Custom 3-Inch Multi-Hole Quartz Glass Disc, 2.8 mm Thick, Precision Through-Hole Machining

Custom 3-Inch Multi-Hole Quartz Glass Disc, 2.8 mm Thick, Precision Through-Hole Machining

This multi-hole quartz glass disc is a custom-machined circular component featuring multiple through-holes arranged across the disc surface. Based on the product label shown in the photograph, the sample measures approximately 3 inches in diameter and 2.8 mm in thickness.

Each hole passes through the full thickness of the disc. The hole positions and spacing can be specified to match the requirements of an equipment assembly, fixture, or other custom component. The overall disc dimensions and hole pattern can be produced from a technical drawing or reference sample.

Quartz glass is used in a range of industrial, laboratory, optical, and semiconductor equipment. Its suitability for a particular process depends on the material grade, operating temperature, chemical environment, and required surface condition. We can review these requirements together with the drawing before confirming the manufacturing details.

Specifications

Custom Machining Options

The disc can be reviewed for customization according to the part drawing or sample. Depending on the design, the following details can be specified:

• Disc diameter and thickness
• Number and diameter of through-holes
• Hole coordinates, spacing, and pattern
• Distance between holes and the outer edge
• Surface finish and edge treatment
• Required dimensional tolerances
• Material grade and intended operating conditions

Please note that the final manufacturable dimensions and tolerances should be confirmed against the approved drawing.

Typical Applications

Depending on the equipment design and operating environment, multi-hole quartz glass discs may be used as:

• Components in semiconductor or process equipment
• Fixtures or supports in laboratory equipment
• Parts in optical or analytical instruments
• Custom equipment components requiring multiple through-openings
• Replacement parts manufactured to match an existing sample

The final application suitability should be evaluated according to the actual process conditions and assembly requirements.

What to Include in a Quote Request

To help us review your request and prepare an accurate quotation, please provide:

1. Required quantity
2. Disc diameter and thickness
3. Hole quantity and hole diameter
4. Hole positions or a hole-layout drawing
5. Surface finish, edge finish, and tolerance requirements

Frequently Asked Questions

Are the holes through-holes?
Yes. This product description refers to ordinary through-holes that pass through the full thickness of the quartz disc.

Can the hole pattern be changed?
Yes. The number, diameter, spacing, and positions of the holes can be specified according to the customer’s drawing or sample.

Are 3 inches and 2.8 mm standard dimensions?
These are the reference dimensions shown for the photographed sample. Please confirm the required dimensions for your order.

Can you manufacture the disc from a sample?
A sample can be provided for review. The final design and quotation will depend on the dimensions and machining requirements that can be confirmed from the sample or drawing.
