What does CNC turning actually mean?

During turning, the fixed part made from a material to be machined (metal, plastic or wood) rotates at high speed.
The turning tool attached to the slide then moves against the workpiece made of bar material with a feed motion.
The rotary motion of the pressed material and the feed of the tool takes material away from the workpiece.
Therefore, all manufacturing machining processes, such as turning but also milling, are called cutting processes or subtractive processes.
In modern machining centres, driven tools combine various turning and milling techniques. For example, flat wrenches, threads or hexagons can be produced directly on one machine.

What else is possible after CNC turning?

The finished turned part is generally ready for immediate use.
Our partners work very precisely and accurately in their turning processes. If there are special requirements for the condition of the outside part or if normal slight machining marks are unwanted, this is not a problem.
The improvement, appearance, abrasion protection and corrosion prevention of turned components are as important to our partners as they are to us.
Service Steelparts has suppliers that offer all the benefits of high-quality surface finishing technology.
This remains all the way down to the last working step. The effective production of complex precise parts is carried out from A to Z according to customer requirements.

Working steps in CNC turning in brief

Preparation of semi-manufactured products

Cutting processes such as saw cutting, laser cutting, flame cutting or water jet cutting are used to prepare the turned material from materials such as steel, aluminium or plastic – semi-finished products.

CNC turning setup

In order to prepare the machine tool for the production of a turned part, the required semi-finished product is fixed with suitable turning and milling tools. Experienced and highly skilled employees supervise the process.

CNC turning machine programming

The machining program (NC program) of the CNC machine controls the commands for producing the finished part from the semi-finished part. In the modern infrastructure of computer-controlled systems, programming is done with CAM software.

Manufacture of turned part

After preparation, the actual CNC machining is carried out in basic and additional stages. The measurement of the finished part completes the manufacturing process.

Sample turned parts we have delivered to our customers:

Complex turned parts are welcome! Delivering perfect turned parts is not only our profession. It is also our passion.

As a competent online manufacturer, Service Steelparts offers an almost fully automated ordering process for its CNC turned parts.

About CNC turning and CNC milling – no matter whether axial and radial bores, cylindrical shapes, slots, grooves and flats – Service Steelparts is the professional partner for machining technology.

Highest precision is something natural for us.

Turned parts must be able to be assembled and used precisely and in a process-stable way, and must be proven to be strong in long-term use.

Of course, this avoids later slack in the production process and costly rework.

Modern logistics of procurement

The procurement logistics at Service Steelprats is modern and up-to-date. Customers today prefer digital communication via the internet. Most of them prefer to get in touch via email through the website or inquire over the phone for their CNC turning inquiries.
Once the customer gets a general idea and all the required offers, the turned parts are ordered from Service Steelprints via email or through the customer portal. As a full manufacturing partner, we count on economical and digital processes.
The desired parts are delivered on the agreed delivery date, of course, similarly to the transport service provider. Re-orders of already manufactured parts and components are even faster. This is because the files, drawings and settings used in CNC turning can be easily saved and archived at the customer’s request.
Calculating and ordering in the Service Steelprats online shop is explicitly simplified. The customer uploads a CAD model (STEP file) and a technical drawing (PDF format) of the part to be produced, specifies the desired material, the number of parts (from 1 to 10,000) and the preferred delivery date.
The technical drawing shall contain more detailed information on specific manufacturing tolerances, materials, fits, threads and surfaces. In summary, all the information you need to enable us to manufacture complex functional components with the highest technical requirements for you safely and accurately.

Delivery time, production and service

Service Steelparts orders most of its orders from partners with their own production lines. As a professional digital manufacturer in the machining sector, Service Steelparts knows what the high expectations are for a modern CNC service provider.

The average delivery time for ordered turned parts is 15-20 working days. As an express service, it can also be delivered faster – in 9-12 working days. The super express service delivers parts fastest within 72 hours.

If for reasons of capacity, or due to rare special requests, orders are outsourced, only qualified suppliers are used. Service Steelparts regularly subjects its partners to a demanding quality check.

Quality assurance also includes checking each order individually for all customer-specific manufacturing tolerances and quality characteristics prior to shipment. Steelparts Service always remains the first and only point of contact with the customer.

The customer receives their turned parts with the highest precision, speed and quality from a single source. This applies to all production and service stages of CNC turning. Service Steelparts employees are happy to clarify any queries or special requirements at short notice via email, chat or phone.
