Drawing parts: A specialty in CNC machining

In the fast-paced world of CNC machining, the distinction between drawing parts, production parts and special parts plays a crucial role in optimizing production efficiency.

CNC24 uses advanced technologies and in-depth industry knowledge to ensure that all processes are efficiently designed and state of the art.

This article deals in particular with the special features of drawing parts, which have a very high degree of individualization.

Drawing parts: Individualization at the heart

Drawing parts are characterized by their individuality, as they are manufactured according to unique customer specifications.

These parts are indispensable when off-the-shelf components are not sufficient because of special material requirements, dimensional precision and other specific technical requirements.

Due to the special requirements, a close partnership between customers and manufacturers is necessary. Special production tools often have to be developed to make the degree of customization possible.

What are drawing parts?

Drawing parts, also known as special parts, are manufactured according to specific customer requirements . These parts are indispensable when standard or standardized parts are not sufficient due to special technical requirements, e.g:

• Use of special materials
• High surface quality with tight tolerances
• Non-standardized dimensions
• Desired hardness
• Corrosion resistance
• Special thread forms
• Other unique technical features

Prototypes, which are often produced as drawing parts, are an example of these requirements, as a standardized part may not be available at the time of production. Small and large series are also often produced as drawing parts in order to meet precise requirements.

Important notes on ordering drawing parts

Ordering a drawing part differs considerably from ordering a standard part due to the individual characteristics of each part. As there are no standardized standards for drawing parts, close cooperation between the customer and the manufacturer is essential during the development phase.

This cooperation ensures that the technical requirements are harmonized with the capabilities of the manufacturer's machinery.

Typical products for drawing parts

Drawing parts can basically be all workpieces that deviate from existing DIN norms and technical standards. Common examples are:

• Turned parts: These are produced by clamping the workpiece in a lathe, which then rotates while a cutting tool shapes the workpiece into the desired form. Drawing parts can be turned on manual lathes for prototypes or on automated CNC machines for series production.
• Milled parts: In this process, a milling tool with a specific geometric contour is moved over the workpiece in order to obtain the desired shape by gradually removing material.
• Punched parts: During punching, a flat, thin workpiece (e.g. sheet metal) is placed in a press equipped with a die that corresponds to the desired shape.

Welded constructions: Typically steel structures consisting of various elements such as profiles, frames, tubes or arches, which are joined together using suitable welding processes such as MIG or TIG welding.

Challenges in the production of drawing parts

The biggest challenge in the production of drawing parts is that there are no technical standards and norms for the required parts.

The construction and technical design of the part therefore play an important role. It is crucial to find the most cost-effective production method in close cooperation between the customer and manufacturer.

About CNC24

CNC24, a brand of CNC24 GmbH, is a digital B2B procurement platform through which individual precision components can be sourced transparently and efficiently. Manufacturers from 22 countries produce the mechanical components individually according to customer specifications. The manufacturing processes offered by the leading online marketplace for mechanical engineering include turning, milling, sheet metal processing and additive manufacturing.

With its innovative platform solution, the technology company creates a transparent process for the procurement of production parts and digitalizes the value chain through to a fully automated procurement process.

The company's successful positioning as a partner for SMEs in the field of digitalization and innovation was confirmed in 2023 when it was awarded the German Excellence Award in the "Digital Startup Champions" category and the "Employer of the Future" seal. Thanks to its global network of suppliers, the company can guarantee free capacity, high material availability and on-time delivery of components at all times.

For quality control, all parts undergo an additional inspection process in the in-house measuring center before they are delivered. CNC24 was founded in 2019 by co-founders Willi Ruopp and Marlon Gerat. The start-up serves all industrial sectors with a need for production parts - from special machinery and plant engineering to IOT and medical, testing and measurement technology.
