Product Overview
Discs and rings within a combination-lock mechanism coordinate rotation and engagement through defined openings and profiles.
Similar outlines can have different indexing requirements.
Structure & Mating Interfaces
Provide the stack arrangement, central drive and relative angular positions.
Distinguish contact or indexing edges from clearance regions.
Engineering Focus
Why include the stack arrangement of lock discs?
Disc thickness, orientation and working openings act together in the assembled mechanism.
An individual disc can meet its own dimensions without establishing the full sequence.
The stack arrangement identifies the relationships that must be verified across the parts.
Manufacturing Route & Finishing
Compare PM, MIM and machining for the disc profile and any integrated features.
Critical thickness and working profiles may need dedicated finishing or inspection.
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
Specify the base material, final condition and corrosion or appearance requirements.
Mark drive, guiding and contact surfaces that must meet their dimensions after treatment.
The component specification does not establish a security rating for the complete lock.
Review material-selection information →Quality & Sample Approval
Check thickness, angular relationships and movement within the intended stack.
Define the engagement sequence and acceptable clearances.
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 combination-lock discs be approved individually only?
Individual measurements are needed, but stack fit and the required sequence should also be checked with the mating components.

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.
