Jig grinding is a specialized machining process used to create extremely accurate holes, contours, and surface profiles in hard materials. Unlike traditional grinding methods, jig grinding provides precise location control and ultra-tight tolerances—ideal for features like bores, slots, and complex contours that must be both dimensionally accurate and repeatable.
At Die Technology, jig grinding is more than a capability—it’s a legacy. Since acquiring Custom Jig Grinding in 2014, we’ve carried forward decades of experience and invested in advanced CNC jig grinding equipment to meet the evolving needs of aerospace, medical, and high-tech industrial clients. Whether it’s grinding precision gauges or multi-feature plates, our reputation is built on technical excellence, control, and consistency.
Jig grinding is a high-precision grinding process used to produce accurate holes, contours, and features in hardened or difficult-to-machine materials. The process relies on a specialized jig grinder equipped with a high-speed spindle, allowing for controlled movement of the grinding wheel along predefined paths. Unlike surface grinding or ID/OD grinding, jig grinding offers exceptional true-position accuracy—typically within 0.0001″—and is ideal for features that must align perfectly with other dimensions on a part.
To visualize it, think of jig grinding like using a fine-tipped engraving tool guided by a coordinate system. It removes material slowly but with extreme accuracy, making it essential for components where even the slightest deviation can compromise function or fit.
In modern manufacturing, jig grinding ensures part integrity in tight-tolerance assemblies, tooling inserts, or mission-critical components. It’s especially valuable when paired with EDM or milling operations as part of a multi-process machining strategy.
Die Technology’s precision jig grinding operations are powered by CNC-controlled grinders capable of achieving:
With in-house CMM services and custom fixturing, we ensure high repeatability and minimal deviation—even across complex multi-feature plates.
Our jig grinding services are often integrated with wire EDM, sinker EDM, or milling processes as part of complete die, fixture, or tooling builds. We support:
We combine technical excellence with modern automation to deliver speed, precision, and reliability—even for your most complex challenges.
With the combined expertise of Custom Jig Grinding and Die Technology, we bring unmatched capabilities, tight process control, and technical expertise. Clients trust us when ultra-precision and consistency aren’t optional—they’re essential. From one-off prototypes to production-ready tooling, we deliver precision you can build on.
