Abstract

As the core basic component of the globalindustrial manufacturing chain, standard machining parts and non-standardcustom machined parts run through the whole production, assembly, operation andmaintenance process of automation equipment, heavy machinery, new energyequipment, aerospace and industrial intelligent equipment. Supported by 5-axisCNC machining, turning, milling and precision grinding technology, two types ofmachined parts solve universal assembly demands and personalized customizedstructural demands respectively, optimize industrial production efficiency,reduce equipment manufacturing costs, and promote the upgrading ofstandardized, modularized and intelligent global industrial manufacturing. Thisarticle analyzes the application scenarios, industrial value and long-termdevelopment trend of standard and custom mechanical parts in modern equipmentmanufacturing industry.

1. Definition & Core Difference BetweenStandard Machined Parts and Custom Machined Parts

In modern precision machining industry,industrial mechanical parts are divided into standard machining parts andnon-standard custom machined parts according to production standards and usageattributes, which are classified clearly for global industrial procurement:

1.1 Standard Machining Parts

Standard machined parts refer to mechanicalcomponents produced in batches in accordance with ISO, DIN, ANSI, GB unifiedinternational industry standards, including standard bolts, bearings, gearshafts, pin shafts, flange connectors, standard bushings and fasteners.Features: unified size, unified tolerance, interchangeable assembly, massproduction, low unit cost, universal compatibility for mainstream industrialequipment.

1.2 Non-Standard Custom Machined Parts

Custom machined parts are personalizedcomponents customized according to equipment design drawings, working conditionparameters and special installation demands, processed by CNC turning andmilling composite machining. It includes special-shaped structural parts,corrosion-resistant alloy parts, high-precision positioning parts, equipmentmodified connectors, special fixture parts. Features: one-to-one drawingproduction, customized material and tolerance, adapt to special workingconditions, non-interchangeable, applied to differentiated industrial equipmentR&D and upgrade.

2. Wide Application of Standard &Custom Machined Parts in Industrial Equipment Manufacturing

Benefiting from mature precision machiningtechnology, anti-corrosion surface treatment and strict tolerance control,machined parts have become indispensable basic components for segmented globalindustrial manufacturing fields, covering full industrial chains:

2.1 Automation & Intelligent ProductionEquipment

Standard fasteners, linear shaft parts,standard gears ensure the stable assembly of conveyor lines, robotic arms,automated assembly machines; custom special connecting brackets, eccentricpositioning parts solve the matching problem of non-standard automationfixtures, improve the running stability of intelligent production lines, andreduce equipment failure rate.

2.2 New Energy Industrial Equipment

For photovoltaic equipment, energy storagecabinet equipment, wind power auxiliary machinery: standard high-strengthanti-rust bolts, standard bearing seats adapt to outdoor high-temperature andhumid working environments; custom aluminum alloy lightweight structural parts,copper conductive precision parts meet the lightweight and conductivecustomized design requirements of new energy special equipment.

2.3 Heavy Machinery & EngineeringEquipment

Engineering machinery, hydraulic equipment,mining machinery adopt high-hardness standard gear parts, hydraulic standardvalve cores to realize standardized assembly; custom wear-resistant steelstructural parts, special oil cylinder connecting parts adapt to high-load,impact-resistant harsh working conditions of engineering sites.

2.4 Medical, Food & Packaging Machinery

Food packaging equipment and medicalautomation equipment use food-grade stainless steel standard machined parts tomeet hygiene standards; custom polished non-standard cam parts, silent rotatingparts realize equipment silent operation and food safety production.

2.5 Aerospace & ************* PrecisionEquipment

High-precision standard aviation fastenersguarantee equipment assembly safety; micro customized alloy machined partssupport ultra-precision assembly of ************* testing equipment andaerospace auxiliary equipment, with tolerance controlled within ±0.005mm.

3. Positive Influence of Dual-Type MachinedParts on Global Industrial Manufacturing

The coordinated application of standardmachined parts and custom machined parts reconstructs the operation logic ofmodern industrial equipment manufacturing, bringing multi-dimensionalindustrial reform value:

3.1 Realize Modular Production, ShortenEquipment Manufacturing Cycle

Enterprises adopt batch stocked standardparts for universal assembly links, no secondary customized processingrequired; only customize special structural parts for equipment personalizedlinks. This mode cuts 30%-45% of equipment overall processing cycle, helpsmachinery manufacturers quickly complete prototype development and massdelivery.

3.2 Control Comprehensive ManufacturingCost, Optimize Supply Chain Layout

Mass-produced standard parts have maturesupply chain and low procurement cost; custom parts replace integral castingparts, reduce material waste and post-processing difficulty. For medium andsmall equipment manufacturers, the matching use of two parts can reduce overallcomponent procurement cost by 20% on average, and simplify global spare partsreserve management.

3.3 Improve Equipment Adaptability &Service Life

Standard parts follow internationalindustrial wear resistance and strength standards, with stronginterchangeability and convenient later maintenance; custom parts are customizedaccording to equipment load, temperature, corrosion working conditions,targeted improving equipment structural strength. The combination greatlyextends the service life of industrial complete equipment.

3.4 Boost Diversified IndustrialManufacturing Upgrade

Traditional industrial manufacturing islimited by unified component specifications, difficult to realizedifferentiated equipment iteration. The popularization of low-cost rapid CNCcustom machining makes small-batch, multi-model, personalized industrialequipment production feasible, promoting the transformation of manufacturingindustry from standardized mass production to customized intelligentproduction.

4. Current Industry Pain Points &Optimization Development Direction

4.1 Common Industry Pain Points

1. Many small machining factories haveinconsistent tolerance of standard parts, poor international standardcompliance, unable to adapt to cross-border equipment assembly;

2. Custom parts processing cycle differsgreatly, low-precision processing leads to poor assembly matching;

3. Lack of unified material selectionstandard for dual parts, insufficient anti-corrosion and wear resistance forextreme working conditions.

4.2 Future Development Trend of MachinedParts Industry
