DAG811Automatic Surface Grinder

An automatic grinder that has evolved to support a wide range of needs

Φ200 mm
1 axis, 1 chuck table

Next-generation manual grinder that supports Φ8-inch workpieces

DAG811 is the next-generation model to DAG810, featuring a single-axis, single-chuck table configuration. It accommodates workpieces up to Φ8 inches (200 mm) in diameter, and supports Φ300 mm workpieces as an optional specification.

Supporting a wide range of needs

Enhanced grinding accuracy and broader material compatibility
By optimizing the processing point layout and redesigning the axis structure, the grinding accuracy stability has been further improved. Additionally, by selecting a high-power spindle as an optional specification, the equipment can handle difficult-to-process materials.
Flexible grinding methods for diverse processing needs
DAG811 supports both in-feed grinding and creep-feed grinding methods. Automatic switching between the two modes is possible as an optional specification, eliminating the need for conversion work and enhancing operational efficiency and throughput.

Enhanced operability

Incorporating DISCO’s new design concept, the operation screen size has been enlarged from 10.4 inches to 15 inches, doubling the display area for improved visibility and usability.
Furthermore, the optional motorized fine-adjustment axis allows on-screen wafer shape correction.

UI design

Improved workability

During wheel replacement, the spindle can be raised above the water case, allowing operators to perform replacement without reaching inside the case.
This simplifies maintenance and prevents contamination of cleanroom wear.

Compact design

By reducing the equipment depth by 200 mm compared to the previous model, the footprint has been reduced by approximately 12 %, making DAG811 the first DISCO grinder with a floor area of less than 1 m².
