw is small, when a larger size adjustment, the operator is required to rotate a plurality of turns of the screw, adjust only the low speed, and the gap is due to the presence of the thread, the readings are often inconsistent with the rotation of the screw shank actual moving amount, require multiple test cut, in order to get the correct calibration processing results.

In order to achieve tungsten carbide boring tool’s rapid adjustment, we design and manufacture of a new agency with a quick adjustment adjustable boring tool, and achieved good practical results. Arbor received clearance fit symmetrically mounted in the town of blade slots, each adjusting screw at one end and connected with arbor holes within sixty other end positioned within the regulator and with scale. Adjustable hole in the processing, first by 1/2 to adjust the diameter difference between two good regulator.

When you are rough machining cylinder bore, using DU406 tungsten carbide combination machine, this machine boring bar has 700mm length, during use, due to wear and often tungsten carbide boring tool to remove the body, dressing new cutter body, thus making threaded arbor often damaged, leading to the arbor can not be used. Since Arbor relatively heavy, frequent uninstall when workers stick, easy bruising machine.

To this end, we designed a tungsten carbide deep rugged back boring tool that adds a disk access. Lower end of the shank is processed into short Morse cone and convex milling slots, then set the upper groove milling and the cone, and Arbor docking. When removing the blade mounted on the connecting thread damage the lower disk access time, disk access as long as the new ones, tighten the screws on both sides of the disk on it, saving time and effort. Rose arbor nut is to prevent the blade will not fall short cone from the centering effect, punch trough power transmission, then the center of the plate with holes, air emissions.

After all the boring bar are transformed into tungsten carbide combination boring bar, it will achieve cost savings, and very easy to replace.

Tungsten carbide deep rugged back boring tool is a vital tool, which usually used for processing car’s two-wheel on the CNC lathe in order to ensure that the two bearing bore concentricity, often with positive bore holes and back combined method. As the wheel’s back hole deeper, limited by standard tool force, processing generate vibration, affecting the processing quality. By this we increase tool rigidity, making special tungsten carbide deep rugged back boring tool, cutting parameters to achieve high-efficiency processing, high-quality automobile wheel .
