Precision CNC Machined Parts
Product Information
|
CNC machined parts are parts which have been processed to complex forms. These parts have a matte (non-transparent) finish, as they have been processed with diamond tools. The process involved typically uses 3- or 5- axis machines, coupled with the use of CAO software, nearly all-geometrical forms can be achieved.
Benefits
SCHOTT Advanced Optics has accumulated many years of experience in the production of blanks and has a variety of CNC machines available.
In addition, we can:
- Produce prototypes as well as ramp up to serial production
- Supply precision blanks instead of raw glass, saving our customers the investment and administration efforts involved with raw glass stock
- Reduce inner stress caused by diamond machining by chemical (acid etching) or thermal treatment (tempering).
|
Key Applications
|
Precision CNC machined blanks are often put to optical and mechanical uses in applications such as:
- Photolithography
- Avionics
- Medical
- Astronomy
- Metrology
|
Materials Used
|
All types of optical and color glass, as well as ceramics can be machined. Some commonly processed materials include:
- Borosilicate glass
- Calcium fluoride crystals
- Filter glass
- Fused silica LITHOSIL®
- Optical glass
- Technical glass
- ZERODUR® glass ceramic
|
Forms of Supply
|
Machined blanks can be supplied in dimensions up to 2550 x 700 x 500 mm or 1000 x 1000 x 1000 mm.
|
Specifications
|
We can produce machined blanks in line with our customers' specifications and ISO 10110 specifications.
- General dimensional tolerances: up to 0.010 mm
- Surface roughness: G3 (up to 0.4 µm Rq)
- Flatness: 0.005 mm / 100 mm
- Small holes up to 0.5 mm diameter

Quality Assurance
|
Our quality control is based on self-checking during production, random inspection, and a 100% final inspection. Equipment we use include: 3D optical measurement (Smart Scope), 3D measurement machines, profile projector as well as surface profiling (Talysurf). Complex forms are also measured with Form Talysurf. Inspection reports are available upon request.
