Our "Drawing-Based Customization"' Process for Ceramic Components
Ceramic machining requires specialized equipment and expertise- our workflow ensuresyour drawing' s specifications are translated into high-precision, defect-free parts:
Step 1: Drawing Submission & Engineering Review
Acceptable Formats: 2D (OWG/DXF/PDF with dimensional annotations, tolerance grades, and surface finishspecs) |3D (STEP/IGES/STL for complex geometries | ike undercuts or curved surfaces).
Engineering Consultation:
Material selection: Recommend alumina/zirconia/silicon nitride based on your application (e. g.,zirconia for medical, Si3N4 for high heat).
DFM (Design for Manufacturabi lity) optimization:
Adjust walI thickness (minimum 0. 5mm for alumina, 1mm for Si3N4) to avoid sinter ing cracks.Add fi Ilets (radius 0.2mm) to reduce stress concentrations.Modify complex features (e. g., deep holes) for machining feasibility.
Quote Del ivery: Technical quote (including material cost, machining time, and lead time) within 24 hours.
Step 2: Ceramic Green Body Preparation
Forming Methods:
Isostatic Pressing: For complex shapes or large parts (max size 500mm X500mm)uses uniform pressure(200 -300 MPa) to create dense green bodies.
Injection Molding: For small, high-volume parts (e.g., ceramic gears, pins)achieves near-net shape
to reduce machining time.
Dry Pressing: For simple shapes (plates, rods)cost-effective for low-to-medium volumes.Green Body Inspection: Dimensional check (0. 5mm tolerance) and dens ity measurement (50% theoreticaldensity) to ensure sinter ing success.
Step 3:Sintering
Control led Atmosphere Sinter ing:
Alumina/Zirconia: Sintered at 1600-1700C in air (5-10 hours) to achieve 98% density.
Silicon Nitride: Sintered at 1700-1800 C in nitrogen atmosphere (8 -12 hours) + HIP treatment(1800C, 150MPa) for 99% density.
Shrinkage Control: Precisely calculate shrinkage (15 -25% depending on material) to ensure finaldimensions match your drawing.
Step 4: Precision Machining
Ceramics are hard and brittle-we use diamond tools and CNC machining centersfor high-precision processing:
CNC Grinding: For flatness (≤0. 001mm/m), parallelism (≤0. 002mm), and surfacefinish (Ra 0.02pm).
CNC Turning: For cylindrical parts (rods, tubes)-achieves diameter toleranceIT5 (±0.003mm) and concentricity ≤0.002mm.
Wire EDM: For complex shapes (gears, slots) with tight tolerances-cutsceramic parts with accuracy ±0. 005mm.
Laser Machining: For micro-features (holes ≤0. 1mm, grooves ±0.05mm)idealfor electronic or medical components.
Step 5: Quality Inspection & Surface Treatment

Optical Profilometer: Measures surface roughness (Ra) and flatness.
Material Testing:
Hardness Test (Vickers hardness tester): Confirms HV values (e. g., ≥1200 HV for alumina).
Density Test (Archimedes method): Ensures ≥98% theoretical density.
Thermal Shock Test: For high-temperature parts e. g., Si3N4)一verifies resistance to T800C.
Surface Treatment:

Step 6: Delivery & After-Sales Support
Packaging: Anti-static foam + vacuum-sealed bags + rigid boxes (prevents chipping duringshipping).
