Woodworking Bottom-Clearing Milling Cutter

Zhongyeda high-quality woodworking bottom-clearing milling cutter is mainly used for panel splicing in furniture manufacturing, door leaf bottom cleaning in wooden door production, and bottom flattening after wooden crafts carving. It can efficiently and accurately clean the bottom of the workpiece, providing a good foundation for subsequent processing and assembly.

Structural design

1. Blade structure: Common ones are double-blade and three-blade structures. The traditional double-blade bottom milling cutter is to process two carbide blades and the base together through high frequency and brazing; the new three-blade bottom milling cutter has a first blade, a second blade and a third blade on the working surface of the cutter head. The cutter head includes three mounting parts, which are vertically connected to each other, so that the entire cutter head is projected as a Z-shaped structure. This structure is conducive to milling feed and can improve the toughness, cutting ability and efficiency of the cutter head.

2. Chip removal design: Some bottom milling cutters are equipped with chip removal grooves. For example, the chip removal grooves of the three-blade bottom milling cutter are usually opened on the surface of the second mounting part, and one side is through-set to facilitate the discharge of wood chips, reduce the impact of wood chips on the cutting process, and improve the milling effect6.

3. Shank design: The shank diameter of the woodworking bottom milling cutter has a variety of specifications, the common ones are 2.35mm, 3.0mm, 4.0mm, 6.0mm, etc., which can be selected according to different woodworking tools and processing requirements.

Working Principle

The bottom-clearing milling cutter is installed on woodworking engraving machines, trimming machines and other equipment. Through high-speed rotation, the blade contacts the wood surface and cuts off the excess part of the wood, thereby realizing functions such as grooving and bottom-clearing. Due to its special blade design, it can better control the cutting depth and direction during the milling process, ensure that the bottom of the groove is flat and smooth, and achieve the purpose of bottom-clearing.

Product Use

1. Grooving and bottom-clearing: Mainly used to mill grooves of various widths and depths on wood, such as grooves for installing hardware such as hinges and handles, and mortise and tenon grooves for splicing wooden boards. During the grooving process, the bottom-clearing milling cutter can directly perform oblique processing to clean and level the bottom of the groove without additional trimming.

2. Leveling wood: With a simple fixture, it can be used to level the surface of wood, partially replacing the function of the electric planer. For some situations where there is no electric planer or the electric planer is not used well, the bottom-clearing cutter can be used to mill the wood surface flat, but it may take multiple millings to achieve the ideal effect.

Product Advantages

1. Prevent material tearing and edge collapse: Some bottom-clearing milling cutters adopt an axial angle design with staggered arrangement up and down, which can effectively prevent material tearing and edge collapse, thereby ensuring excellent cutting results and making the edges of processed wood smoother and neater.

2. Improve processing accuracy: It can accurately control the cutting depth and width, ensure the dimensional accuracy of grooving and bottom clearing, and meet the high-precision requirements of different woodworking projects, especially suitable for furniture making, wood carving and other fields with high dimensional accuracy requirements.

3. Extend tool life: High-quality bottom-clearing milling cutters use high-performance tool materials, such as cemented carbide, etc., with high hardness and wear resistance, and can withstand high-speed cutting and long-term use. Wear, thereby extending the service life of the tool and reducing processing costs.

Applicable scenarios

1. Furniture manufacturing: In the production process of furniture, it is used to make drawer grooves, cabinet door installation grooves, mortise and tenon structures, etc., to ensure the assembly accuracy and stability of furniture.

2. Woodworking DIY: It is suitable for woodworking enthusiasts to make handmade products, such as making small wooden boxes, wood carvings, wooden ornaments, etc., which can help them realize various creative designs and make exquisite woodworking products.

3. Door and window production: used for mortise and tenon processing, frame trimming, etc. of doors and windows to improve the sealing and aesthetics of doors and windows.
