Product Overview
Instrument mechanisms can include racks, links, pins and forked connections with different functions.
This reference group is intended for selecting the individual part to review.
Structure & Mating Interfaces
Provide the selected component drawing, mating parts and movement path.
For a rack, define tooth engagement; for a link or pin, define its connection and guiding interfaces.
Engineering Focus
Why distinguish racks from links and pins in an instrument?
Each transfers or controls movement differently.
A rack needs a defined tooth relationship, while links and pins need defined joints or guidance.
Separating those functions avoids applying a single generic accessory specification to several mechanically different parts.
Manufacturing Route & Finishing
Compare forming and machining for each geometry instead of assigning one process to the group.
Working teeth, holes or sliding surfaces may need secondary finishing.
The proposed route is confirmed for your drawing, material and quantity. An image does not establish a fixed tolerance or a complete process specification.
Compare manufacturing capabilities →Materials & Surface Requirements
Provide the material specification, final surface requirements and documentation needed for the component.
Cleaning, traceability and device-related validation must follow the customer project.
The catalog reference does not establish medical compliance or an intended clinical use.
Review material-selection information →Quality & Sample Approval
Check the chosen part's functional geometry, movement clearance and final surface.
Agree material and inspection records appropriate to the project.
Specify the drawing revision and the condition in which each dimension is inspected. Record the agreed dimensional and functional checks before sample approval.
Quality documentation →Prepare a Product-Specific RFQ
- Component definition. Send the 2D drawing and 3D model, where available, with the drawing revision and the requested part or assembly scope.
- Mating information. Include the assembly references needed to define the interfaces discussed above.
- Delivered condition. State material, finishing and inspection requirements, identifying any items that need a manufacturing recommendation.
- Supply plan. Include sample needs, expected order and annual quantities, packaging requirements and target timing.
Product Questions
Can a reference group be quoted as one product?
Identify each part and quantity in the bill of materials; their geometry, finishing and inspection requirements can differ.

What must the sample approval requirements define?
Check the chosen part's functional geometry, movement clearance and final surface. Agree material and inspection records appropriate to the project.
Technical Context
The product-specific notes above identify drawing-review questions. General process and material references are collected separately; they do not verify a material grade, production qualification or performance claim for the pictured part.
