With the continuous development of society, more and more people need to use log products, or need to use greener and pollution-free products. So now we need a lot of wood materials. In order to better use and reduce the waste of wood materials, generally, manufacturers will use woodworking machinery four-sided moulders to process and manufacture wood materials.
Why choose four-sided moulders?
Improve the yield of wood.
The four-sided moulder is a one-pass processing machine. The workpiece can be processed to the required size, cross-sectional shape, and surface finish in one pass, avoiding the need for multiple machine tools to repeatedly process multiple times. Each time, a certain amount of cutting must be given to ensure that the indentation caused by the feed mechanism is eliminated during cutting.
Improve product quality and processing accuracy.
The processing of the four-sided moulder improves the required flatness and surface finish of the workpiece and provides the necessary conditions for subsequent processes to ensure processing accuracy. The four-sided moulder is completed in one process, which reduces the number of workpiece clamping and positioning, thereby reducing the processing accuracy error caused by positioning error. Since the four-sided moulder uses mechanical continuous forced pressing and feeding, there is little jumping and displacement during the workpiece cutting process, which also provides a favorable guarantee for improving the processing accuracy in terms of machine tool structure. The feed speed can be adjusted in multiple gears or steplessly according to the material of the processed wood and the amount of cutting, which reduces the processing quality defects caused by excessive cutting amount to a certain extent.
Using a woodworking machinery four-sided moulder can ensure that the wood material is well utilized. At the same time, it can improve the yield of wood materials and improve the quality of the woodworking machinery four-sided moulder, ensuring the processing accuracy of the material during processing. It is a very practical mechanical equipment.
How To Choose a Four-Sided Moulder Machine?
When selecting a machine, it is necessary to consider a main processing direction, take into account the processing requirements of other directions, make overall arrangements, and comprehensively consider the technical requirements and capital investment. A reasonable choice of a specific type of machine tool should meet the most technological processing needs, incur the smallest expenses, and provide the simplest and most convenient operation and maintenance.
- Determine the number of cutter shafts according to the required cross-sectional shape of the workpiece to be processed.
The number of four-sided moulder axes determines the processing capacity of the machine tool and mainly determines the cross-sectional shape of the workpiece that the machine tool can process. Under normal circumstances, workpieces with regular cross-sectional shapes can be processed by four-axis four-sided moulding to meet the requirements. One surface is the profile surface, and the other three surfaces are flat workpieces, which can be processed by a five-axis four-sided moulder.
The processing of workpieces with complex cross-sectional shapes, such as birch grooves, birch heads, and two planes, or line profiles for decoration, requires seven-axis or eight-axis four-sided moulding. - Select the processing capacity of the machine tool according to the possible processing batch.
The processing capacity of the machine tool mainly depends on the feed speed of the machine tool, the speed of the tool shaft, and the cutting power. Generally, when the feed speed is high, the cutting amount, that is, the width and thickness of the cutting, should be small, and the rotation speed of the cutter shaft should be increased.
When the feed speed is low, the cutting amount can be appropriately increased, and the rotation speed of the cutter shaft can be reduced accordingly to meet the requirements of the motor power. But the speed should not be too low, as it will affect the quality of the processed surface.
Within the allowable range of mechanical strength and rigidity, the higher the speed of the machine tool shaft, the better the quality of the machined surface. - Determine the mutual position and feeding method between the machine tool axes according to the size specifications and accuracy requirements of the workpiece to be processed.
The maximum width of the workpiece that can be processed by the four-sided moulder is the main parameter of the machine tool. The section size, width, and height (thickness) of the workpiece determine the limit range of adjustment between the upper and lower horizontal tool axes and the left and right vertical tool axes of the four-sided moulder, as well as the adjustment and positioning accuracy of the tool axis.
In general, each tool axis of the machine tool should not be at the limitation of its adjustable range, and a certain margin should be left, otherwise, it will affect the machining accuracy. Different feeding methods will affect the positioning and compaction of the parts during the machining of the machine tool, thereby affecting the machining accuracy of the workpiece. Normally, for thin and long workpieces with poor rigidity, the pressing force of the pressing rollers of the feeding mechanism should be small, and the pressing rollers should be correspondingly larger. For workpieces with good rigidity such as short square materials, the pressure of the pressing rollers of the feeding mechanism can be increased, and the pressing rollers can be reduced accordingly. - Focus on one product, take into account the development of other products, and choose a machine tool whose process range can be expanded to meet the needs of the future development of the enterprise.
