class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Although PEEK is a difficult-to-machine material among engineering plastics, it is easier to cut than metals.<\/p>\n\n\n\n<p>This section describes the various benefits of cutting PEEK.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">High-precision, high-quality finishing is possible<\/h3>\n\n\n\n<p>Cutting allows machining with high precision in both dimensions and surface roughness because there are no thickness restrictions on the material as long as the machine can handle it.<\/p>\n\n\n\n<p>This makes PEEK suitable for processing in fields that require micron-level precision, such as semiconductor devices, medical equipment, and electronic components.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Fast delivery and low-cost production<\/h3>\n\n\n\n<p>Cutting does not require the fabrication of dies, which is necessary for casting and forging processes.<\/p>\n\n\n\n<p>There is no need for the time and costs incurred in mold fabrication, and fabrication can be done immediately with 3D-CAD data.<\/p>\n\n\n\n<p>In particular, we can provide fast turnaround and low-cost production for small-lot production of PEEK-based products and prototypes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">High flexibility in processing<\/h3>\n\n\n\n<p>In addition to having no restrictions on material thickness, cutting is characterized by a high degree of machining flexibility due to the availability of various machining tools such as \"5-axis milling machines\" and \"multi-axis (multitasking) machines.<\/p>\n\n\n\n<p>In addition to the top surface, the machine can process PEEK from the front\/back and right\/left sides, enabling PEEK to be processed into more complex shapes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"PEEK%E5%88%87%E5%89%8A%E5%8A%A0%E5%B7%A5%E3%81%AE%E3%83%87%E3%83%A1%E3%83%AA%E3%83%83%E3%83%88\"><\/span>Disadvantages of PEEK cutting process<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>While cutting PEEK has its advantages, it also has its disadvantages.<\/p>\n\n\n\n<p>This section describes the disadvantages of cutting PEEK that you should keep in mind.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cost is higher for mass production.<\/h3>\n\n\n\n<p>The disadvantage of cutting is that it is more expensive for mass production.<\/p>\n\n\n\n<p>Cutting process produces chips, which are wasted material, because the process is carried out while cutting the material.<\/p>\n\n\n\n<p>Chips can be difficult to reuse, and if the material itself is expensive, the cost is likely to be high.<\/p>\n\n\n\n<p>In addition, the greater the amount of cutting, the longer it takes to process, which further reduces production efficiency when complex shapes or high precision is required.<\/p>\n\n\n\n<p>Although the time and costs incurred in mold fabrication are unnecessary, it is important to remember that the processing method using molds is often more cost-effective for mass production.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Workmanship is easily influenced by the skill of the processing engineer.<\/h3>\n\n\n\n<p>Cutting PEEK requires a variety of skills, including knowledge of tool selection and processing techniques to produce high-precision products.<\/p>\n\n\n\n<figure

process, the skill of the operator can easily affect the workmanship.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">It's hard to keep making the same thing.<\/h3>\n\n\n\n<p>Continuous cutting operations will cause wear on the cutting tools used, which will affect dimensions, surface roughness, etc.<\/p>\n\n\n\n<p>Note that each machined part needs to be controlled in order to make the same thing by cutting with PEEK.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\"

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>This section describes points to note when cutting PEEK.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Know-how is required to adjust cutting conditions<\/h3>\n\n\n\n<p>Due to the high hardness of PEEK, cutting tools may wear or chip if appropriate cutting conditions are not set during cutting.<\/p>\n\n\n\n<figure

alt=\"Machining\"\/><\/figure>\n\n\n\n<p>If the blade is selected incorrectly, the blade itself may break.<\/p>\n\n\n\n<p>Since adjusting cutting conditions and infeed methods requires know-how, it is important to request processing by a contractor with sufficient knowledge and skills.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">In some cases, prior heat treatment is necessary to prevent distortion.<\/h3>\n\n\n\n<p>Depending on the shape of the item to be cut, the heat generated during the cutting process may cause distortion.<\/p>\n\n\n\n<p>When cutting thin-walled parts and other distortion-prone shapes, heat treatment must be performed in advance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Appropriate cutting tools must be selected.<\/h3>\n\n\n\n<p>Because PEEK is an extremely hard material, the tools used in cutting tools are subject to severe wear, a characteristic that tends to shorten tool life.<\/p>\n\n\n\n<p>It is important to select tools that can cut PEEK stably, such as carbide cutting tools or tools with coatings that have high hardness.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\"
