Processes

Chinese precision manufacturing workshop with CNC machining centers
A production environment built around machining, process control and verification.

01 / ADVANCED CERAMICS

Process control for hard, brittle and high-performance ceramics.

We machine alumina, zirconia, silicon nitride, silicon carbide, aluminum nitride, boron nitride and machinable glass ceramics into shafts, plungers, sleeves, rings, plates, substrates, tubes, nozzles, valves, pump parts and complex profiles.

Ceramic CNC machining and precision finishing
01

Near-net-shape forming

Cold isostatic pressing, injection molding, dry pressing, extrusion, tape casting and ceramic additive manufacturing establish the main geometry before firing.

成形 → 烧结 → 精加工
02

Green machining

Turning, milling, drilling, slotting and multi-axis machining are completed before firing, with shrinkage compensation built into the process plan.

生坯加工 → 烧结 → 尺寸修正
03

Sintering & densification

Atmosphere, pressure, temperature and cycle control improve density, grain structure and consistency for demanding ceramic components.

烧结 → 致密化 → 性能确认
04

Diamond precision grinding

Surface, ID, OD, profile and double-disc grinding establish size, roundness, concentricity, flatness and surface quality.

05

Ultrasonic-assisted machining

Rotary ultrasonic drilling and grinding reduce machining force and help limit edge chipping and subsurface damage in hard, brittle ceramics.

Lapping & polishing

Single- and double-side lapping, precision polishing and CMP refine sealing faces, datum surfaces and high-finish component areas.

平面度 · 平行度 · 粗糙度
07

Ultrashort-pulse laser processing

Picosecond and femtosecond laser processes create microholes, narrow slots and fine structures with a minimal heat-affected zone.

Machinable ceramic CNC

BN and machinable glass ceramics can be turned, milled, drilled and machined in multiple axes for insulated and high-temperature components.

CORE CAPABILITY

Diamond grinding, ultrasonic machining and surface finishing work as one chain.

For fired ceramic components, precision grinding establishes dimensional and geometric control; ultrasonic and laser processes extend the process window for microholes, thin walls and difficult contours; lapping and polishing refine critical surfaces.

MANUFACTURING → INSPECTION → DELIVERY

A manufacturing route is designed around the final function of the part.

We combine near-net-shape forming, sintering, multi-axis machining, turn-mill, diamond grinding, precision grinding, ultrasonic and laser processing, EDM and precision inspection to support prototypes through repeat production.
