Machine tools for complete machining
What is meant by “complete machining”?
In the modern manufacturing industry, the term “complete machining” refers to a particularly efficient manufacturing concept in which a workpiece is fully machined with as few setups as possible. The goal is to perform all necessary machining steps—such as turning, milling, drilling, threading, or grinding — on a single machine tool or within an automated manufacturing system. This eliminates time-consuming workpiece changes between different machines, which significantly boosts productivity and improves machining accuracy, since every clamping and unclamping operation involves dimensional deviations.
The machining process in complete machining is usually carried out on state-of-the-art CNC-controlled machines, such as turning-milling centers or multi-axis machining centers. The raw part is clamped once, or in the case of turning-milling machines, is occasionally transferred automatically for rear-side machining directly from the main spindle to the Counter spindle, and then undergoes various machining processes in a precisely defined sequence. Tool changers and automated controls ensure that the appropriate tools are used with precision. Through simultaneous movements in multiple axes, even complex geometries can be produced in a single manufacturing cycle.
Advantages of complete machining
A key advantage of CNC complete machining lies in its high dimensional accuracy and repeatability. Since the workpiece remains in the same clamping position throughout the entire process, positioning errors and tolerance deviations are significantly reduced. At the same time, the risk of damage caused by manual re-clamping or transport between different machines is minimized.
Furthermore, complete machining contributes to the optimization of manufacturing costs. Setup times are minimized, cycle times are shortened, inventories of partially machined workpieces are avoided, and the need for personnel and logistics is reduced. This process has become particularly established in series production and for complex components, such as in the automotive, aerospace, or medical technology industries.
By combining multiple machining steps into a single integrated process, complete machining is a central component of modern, automated production strategies and enables cost-effective, high-quality metal machining.

Which metals are suitable for CNC complete machining?
A wide range of metals are processed in complete machining, including primarily steel, stainless steel, aluminum, cast iron, copper, and brass. High-strength materials such as titanium or nickel-based alloys are also used. The choice of metal depends on requirements such as strength, corrosion resistance, and the intended application of the workpiece.
Applications in industrial metalworking
Machine tools for complete machining are particularly relevant in the automotive industry, aerospace, medical technology, mechanical engineering, energy technology, and in tool and mold making. Precision engineering and plant construction also benefit from the high precision and efficiency of this manufacturing technology.
Typical workpieces and machining operations in complete machining are diverse. For example, crankshafts are manufactured through turning, milling, and drilling. Gear shafts are produced through turning, gear manufacturing, and thread cutting. Valve housings are manufactured through milling, drilling, and reaming. In medical technology, implants are produced through turning, milling, and fine grinding.
Other examples include hydraulic blocks, which are produced by milling, drilling, and thread cutting, as well as turbine blades, which involve complex 5-axis milling operations and grinding processes. Spindles are manufactured by turning, grinding, and drilling, while clutch components are produced by turning, milling, and drilling.
Housing parts for electric motors are also manufactured through milling, drilling, and thread cutting. Tool interfaces are produced through turning, milling, and grinding. Finally, precision bushings are manufactured through turning, drilling, and honing.
Tools for Complete Machining Centers
A wide variety of highly specialized cutting tools are used in complete machining centers to cover different machining steps. Among the most important are turning tools for external and internal machining, as well as milling cutters such as end mills, face mills, and ball-end mills for complex contours. For drilling, twist drills, deep-hole drills, and center drills are used.
Other important tools include taps and thread milling cutters for producing internal and external threads. Reamers ensure precise fits, while countersinks are used for clean chamfers and countersinks. In addition, grooving tools, form tools, and grinding tools are used to achieve complex geometries and high surface finishes.
