Industrial ceramic shaft parts have high melting point and high melting point, high strength, conductors and insulators at room temperature, and ceramic shafts produced at high temperatures with excellent properties such as electrical conductivity. The manufacturing standard of industrial ceramic shaft core depends on the situation, and it must be carefully planned in advance, and a variety of manufacturing plans should be prepared in advance to compare, so as to choose the best plan. As a professional ceramic company, Pintejin can meet the following shaft parts standards:

  • Radial size can reach 0.0015mm, roundness
  • 0.001mm, concentricity 0.0025mm,
  • roughness 0.02;

In recent years, ceramic manufacturers and diamond machining units have jointly designed and manufactured a new type of diamond drilling tool (electroplated diamond drill bit). All very good. It can completely simplify the machining of holes, as long as the electroplated diamond drill bit is installed on the drilling machine, the machining can be carried out by selecting the appropriate speed, and the quality of the ceramic machining holes is high.

Hole Parts:

  • Machined minimum hole diameter of 0.2mm,
  • depth can be 3mm, hole above 1mm, radial dimen-
  • sion tolerance 0.002mm, roughness 0.02-0.04;

The higher the surface quality requirements, the higher the processing cost. In the case of meeting the requirements of use, the larger Ra value should be selected as much as possible to reduce the cost. Basically all machining methods can machine flat surfaces, turning, milling, planing, grinding, drawing and wire cutting. Among them, surface grinders are widely used. Grinding is usually used for finishing. When batches are small, planers and wire cutting are usually used.

As a professional ceramic company, Pintejin can meet the following ceramic plane machining standards:

  • Tolerance can be achieved 0.002mm, flatness
  • 0.0015mm;

When the grinding area of the workpiece is relatively large, the heat generation during step machining is large, and it is easy to deform, so you need to pay attention to the roughness, you need to choose the direction of cutting the steps, and it is better not to grind the side and bottom at the same time when finishing, and use a coarse grinding wheel to lie down. Grind one side, then stand up and grind the other side, try to avoid grinding with the side of the grinding wheel, and finally change the fine grinding wheel to clear the corner. As a professional ceramic company, Pintejin can meet the following ceramic step machining standards:

  • The stage difference accuracy can reach 0.002mm,
  • and the R angle clear root can achieve R0.02mm;

The ceramic thread machining methods are grinding machining and EDM conjugate rotary machining. Grinding has low cost, high speed and high efficiency, but it will cause damage to individual thread surfaces during the machining process, thus affecting the quality and accuracy of the thread. Therefore, EDM conjugate rotary machining is the best method for machining ultra-high temperature ceramic threads.As a professional ceramic company, Pintejin can meet the following ceramic thread machining standards:

  • It can process internal thread of M2 or above,
  • thread precision GB- 7H; external thread size is not
  • limited, thread precision GB-6g;
