Besides, it is the most cost-effective general-purpose material featuring good comprehensive mechanical properties, product transparency, electric insulation, thermal insulation, noise elimination, and shock absorption. With the disadvantages of poor thermal stability and poor shock resistance, both hard PVC and soft PVC tend to embrittle when used. <strong>Therefore, the following needs your attention during the CNC machining of the PVC material.<\/strong><\/span><\/p>\n<ul>\n<li><span style=\"font-size: 115%; color: #000000;\">PVC is one of the plastic materials that have poor thermal stability and poor shock resistance compared to the common material POM and tends to embrittle during CNC machining, so attention needs to be paid to cutter selection. The cutters dedicated to PVC should be used, or the degree of surface finish will not meet the requirements on the drawing after machining due to insufficient cutter sharpness.<\/span><\/li>\n<li><span style=\"font-size: 115%; color: #000000;\">Try to use reasonable cutting parameters as well as low rotation speed and low feed speed which are good for the discharge of plastic residues. Otherwise, the plastic residues will stick to the part and affect cooling, leading to adherence to the cutter, part surface abrasion, and cracks or notches on part surfaces.<\/span><\/li>\n<li><span style=\"font-size: 115%; color: #000000;\">Use the dedicated fixture and good protection for the part. Because this part needs to be clamped multiple times during machining and plastics have a lower hardness than metals, both clamping surfaces and clamping forces need to be considered in a reasonable way each time. Otherwise, the part may be knocked off or its surfaces may be damaged due to clamping.<\/span><\/li>\n<li><span style=\"font-size: 115%; color: #000000;\">The omission of any one of the above leads to a great possibility of defective products!<\/span><\/li>\n<\/ul>\n<h2 style=\"text-align: center;\" data-fontsize=\"34\" data-lineheight=\"50\"><span style=\"font-size: 115%; color: #000000;\">Proceso de mecanizado<\/span><\/h2>\n<h3><span style=\"font-size: 115%; color: #000000;\">Machining Sequence:<\/span><\/h3>\n<p><span style=\"font-size: 115%; color: #000000;\"><img alt=\"\" decoding=\"async\" class=\"aligncenter wp-image-3088 size-full\" src=\"https:\/\/yijin.seo2.au\/wp-content\/uploads\/2022\/06\/16405847091.png\" width=\"554\" height=\"123\" \/><\/span><\/p>\n<p><span style=\"font-size: 115%; color: #000000;\"><strong>Machining Equipment:<\/strong>\u00a0CNC turning and CNC milling machine tools<\/span><\/p>\n<p><span style=\"font-size: 115%; color: #000000;\"><strong>Number of cutters:<\/strong>\u00a010<\/span><\/p>\n<p><span style=\"font-size: 115%; color: #000000;\"><strong>Cutter type:<\/strong>\u00a045\u00b0excircle turning cutter, 3\u00a0mm\u00a0cut-off tool, \u03a610\u00a0drill, \u03a64\u00a0end milling cutter, \u03a68\u00a0end milling cutter, \u03a612\u00a0end milling cutter, \u03a63.3\u00a0drill, M4\u00a0tap, \u03a64.5\u00a0drill, and \u03a66-45\u00b0chamfering cutter<\/span><\/p>\n<p><span style=\"font-size: 115%; color: #000000;\">1.
