High Difficulty machining

  • Thin-wall machining
    We can successfully perform challenging thin-wall machining work by optimizing jigs and machining methods.
  • 3D machining
    We prepare a 3D model based on drawings and write programs to manufacture the desired product. Upon request, we are also able to measure an actual product and produce items based on the actual dimensions.
  • Special internal-diameter machining
    We can perform special, internal-diameter machining work to make monolithic items without cutting the workpiece into sections.

Other machinings

  • Fabrication of larger parts
    Large rings, tubes, chimneys, susceptors and retorts are being fabricated from smaller parts. This unique staved design eliminates the need for large diameter feeder stock which often has long lead times.
  • Sectional machining
    We can perform sophisticated machining tasks such as ensuring that there are no gaps (no light leakage) between mating surfaces, as required in sectioned products used in compressor piston rings and similar applications.
  • Porous materials
    We are able to precision-machine very demanding porous items quickly.

Inspection & Quality Control

XRD Graphite is certified by ISO9001:2015, Our graphite products are tested in accordance with international, national and industrial standards. The equipment has a three coordinate measuring instrument with precision of up to 0.02mm, bending resistance, compression resistance, and Shaoshi hardness testing instruments.
The company actively constructs the enterprise quality management system, and carries out the perfect quality inspection. It has four functions: gatekeeping, prevention, reporting and improvement. Commonly used testing standards are as follows:

  • Size check: according to customer drawing requirements or national standard tolerance value table.
  • Shore hardness test.
  • Flexural strength test.
  • Quantity.
  • Packing.
  • Weight.
  • Assembly.
