Turning parts and tools for CNC turning

What is CNC turning?

CNC turning is a manufacturing process in which the workpiece to be machined rotates around its own axis at high speed while a fixed cutting tool is held against the workpiece. This tool removes material evenly through feed movements until the body has the desired shape.

Thus, both CNC turning and CNC milling are a manufacturing process that can be assigned to subtractive manufacturing. The abbreviation CNC stands for Computerized Numerical Control and means that the numerical control is carried out by a computer and therefore even complex workpieces can be manufactured automatically with a high degree of precision.

Shapes of turning parts

CNC turning part

In contrast to CNC milling, only bodies with rotational symmetry can be generated by CNC turning. Typically, these turning parts have cylindrical or conical shapes. Planar surfaces occur only at right angles to the rotational axis and holes are drilled along it. If the workpiece is also to undergo additional milling or drilling work apart from the rotary axis, a lathe with a driven tool or a CNC machining center is required for machining. The process in this case is also referred to as CNC complete machining. Materials suitable for CNC turning are in particular steels, aluminum and copper alloys as well as machinable plastics.

Bar turning for simple contours

Bar turning is used in particular for very large workpiece series. In this manufacturing process, different machining processes can be carried out in the same clamping process. Usually, there are several tool turrets that machine a workpiece at the same time. This efficient machining process achieves fast cycle times and can thus minimize costs, especially in the case of large production runs. In bar turning, the tool moves along the Z axis while the material remains stationary.

Swiss turning for the production of slim turned parts

Swiss turning is used for the production of small, complex precision parts and long, narrow components. The raw material moves along the Z-axis. The driven tools on the Swiss lathe are capable of machining holes, threads or milled surfaces. Most Swiss lathes have a loading magazine into which the operator inserts the bar stock. The machine feeds this material, processes it and throws the completed part onto a conveyor belt.

Examples for different turning processes

  • Face turning to produce a flat surface 

Facing is a process for creating a flat surface perpendicular to the rotational axis. A distinction is made between cross facing as the first turning operation and cutting off to produce three surfaces simultaneously on a workpiece.

  • Form turning for complex geometric shapes

In this manufacturing process, the final shape of the tool is created by the feed or cutting movement of the workpiece. By means of form turning, any rotationally symmetrical forms can be integrated into the outer contour of the turned part.

  • Taper turning for shaft-shaped turned parts

Taper turning generates conical shafts on a CNC turned part. The rotary axis of the turned part is at a certain angle to the turning tool. This process can be used to generate metric tapers, Morse tapers, hollow shank tapers and steep tapers, for example.

  • Thread turning for the manufacture of CNC turned parts with threads

To machine a thread into a CNC turned part, a thread chisel is used. The desired thread pitch determines the feed-rate movement of the tool. During threading, the turning tool is guided through the same track several times in succession because the cutting force would not be sufficient with a single feed.

  • Roller turning for the production of rotationally symmetrical rolling surfaces

This manufacturing process is used to give a profile to cylindrical turned parts. Turning is performed by means of a rolling motion. In this way, rotationally symmetrical or helical rolling surfaces are created.

Complete machining of your workpieces

The complete machining of your turning parts is done in modern CNC turning centers. They allow economical production using various production techniques such as turning, drilling or milling. The production processes at our manufacturing partners are optimized in such a way that the parts are processed in a single machine with as few clamping operations as possible and are then ready for use.

This reduces the production time and hardly any follow-up work is necessary. A flexible machine design also enables the complete machining of complex turned parts including many fits and threads. The complete machining of CNC turned parts in one clamping optimizes factors such as costs, time and the quality of the work for our customers.

Surface treatments for CNC turning parts

For the production of your CNC turned parts we offer you a full service in cooperation with our production partner network. At your request, this also includes surface treatments of the workpieces to protect them from corrosion, wear and premature ageing processes, for example.

  • Heat treatments

In order for the workpieces to meet the high requirements of durability, material hardness and toughness in later use, additional heat treatments are carried out on the turned parts. This includes hardening of ferrous materials, quenching and tempering of metals, surface hardening and nitriding.

  • Electroplating

The process of galvanization, an electrolytic process in which the turned part to be machined functions as a cathode, creates a coating on the surface of the workpiece. This increases, among other things, the resistance of the turned part. Together with our partners we offer the following services: burnishing, passivating, phosphating, chrome plating, nickel plating and zinc plating.

  • Mechanical finishes

Upon request, our manufacturing partners can carry out mechanical processing such as grinding and polishing, sand or glass bead blasting and engraving after the CNC turned parts have been manufactured.

You receive everything from a single source and save the cumbersome task of commissioning several service providers.

Typical applications of CNC turning

CNC turned parts are usually cylindrical or conical bodies. We are very flexible in the choice of raw materials. You can order CNC turned parts in over 50 different steels, aluminum parts, over 40 different types of plastics and metals such as copper, bronze, brass and titanium.

On-demand production of CNC turned parts according to customer requirements

The production and manufacture of CNC turned parts are under strong competitive pressure due to digitalization and globalization. The effectiveness of production is an essential success factor. Supply chain management therefore already plays a central role in day-to-day production. The development towards industry 4.0 will further shorten production cycles in the future.

In order to secure long-term market opportunities, the production of CNC turned parts requires maximum flexibility. However, this always leads to risks, for example when it comes to processing production peaks on schedule. With the On-Demand-Service of FACTUREE you protect yourself against such risks, because we are able to implement your orders quickly and thus give you the necessary degree of flexibility to survive in your markets.

Metal turned parts

Steels, stainless steels, aluminum alloys as well as copper, brass, bronze and titanium are among the materials frequently requested for the manufacturing of CNC turned parts. These metals are constantly available from our manufacturing partners, so that we can guarantee you a quick start to your order. You save the costs for the material procurement and storage and profit from the quantity discounts of our manufacturing companies. In metal processing, robust production machines are used which are able to produce CNC machined parts in large quantities with high precision. The cooling lubrication in the machines ensures that the chips created by the machining process are transported out of the working area and that the manufacturing process is not interrupted by cleaning.

Turning aluminum

Higher cutting speeds and lower cutting forces are required for manufacturing aluminum turning parts than is the case with, for example, steel. The machinability of aluminum depends decisively on the alloying additions. Pure aluminum without alloy additives is not suitable for turning. Its tensile strength is too low and at 660° Celsius the melting point of pure aluminum is also below the temperature generated during turning. For turning aluminum, alloys are needed that increase the strength of the material. Cold-worked or hardened aluminum alloys are ideally suited for aluminum turned parts.

Turning steel

When turning steel, the settings of the cutting data must always be adapted to the category of the steel to be machined. Roughly speaking, steels are divided into unalloyed, low-alloy and high-alloy steels. Unalloyed steel has a carbon content of up to 0.55 %. Manufacturing turned steel parts from unalloyed steel is challenging, because unfavorably shaped chips and the formation of built-up edges on the tool often occur. These adversely affect the geometry.

For low-alloy steels, machinability depends on the composition of the alloy and any hardening treatments. In the case of hardened materials, high temperatures occur in the cutting zone during the production of turned steel parts - during machining, particular attention must be paid to plastic deformations on the workpiece.

High-alloy steels include carbon steels with an alloy content of up to 5%. The higher the carbon content and the harder the material, the worse the machinability. This requires tools with high resistance to deformation and stable cutting edges.

Turning stainless steel

Manufacturing turned stainless steel parts is generally not an easy task. The machinability of stainless steels is strongly dependent on the alloy content used. Many common stainless steels exhibit increased mechanical stability, which causes high temperatures on the cutting surface when turning stainless steel. When turning stainless steel, the use of special cooling lubricants is therefore unavoidable. Small adjustment angles on the cutting edge of the tool reduce the burrs that would otherwise occur. The high cutting forces that occur when turning stainless steel necessitate a tool with high cutting edge stability. If the parameters are not set carefully, it is predominantly the surface of the stainless steel turned parts which suffers.

Turning brass

Brass turning parts

Brass is an alloy of copper and zinc. If you want to manufacture brass turning parts, it is very important to know the composition of the workpiece. Machining brass, an alloy of copper, zinc and a small lead content, is considered optimal for machining. This type of brass is good for hot forming and has limited cold forming properties. For best machinability, CuZn39Pb2 grade should be used for turning brass - when used with automatic lathes, CuZn39Pb3 grade is ideally suited due to its slightly higher lead content. However, care must be taken to ensure sufficient chip protection. Brass is a short-chipping material; when turning brass parts, the short chips "spray" in all directions.

Turning other metals

In addition to the most common materials, many other metals and metal alloys are machined in modern production. Copper turned parts, bronze turned parts or titanium turned parts can be found in the most diverse areas of application and have their own requirements for the manufacturing process.  

In the past, lead was used in copper turning to improve machining. Lead ensures good chip breakage and has a lubricating effect. Unfortunately, lead is also harmful to health and is therefore rarely used as an alloying component. As a result, the machinability and process reliability of copper is significantly worse. Improved tool geometries are currently being used to improve the machinability of copper even without any lead content. When turning, bronze behaves similarly to brass. Bronze is usually machined without cooling lubricants, so machining is done "dry". High speed steel or carbide tools are preferred for machining bronze.

Machining titanium on a lathe is a highly demanding task, because titanium is a metal with many peculiarities. One of the material’s special features is that it is strain-hardening, which makes machining considerably more difficult.  

Conventional turning tools soon become blunt when turning titanium, so turning tools or indexable inserts are required which have an even greater hardness than the titanium workpiece.  

Care must be taken when handling titanium chips: the chips are highly flammable and can quickly set an entire workshop on fire. Therefore, it’s very important to always use cooling lubricants when machining titanium.

Plastic turned parts

Plastic turned parts have become an indispensable part of the modern world - even if in very few cases they are directly noticeable. Plastic turned parts are used as connecting elements in mechanical engineering, as spacers in crafts or as guide bushings, sealing rings, rollers or spring adjusters

 in a wide variety of industries worldwide. To an even greater extent than the processing of metal parts, plastic turning requires the use of special tools. The reason for this lies in the large variety of plastics, each with their own very different cutting behavior.

Turning plastics

Engineering plastics such as polyamide (PA), polyethylene terephthalate (PET) or polyoxymethylene (POM) are just three of the many engineering plastics that are machined on lathes. Each plastic has its own specific requirements for the tool and the machining strategy. 

In particular, the geometry of the cutting edge on the turning tool is of the utmost importance for clean surfaces when machining plastics. Only extremely sharp tools with an optimized cutting surface allow the plastic chips to flow "cleanly" off the workpiece. When turning plastic, it is essential to ensure continuous lubrication of the workpiece and tool with sufficient coolant. Since plastics exhibit localized melting at low temperatures, an incorrect or insufficient supply of coolant can lead to the destruction of the workpiece or damage to the machine! If flexible turned parts are manufactured from plastic, the use of steady rests is recommended. These steady rests support the workpiece between the chuck and the tailstock, reliably preventing deflection and therefore an incorrect contour.
