Introduction to basic technical parameters and application knowledge of carbide woodworking router cutter

1 Introduction

Cemented carbide woodworking router cutter, referred to as router cutter for short, is mainly used in the production of wooden furniture. It is a handle type cutter used in some patterns that cannot be produced by large machines and small batch production.

In the process of tool machining, the router cutter tool rotates at high speed, and the workpiece to be machined does not rotate. The cutting motion is carried out on its surface to achieve the purpose of tool machining.

2. Characteristics of milling cutter

Cemented carbide router cutters should have strong hardness, excellent wear resistance, sufficient strength, necessary toughness and certain processability (such as welding, heat treatment, cutting and grinding performance). At the same time, the tool also needs to ensure that the blade has enough sharpness to ensure smooth cutting and good machining surface.

3 applicable machine for router cutter

It is widely used in floor engraving (with the handle facing down and rotating counterclockwise), hanging router (with the handle facing up and rotating clockwise), portable engraving machine and trimming machine, bakelite milling, CNC machining center and engraving machine, etc.

4. Application scope of router cutter

It is commonly used for direct cutting of solid wood and various man-made materials, milling of workpiece joint surface, slotting and profiling milling.

5 diameter of the handle of woodworking router cutter

The router cutter with cutting diameter equal to or less than 1/4 inch shall have a 1/4 inch diameter handle, and the router cutter with 1/4 ~ 1/2 inch diameter shall have a 1/2 inch diameter handle. There are also metric handles 6mm and 12mm. If the chuck of the router allows, the tool with large diameter should use a 3/4 inch diameter handle. Most CNC router machines allow the use of large-diameter tool handles, which makes the machine safer. All cutting tools should have an accurate tool handle. Any ungrinded tool handle can not be well matched with the collet. If possible, the diameter of the tool shank should be equal to or greater than the diameter of the cutting tool.

6 classification of router cutters

According to the processing pattern and function of the router cutter, it can be divided into the following categories:

(1) Carbide woodworking straight drilling cutting tools

(2) Carbide trimming profiling woodworking milling cutter

(3) Carbide carving woodworking milling cutter

(4) Carbide lace forming woodworking milling cutter

(5) Carbide handrail line woodworking milling cutter

(6) Carbide side slotting edge inlaying woodworking milling cutter

(7) Cemented carbide tenon type woodworking milling cutter

(8) Woodworking milling cutter for hard alloy door panel processing

(9) Carbide mortise and tenon woodworking milling cutter

(10) Cutting edge integral alloy woodworking milling cutter

7 key points for inspection of carbide woodworking router cutter

(1) Surface roughness: handle Ra1.6 μ m;  Front edge Ra0.8 μ m;  S curve blade back angle rz3.2 μ m;  The geometric dimension accuracy is qualified;

(2) The cutting edge of the router shall be sharp, and the surface of the blade shall be free of defects such as black skin, crack, broken edge and grinding burn, and the surface of the router shall be free of scratch, rust, etc;

(3) Geometric tolerance: the radial circular runout tolerance of the edge curve to the axis of the handle is 0.02 mm; The consistency tolerance of the edge curve is 0.1mm (check any same part of the edge curve, and the expressed value in thousands is within the range of 0.1).

(4) The router cutter blade material is made of K30 or other cemented carbide materials with performance not lower than that specified in GB 2075, and the cutter body is made of

It is made of 45 steel or other materials with performance not lower than that specified in GB 699, and its handle hardness is 30 ~ 35hrc.

(5) The weld shear strength of the router blade shall not be less than 120MPa.

8 precautions for use of woodworking router cutter:

(1) According to different processing materials, appropriate carbide woodworking router cutters are selected. Under normal circumstances, the cutters rotate clockwise;

(2) The high-precision jacket must be selected. If it cannot meet the configuration requirements due to wear or other conditions, it must be replaced immediately.

(3) When clamping the carbide woodworking router cutter, pay attention to avoid slag inclusion and the clamping depth should meet the requirements. For example, the clamping depth of 1/2 handle (12.7mm) shall reach 24mm to ensure its due bearing capacity. Generally, the depth of the clamping handle shall reach that the tool handle length is more than 4/5 of the length.

(4) Select the matching rotating speed and pushing speed according to the size and processing amount of the carbide woodworking router, and keep the uniform speed. Do not stop in the cutting process.

(5) The carbide woodworking and milling tools shall be replaced in time after passivation.

(6) Users should pay attention to safety protection when working with carbide woodworking router cutter.
