  • Q I am designing a new product that requires CNC machining to create a prototype and final product. How do I select the most suitable material for CNC machining for my project?

    A At JST Industry, we understand that choosing the right CNC machining material is critical to product design. You should first consider the scenario in which your product will be used, including the required mechanical properties, temperature resistance, corrosion resistance, and cost-effectiveness. We offer a wide range of material options including, but not limited to, aluminum alloys, stainless steel, brass, various alloys, and many plastics. Our team of experts can assist you by selecting the most appropriate material for your specific needs and provide expert design optimization advice to ensure an efficient and cost-effective CNC machining process.
  • Q I would like to know how the selection of different materials in CNC machining process affects the final machining cost?

    A At JST Industry, we recognize that material selection has a significant impact on CNC machining costs. The type of material, difficulty of machining, and market availability all affect its price. For example, steel is widely used due to its lower cost, while titanium alloys and certain advanced alloys are more expensive due to their higher material cost and machining difficulty. In addition, the machinability of the material also affects the cost, e.g. aluminum alloys are usually less expensive due to their ease of machining. Our quoting system takes all of these factors into account to ensure you get the most accurate cost estimate.
  • Q What are some design practices that can help me reduce machining costs when designing CNC machined parts?

    JST Industry, with years of industry experience, offers the following design optimization suggestions to reduce CNC machining costs:
    Consider non-functional internal right angles in the design and change them to R angles to reduce clearance costs.
    Reduce the number of bone positions on the part to minimize machining time and complexity.
    Increase wall thickness where appropriate to minimize the risk of deformation of the part during machining.
    Use standard hole sizes and threads whenever possible to simplify the machining process.
    Work with our engineers to select economically sound material and finish options.
    Mark only the tolerances that are necessary and most important to the design to avoid unnecessary accuracy requirements.
  • Q I have stringent requirements for accuracy in my products, what tolerances can be achieved with CNC machining and how does this affect the quality of the final product?

    A At JST Industry, our CNC machining services are capable of meeting extremely high tolerances, often to ±0.01mm, thanks to our advanced machining equipment and strict quality control processes. This high-precision machining capability ensures consistency and reliability of parts, which is especially important for assemblies that require high-precision fit. Our quality assurance system includes multiple inspections and calibrations to ensure that each part conforms to the customer's design drawings and tolerances, thus guaranteeing the quality of the final product.
  • Q I am concerned that the surface of a CNC machined part may have burrs or be uneven. How can I ensure that the surface of the machined part is of the desired quality?

    JST Industry utilizes a range of advanced machining technologies and stringent post-processing procedures to ensure the surface quality of CNC machined parts. Our operators perform careful deburring after
    machining, including hand trimming and machine finishing, to ensure that all parts have a smooth, angular-free surface. In addition, we use precision measuring tools to check the dimensions of the parts several times to ensure that the dimensional accuracy meets the tolerance requirements. Depending on the needs of our customers, we also offer a variety of surface treatment services, such as anodizing, plating, powder coating and painting, to further enhance the appearance quality and corrosion resistance of the parts. Through these measures, we are ble to ensure that the surface quality of each part meets or exceeds our customers' expectations.
