  This article summarizes the common problems and improvement methods of   CNC machining process from years of production process, and how to select three important factors of speed, feed rate and depth of cut in different application areas for your reference and prevention; Common problem Reason Improvements Overcutting the workpiece 1. The knives, the tool strength is not too long or too small, resulting in the tool knives. 2. The operator is not working properly. 3. The cutting allowance is uneven (for example, 0.5 on the side of the curved surface and 0.15 on the bottom) 4. Improper cutting parameters (eg too tight tolerance, SF setting too fast, etc.) 1. Principle of using a knife: It can be big or small, short or not long. 2. Add the clear angle program, and leave the balance as even as possible (the side and the bottom surface are the same). 3. Adjust the cutting parameters reasonably and round the corners at the large margin. 4. Using the machine tool SF function, the ...

  FR-4 classification: The surface colors of  FR-4 epoxy glass cloth laminate  are include: Yellow FR-4, white FR-4, black FR-4, blue FR-4, etc. FR-4 is a type of sheet and used for PCB as the substrate. According to the different of reinforcement materials, the FR4 sheets are mainly classified into the following four types: 1) FR-4: glass cloth substrate 2) FR-1, FR-2, etc.: paper substrate 3) CEM series: composite substrate 4) Special material substrate (ceramic, metal base, etc.) FR-4 is a laminate board that obtained by immersing epoxy resin with alkali-free glass fiber cloth by pressing under high-temperature and high-pressure,it’s rigid insulating laminated sheet. Features: High mechanical and dielectric properties, good heat and moisture resistance and good machinability. Uses: Insulation structural parts in motors and electrical equipment, including various types of switches FPC reinforced, electrical insulating carbon film printed circuit boards, computer drillin...

  What is insert molding process? Insert molding is the process of putting inserts before injection molding. The finished product of  insert molding  is a single plastic part  with an insert surrounded by plastic. Inserts can be made of metal or different types of plastics. Insert molding has been applied in many industries, such as insert molding couplings, thread fasteners, filters, electronic and electrical components. The most advantage of the insert molding is cost-saving. Insert molding is a highly efficient alternative to the assembly of discrete parts. It enlarges the performance of plastics and helps to reduce product costs by limiting the amount of expensive metals needed to produce products, also it reduces assembly and labor costs, and increasing design flexibility and part reliability. We are professional in  insert mold making . Sharing an insert mold made by Green Vitality used for electronic components.
