Macor Ceramic Machining Guide 2025

When Macor ceramic machining, the first consideration is tool selection. Although one of Macor’s advantages is that it can be machined with carbide tools in a manner similar to metal, there are still some differences. For example, when drilling the material, Macor may exhibit slight chipping at the edges, a phenomenon that generally does not occur with metals.

Macor ceramics are easier to achieve high-precision processing than other ceramics, such as (complex shapes such as ion trap brackets and quadrupole brackets)

Tool Selection

Macor Ceramic Machining recommendations for tool selection

Usually, the cutting tool can be selected by combining a diamond grinding head and an alloy milling cutter. The diamond grinding head is used for roughing, and the alloy milling cutter is used for finishing. This method can effectively improve the processing efficiency and processing quality, and reduce the processing cost of the project.

Machining equipment selection

How to choose 3-axis, 4-axis, or 5-axis for machining? How to set the spindle speed and feed rate?

Generally, we choose different machine tools according to different configurations. The spindle speed can be set between 15000-18000rpm, and the feed speed of the machine tool is 2000mm/min (note that different structures have different setting values)

Internal thread Machining

How to machine internal threads and micro holes in macor ceramics? What will happen during machining?

In theory, the internal thread of macor can be processed to M1.4, but due to the material strength problem, even if it is processed to M1.4, the practicality of its thread is not high. Therefore, we recommend that you design the internal thread to be larger than M2 for the project. Secondly, when processing threads, you need to pay attention to the chipping of the thread, which can generally be solved by adding chamfers to the thread mouth

Coolant selection

The coolant used in the machining process is usually water-soluble. Oily cutting fluids are easy to stick to the tool and are not conducive to machining.

How to control surface roughness

The machining accuracy can be improved by selecting a grinding wheel with a higher mesh number. For situations with higher surface requirements, further optimization can be achieved through polishing.

Frequently Asked Questions

Are scratches likely to occur during machining?

Due to the low hardness of the material, it is easy to scratch the ceramic during the production process, forming fine scratches. You can reduce the friction between the ceramic surface and other objects during the production process, and do a good job of packaging protection during production and transportation.

How to avoid material cracking and edge collapse

The clamping force of the product in mechanical processing should not be too large, and it can be bonded with glue or wax. The edge collapse problem can be solved by appropriately increasing the spindle speed of the machine tool and optimizing the tool and processing path.

What mounting method does Macor Ceramic Machining recommend?

Common clamping methods include vise clamping, paraffin wax, and glue. The appropriate clamping method should be selected according to the actual product situation.
