Wholesale Customize Cnc Machining Quartz Plate Manufacturers & Supplier

Our CNC machining centers routinely achieve linear dimensional tolerances down to ±0.01 mm (±10 µm) for plate outlines, steps, cutouts, and pockets. For precision thickness, lapping and optical polishing achieve tolerances of ±0.005 mm, with parallelism below 5 arcseconds and surface flatness up to λ/10 at 632.8 nm upon request.

Quartz is an exceptionally hard, brittle material (Mohs hardness ~7). We minimize subsurface damage by using high-speed ultrasonic-assisted CNC machining stations operating with progressive diamond grit feeds, followed by precision chemical acid etching (HF buffer) to relieve edge tension. Finally, high-temperature furnace annealing at ~1150°C removes residual internal stresses.

The decision centers on your operating wavelength and thermal conditions: JGS1 is synthetic fused silica offering exceptional UV transmission from 185 nm without bubble inclusions; JGS2 is refined natural fused quartz ideal for visual spectrums (220–2500 nm); while JGS3 is synthetic infrared-grade quartz with low OH concentrations (< 5 ppm), eliminating the typical 2.73 µm absorption dip for IR viewports.

We accept standard 3D STEP (.step, .stp) and IGES (.igs) files alongside dimensioned 2D drawings in PDF, DWG, or DXF format indicating critical GD&T references, surface scratch-dig specs (e.g., MIL-PRF-13830B 20-10 or 40-20), chamfer needs, and optical coating requirements (such as AR, HR, or dielectric filters).

Standard prototype evaluations and DFM feedback are delivered within 24 business hours. Prototype quantities (1–10 pcs) are dispatched within 7–12 working days using stocked ingots. High-volume repeat batch production runs usually cycle in 3–4 weeks, supported by cleanroom protective packaging and traceable CMM inspection certificates.
