At present, the range of tool systems has been expanded by the EVH type multi-purpose milling cutter and the EXH type large feed milling cutter. As a result, the HYBRID-TAC-MILL series of milling cutters cover a wide processing range of steel or non-ferrous metal parts. According to the manufacturer, the cutter of the tool system is more efficient than the competitor's tool.
The basic idea is that the precision cutting edge of a spiral solid carbide milling cutter is replaced by a blade, so that the precision of a solid carbide milling cutter is combined with the economics of an indexable insert cutter. . At the same time, a new generation of milling cutters covers a range of diameters above the medium size. Here, the current solid carbide milling cutter can be economically replaced.
In this way, the new TUNGALOY milling cutters are especially used in milling, milling, milling, vertical milling and drilling, helical interpolation milling, milling of workpieces at inclined angles and milling holes. Is a suitable choice.
High precision EPH milling cutter for 40% durability
The HYBRID-TAC-MILL series of EPH milling cutters are well-suited for steel and non-ferrous metals with precise 90 degree steps and long cutting edges that are particularly sharp and replaceable with large helix angles. Milling of parts. The coating also makes it possible to make many varieties of milling cutters, that is to say, all HYBRID-TAC-MILL milling cutters used for steel machining are not AH730PVD coatings or DLCDS1200 coatings for machining workpieces of aluminum alloys and other non-ferrous materials. .
The EPH milling cutter, which is known for its excellent processing capability, is used for machining steel parts. Most of its tool nose radius is 0.2-2.0MM. It is used to machine aluminum alloy workpieces with a tool nose radius of 0.0-2.0. MM. For example, when milling C15E carburized steel, EPH milling cutters are processed with 1000 workpieces, and the processed workpieces are shown to be within the specified tolerances. Competitor milling cutters need to be replaced with new ones after machining 700 workpieces. Knife. The use of EPH milling cutters, in addition to improving tool durability by 40%, also greatly improves the processing quality of the workpiece surface. Because the cutting force generated during milling is small and the noise of the machine tool is reduced.
Multi-function EVH milling cutter and high efficiency EXH milling cutter
The EVH-90? milling cutter is a multi-purpose milling cutter with an internal cooling passage for the cutter body and a central blade for a wide range of applications. The positive yaw angle of the indexable insert reduces the cutting force and results in a vibration-free cutting process. Large chip flutes with internal but cold channels provide excellent chip evacuation even when cut into the workpiece at an oblique angle.
The EXH type milling cutter is a "sprinter" of the HYBRID-TAC-MILL series. This high-feed milling cutter has a positive yaw angle, a sharp cutting edge and a structure with a central cutting edge, which facilitates a higher material removal in the diameter range of 10 mm or more. This tool structure with internal cooling channels can be used with a feed per tooth up to 0.6 mm and can be used for a wide range of applications. The particularly high production efficiency shows that the EXH type milling cutter can use a cutting amount of 0.6 mm for FZ during roughing. In the mold making process, the EXH type milling cutter can show its advantages even when milling the thin-walled profile of the graphite material. Unlike many solid carbide milling cutters, this tool produces virtually no vibration even when milling with a large depth of cut.
Even when milling CK45 (a high-quality steel with low phosphorus and sulfur, its tensile strength is 640N/MM2), it has excellent results: 250% more durable than solid carbide milling cutters. Degree is the best illustration of the performance of this tool. Moreover, this was obtained under the conditions of a cutting speed of 40 M/MIN, a cutting depth of 0.4 mm, and a feed amount per tooth of 0.2 MM/Z.
Milling cutter clamping precision and reliability
The HYBRID-TAC-MILL cutter does not have to be reground, which reduces tooling costs and logistics costs. The indexable insert can be replaced directly on the machine, saving auxiliary time. The tool does not need to be re-measured, and this measurement is required for a solid carbide milling cutter. To this end, the new toolholder mechanism has a high degree of precision on the seat on which the indexable insert is mounted.
For EPH milling cutters, the DD-FIT clamping system uses two screws to simultaneously clamp the indexable insert. The tilting arrangement of the screws, even under the action of very high centrifugal forces, firmly presses the indexable insert and maintains precise positioning.
For EVH and EXH milling cutters, the SS-FIT clamping mechanism is used when clamping the indexable insert. The SS-FIT system ensures a high working stability of the milling cutter due to the large blade cross section and the threaded side of the blade seat on which the insert is mounted. With both systems, milling cutters can now run at 15,000 rpm. This enables a very high processing speed or a large amount of material removal.
