Executable multi-purpose tool for a variety of cutting tasks

In the past, the tool used to cut grooves that can only process a groove or cut off parts. However, under appropriate conditions, the improvement of the tool design, materials and coatings can make it multi-functional tool that can perform a variety of cutting tasks.

Most of the turning operation processing, often require programmers and engineers to take into account things outside this range. Among them, one thing to consider is how will each tool into a multi-functional tool. For example, you can drill to drill the center and positioning changed the chamfering tool; also some thread cutter end mill into a good groove cutting tool cutting function In addition to the machining grooves. Obviously, the cutting of the groove cutting tool groove is the most ideal, but from savings potential of debugging time and processing cycle to consider, these cutting tools used in other processing operations would be very worthwhile.

A distinct advantage

Grooves are mainly three types of outside diameter of the groove, the inner diameter of the groove and groove, to understand this is very important. The main design tool for cutting outer diameter groove is the maximum stride length of the tool in the processing of these three types of tool, two-way, major efforts on the workpiece machining. Design its groove Groove-N-Turn turning tool series is located in Fort Wayne, Indiana State grooving tool manufacturer ThinBit take into account this problem, the other tool manufacturers also provides a tool with similar functionality. All of these tool designed to allow users from the surface and the outer diameter of the parts processing, and then transformed into the groove processing, thus shortening the processing cycle of the parts. In the workshop of processing a variety of short-term series of parts of products, due to the geometry of such parts with groove grooving knife as a multi-function cutting tool, either shorten the debugging time of the tool can also reduce the CAM software the number of knives in the library. Another advantage of this approach can reduce the inventory of carbide inserts in the tool library. Only need to purchase a small amount of groove blade can adapt to the ever-increasing workload for the smaller workshop may be seen from the decrease in the number of some of its advantages.

Even if the trench has sufficient width, but with the grooving knife obviously has more advantages than using traditional processing methods. The processing of this trench, if not by cutting knife slot, so you want to use at least two other knife, as many as four kinds. Using two or four knife, the bottom of the trench offset to match each other and perfect mix. On the contrary, the symmetric square-shoulder grooving knife allows cutting on both sides of the sidewall and the bottom of the trench, and a single set of bias tool can be. This method of programming, control and adjustment relatively easy, even a relatively narrow grooving knife (width 0.060 in, 1in = 25.4mm) rapid processing of a large part in this way.

Another method is to create a multi-cutting edge grooving knife to complete a variety of processing tasks, a number of processing operations can be completed in the first pass process. In accordance with the traditions and customs, cutting tool manufacturers can use wire drill edm tool grinder manufacturing tool, cutting tool materials for high-speed steel or solid carbide blank. Performance of the tool is good but the problem is with the cutting tool increases, the wear rate faster than any other tool; such tool with greater rigidity and strength requirements than single-point tool, so The best surface roughness may be a major challenge they face. In addition, the fracture of the tool must be immediately from the production site cleaning out, and all surfaces must be re-processed. This requires the will to remove the tool from the machine tool, and then install the replacement tool. Carbide tool is a big step forward, its performance is superior to high-speed steel tools, but this carbide tool surface coating, EDM machining, may be because the loss of cobalt weaken its processing properties.

Order to make the tool to be able to perform a variety of processing tasks, there are two ways is worth considering when the outer diameter of the turning machining parts: The first method is processing the groove cutting tool, making it a single point outside the diameter cutting tools for machining operations is something meaningful (Figure 1); The second method is the tool manufacturing tools to a variety of processing tasks can be completed in the first pass process.

Development of new tools

To make this concept into a modern concept, ThinBit developed the Design-A-the Groove Series multifunction and a knife to go grooving knife, this tool will be of modular design and standardization of carbide carbide blade together. Provide users with the required tool type, the company according to the required manufacturing such a tool. Inlay blade knife, they require low strength, but a higher surface quality than the traditional tools for processing. Moreover, the inserts can guarantee that the tool wear faster local area be replaced individually, which allows the tool to retain the original location on the machine, simply replace the insert, you can make the machine continue to run. This concept provides the conditions for the selection of different grades of carbide alloy tool in order to to change chipbreakers geometry to solve the chip formation, wire EDM or using the tool grinder to cut the rough is unable to do this .
