CNC Machined Aluminum Robot Gripper Jaws
These are custom gripper jaws, fingers and nests CNC machined for pneumatic, electric and robotic grippers. Jaws are milled from 6061 or 7075 aluminum to match the workpiece contour, with mounting patterns that fit your gripper model. Lead time typically runs 3–15 working days. They suit automation integrators and end users needing reliable part handling on assembly, machining and packaging lines.

Manufacturing
How we make this part
Process, material options and inspection for cnc machined aluminum robot gripper jaws.
Jaw design starts from the gripped part: we mill a contoured nest or V-groove that matches its shape so the part self-centers when the jaws close. The mounting interface is machined to the gripper's dowel and screw pattern so jaws swap without adjustment. Weight-relief pockets keep inertia low on fast robots. Matched jaw pairs are machined together where symmetry is critical.
6061-T6 aluminum keeps jaws light; 7075-T6 or hard anodizing adds wear resistance for high-cycle applications. Where parts must not be marked, jaws can carry pads of POM, polyurethane or PEEK machined to fit. Stainless steel jaws suit food or washdown cells. Fast-wearing contact areas can be designed as replaceable inserts to cut maintenance time.
Jaw nests are checked against the workpiece model on CMM, and mounting holes against the gripper pattern. Sample parts can be test-fitted if you send them. Critical dimensions are 100% inspected before shipment, and jaw sets are labeled by station. Typical uses include CNC machine tending, pick-and-place assembly, injection-mold unloading, palletizing and lab-automation handling.
FAQ
Frequently asked questions
What do you need to design gripper jaws?
Send the gripper model, the workpiece CAD or a sample, the gripping direction and any surfaces that must not be marked. With those, we can design jaws, send a model for approval and machine them. If you already have a jaw design, a STEP file is enough.
How do I stop jaws from marking delicate parts?
Use contact pads in softer materials such as POM, polyurethane or PEEK, machined to the part contour and bolted to aluminum jaw bodies. Pads can be replaced when worn. Smooth polished nests or rubber-lined fingers are other options.
How do I get a quote for cnc machined aluminum robot gripper jaws?
Send a 3D model (STEP or IGES) and a 2D drawing with tolerances, material, finish and quantity through the quote form or by email. An engineer replies within 24 hours on business days with price, lead time and any DFM suggestions.
