We machine flange adapters, custom gripper fingers, joint housings and locating fixtures for robot builders and automation integrators. We work from the selected robot, gripper and workpiece interfaces to manufacture the mechanical parts defined by your equipment drawings.
Our scope is the custom mechanical component between your selected equipment and the task it performs. The six part families cover wrist tooling, mechanism development and workpiece location.
Adapters join a robot wrist to a gripper, sensor or tool mounting face. We machine each side’s bolt pattern, locating feature and angular reference, with the plate thickness and offset defined in the assembly design.

Fingers and replaceable tips connect the selected gripper to the workpiece. We machine the gripper-side mounting features and the specified steps, pockets or contact faces at the gripping end.

Empty housings and support blocks locate bearings, shafts and covers in a robot mechanism. Bearing seats, axial shoulders and connected mounting faces follow the OEM’s component and assembly drawings.
Discuss this component
Nests and locating blocks receive the part during loading, assembly or inspection. Their contacts support the defined workpiece surfaces while leaving room for the gripper to open and withdraw.

Brackets place a sensor or vision device relative to the tool or fixture. We machine the mounting face, adjustment features and device pattern without obstructing the required view or connector access.

Sleeves, stepped bushings and spacers establish the radial or axial position of adjoining parts. Their working bores, pilots and seating faces are specified together rather than by outside size alone.
Discuss this componentAn adapter locates a tool on the wrist. A finger contacts the workpiece. A mechanism housing locates the moving components. We keep those manufacturing references explicit instead of treating every robotic part as a mounting plate.
We machine an adapter from the robot-side and tool-side interface drawings. Hole count, locating geometry and angular orientation are defined on both sides; a shared flange diameter is not enough to establish the connection.
The model includes the required access for mounting screws and the route for the tool’s cables or hoses.
Locating features establish position while the fasteners secure the joint. The mating definition determines the appropriate fit and clearance.
The planned tightening sequence must remain accessible once the tool is on the adapter.
We machine the finger contact geometry from the intended gripping surfaces. The shape can provide relief around fragile edges or recesses while retaining the contact regions specified by the gripper designer.
The receiving nest and fingers need compatible access. The nest supports the part at placement; the fingers then open and withdraw without catching a locating wall or dragging across a finished surface.
The workpiece drawing identifies where the fingers may touch and which finished, thin or sensitive surfaces remain clear.
The fixture layout includes the opening and withdrawal path, not only the workpiece’s final seated outline.
We machine housings and support details to the chosen bearing and shaft arrangement. Connected bores and axial seats share the drawing’s datum system so that separate setups do not create unrelated locations.
A sensor bracket references the feature it observes. Adjustment slots provide the intended setting range, while the final fastening arrangement holds the selected mechanical position for the OEM’s calibration process.
Bore location, shoulder position and cover clearance follow the selected assembly; the bearing designation alone does not define the housing.
The mounting datum and field-of-view clearance are defined before an adjustment slot is added.
We identify what each development delivery is intended to establish, then retain the accepted geometry for repeat machining.
Prototype adapters and fingers check the selected equipment connection, screw access and workpiece clearance before the assembly enters a cell trial.
The intended material and finish are used for the integrator’s gripping, movement and handoff evaluation. Each part revision remains identifiable when observations lead to a design change.
Repeat parts follow the approved interface and contact definition. Replacing a gripper model or changing the workpiece profile is handled as a new configuration wherever the mating geometry changes.
Tool mass, part contact and stock strength lead to different material choices. We use the specified grade and condition; these references help distinguish structural aluminum, stainless locating details and polymer contact parts.

The machining plan follows the component’s working references. An adapter pattern, finger profile and housing bore require different workholding and checks.
Milling produces mounting patterns, contact pockets and relief features. We keep the finger mount and gripping profile in the same datum definition so the finished contact position is traceable to its mounting interface.
CNC milling servicesTurning establishes concentric diameters, shoulders and seating faces. Any milled flat, slot or cross-hole remains related to those rotational features in the part drawing.
CNC turning servicesHousings with side ports, angled brackets or several working faces may require indexed machining. The setup preserves the specified relationship between the bearing seats and the surrounding mounting features.
5-axis machining optionsWe use the features that locate the tool or workpiece as the manufacturing references. A close outside dimension does not compensate for a misplaced contact face or mounting pattern.
A centering feature positions the adapter radially; a separate pin or pattern establishes its orientation. The chosen mating interface determines how those locating features avoid unnecessary constraint.
The contact profile is dimensioned from the gripper mounting references. Separate left and right geometry is identified where the intended grasp is not symmetrical.
The drawing relates bearing seats to their axial stops and adjoining mounting faces. Corner reliefs allow the intended face to seat rather than contact a mating radius first.
Openings and reliefs leave the selected connectors reachable. The complete tool layout provides the moving cable or hose envelope; an opening in an isolated plate does not establish clearance through robot movement.
Fitted interfaces and workpiece contacts need their own final-condition requirements, separate from the general exterior finish.
Finger contact surfaces follow the selected profile, texture and edge treatment. We do not add sharp texture or remove an edge that the gripping design uses to locate the workpiece.
For anodized aluminum, the allowance and coverage plan identifies locating bores, pin fits and threads. Those features are checked in the finished condition specified for assembly.
A separately defined polymer pad or insert can be replaced without remaking the whole finger or nest. Its retaining geometry and thickness remain part of the controlled contact definition.
The equipment references below show which dimensions define different parts of a robotic attachment. We inspect the custom part against its released drawing, including the mating fit and final surface condition.
Fastener patterns, radial location and angular location are checked as separate features. The gripping profile is measured from the same references used to mount the finger.

Values describe the named mating equipment, not universal robot geometry or adapter machining tolerances. The component drawing defines the mating pilot, pin, hole form and finished condition.
Our scope is machined components and the inspection specified in the quotation. Robot integration, gripping-force validation, payload assessment, functional safety and system repeatability remain separate responsibilities of the equipment program.
A component record needs to identify the mating equipment and contact geometry, especially when several tools share a similar plate or finger blank.
Each distinct gripping profile and receiving nest keeps its own part reference. Left/right markings follow the assembly definition rather than the orientation in which a part is packed.
The adapter and related spacers retain the interface drawing revision used for machining. An amended thickness, locating feature or tool pattern remains visible in the replacement order.
Packing separates gripping profiles, locating pilots and bearing seats from neighboring metal parts. Small replaceable pads and sleeves remain identifiable with their component references.
No. Interface details can change between robot models. Universal Robots, for example, documents four M6 tool-flange positions on the UR5e and six M8 positions on the UR20. We need the selected model and its tool-interface drawing rather than only the robot brand or payload class.
No. An adapter joins the two defined mechanical interfaces. An automatic tool changer also needs a validated locking mechanism and any required utility connections or status functions. We can manufacture a specified plate or component within that design, but a plate order does not include a complete tool-changing system.
Do not assume so. Extending the contact farther from the finger base changes the applied moment. Robotiq’s custom-fingertip guidance requires the design to remain within the gripper’s permitted moment and dimensional limits. The gripper designer must evaluate the new geometry before carrying an existing force or payload rating into it.
It defines the nominal shape, but the pocket also needs a decision about workpiece variation. Cast, molded or unfinished contact surfaces may differ from the final CAD surface. Identify the actual condition being gripped, its dimensional range and the intended relief or contact zones before releasing the finger profile.
No material choice alone establishes that result. Contact pressure, trapped debris, surface texture and the workpiece finish all affect marking. We machine the specified pad geometry and material; the equipment team evaluates it against the actual handled surface and acceptance criteria.
Yes, if it changes the tool’s position relative to the wrist. The integrator must account for the resulting offset in the assembled tool definition and review the relevant payload and movement conditions. Matching both bolt patterns does not make an adapter of a different thickness an unchanged tool configuration.
Use the assembly’s defined pairing. A single replacement is possible where both fingers have independent, interchangeable definitions. If they were fitted or finished together, the pair needs to be treated as that matched set. Identify the retained finger’s revision and condition rather than assume an unworn new profile will match its worn partner.
Selected equipment dimensions retain their model-specific scope; material data retain their grade and test condition.
Share the part model, drawing, material and quantity. Include the selected robot or gripper interface and the workpiece contact geometry where they define the component.
