Drawing-based parts can be reviewed alongside standard components and specified brands. Feasibility, material, critical dimensions, inspection scope and delivery are confirmed against the current drawing and project requirements.
Customization supports the existing nine product families, addressing installation, connection, locating and locking requirements beyond standard catalog options. Manufacturing arrangements follow the part’s requirements, with mating components coordinated in the same project.
Review of bores, hubs, keyways, set-screw holes, flanges and mounting features for the machine layout and shaft interface. Tooth profile, pitch and belt width are considered alongside the matching belt, connecting the pulley geometry to its drive function.
Coordination of end journals, shoulders, threads, reliefs and travel requirements around support bearings, locking nuts, couplings and drive connections. End machining is reviewed with the nut mounting arrangement and support configuration.
Drawing review and custom supply for locating pins, stepped pins, locating bushings and related components. Attention goes to mating fits, lead-in features, locating length, removal access and wear requirements at contact surfaces.
Assessment of custom screws, shouldered fasteners, locking parts and connectors, including head geometry, threads, shoulders, tool interfaces and available assembly space. The fastening function is considered in relation to the connected parts and their loading requirements.
Similar-looking parts can have different fit, loading and manufacturing requirements. Reviews start with the part’s function; material grades, treatments and acceptance criteria follow the agreed technical documentation.
| Part range | Geometry and interface considerations | Material and process considerations |
|---|---|---|
| Timing pulleys | Tooth profile and pitch; tooth count and belt width; bore and keyway; hub, flange and mounting datums. | Material grade, blank and machining route; surface treatment and its effect on mating dimensions; heat-treatment requirements where applicable. |
| Ball screw ends | End journals and shoulders; support bearing fits; threads and locking features; coupling interface; travel and installation length. | Original screw specification and condition; feasibility and extent of end machining; protection of functional surfaces and compatibility with the original treatment. |
| Locating pins and bushings | Locating datums, mating fits, coaxial relationships, lead-ins, clearance features, engagement length and removal access. | Base material and contact-surface requirements; the relationship between heat treatment and grinding; surface condition and critical dimensions after treatment. |
| Special fasteners and locking parts | Thread system and direction, engagement length, shoulders, head and tool interfaces, and contact faces. | Material and strength requirements, thread manufacturing method, surface treatment and assembly environment; process suitability at load-bearing features. |
Technical review brings drawings, models, mating-part details and operating conditions together. Differences affecting function or acceptance are resolved before machining arrangements, reducing avoidable iterations at sampling and assembly.
Part numbers, revisions, dimensions and technical notes are checked across 2D drawings, 3D models and item descriptions. Discrepancies are recorded for resolution, giving manufacturing and inspection a common approved reference.
Mounting datums, mating surfaces, motion relationships and inspection priorities are identified. Dimensional and geometric requirements are reviewed alongside access for measurement, keeping acceptance criteria connected to the part’s actual function.
Part geometry, material, quantity and surface treatment inform the review of machining routes, tool access, treatment effects and assembly. Proposed adjustments are documented and confirmed before implementation.
The value of a custom part extends to the assembly around it. ZOFANG coordinates standard components, customer-specified brands and drawing-based parts, bringing their interfaces into one purchasing plan.
Ball screw ends are matched to support bearings, locking nuts and couplings; pulleys are considered with shafts, belts and fasteners. Mounting dimensions and connection details are cross-checked between the related parts.
Products from brands such as NSK, SKF, FAG, INA, HIWIN and TBI can be included in sourcing according to the customer’s specified models. Complete model designations and mating-part relationships are retained alongside custom drawings, with supply conditions confirmed for the project.
Standard and custom parts are linked to project or item references. Quotation scope, quantities, technical confirmation status and delivery arrangements are organized together, considering preparation lead times and assembly sequence.
Samples or batch supply are arranged according to the project. Assembly feedback, approved revisions and inspection priorities carry forward into subsequent orders, reducing repeated explanations and revision mismatches.
Where fit, assembly or function needs validation, samples can be arranged as agreed. Dimensional records, assembly feedback and adjustment decisions are tied to the same drawing revision, establishing the reference for subsequent batches.
Inspection is arranged around the approved drawing and acceptance criteria, covering relevant dimensions, fits, threads, appearance and treatment condition. Sampling scope, record format and accompanying documentation are agreed for the project.
Issues affecting drawing conformity or assembly are managed against the part number, revision and batch. Changes to a process or feature are confirmed before entering subsequent supply, reducing the risk of mixed or informal revisions.
Identification, documentation and revision records matter alongside the physical parts. Delivery documents and packaging arrangements follow the component’s needs, transportation requirements and assembly plan.
Part numbers, drawing revisions, quantities and batch references are linked as agreed. For coordinated assemblies, package identification can follow the assembly unit to support receipt checks, storage and production use.
The scope of inspection records, material documentation and treatment records is agreed for the project. Corrosion protection, separation and transport packaging are considered around precision fits, threads, tooth surfaces and other sensitive features.
Repeat orders build on the confirmed specification and revision. Changes to quantity, material, treatment or geometry retain corresponding records, while additional custom parts can be incorporated into the same component supply list.
From an individual part drawing to a machine component list, ZOFANG coordinates technical review, manufacturing arrangements and specified-brand sourcing.
