CNC Machining Processes for Ceramics
CNC milling involves a manufacturing process with a highly customizable automated mode. More than carrying out the same operation as drilling or cutting, CNC Milling machines can conduct each of them at almost any angle. They can be oriented either horizontally or vertically according to the properties of the target material together with the nature of the cutting operations. The desired ceramic parts are created by consistently removing extra materials from the workpiece, which depends on the computerized controls and specialized cutting tools.
A CNC milling machine conducts the milling process through the four production steps similar to other machining models.
- A CAD model for the product
- A conversion from the CAD model to a CNC program
- Setup of the CNC milling machine for production
- Execution of the milling operation
Core drilling refers to a process that removes a cylindrical core from the drill hole. A core drill consists of three main parts:
- Bits or drill bits
The drill bits are usually coated with different objects relying on their different usages. For instance, core drills with a diamond-coated drill bit are normally used for cutting concrete on big construction projects, whereas a carbide-coated bit is often found in a masonry core drill. Core drilling makes it possible for both the formation of a hole and the clean removal and analysis of a core of the ceramics.
Characteristics of Ceramics
There are large quantities of remarkable properties that ceramics possess. Certainly, it’s worthwhile to recognize its several shortcomings.

Technical Ceramic Materials for CNC Machining
Aluminum Nitride (AlN)
Aluminum Nitride (AlN) ceramic is a hybrid type of ceramic known for its high mechanical strength and great thermal conductivity.
Boron Nitride (BN)
Boron Nitride (BN) ceramic is an advanced synthetic ceramic material available in two forms: solid and powder. Different from other traditional ceramic materials, BN has incredible thermal conductivity.
Silicon Nitride ceramic is one of the most widely used of all technical ceramic materials. It has an excellent combination of thermal, mechanical, and electrical properties.
Zirconia outperforms traditional ceramics that are brittle and hard with their excellent strength, wear resistance, and flexibility.
Quartz has great chemical, thermal, and optical properties and is often used in lighting and semi-conductor fields. This is best done with grinding, diamond tools, or water jets. Abrasive techniques are far more useful than any cutting technique.
Our Tolerances for CNC Ceramic Machining
The extreme tolerance can be realized once the size, geometry, and shape of ceramic parts are determined. We continuously strive to be a trustable supplier who can provide our customers with custom CNC machining parts of the highest quality and tight tolerance as per their specifications. Our advanced measuring equipment and highly skilled QC inspectors lay a sound guarantee for each product in the whole manufacturing process.
Tips for Designing and CNC Machining Ceramics
You are supposed to keep in mind some specific inherent characteristics that ceramics possess when starting product design. Ceramics are so brittle that they can crack easily. Thus, it's greatly vital to keep stress from focusing on just a single point. Several tips below may be useful for your CNC machining of ceramics:

Applications of CNC Machined Ceramics
CNC machined ceramics are popular among a wide variety of industries owing to their excellent hardness and durability properties. Particularly
these three industries are preferable to apply ceramics made by CNC machining.
Ceramic CNC machining is feasible for electrical applications that require parts with extreme complexity and wear resistance. It is greatly suited for protection against electrical hazards as its electrical insulating characteristics.
CNC machined ceramic parts also have a significant impact when there are demands on high precision and intricate industrial components. Because of the high wear resistance of ceramics, it even makes it a better choice for durability purposes.
Lots of ceramic micro-parts produced via CNC machining are used in health and care. Typical products like bioceramics are employed as implants in the body without incurring any type of adverse reaction. Another representative ceramic such as zirconia is an ideal implant in dental applications due to its high wear resistance.

FAQs of Ceramic CNC Machining
Ceramics are fragile due to their chemical bonds. Ionic and covalent bonds that chemically bond atoms of ceramics are stable ones bonded only in specific directions.
If ceramics have ever been sintered into a hardened status, it would be a big challenge in the CNC machining process because the chunks or debris would fly everywhere. Therefore, the most effective method of CNC machining for ceramics is either in the non-sintered (“green”) compact state or in the presintered (“bisque”) form.
In the presintered state, machining processes such as CNC milling, turning, and grilling are all feasible for handling ceramic parts. In the bisque state, the material removal required (MRR) achievable by the machine tool can be comparable to that of tool steel and die steel.
Grinding is generally applied to process ceramics in their sintered state. A polished surface finish can be realized with the help of the abrasive wheel. It is also preferable to use a fluid coolant to lubricate the area being ground for grinding ceramics. It is better to use resin-bonded wheels that press synthetic or natural diamonds of different particle sizes in polymer resin at different concentrations for sintered ceramics.
