Drawing-Based Components for Custom Mining Equipment

Application Scope

Winworth manufactures non-standard replacement and custom components for mining and heavy equipment when the buyer provides an approved drawing or authorizes a controlled reconstruction process. Typical routes include cast, forged, fabricated, machined, heat-treated, coated, or assembled parts within Winworth's confirmed manufacturing scope.

This page does not describe a complete custom mining machine. Motors, drives, gearboxes, bearings, hydraulics, controls, safety systems, structures, process design, installation engineering, and commissioning remain outside the default scope unless explicitly defined in an approved order.

Drawing, Sample, and Reconstruction Hierarchy

An approved drawing and revision are the controlling source. If only a sample is available, classify every surface as functional, datum, mating, worn, damaged, repaired, coated, machined, as-cast, or unknown. Record current dimensions and identify which dimensions represent original design and which require buyer decision.

Photographs can identify equipment position, orientation, damage, access, and adjacent parts, but they do not establish scale, tolerance, hidden geometry, material, heat treatment, internal defects, or unworn profile. A sample also cannot prove load capacity, safety factor, interchangeability, or upgrade suitability.

Where the buyer requests a design change, requested material change, reinforcement, dimensional correction, or service-life improvement, document the design authority, operating inputs, failure analysis, affected interfaces, validation method, and approval responsibility. A reproduction order and an engineering upgrade are different scopes.

Engineering, Manufacturing, and Quality Plan

Provide equipment maker and model, machine and part function, assembly context, drawing history, sample condition, mating parts, load and motion inputs, duty cycle, wear or failure observations, original material, requested material, manufacturing route, heat treatment, weld and repair limits, machining allowance, datums, fits, tolerances, surface requirements, fasteners, lubrication, lifting, installation, and removal.

The approved quality plan may include material identification, chemistry and mechanical-property records, dimensional inspection, scanning or template comparison, hardness mapping, specified NDT, weld procedure and inspection, heat-treatment records, coating, pressure or leakage tests when relevant, trial fit or assembly, marking, and document review.

Winworth does not claim OEM authorization or guaranteed equivalence. Interchangeability applies only to the approved interfaces and acceptance criteria; it does not imply identical proprietary design, machine certification, capacity, safety performance, wear life, or warranty.

RFQ Information

Provide all available drawings and revisions, equipment identification, part position and function, sample and photographs, unworn reference features, mating-part data, failure history, operating and load inputs, material and heat treatment, requested changes, design authority, manufacturing route, tolerances, NDT and tests, quantity, records, packaging, lifting, destination, and requested delivery schedule.
