Description

High speed CBN indexable disc milling cutter

technical field

The utility model relates to a machining cutter, in particular to a high-speed CBN indexable disc milling cutter.

Background technique

A milling cutter is a rotating tool with one or more teeth for milling operations. When working, each knife tooth cuts off the allowance of the workpiece intermittently in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines.

For the existing disk milling cutter, there are the following problems. The design of the connection structure between the cutter head and the blade is unreasonable, and the adjustment is inconvenient. It is scrapped, the service life is short, the cost is too high, and alloy blades are mostly used, and the processing performance and efficiency are low.

Utility model content

The purpose of this utility model is to provide a high-speed CBN indexable disc milling cutter with reasonable structure design, convenient adjustment, and long service life for grinding in view of the above-mentioned existing problems and deficiencies.

Adopt above-mentioned technical scheme, the beneficial effect that obtains is:

A high-speed CBN indexable disc milling cutter, including a tool handle, a cutter disc and a blade arranged on the cutter disc, a series of tool seats are uniformly distributed on the outer edge of the front end of the cutter disc, and the tool seats are A radial adjustment groove is provided on the front end of the corresponding cutter head, and an axial adjustment groove and a pressing block groove are provided on the edge side of the cutter seat corresponding to the cutter head, and the bottom of the radial adjustment groove, the axial adjustment groove, and the pressing block groove There are screw holes, and the radial adjustment block, the axial adjustment block and the pressure block are respectively matched in the radial adjustment groove, the axial adjustment groove and the pressure block groove, and the radial adjustment block, the axial adjustment block and the pressure block There are screw holes corresponding to the radial adjustment groove, the axial adjustment groove and the pressure block groove respectively on the top, and matching double-headed screws are provided.

The blade is in the shape of a cuboid, the cross section of the blade is square, and the material of the blade is cubic boron nitride.

The number of tool holders on the cutter head is 8 evenly distributed around the circumference.

The middle part of the cutter head is provided with a screw hole matched with the handle of the cutter and is fixedly connected by bolts.

Adopt above-mentioned technical scheme, the beneficial effect that obtains is:

The utility model, through the structural design of the cutter head and the blade, and the new innovation of its connection and positioning adjustment structure, enables the blade to be adjusted in both radial and axial directions during the fixed installation process, so that the end teeth of the blade can be guaranteed The runout and outer diameter runout are below 0.005, which ensures that the uniformly distributed blades can receive the same wear and prolong the service life. At the same time, the 8 corners of the blade can participate in cutting and can be ground, which greatly improves its service life. Reduced processing costs.

Detailed ways

The specific embodiment of the utility model is described in detail below in conjunction with accompanying drawing.

Referring to Fig. 1-Fig. 7, a high-speed CBN indexable disc milling cutter of the present invention includes a handle 1, a cutter head 2 and a blade 4 arranged on the cutter head 2, and the middle part of the cutter head is provided with a knife The handle is matched with the screw hole connected and fixedly connected by bolts. The outer edge of the front end of the cutter head 2 is evenly distributed around the circumference and provided with 8 knife seats 3. To the adjustment groove 5, the edge side of the knife seat 3 corresponding to the cutter head 2 is provided with an axial adjustment groove 6 and a briquetting groove 7, and the bottoms of the radial adjustment groove 5, the axial adjustment groove 6, and the briquetting groove 7 are all provided with There are screw holes 8, and the radial adjustment block 9, the axial adjustment block 10 and the pressure block 11 are respectively matched in the radial adjustment groove 5, the axial adjustment groove 6, and the pressure block groove 7. The radial adjustment block 9, the shaft Screw holes corresponding to the radial adjustment groove 5, the axial adjustment groove 6, and the pressure block groove 7 are opened on the adjustment block 10 and the pressure block 11, and matching double-headed screws are provided. The blade 4 is a cuboid. The cross section of the blade 4 is square, and the material of the blade 4 is cubic boron nitride.

The utility model adopts the structural design of the cutter head and the blade, and the new innovation of its connection and positioning adjustment structure, so that the blade can be adjusted in two directions, radial and axial, during the fixed installation process, so that the beating of the end teeth of the blade can be guaranteed. Below 0.005, it ensures that the uniformly distributed blades can receive the same wear and prolong the service life. At the same time, the 8 corners of the blade can be cut and can be reground, which greatly improves its service life and reduces processing costs.
