A wood engraving machine is a hand tool or power tool that workers use to hollow out an area in relatively rigid materials such as wood or plastic. Wood engraving machines are mainly used for woodworking, especially joinery. Wood engraving machines are usually hand-held or fixed-cut ends in an engraving table. The type of hand tool for the engraving machine is the original form. This is a special type of hand planer that has a wide base and a narrow blade that extends far beyond the floor (so it is called the "old woman's teeth"). The power tool form of a router with an electric motor spindle is now a more common form. Now, the manual tool version is mainly used for engraving machine plane engraving, which still provides some advantages over power tools for some tasks. Some workers consider the wood engraving machine to be one of the most versatile woodworking tools. [1] The wood engraving machine realizes the advantages of numerical control (computer numerical control).
Associated with the engraving machine is a smaller, lighter version specifically designed to trim laminates. It can be used for smaller general engraving work. For example, a suitable clamp can be used to open the door hinge and open the lock panel. Even the rotating tool can be used as a wood engraving machine when the correct bit and attachment (such as a plastic engraving machine base) are attached.
Wood engraving machine history
Before the advent of wood engraving machines, people often used hand tools, especially pattern makers and stair makers. The first hand-held wood engraving machine was invented in 1915 [2], a jet engine wood engraving machine called Onsruters. The name comes from the inventor's last name "Onsrud" and "router". Onsruter combined a router plane with an end mill to create the first handheld wood engraving machine. Onsruter's idea was to start when a railway company decided to use the exhaust from the engine to drive the headlights of the steam locomotive. Oscar Ansrud and his son Rudy submitted a design to generate electricity for a wind turbine, but did not win the contract. A few months later, Rudy Onsrud told a friend that his frustration was done in a trench in the bottom of a wicker chair with an engraving plane. He suddenly realized that he could redesign the air turbine to run in compressed air and then rotate a modified end mill to upset the slot. The improved end mill must be rotated at 30,000 rpm instead of a 3000 rpm milling machine to cut wood without burning. Compared to conventional end mills, the drill requires a steeper angle of inclination and a clearance angle to remove the chip. These new bits are called engraving machine bits or engraving machines (UK). A one-step improvement resulted in a plug-in engraving machine that was invented around 1949 by the German ELU (now part of DeWalt). This is a better choice for many types of work. Since the 1960s, the power tool form of engraving machines has become a more common form. Modern wood engraving machines are often used to replace traditional molding surfaces or spindle molding machines for edge trimming (molding) of wood.
Wood engraving machine process
Wiring is a process of cutting, trimming, and shaping a variety of materials such as wood, metal, and plastic.
Chip formation
The modern plug-in engraving machine showing the dedusting tube is conceptually similar to engraving and milling, while the end-face milling cutter can be used for engraving machines, but in terms of mechanics, engraving wood and milling metal are different. The formation of the chips is different, so the optimal tool geometry is different. Routing is suitable for relatively fragile materials, especially wood. Since these materials are weak in small sections, the wood engraving machine can run at very high speeds, so even a small wood engraving machine may be cut off quickly. Due to the inertia at these high speeds, the conventional type I sawdust cutting mechanism cannot be realized. The edge angle of the tool is blunt, close to 90°, so the form of the type III chip, with the dust generated by the waste. This dust is harmful to the respiratory system, even if it is harmless. The force on the cutter is very light, so the engraving machine may be hand-held. When milling metal, the material has relative ductility and maintains strength even at very small dimensions. A type II wafer form, and waste can be applied continuously. The milling force is high, so the milling machine must be strong and strong, usually a solid structure of cast iron. Intermediate materials, such as plastics, sometimes soft aluminum, can be cut in any way, although processing aluminum is often a temporary expedient, not a production process, and it is very noisy and harsh on tools.
Wood engraving machine process features
Makita laminate fine-tuning engraving is usually limited to soft metals (aluminum, etc.) and rigid non-metals. Specially designed tools are used for a variety of patterns, cuts and trims. Manual and machine control/auxiliary engraving machines are now common.
