CNC Jig Grinders

CNC grinding is a computer-controlled machining process where a grinding wheel removes material from a workpiece with high precision. CNC controls automate axis movement, spindle speed, and depth of cut, allowing for repeatable, complex geometries. In jig grinding, CNC integration enables programmable operations across multiple axes, significantly reducing setup time and human error while achieving micron-level surface accuracy.

Jig grinding uses high-speed grinding spindles with small-diameter abrasive wheels mounted on a precision CNC machine. The Roku-Roku Android II, for example, uses an HSK-E25 spindle capable of 60,000 RPM. These high-speed spindles allow for fine material removal with exceptional accuracy, making them suitable for hardened steel molds, dies, and precision aerospace components requiring tight tolerances.

The Roku-Roku Android II CNC jig grinder achieves an actual machining accuracy of ±1 micron. This is made possible through a linear motor drive system on all axes, Z-axis thermal growth compensation with 16 thermal sensors, and an active Heat Isolation System — ensuring dimensional consistency even during extended machining runs in demanding production environments.

CNC jig grinding is widely used in mold and die making, aerospace, micro machining, and precision tooling industries. Any sector requiring extremely tight dimensional tolerances on hardened components — such as injection mold cavities, aerospace structural parts, or micro-mechanical components — benefits significantly from the accuracy and repeatability that CNC jig grinders provide.

The Roku-Roku Android II is equipped with a Fanuc 31i-B5 CNC control system. This advanced controller supports the machine's full range of capabilities including linear motor drive on X, Y, and Z axes, 60,000 RPM spindle operation, thermal compensation, and the integrated jig grinding option — making it a versatile and reliable platform for ultra-precision machining operations.
