Ultra-Precision CNC Machine for Nip Optical Mold Inserts

The SGDT350 features a large machining envelope, capable of handling workpieces up to 650mmmm in diameter and 300 mm in length, making it ideal for large aerospace reflectors or precision molds.

Standard configurations excel at cutting soft metals like aluminum and copper. Single-crystal silicon and germanium require application review. With optional ultrasonic or laser assistance modules, it can also process steel and hard, brittle ceramics.

It depends on your workpiece weight and process. The Aerostatic spindle offers high speed (10,000 r/min) and ultimate precision (< 30 nm runout) for parts under 50 kg. The Hydrostatic spindle provides higher load capacity (120 kg) and stiffness for heavy, large-aperture parts (max 1500 r/min).

Based on a high-purity aluminum convex sphere test case, the machine achieves a form error of PV <= 0.2 um and surface roughness of Ra <= 3.0 nm (actual results may vary depending on material, workholding, and process).

Yes. The SGDT350 combines X and Z linear axes with a C rotary axis. Furthermore, optional modules like Fast Tool Servo (FTS) and high-speed milling can be integrated to handle highly complex freeform geometries and micro-structures.
