SGRT20 4-Axis for 3D Semiconductor Profile Cutting
The SGRT20 is a high-precision 4-axis diamond wire cutting machine built for the most complex 3D cutting tasks in semiconductor and advanced ceramic manufacturing. It enhances the SGR20 platform by adding a tilting rotary axis, enabling compound-angle and multi-surface cutting in full 3D space. This makes it ideal for producing complex structures with precision surfaces, tight tolerances, and minimal material loss.

In semiconductor and advanced ceramics industries, several types of cutting equipment offer tilt-angle capability. Below is a professional comparison of four commonly used systems:
1. 5-Axis or Multi-Axis CNC Machining Centers
Control X/Y/Z plus A (rotation) and B (tilting) axes
Typically used for milling, engraving, and drilling of hard metals and plastics
Not ideal for brittle materials like ceramics or sapphire due to tool vibration
High equipment cost and large footprint
2. Multi-Axis Diamond Wire Cutting Machines (e.g. SGRT20)
Uses endless diamond wire for smooth, vibration-free cutting
Ideal for sapphire, silicon carbide, PZT, alumina, and other brittle materials
Supports programmable tilting from 0–25°, perfect for 3D contouring
High precision, minimal kerf width, and low material loss
3. Tiltable Inner Diameter (ID) Saws
Some ID saws allow minor tilt adjustment for angled cuts
Mainly used for edge chamfering or beveling in wafer processing
Limited by blade diameter and workpiece size
Less flexible for thick or nonstandard shapes
4 Laser Cutting Systems with 3D Tilt Control
Enables bevel cutting or contour shaping of thin substrates or wafers
Limited by optical path geometry and focusing system
Not suitable for thick blocks or hard brittle materials
May cause thermal damage, discoloration, or microcracks
SGRT20 Advantage
Compared to the above technologies, the SGRT20 4-axis tilting diamond wire saw is uniquely positioned for:
Multi-surface shaping of brittle materials
Compound-angle slicing without thermal damage
カッティング non-conductive, hard materials with ultra-low edge chipping
Full 3D control in a compact and cost-effective platform
If your application involves angled cuts on fragile semiconductor materials, the SGRT20 is the optimal solution for both performance and precision.
