Twisted columns are generally monolithic columns, at least the cylindrical part is integral, because the twisted columns after segmentation processing, when splicing, there will be multiple seams on each splicing surface, and there is slight error in processing. (This is inevitable in processing), which will cause the seam to be biased and affect the decorative effect. When processing some high-strength (such as more than 4m) twist columns, if it is difficult to mine or transport the ultra-long monolithic stone, several stones can be spliced ​​into a monolithic column before being processed into a monolithic column. As long as the processing length of the equipment can meet the requirements, and the material and billet preparation requirements of the splicing stone processing twisted column are the same as those of the ordinary cylinder, the processing procedure and requirements are the same as the corresponding processes and requirements for processing the ordinary cylinder.
The twisted column can be machined using a CNC lathe with a diamond saw blade power head that can rotate from 0 to 360 degrees (0-90 degrees), a multi-function CNC machining center. For some tactile columns with special tooth shape, cylindrical end mills can also be used for correction forming. Generally, the diamond saw blade can fully meet the needs of the forming process of the twist column. Polishing twisted columns is difficult. At present, the problem of polishing abrasives cannot be solved. If a torsion column needs to be polished, manual polishing with soft abrasive blades is still a practical method. For some twist columns with large pitch, the cylinder on the outer surface is still cylindrical, and these parts of the twist column can be polished by polishing ordinary cylinders.
When using a lathe to process a twisted column, the end face support method and requirements of the blank are the same as those of a normal cylinder.
When forming the spiral of the outer surface of the twisted column, the processing program can be programmed for each twist column using the graphic design software installed on the numerical control device. When processing a multi-head helical twist column, it is generally started by processing a spiral. When the spiral is processed, another spiral is processed until the end of the processing. The position of the spiral at the starting point of the starting end face is automatically determined by controlling the angle of rotation of the cylindrical blank.
Abstract Twisted column is also called spiral column, and its outer surface has a spiral shape. The spiral surface of the outer surface of the spiral column has a shape of a single head, a double head and a multi-head; the shape of the spiral tooth tip has a shape such as a circular arc, a straight line and a circular arc line; the size of the pitch is not specific according to the design modeling requirements. ...
The twisted column is also called a spiral column, and its outer surface has a spiral shape. The spiral surface of the outer surface of the spiral column has a shape of a single head, a double head and a multi-head; the shape of the spiral tooth tip has a shape such as a circular arc, a straight line and a circular arc line; the size of the pitch is not specific according to the design modeling requirements. Claim. According to the size of the cross section of the twisted column, it can be divided into equal-diameter twisted columns with equal sections and drum-shaped twisted columns and conical twisted columns with unequal sections.
