Precision CNC Machined Parts

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.

Precision CNC Machined Parts Benefits

SCHOTT Advanced Optics has accumulated many years of experience in the production of precision CNC machined 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

Precision CNC Machined Parts Materials

Precision CNC machining can be applied to all types of optical and color glass, as well as ceramics. Some commonly processed materials include:

Borosilicate glass
Filter glass
Optical glass
Technical glass
ZERODUR^® glass ceramic

Precision CNC Machined Parts Forms of Supply

CNC machined parts can be supplied in dimensions up to 2550 x 700 x 500 mm or 1000 x 1000 x 1000 mm.

Precision CNC Machined Parts Specifications

We can produce machined blanks in line with our customers' specifications and ISO 10110 specifications.
