From high-precision CNC turning and milling of CNC parts to further processing by means of wire EDM, laser cutting, electro polishing, gear cutting, drilling, sawing and grinding right up to heat treatment and surface coating.

You need turned parts and milled parts in highest precision for your applications? Just contact us! As a turned-and-milled parts shop with a certified quality management system, we manufacture tailor-made parts according to your quality requirements.

We provide you with comprehensive advice and support for the success of your business. By means of economic production using state-of-the-art machines, with consistently high precision and quality of your components.

Your company can rely on our many years of experience and comprehensive expertise in CNC job order production. We optimally implement your requirements and wishes in CNC machining.

At Kaiser your company will find all the processes you require for the high-precision machining of metal parts. All products are made according to the specific requirements, patterns and drawings for your company. Through appropriate post-processing, among other things by sawing, drilling, gear cutting and grinding, we ensure that your components are available ready for installation.

Competencies. Core competencies.

As your turning shop, we produce both simple and complex CNC turned parts and precision turned parts with small and large diameters from 1mm to 300mm. Our modern machinery enables the economic production of multi-spindle turned parts, plain turned parts, short turned parts, finely turned parts and chuck parts. For multi-spindle turning, we machine workpieces from the bar up to 100 mm in diameter. Our high-performance CNC multi-spindle turning and milling centre enables the simultaneous 3-sided machining of complex parts within the shortest cycle times. Each multi-spindle turning process can produce batches from 20,000 pieces, and up to 10 million pieces per year can be machined at high efficiency.

Milling is a production process within metal cutting in which the tool rotates. This differentiates milling from turning, in which the workpieces rotate around their own axis. As your shop for job milling, we produce high quality CNC milled parts up to a workpiece size of 1,000 x 800 mm. As in turning, we process a wide variety of materials such as titanium, aluminium, brass, steel, stainless steel and bronze, as well as special materials. The machining is carried out on state-of-the-art 5-axis machining centres with traversing distances of 600 mm – 450 mm – 450 mm (X-Y-Z).

With high-precision grinding, you can give the surface quality of your CNC parts the proverbial last finishing touches. Grinding facilitates a better surface quality and higher precision than when using metal-cutting procedures. At Kaiser, we offer you a wide range of grinding processes such as intermediate point grinding, internal grinding, honing and lapping for your components.

Services & materials for every need

You want to turn and mill high-quality components made of titanium, aluminium, brass, steel, stainless steel, bronze or special materials? No problem: We have the know-how, the experience and the machines to fulfil your metal subcontracting requirements by 100%. And with certified 100% quality.

Titanium has a high tensile strength with low weight, excellent corrosion resistance and biological compatibility. In many cases, titanium is used as a replacement for stainless steel when higher strength is required. This permits the wall thicknesses of components to be reduced without any loss of stability. Alternatively, the strength and stiffness of workpieces can be maximized using the same dimensions. Strain hardening is employed when machining titanium. This can have a negative effect during machining. If the friction is too great due to the low feed rate of the cutting edge, strain hardening can cause the tool to quickly dull. High-quality CNC components made of titanium require sharp tools, the right feed, ideal chip formation, and appropriate tool hardness. We produce parts from titanium for you: in top quality and cost-effectiveness.

When turning parts made of aluminium, the properties of the machined aluminium alloy are decisive. The cutting speed must also be dialled correctly. This depends among other things on the tool quality, the aluminium alloy and the properties of the lathe. High speeds are employed in the production of machined parts made of aluminium. Just as in the turning of aluminium, the strength of the material is decisive for the result. For an optimum milling result, the right aluminium alloy and the appropriate milling head are what counts. These must be adapted optimally to the cutting material. When milling aluminium, the milling cutter diameter as well as the number of cutting edges is decisive. These are adapted to the strength of the alloy. For soft aluminium materials we use single-point cutters, for medium-hard aluminium alloys we use twin-bladed tools, and for hard aluminium material we use triple-bladed tools.

Brass is an alloy of copper and zinc. Modern brass alloys contain a zinc content of several percent. Approximately 50-60 brass types are used in metal processing. This makes it possible to achieve almost all desired properties. To improve machinability, some brass types contain an additional proportion of lead. These are used as free-cutting brass or machining brass for machining of red brass and standard brass. Brass is used in sleeve bearings, bushings and shells as well as gears and fittings, etc. From a single source, Kaiser offers you the whole world of CNC parts made of brass.

The machining of steel is the most common type of metal processing. Steels with low carbon content tend to stick to the cutting edge of the blade. They form long ribbon chips that can get caught in the machine. The consequence: Low cutting forces on poor surfaces of turned parts and milled parts. At medium carbon content, adhesions are no longer of significance. The cutting forces increase, the surfaces of the turned parts and milled parts made of steel will be better, and the chips are shorter. However, wear to the tools increases. Steels with a high carbon content result in high forces and temperatures, as well as high wear and tear. Surface quality and chip breaking are good. Soft steels can be easily machined. Tempered or hardened steels result in high wear and require expensive tools made of cutting ceramics or boron nitride. Kaiser produces high-quality CNC parts for you from different steel alloys and for a wide range of applications.

CNC parts made of stainless steel offer several advantages over conventional steel. Stainless steel is wear resistant, temperature resistant, resistant to corrosion, and hygienic. The machining of stainless steel requires a high level of competence, experience and instinct. Some varieties of stainless steel have increased mechanical stability. Heat generation or coolant supply must be carefully observed here. When machining stainless steel, the smallest tool cutting edge angle is used. This prevents heavy burr formation. If high cutting forces occur, we make use of tool geometries with optimum cutting edge stability. When milling stainless steel, similar problems can occur as in stainless steel turning parts. For milling, we use stainless steel alloys with suitable mechanical stability, resistant cutting tools and special cooling liquids.

Bronze is the oldest man-made metal alloy, made of tin and copper. Tools made of bronze were already used in the 3rd millennium BC. Bronze is corrosion resistant, wear resistant and water resistant, offers good suspension and gliding properties, and has a high fatigue limit. It is often used in the production of parts for transmissions and pumps. Bronze is indispensable in mechanical engineering, and is ideal for cylinder liners, glands and highly stressed sliding connections. When machining bronze, the requirements for surface quality and hardness increase with the tin content. Kaiser produces high quality parts for you, made from suitable bronze alloys. In the quality you want.

In addition to titanium, aluminium, brass, steel, stainless steel and bronze, we machine special materials in the production of high-quality components. The machined materials include aviation steel, stainless steel, ua11n, 15-5PH and 17-4PH.
