Tolerances according to 2D Drawing
By using 2D drawings, we can capture accurate tolerances and critical specifications.
Tolerances according to 2D Drawing in CNC Machining
At Batchforce, we strive to manufacture parts exactly to the specifications indicated on a 2D drawing. 2D drawings are a crucial part of the manufacturing process because they provide detailed information on required tolerances and finishes, ensuring consistent quality. This approach is applicable to a variety of industries, including medical technology, industrial equipment, aerospace and automotive.
Why is a 2D drawing necessary if I already have standard tolerances?
Standard tolerances such as ISO 2768 do not cover all critical dimensions and requirements. A 2D drawing provides the details needed to achieve the desired precision.
What information should I include on the drawing?
Specify critical dimensions, surface roughness, fit tolerances and GD&T symbols, as well as any engraving for traceability or brand identity.
What file formats does Batchforce accept?
We accept 2D drawings in PDF format, ideal for capturing technical specifications without loss of accuracy.
Our process
Control and inspection
according to 2D drawings
Our quality control processes are designed to accurately meet the requirements specified in your 2D drawings. For parts with detailed specifications, we follow a streamlined process that ensures each batch meets your exact requirements.
Analysis and validation tolerance requirements
For parts with high tolerances, we determine sample sizes and inspect based on ISO 2859-1, as described in our First Article Inspection (FAI) procedure.
Documentation in ERP system
All specific tolerances and requirements are recorded in our ERP system. This ensures that we maintain traceable and consistent production information.
Calibrated measuring equipment
Our measuring instruments, including digital three-point micrometers, Go/No-Go sets and digital calipers, are calibrated according to ISO/IEC 17025.
Inspection critical features
For parts with high tolerances, we accurately document all measurement results. This provides complete transparency in the production process.
Why are 2D drawings the standard for tolerances?
2D drawings make it possible to capture specific tolerances and requirements essential for parts with precise fits, critical surface roughness or specific dimensions. For many customers, using a 2D drawing is the best way to ensure that each part is produced exactly as required.
- Accuracy and consistency: Critical dimensions and tolerances are followed exactly, ensuring consistent quality, batch after batch.
- Assured functionality: Parts are manufactured to their precise functional specifications, increasing reliability and performance.
- Reduced failure costs: Early reconciliation to detailed tolerances prevents errors, re-production and delayed deliveries.
What specifications can we capture according to a 2D drawing?
On a 2D drawing, we can define specific tolerances and finishing requirements that often go beyond standard tolerances. The following aspects are examples of what you can specify on a drawing:
- Critical Dimensions and Strict Tolerances
- Why: Parts with critical tolerances, such as moving parts or parts that must fit perfectly, require specific tolerances beyond ISO standards.
- Example: A shaft that must fit closely in a bearing, with an H7/g6 fit.
- Surface Finish.
- Why: For visible parts or sealing surfaces, surface smoothness is essential to meet aesthetic or functional requirements.
- Example: A medical enclosure with a smooth surface for hygiene and a high-quality appearance, specifying an Ra value.
- Fits and Limits for Compounds.
- Why: Fit tolerances are required for parts that must fit together precisely, such as bearings, gears or housings.
- Example: An assembly where parts must fit exactly to an H7/g6 tolerance to ensure reliable operation.
- Geometric Tolerances (GD&T).
- Why: Complex tolerances such as parallelism, concentricity or roundness are often required in parts that need precise alignment.
- Example: A cylindrical part that must match exactly with another part in the assembly.
- Drill Holes and Thread Specifications
- Why: Precise drill holes and threads require specific dimensions, including diameter and depth, for reliable assembly.
- Example: Threads with specifications such as M6x1.5 for fasteners, essential for critical connections.
- Bevel and Radii
- Why: Specific chamfers and radii are important for the functionality and safety of parts, as well as for their appearance.
- Example: A bevel of 0.5 mm at the edges to avoid sharp corners and improve the fit.
- Engraving of Part numbers or Logos
- Why: For traceability and brand recognition, it may be necessary to engrave part numbers or logos directly on the part, with accurate dimensions and placement.
- Example: A serial number engraved on parts in the medical or aerospace industry so that each part can be uniquely identified for quality control and documentation.
By clearly recording these specifications on a 2D drawing, we can ensure that every aspect of the part meets your functional and visual requirements.
