1. The woodworking engraving machine tool holder has good contact with the jacket; the jacket should be firmly clamped to the holder. If the jacket is used for a long time, the inner hole is deformed, and the jacket must be replaced immediately.
2, select the appropriate woodworking engraving machine tool jacket size; can not choose a cross-section, not round, wear, the inner hole has a tapered tool holder, otherwise it will cause the handle to vibrate, the engraving does not achieve the desired effect.
3. When using the woodworking engraving machine, the thickness of the machining should not exceed the thickness that the cutting edge can cut, otherwise the broken knife will appear.
4. Always check the toughness of the woodworking engraving machine tool; if it is blunt, please replace it immediately to avoid the occurrence of broken knife.
5. For cutting of different materials, the cutting speed should be adjusted reasonably. The recommended speed of cutting should be balanced, and the speed should be kept as consistent as possible to achieve better results. If the cutting is too long, it should not stay, and it should be done in one go.
6, the tool should use a special cleaning agent to remove dirt, butter can prevent the tool from rusting. The tool cannot be polished or changed in shape.
Only by mastering the correct use of woodworking engraving machine tools can the woodworking engraving machine shine more and prolong the life of the woodworking engraving machine tool.
Woodworking cutter selection
1. Determine the main technical parameters of the milling cutter: tool outer diameter, machining thickness, central aperture Other technical parameters: number of teeth, direction of rotation, speed of rotation, feed rate, clamping method, tooth material.
2. Select the structural form of the milling cutter: According to the nature and requirements of the cutting object, the overall milling cutter, the welding integrated cutter, the assembly milling cutter and the combined milling cutter are selected from the technical and economic aspects.
3. Selection of milling cutter rotation direction: The milling cutter rotation direction is determined according to the rotation direction of the machining machine spindle and the relative position of the cutter shaft and the feeding workpiece. Whether it is an integral milling cutter or an assembly milling cutter, the cutting edge is opposite to the milling cutter. The inclination of the radius determines the direction of rotation of the milling cutter.
4. Cutting tool selection: The cutting amount of the milling cutter includes the cutting speed of the milling cutter, the feed rate of the workpiece and the milling depth. The cutting speed of the milling cutter depends on the milling cutter speed and the radius of the milling cutter. The feed rate of the workpiece depends on the quality of the machined surface. The surface roughness of the workpiece to be cut depends largely on the feed per tooth of the milling cutter during the cutting process. The feed per tooth is too large, the machining surface is too rough, the feed per tooth is too small, and the machined surface will burn. The focus phenomenon, so the feed per tooth of the milling cutter must be appropriate.
5. Stability of milling operation: The stability of milling operation is the basis for ensuring machining accuracy and surface quality. This includes two aspects: First, the milling cutter is vibrated by external force during cutting; second, the milling cutter is deformed by external force.
6. Safety of milling machining: The safety of milling machining includes milling speed limit, chip thickness limitation, profile cutter height limit and assembly cutter blade thickness and extension limit.
Wood cutting is characterized by high-speed cutting, and the milling speed of the milling cutter is more than 3000 rpm. High-speed cutting provides high productivity and smooth surface quality for wood cutting. At the same time, it also brings a series of safety problems. Therefore, when the spindle speed of the milling machine reaches 9000 rpm, the assembly milling cutter should be prohibited except for the shank milling cutter with a tool smaller than 16 mm. Conduct a rigorous inspection of the flaw. Chip thickness limitation is a necessary measure to ensure that the milling cutter feeds too much and causes a serious overload of the milling cutter.
For the forming cutter, the contour contour height value is closely related to the milling cutter clamping method, the cutting workpiece thickness, and the diameter of the milling cutter. After the thickness of the machined workpiece, the diameter of the milling cutter and the central aperture are determined, the height of the cutter profile reflects the strength and stiffness of the milling cutter itself and the ability to withstand the cutting resistance. Therefore, the height of the profile must be limited to ensure the safety of the cutter. The design of the insert milling cutter body must take into account the clamping problem of the insert. Whether it is a cylindrical cutter body or a disc-shaped cutter body, the insert clamping form must ensure that a sufficient clamping force can be provided to resist the centrifugal force of the swing. .
The above is the correct use of woodworking engraving machine tools for woodworking engraving machine manufacturers, I hope to be helpful to everyone.
