Customer case-PCD micro drilling processing of zirconia ceramics

22 October 2023

Recently we received an inquiry from a customer from Spain who needs PCD micro drilling to process zirconia ceramics.

Zirconia ceramic

Zirconia ceramic is a high-hardness precision ceramic material with a hardness of over HV1250.

Features:

Excellent thermal insulation; good wear resistance; good surface finish; high fracture toughness;

Application:

Pump parts; molds; cutting tools; cutting blades; communication hardware...

Zirconia ceramic parameters
Performance		Parameter
Densities	g/cm³	6
Mohs hardness	Level	8.5-9
Mild bending resistance	Mpa	1100
Compressive strength	Mpa	2500
Fracture toughness	Mpa.M-3/2	11
Modulus of elasticity	Gpa	200
Thermal expansion coefficient	X10-6/°C	10.5
Thermal shock resistance	∆T℃	300
Temperature	℃	500-1000

Difficulties in precision ceramic hole processing:

It is required that the material has no obvious cracks after drilling;

The hole wall has high requirements for smoothness, no burrs and no chipping;

The dimensional accuracy requirements are high, and the minimum hole diameter is only 0.1mm.

PCD micro drill

Features:

PCD micro-drills have high hardness, are wear-resistant, and have a relatively longer service life than traditional alloy micro-drills;

PCD micro drill products are widely used and can process non-ferrous metals and inorganic non-metallic materials with high processing accuracy;

PCD micro drills produce better hole wall quality than traditional alloy micro drills.

Applications: semiconductors; national defense; aerospace; chips, communication electronics; automotive electronics; high-end medical equipment;
