CNC 5-Axis Machining for Advanced & Technical Ceramics
Simultaneous 5-Axis · Ultrasonic-Assisted Spindle · DWO & TCPC Accuracy Control
CNC 5-axis machining moves and rotates a workpiece across five independent axes at once, which is what makes it possible to cut multiple faces and angles of a hard, brittle ceramic part in a single clamping. At LONGYI, this is the process behind our most geometrically complex work in zirconia, alumina, silicon nitride, quartz and sapphire — parts that combine tight tolerances, angled features and fine threads or bores that a 3-axis setup cannot reach without repositioning the part and losing accuracy.
Process at a Glance
One clamping instead of several is what protects the tolerance on brittle ceramic.
Every time a hard ceramic part is unclamped and repositioned, the datum can shift — and on a material with little tolerance for local stress, re-clamping itself is a risk. Simultaneous 5-axis motion lets LONGYI reach multiple faces and angled features in one setup, and an ultrasonic-assisted spindle keeps cutting forces low enough to machine zirconia, alumina, silicon nitride, quartz and sapphire without chipping the edge. Dynamic Workpiece Compensation (DWO) and Tool Center Point Control (TCPC) then keep the tool's cutting point locked to the programmed path even as the rotary axes move, so a thread as small as M1.5 or a bore as small as Ø0.4 mm machined on a tilted face lands as accurately as one machined flat. The trade-off is cycle time: ultrasonic-assisted cutting of ceramic runs slower than machining metal, and programming a 5-axis toolpath takes longer up front than a 3-axis one — this process buys precision and fewer setups, not the fastest possible cycle.
Process Capabilities
Simultaneous Multi-Axis Motion
- Simultaneous 5-axis motion for complex geometries
- Multi-angle and multi-surface machining in one setup
- Suitable for both micro-components and larger ceramic parts
Ultrasonic-Assisted Cutting
- Ultrasonic spindle for efficient machining of hard, brittle materials
- Lower cutting force reduces chipping and edge damage on ceramic
Accuracy Under Rotary Motion
- Dynamic Workpiece Compensation (DWO)
- Tool Center Point Control (TCPC)
- Holds tolerance on features machined on tilted or rotated faces
What This Buys You
- Minimized fixturing errors with single-clamp operation
- Improved surface finish and dimensional consistency
- Reduced production cost through fewer setups and less handling

Materials We Machine on 5-Axis CNC
LONGYI applies 5-axis machining to hard, brittle technical ceramics where a single clamping and ultrasonic-assisted cutting matter most.

When to Consider a Different LONGYI Process
5-axis machining is not always the most economical or most direct route to a finished part. We would rather point you to the right process up front.
If the part geometry is finalized and you need a large, repeat quantity, forming the shape close to net and machining only the critical faces is usually cheaper than cutting the full geometry from solid stock on a 5-axis machine. See Ceramic Injection Molding (CIM).
5-axis machining shapes the ceramic, but a vacuum feedthrough, brazed assembly or hermetic seal needs the ceramic bonded to a metal housing — that is a separate step. See Ceramic Metallization and Ceramic Brazing.
A 5-axis machined part is only as good as its inspection. If flatness, form or dimensional results need to be documented for your incoming inspection, see Precision Measurement.
All 5-axis work at LONGYI is produced to your drawing or sample rather than off a catalog. See how we run custom builds under OEM & ODM.
From Process to Finished Part
5-axis machining is one step in a longer manufacturing chain. Whether it is the right step for your part depends on the full process and who is running it.

Talk to Our EngineersFrequently Asked Questions
What is CNC 5-axis machining?
CNC 5-axis machining is a computer-controlled cutting process in which the workpiece and cutting tool move and rotate across five independent axes at once, instead of the three linear axes of conventional CNC — used where a part has multiple angled faces or features that would otherwise need several separate setups to reach.
What file format should I provide for complex part designs?
We recommend submitting 3D STP (STEP) files, which allow precise toolpath programming and ensure machining accuracy.
What is the maximum machining size for ceramic parts?
The maximum size we can machine is 500 mm × 500 mm × 300 mm, suitable for advanced ceramics and other hard, brittle materials.
What is the minimum thread size and hole size you can achieve?
Our CNC 5-axis machining can produce threads as small as M1.5 and holes with diameters as small as Ø0.4 mm.
Which materials can be processed with 5-axis machining?
LONGYI specializes in machining zirconia, alumina, silicon nitride, quartz, sapphire, and other advanced ceramics.
