The application information recommended by cutters for rhino feed

Application information

The application information recommended by cutters for rhino feed

Tools are best suited for “z-level” roughening; Reach the cutting depth (DOC) and remove the entire plane.

The use of rhino feed is not recommended. Increase (2 ˚ Max.) Recommend it.

The use of a rhino feed tool absolutely requires climbing. In the conventional milling process, the damage of the cutter or part may occur.

Keep at least 75% cutter diameter on the workpiece as much as possible. Hang the tool on the side of the work, and the service life and performance of the tool are unfavorable.

In a possible case, the cutting width (WOC) should be 60-75% of the diameter of the knife. The slight scallop effect is acceptable. For longer tools, this is particularly important – cutting pressure should be on both sides of the center line.

High feed milling produces a thick slice that can effectively take away heat. Combine it with a slightly lower SFM to get very good tool life.

Use the feed rate compensation chart on each insert page to compensate for thin slices that appear in the rhino feed socket. This will provide the best metal removal rate and tool life.

Technical factors

Use the anti-robbery compound regularly on screws.

Insert screws for every 10 inserts.

Use short length knife rack (end milling cutter) to achieve maximum hardness; The cutting tool shank shall be as upward as possible in the spindle cone of the machine.

Thoroughly clean the pocket and screw each insert replacement.

Use a tool holder for rough handling: use end mills and power clamps; There is a seam jacket not recommended.

Tighten the screws before clamping the screws.


Modern metal cutting techniques may use very high operating parameters (speed, feed, cutting depth, etc.). This creates the possibility of flight chips and debris, and can cause tools to break down for a variety of reasons.

Operation instructions for small feed inserts

Operation instructions for small feed inserts

The operation of small feed insert inserts has the smallest IC (inner circle) and the smallest cross section. These inserts are recommended to run good feed and DOC combinations. Higher feed ranges can be accepted when running a light DOC. When running a heavier DOC, use a lower middle feed range. Insert an index into a prominent garment to avoid breakage.

The operation instructions of the feed interpolation insert are more cross-section than small feed, but smaller than large feed. These are good universal insert tools that are best suited for the lightest (40 degrees, linear, etc.) machines. In most cases, run faster feeds with lighter documents. In the heavier DOC, run the feed range in the middle region.

The drill is drilled with a indexable drill

Consider the following. The EHWT has a 5.5-inch diameter hole, mounted on a plate about 4 inches thick, and runs at a 15-horsepower vertical machining center with 40 conical shafts. The machine can reach 1.125 diameter indexable drill without stopping. As EHWT sees, it has four options:

The drill is drilled with a indexable drill, and then the circular interpolation is carried out with the indexable end milling cutter. This process will be difficult because of the length of the tool required and the radial cutting force involved. Significant deviations are inevitable. In order to avoid severe flutter and hole size too small, it must be cut with the end milling cutter. The approximate period is 60 to 90 minutes.

Drill into a relocable rig and then use multiple boring rods to increase one diameter at a time. This process will produce a straight and accurate hole, but it will take time. It will also be expensive and will make it more difficult to evacuate the chips. The approximate period is 45 to 60 minutes.

Heavy round interpolation with spiral milling cutter. This method will consume a lot of horsepower and will probably not cause damage to the size of the machine.

Screw interpolation – with or without initial drilling. For this application, a 3-inch diameter indexable milling cutter works well from the start. Drilling before drilling will help to evacuate the chips, but this is not a necessary condition for success. Depending on the style of the tool used, it takes about 65 or 200 times to break through this section. While this may sound like a lot of cutting, the actual cycle time is relatively short. The approximate period is 10 to 22 minutes. Using Felix, this process can be executed with a cutting tool and runs within 5 to 10 minutes of a cycle.

Operating instruction

end mill for stainless steel


The EHWT merger (Rockford,IL) has greatly improved its hole making ability by using helical interpolation technique. This concept was introduced to them by the DPA company (Bloomfield,CT) in order to improve the cycle of the new part. Don Busekros, owner of EHWT, explained: “we have an application that can produce new production lines based on A2 tool steel. These bases require a large amount of metal removal, including a 3-1-1 inch diameter hole through a 2-1/2 inch thick part. Our initial idea was to drill a hole about 1 inch in diameter, then insert the rest of the circle with a 1-inch end mill. Let’s say that our machine cuts at $0.200 per track, and what we see is a cycle of 15 to 20 minutes per hole. Using spiral method to shorten our cycle time to more than 5 minutes per hole is much easier on my machine tool.

EHWT takes the ball from the big hole to just a few minutes. These gains are the standard 90-degree milling cutter using the DPA, which operates on high surface steps and slight slope angles (less than 1 degree). EHWT found that it can save 50% or better cycles by moving away from traditional milling techniques and using spirals.

The company USES a 90-degree tool because it is a tool already used for other work. However, there are different cutting tools for this kind of processing. DPA has introduced a new product designed specifically for this type of milling. Felix is a modular system that can be designed to be five times the diameter of a diameter, which can be inserted into a hole in a third of the time of a standard milling cutter. “For this type of milling cutter, a square shoulder mill is an acceptable option because it is usually used for other applications,” explains Mike Bitner, DPA’s regional application manager. A shop that doesn’t use this kind of milling often can also use it. However, a shop that regularly applies for this type of milling cutter will be better able to invest in tools that can take a more active approach.

end mill for stainless steel

cutting using a rounded insert.

With the right tools, even a 10 or 15 horsepower machine can make competitive metal disassembly, thus reducing the installation and greater flexibility of the workshop.

Closer to completion

A semi – completed or completed cut provides new possibilities for semi-finished or completed cutting using a rounded insert. When using a 90-degree tool for roughing it, each step (or at each of the z-grade roughness) leaves a “step”. The heavier the depth of each cut, the more obvious the ladder effect. The resulting uneven surface will result in uneven pressure of the semi-finished product. This impact tool also causes a shift of deflection, making direct progress from rough to end. Not only do you need a semi-finished product, but you need to do it multiple times.

Using round insertion greatly reduces this effect. On the steps of the 90-degree tool, there are smaller “scallops”, which are lower and easier to pass. This effect is complementary, because circular insertion is optimal in a lighter cut depth, because the lighter depth makes the fan less noticeable. The remaining remainder is more evenly distributed after the roughness, and in some cases can be done without a semi – finished product.

The production of large diameter holes is a common application in many stores, and there are many ways to achieve the ultimate effect. However, there are usually many obstacles to effectively completing this process. In these types of applications, the power consumption is often a problem, especially in the more common 20 horsepower and the following machine tools. These machines have a high speed and speed, but in order to achieve rapid motion, rigidity is sacrificed. Using traditional methods, making large diameter holes is difficult for machine tools and tools. This fact creates a smoother way to keep the holes in the necessary cycles to stay competitive.


It should be noted that some button cutter users have problems inserting motions in the pocket of the cutting tool, or when the insertion is worn down. In both cases, the tool pressure increases and the insertion clamping effectiveness is affected. The cutter should include design features that enhance the tool integrity of these applications. For example, some cutters use spiral inserts with extra top clamps. These knives provide a dual clamping security for each insert.

Another important feature is the locking of the insertion location. Many button cutters use cheap die casting inserts, rounded edges, and do not provide radial locking for insertion. Cutting to the cutting force on such an insert may cause the insertion screw to lose torque. A more rigorous copying machine solves this problem, with the inserted side of the surface locked on the surface, with matching units on the knife body pairing, almost no chance to move.

Finally, look for tools that provide the most support, especially if the high feed rate is the target. Using negative axial rake (will insert tip down onto the workpiece) of copying milling cutter can make good use of the parameters of the conservative, but more aggressive in metal cutting process was not able to make good use of. Inherent in design is the lack of support for the force, which is at the top of the line. (see figure 2). The copying milling cutter with a positive axis rake provides a better cutting edge support because the hard alloy at the back of the cutting blade is closer to cutting. Positioning the carbide in this way allows the end user to absorb the high compression force using the carbide’s ability.

But in this case, it’s important to keep the tool stiffness. The holder of the long tail milling cutter or the holder of the shell mill is highly recommended.

Low – horsepower metal cutting

Without any corners, round insertion provides the strongest cutting edges available in indexable carbide blades. Strength comes in handy when you’re operating on a very heavy cut, or if you try a rough cut under unstable conditions. When using long tool cutting, circular insertion makes it easier to deflect and flutter, increasing speed and feed rate, reducing the risk of insertion.

The cuts are also more effective. A typical 90-degree cutting tool, most of the tool pressure is radial, causing high deflection and increased likelihood of vibration or breakage. The circular cutting edge spreads the force more evenly, and the greater proportion of the tool pressure guide axial direction. This is also desirable when using a longer length tool, since reduced radial pressure reduces deflection.

But pay attention to this when you use a horizontal machining center. An increase in axial pressure may result in the bending of the workpiece, usually on a pedestal or corner plate, rather than as a solid base for a vertical machining center. On the HMC, this bending can cause microchips to be inserted into the tiny vibration of flex. Cutting tool life and cutting tool breakage are more likely. To reduce or eliminate this problem, you can try a positive axial rake cutter, which minimizes the downward thrust to the workpiece.

Low – horsepower metal cutting

In the right way, round inserts can produce impressive material removal rates without an impressive horsepower. The strength of the round insertion can make it impossible to use the 90 degree cutting tool speed, even the lightest machine can be violently roughened. The key point to understand with circular insertion is that a heavier cutting depth leads to higher chip thickness, which increases the power consumption. (see figure 1). Through light cutting – 0.025 to 0.50 inches deep cutting – a typical circular cutting tools can be at a rate of around 0.040 inches per tooth to provide feed, in some cases, each teeth up to 0.060 inches. In contrast, most of the parallelogram or square inserts limit in 0.010 to 0.012 ipt.
