Machinable Ceramics and Glass Ceramics
Glass ceramics, also known as machinable ceramics, are mica glass-ceramic with synthetic mica as the main crystal phase. They are ceramic materials that can be machined.
Features of glass ceramics:
- High strength and light weight
Glass ceramic is harder than natural stone and not easy to damage. The thickness of the material can be combined with the construction method.
- Rich and changeable colors
Glass ceramic is made by the accumulation method, without natural stone texture (broken here). The accumulation method is a method that can create rich tones.
- Excellent weather resistance and durability
The acid resistance and alkali resistance of glass ceramic are better than granite and marble. Since it is an inorganic material, even when exposed to wind, rain, and polluted air, it will not produce deterioration.
Processing:
- Turning processing:
The key to the turning operation is using a low cutting speed. The lower speed can cool the workpiece, thereby preventing the generation of small cracks on the ceramic surface. The feed speed is 0.05-0.13mm/r. Water.
- Milling:
Milling is similar to turning. It uses cemented carbide tools, with a 50-60rpm slow speed. The feed rate is 0.03-0.4mm/r, and the cutting depth is no more than 3mm. For milling planes, end faces, or spherical surfaces, it does not matter how many chip grooves there are.
- Drilling and processing of glass ceramics:
If you want to drill a larger hole, it is best to drill a small hole of about 1.5mm first. At the bottom end of the hole, drill a cone with the same size as the hole to avoid surrounding caving when drilling through. This ensures a better drilling effect. Or two sides to fight. Alternatively, make a drill die. If you want to drill larger holes with precision, it is best to follow the sequence 6, 8, 10.
4.Grinding of glass ceramics:
During non-batch processing, pay attention to cushioning with kraft paper or sandpaper when clamping to avoid overclamping and breakage. Grinding machinable ceramics is the fastest and most economical method. Especially with diamond grinding wheels, precise shape of the product can be maintained, and its service life is long. Silicon carbide or alumina grinding wheels can also be used. Welcome inquiry if you are interested in the glass ceramics.
