Understanding and prioritizing technical specifications is essential for international B2B buyers sourcing metal lathe machining services or equipment. The following core properties directly influence performance, cost, and suitability for your production needs:

Material Grade
The type of metal or alloy being machined—such as aluminum (e.g., 6061, 7075), stainless steel, carbon steel, or cast iron—impacts machinability, cost, durability, and final application. Material grade determines tool wear, achievable surface finish, and compliance with industry standards. Buyers should always specify material grades aligned with their sector (e.g., automotive, energy) and verify supplier certifications for traceability.
Dimensional Tolerance
Tolerance defines the allowable deviation from specified dimensions (e.g., ±0.01 mm). Tighter tolerances indicate higher precision but may increase machining time and cost. For sectors such as aerospace or medical devices, tight tolerances are often non-negotiable, while in construction or mining, standard tolerances may suffice. Clear communication of tolerance requirements minimizes production delays and quality disputes.
Surface Finish (Ra Value)
Surface roughness, usually measured in micrometers (e.g., Ra 1.6 μm), affects the appearance, fit, and performance of machined parts. A smoother finish prevents premature wear and ensures optimal assembly, especially for parts involving sliding or rotating contacts. Specifying required Ra values is crucial for applications like hydraulic equipment or sealing components.
Hardness
The hardness of a material or machined component, often measured on Rockwell (HRC) or Brinell (HB) scales, relates to wear resistance and lifespan. Parts requiring high durability or operating in abrasive conditions may necessitate harder materials or post-machining heat treatment. Buyers should ensure suppliers can certify final hardness, particularly for high-demand sectors.
Concentricity and Roundness
These geometric properties are critical for rotating parts such as shafts or bushings. High concentricity reduces vibrations and mechanical failure, enhancing operational stability. It is vital to include concentricity/roundness tolerances in RFQs when sourcing precision components.
Production Lot Size and Repeatability
Consistency across batches is fundamental for international supply chains. High repeatability (ability to produce identical parts over multiple runs) is non-negotiable for global buyers aiming for seamless assembly and minimal QC intervention. Production lot size also impacts unit costs and lead times, informing commercial negotiation.

Essential Trade Terminology for Global B2B Transactions

Refers to a company that produces parts or equipment to be marketed by another firm, typically under the latter’s brand. For buyers, working with OEMs can facilitate custom solutions, integrated engineering support, and better quality assurance compared to generic manufacturers.
MOQ (Minimum Order Quantity)
The smallest quantity a supplier is willing to produce or sell in a single order, often impacting unit price and production scheduling. Buyers should clarify MOQs upfront to avoid unexpected cost escalations or production delays, especially when piloting a new component or entering an unfamiliar market.
RFQ (Request for Quotation)
A formal document issued to suppliers outlining detailed requirements—drawings, materials, tolerances, quantities—to solicit precise pricing and lead time information. Structuring clear and comprehensive RFQs is critical for efficient supplier comparison and negotiation, while reducing the risk of miscommunication.
Incoterms (International Commercial Terms)
Standardized trade terms published by the International Chamber of Commerce (ICC), such as EXW, FOB, and DDP. Incoterms clearly define responsibilities for shipping, insurance, customs clearance, and transfer of risk. Misunderstanding Incoterms can lead to hidden costs or shipping disputes, so buyers must specify the preferred term in contracts.
Certificate of Conformity (CoC)
A legal document provided by the manufacturer or supplier certifying that goods meet specified standards or technical requirements. Requesting CoCs minimizes compliance risks, particularly when importing to tightly regulated markets in Europe or the Middle East.
Lead Time
The total time from order placement to delivery, encompassing production, inspection, and shipping. Accurate lead time estimates underpin effective inventory planning and customer fulfillment, especially for cross-border supply chains with variable customs or transport durations.
