Abstract

The utility model discloses a milling cutter with a nano superhard coating, comprising a cutter handle, wherein one end of the cutter handle extends to form a milling head, a base layer, a transition layer and a surface layer are coated outside the milling head in turn, the basal layer is a titanium-aluminum alloy layer, the transition layer is a titanium carbide nitride layer and the surface layer is a titanium aluminide nitride (TiAlN) coating layer. The milling cutter with the nano superhard coating can adapt to various severe conditions, and has relatively long service life.

Description

Nano superhard coating milling cutter

Technical field

The utility model relates to a kind of milling cutter, relates in particular to a kind of nano superhard coating milling cutter.

Background technology

Existing milling cutter versatility is stronger, and chip removal is smooth, service life is low, process high rigidity and the not good problems such as material of difficult cutting surface quality but exist.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of nano superhard coating milling cutter, can be adapted to various harsh conditions, has higher service life.

The utility model for the technical scheme that solves its technical problem and adopt is: a kind of nano superhard coating milling cutter, comprise handle of a knife, one end of handle of a knife extends to form milling head, outside described milling head, be coated with basal layer, transition zone and top layer successively, described basal layer is titanium-aluminium alloy layer (TiAl), described transition zone is TiCN layer (TiCN), and described top layer is nitrogen titanium aluminide plated film layer (AlTiN).

As further improvement of the utility model, described titanium-aluminium alloy layer thickness is 100～200nm; Described TiCN layer thickness is 100～400nm; Described nitrogen titanium aluminide plated film layer thickness is 200～1000nm.

The beneficial effects of the utility model are: good by going out adhesive force in brill body surface preparation, it is low to rub, the hardness height, the high temperature resistant functional coat that waits can guarantee milling cutter when the High-speed machining material, and nothing bonds, chip removal is unobstructed, thereby guarantee under various harsh machining conditions, the efficient height, reliable in quality, the life-span can be improved 1-2 doubly simultaneously.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is milling head cross-sectional view described in the utility model.

By reference to the accompanying drawings, make the following instructions:

1---handle of a knife 2---milling head

3---basal layer 4---transition zone

5---the top layer

The specific embodiment

By reference to the accompanying drawings; the utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, and namely the simple equivalent of being done with the utility model claim and description in every case changes and modifies, and all still belongs within the utility model patent covering scope.

As shown in Figure 1, 2, a kind of nano superhard coating milling cutter, comprise handle of a knife 1, one end of handle of a knife extends to form milling head 2, outside described milling head, be coated with basal layer 3, transition zone 4 and top layer 5 successively, described basal layer is titanium-aluminium alloy layer (TiAl), and described transition zone is TiCN layer (TiCN), and described top layer is nitrogen titanium aluminide plated film layer (AlTiN).Wherein, basal layer plays and improves the coating adhesion effect, and transition zone plays the connection supporting role, and the top layer has characteristics such as high rigidity (3200HV), high temperature resistant, chemical stability height.After the milling head of milling cutter applied this coating, structure was finer and close, and the surface is brighter and cleaner, thickness is even, and internal stress reduces, and friction is little when cutting simultaneously, high temperature resistant, wear-resistant, thus guarantee that milling cutter under various harsh machining conditions, has better cutting force and higher service life.

Preferably, described titanium-aluminium alloy layer thickness is 100～200nm; Described TiCN layer thickness is 100～400nm; Described nitrogen titanium aluminide plated film layer thickness is 200～1000nm.
