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 […]

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, […]


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 […]

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 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. […]

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 […]

USES drills

A shop usually USES drills and cylinders to make a large diameter hole. Consider, for example, a 15-horsepower vertical machining center that USES this method to make a three-inch deep hole in a 4-inch diameter. The store takes a rotating 1.25 inch diameter drill to the first part and only takes 1.5 minutes. Next, it […]

milling cutter

The photocopier cannot replace the position of the electric drill; The surface area is too large to continue this way, beyond the required cutting depth. However, during the milling process, it is possible to produce a common processing headache during the milling process: drilling a hole before grinding. A traditional indexable vertical milling cutter requires […]

mill and inserts

If the machine has enough horsepower to enable the tool to operate at a depth of more than 1/4 inch (6.4 mm) per track, this process can be done economically. If not, the activity in this way is likely to be slow and inefficient. The button cutter provides the most aggressive selection hole creation while […]

grooves, step milling, face milling

The final shape of the workpiece plays a fundamental, but also important, role in the selection of rough tooling. Choosing the wrong cutting tool can generate additional steps in the process, reduce profitability, and negatively impact delivery. For grooves, step milling, face milling to the shoulders, and most 2-d milling, the shoulder tools are the […]
