In this article, we describe the services of CNC contract manufacturing and explain our approach to CNC contract manufacturing and its advantages.

CNC Contract Manufacturing Services

CNC contract manufacturing services include CNC turning, CNC milling, CNC drilling, CNC grinding, and CNC thread cutting. Manufacture of assemblies, assembly services, and technical consulting are among the complementary services offered as part of CNC manufacturing. They enable comprehensive project management – from individual part production and assembly to quality assurance and technical support.

The most common services of CNC contract manufacturing are described in detail in the following sections.

CNC Turning

CNC turning is an automated, subtractive manufacturing process based on the machining of a rotating workpiece.

In CNC turning, a workpiece is clamped onto the CNC lathe, set in rotation, and shaped in preprogrammed machining steps. CNC turning can be used to produce precisely fitting turned parts that are used in mechanical engineering, sanitary engineering, and the electrical industry, among other areas.

CNC turning makes it possible to deliver high quantities with consistent quality. The computer-controlled lathe ensures high dimensional accuracy and increased productivity.

CNC Milling

CNC milling is a computer-aided machining process in which a computer-controlled multipoint cutting tool machines workpieces with high precision.

In CNC milling, the tool path, speed, and cutting depth are specified by preprogrammed G-code or by alternative programming languages and control formats. In CNC milling, the workpiece is placed on the work table and machined by milling cutters. Either the milling cutter, the work table with the workpiece, or both move synchronously.

A major advantage of CNC milling is its high precision when it comes to complex geometries and complicated designs. CNC milling can be used to produce very precise drill holes, threads, and grooves that meet tight tolerances.

CNC Drilling

CNC drilling is a subtractive manufacturing process that uses computer control to create holes in workpieces made of metal, wood, plastic and other composite materials.

CNC drilling works with the help of pre-programmed drills that move within predefined coordinates and drill holes at specified depths and diameters.

CNC drilling allows tolerances in the range of approx. 0.01 mm to be maintained. Complex drilling patterns with different drill diameters in a single component can be easily implemented using CNC drilling.

CNC Grinding

CNC grinding is a process that uses a CNC grinding machine with a rotating grinding wheel for the fine machining of hard workpieces.

The rotating grinding wheel of the CNC grinding machine removes fine chips from metal workpieces. A computer controls the movements and parameters of the grinding machine, such as speeds, feeds, and positions.

CNC grinding is characterized by very high precision in the µm range. It enables a clean surface quality and the machining of hard materials, including steel and ceramics.

CNC Thread Cutting

CNC thread cutting is a computer-controlled process in which precise threads are produced using, for example, a tap or thread former.

During thread cutting, the CNC control system takes over the entire movement of the tools, such as taps and thread formers, which runs precisely in sync with the spindle rotation of the machine.

CNC thread cutting ensures automated production that delivers consistent thread quality.

Assembly and installation are complementary services that are often based on CNC-manufactured individual parts. The manufacture and installation of assemblies involves joining, adjusting, and testing several components to form a functional unit.

Manufacture of Assemblies

CNC contract manufacturers take on the manufacture of assemblies using common processes such as CNC turning, milling, and drilling. The basis for the production of assemblies is formed by the individual customer specifications in technical drawings and CAD models. The CNC contract manufacturer takes on the programming of the CNC machines, the production process, and the necessary quality controls.

Assembly Services

CNC contract manufacturers offer comprehensive assembly services according to customer specifications. Assembly involves the professional combination of individual assemblies or components to form functional components.

Consulting

CNC contract manufacturers offer comprehensive consulting on the CNC manufacturing processes to be used and the materials involved. CNC contract manufacturers are well versed in certification requirements, standards, and the relevant production standards. Based on their expertise, CNC contract manufacturers provide material recommendations and information on possible manufacturing processes and post-treatment.

As an experienced CNC contract manufacturer, Flühs Drehtechnik offers expert advice and precise implementation of individual assembly projects. We are a reliable CNC contract manufacturer for turned parts, implementing customer-specific requirements to a high standard of quality.

At Flühs, CNC contract manufacturing is cost-efficient and of the highest quality.

Our wide range of machinery enables us to offer a variety of manufacturing processes that are precisely tailored to customer specifications. Our turn-mill centers allow turning and milling to be combined in a single machining step, which increases process reliability and reduces production time.

As a CNC contract manufacturer, Flühs produces turned parts in small, medium, and large series. In addition to the contract manufacturing of turned parts, Flühs offers cost-effective solutions for the production of individual assemblies based on the turned parts produced. We primarily use alloys made of brass, stainless steel, and red brass.

Our advice on CNC contract manufacturing is based on decades of expertise. We have a high level of material expertise and will find the best solutions for your needs.

The CNC contract manufacturing process is divided into several steps. In the first step, we calculate the turned part based on the customer's technical drawing and CAD model and select the optimal machine type. We then manufacture part-specific tools and create the machine program.

Before the actual CNC production, we provide the appropriate measuring equipment on the machines and carry out the machine setup. After the machine setup, an initial acceptance test is carried out. Only after the acceptance test does series production begin, with continuous and final quality controls.

As a CNC contract manufacturer, Flühs supports its customers from the initial consultation through production and assembly to delivery of the components. Regardless of the batch size, we offer precisely fitting, tailor-made turned parts as individual items, prototypes, and in series production.
