Donlee Precision possesses the sophisticated equipment required to manufacture complex precision-machined products. These include:

• computer numerically controlled (CNC) lathes,
• 3, 4, and 5 axis machining centers,
• CNC grinders, specialized contour boring equipment, deep hole drilling and honing machines, plus
• spline shaping, hobbing, and grinding equipment.

Our CBN spline grinder can hold approximately 10 feet between centers, and is able to grind all types of splines.

Our inspection department includes coordinate measuring machines and CNC gear inspection equipment.

These sophisticated and extensive machining centers, together with the highly-skilled workforce, enable Donlee Precision to develop the manufacturing processes required by the complex products they produce.
