Description

A machine clamp type CNC milling cutter

technical field

The utility model relates to a wood cutting tool, in particular to a machine clip type numerical control milling cutter.

Background technique

With the rapid development of modern wood processing machinery, more and more CNC equipment has entered the field of furniture manufacturing, and the corresponding requirements for cutting tools are getting higher and higher. Traditional milling cutters are mostly welded with carbide blades and steel bodies. , Cracks are likely to be caused during the blade welding process, and the requirements for welding skilled workers are also high. The manufacturing cost of the tool is high, and it is difficult to sharpen the tool in the furniture factory. If the tool is worn out, the entire product will be scrapped.

Utility model content

The purpose of the utility model is to provide a clamp-type numerical control milling cutter that can be used repeatedly, has a long service life and high processing precision.

In order to achieve the purpose of the utility model, the utility model adopts the following technical scheme: the clamp-type CNC milling cutter includes a handle, a cutter body, and a blade in sequence, and is characterized in that: the blade is provided with several through holes, and the screw passes through The through hole fixes the blade on the cutter body, the cutter body is provided with a groove, and the cutter body is provided with a chip removal groove, and the blade is a blade with a double edge, and both sides of the blade are provided with blades. The mouth, after serious wear on one side, you can change a blade for secondary use.

Preferably, the cutter body is provided with a beveled groove,

Preferably, the bevel angle is 50°-60°.

Preferably, the cutting edge of the blade is provided with a blade angle, and the angle of the blade is 50°-60°. During the assembly process, positioning is performed according to the bevel angle and the angle of the blade, which saves assembly time and reduces assembly errors, ensuring that the blade after assembly The concentricity is within 0.02.

Preferably, the cutter body is provided with an arc-shaped chip removal groove, which is beneficial to the smooth discharge of wood chips, and is less prone to jamming due to blockage of wood chips at the limit cutting depth.

Preferably, the blade is made of cemented carbide, because cemented carbide has the advantages of high hardness, strong wear resistance, and good heat resistance, which improves the service life of the tool.

Preferably, the precision requirement of the tool handle is h6, which is suitable for the chuck of the CNC machining center.

The beneficial effects of the utility model: the cemented carbide blade is clamped on the cutter body by means of screw fixing, and after one side of the cutter wears out, the service life of the cutter can be extended by unscrewing the screw, changing the direction of the blade or replacing the blade ;The tool clamped by the mechanical clamping method has good cutting performance, long life, fast tool change, high efficiency and high precision of the machined plane contour, saving manpower. resulting labor costs.
