How to choose better woodworking engraving machine woodworking milling cutters and milling cutter selection method - - 【 】 Engraving machine _ _ _ _ CNC woodworking engraving machine engraving machine engraving

woodworking milling cutters are commonly used engraving machine accessories, are of great help to choose a good milling cutter for machining, the simple engraving machine below explain the method of choosing woodworking milling cutters, for your reference.








one, by the nature of the cutting material





object is solid wood and wooden cutting of wood composite materials. Solid wood and can be divided into soft materials, hard materials and modification of wood, etc. ; Wood composite materials including plywood, LVL, particle board, directional particieboard, large particle board, gypsum particleboard, cement particle board, medium density fiberboard (MDF), high density fiberboard, hardboard, joinery board, glued timber, etc. Some kinds of wood or wood composites workpiece pass single side or double side cover decoration processing.





2, cutting direction





solid wood cutting, according to the blade relative to the direction of the wood fiber wood cutting can be divided into vertical and horizontal, end to and longitudinal end to, lateral and horizontal side to cut.





3, tool rotation direction and the direction of feed





according to the direction of machine tool axis rotation and workpiece feed of wood direction, to determine the cutter blade on the tilt direction.





4, cutting tool and the workpiece stability





the cutting tool and the workpiece in the machining process stability includes several aspects of content, the stability of the workpiece is refers to the workpiece in cutting wood smooth feed without beating. Strengthen the work-piece stability measures mainly include lower center of gravity and increase the contact area.





5, the processing surface quality requirements





wood workpiece surface quality including surface roughness, geometry size and shape the location accuracy.





cutter selection of





a, the main technical parameters of milling cutter:





the main parameters of woodworking milling cutter, cutter diameter, thickness, processing center bore





the other technical parameters: knife tooth number, turning direction, turning speed, feed speed, clamping, blade material.





2, select the structure of cutter





according to the nature and requirements of machining object, from KW8 - 9 uy two aspects of technical and economic comprehensive consider to choose integral milling cutter, welding whole milling cutter, cutter assembly milling cutter and combination.





3, the choice of milling cutter rotary direction





cutter turning direction is based on processing machinery and axis and spindle rotation direction and feed the relative position of the workpiece, both the overall milling cutter, or assembled milling cutter, cutting blade relative cutter radius Angle determines the direction of cutter rotation.





4, milling cutter, cutting dosage choose





cutting parameter including cutting speed of the milling cutter of the milling cutter, workpiece and feed speed of milling depth. Cutting speed depends on the milling cutter of the milling cutter rotating speed and radius of the milling cutter. The workpiece feeding speed depends on the requirement for the quality of machining surface. By cutting the surface roughness of the workpiece depends largely on each tooth cutter feeding, in the process of cutting per tooth feed is too large, the processing surface is too rough, each tooth feed is too small, processing surface will appear burning phenomenon, so each tooth of the milling cutter feeding must be appropriate.





five, the stability of the milling cutter





stability of the milling cutter is the basis of the guarantee machining precision and surface quality. This includes two aspects: the contents of a milling cutter in machining is due to the external force excitation of vibration; Secondly, the milling cutter deformation under the action of external force.





6, the safety of the milling cutter machining





milling processing including safety of milling cutter rotary speed limit, chip thickness, forming milling cutter profile height restrictions and cutter blade thickness and stretch out the amount limit for assembling, etc.





timber machining is characteristic of high speed cutting, the turning speed of the milling cutter in more than 3000 RPM, high speed cutting for wood cutting processing of high production efficiency and smooth surface quality. At the same time, also brought a series of security problems, so when the milling machine tool spindle speed reaches 9000 RPM, woodworking engraving machine in addition to the cutting tool is less than 16 mm shank cutter, assembled milling cutter, and should be banned for welding the overall inspection welding seam and strict inspection of the milling cutter.
