Product Description

Product Description

Easy Processing White Machinable Glass Ceramic Part Macor Washer Mgc Piece

These curved-special shaped multi-hole machinable glass ceramic parts feature pure white compact texture and several positioning through-holes on the curved outline. They work as insulating brackets for high temperature clamps, gripper gaskets, instrument locating plates and heat isolated fixture connectors.

Machinable Glass Ceramic Part

The high performance machinable glass ceramic features zero water absorption rate and low apparent porosity. Its moderate hardness supports CNC profile milling, hole drilling, edge trimming and chamfering. Irregular outlines and varied hole layouts are customizable with no high cost mould. With dependable mechanical strength, heat resistance and insulating property, the parts are widely applied in heating fixtures, precision testing machines, semiconductor jigs and automated equipment assemblies.

Physical feature. Mohs hardness ranges 4 to 5. Contours and holes keep smooth edges after machining with little edge chipping. The density is 2.6g/cm³ with waterproof dense texture.
Thermal resistance. The average thermal expansion coefficient equals 72×10^-7/℃ from minus 50℃ to 200℃ for excellent thermal shock resistance. 
Mechanical property. Flexural strength exceeds 108MPa and compression strength exceeds 508MPa to endure bolt fastening, structural pressing and machine vibration loads.
Electrical insulation. The permittivity ranges 6 to 7 alongside low dielectric loss for stable high temperature insulation.

Macor Washer Mgc Piece Main Advantages

Easy CNC machining for curved profiles, counterbores and stepped surfaces. Small batch samples keep acceptable expense.
Stable heat resistant and insulating capacity to block heat and electric conduction between mechanical components.
Non-absorbent dense material prevents damp ageing and adapts to dusty and humid working surroundings.
Drawing-based customization covers outer profile, hole dimension, hole layout and workpiece thickness. Raw blanks and finished machined workpieces are both provided.

Please share your engineering drawing, hole specification and operating-temperature information so we can arrange suitable CNC processing.

Q1: Can special outline and hole positions be customized 
A: Part contour, hole diameter, hole quantity and layout are machined according to your drawing.

Q2: What is the safe long time working temperature 
A: Safe continuous working temperature stays under 800℃ and short time higher temperature exposure is permitted.
