Titanium offers high tensile strength with low weight, excellent corrosion resistance, and biocompatibility. In many cases, titanium is used as a substitute for stainless steel when higher strength is required. This allows for reducing the wall thickness of components while maintaining the same stability. Alternatively, the strength and stiffness of workpieces can be maximized with the same dimensions. Various milling processes can be applied during machining. Precision turning or milling can result in a phenomenon called cold hardening, which can be disruptive. If the friction becomes too high due to insufficient feed of the cutting edge, cold hardening can cause the tool to dull quickly. High-quality CNC parts made of titanium require sharp tools with the right hardness, feed, and optimal chip formation. We take care of the part manufacturing for you: in top quality and cost-effectiveness.

For turned parts made of aluminum, the properties of the alloy being machined are crucial. The cutting speed must also be chosen correctly, depending on factors such as tool quality, alloy, and the characteristics of the lathe. In the production of milled parts using modern milling processes, high speeds are utilized. Just like in turning aluminum, the strength of the material determines the outcome of milling operations. For an optimal milling result, the right aluminum alloy and the appropriate milling head are essential. The milling head must be perfectly matched to the material being machined. The key factors in milling aluminum are the cutter diameter and the number of cutting edges, which are adjusted to the strength of the aluminum alloy. For soft aluminum, we use single-cutters, for medium-hard alloys, double-cutters, and for hard aluminum materials, triple-cutters.

Brass is an alloy of copper and zinc, with modern alloys containing a zinc content of several percent. In metalworking, around 50-60 varieties of brass are used, allowing for the achievement of almost any desired properties. Some types receive additional lead content for better machinability. Brass is used in applications such as sliding bearings, bushings, shells, gears, and fittings. Precision parts, automatic and long-turned parts: Kaiser offers you the entire world of CNC parts made from this alloy all in one place.

Machining steel is the most widely used form of metalworking. Whether drilling or grinding, turning or milling: steel is generally suitable for any machining technique. Low-carbon steels tend to stick to the cutting edge, forming long ribbon chips that can get entangled in the machine. The result is low cutting forces with poor surfaces of turned and milled parts. With medium carbon content, sticking is not an issue. Cutting forces increase, the surfaces of turned and milled parts made of steel improve, and the chips become shorter. However, tool wear increases. High-carbon content steels lead to high forces and temperatures, as well as high wear. Surface quality and chip breakage are good. Soft steels are easy to machine. Quenched or hardened steels result in high wear and require expensive tools made of cutting ceramic or boron nitride. Free-cutting steel is optimized for automated machining processes and is ideal for drilling and turning and milling operations. Due to its good machinability, free-cutting steel is optimal for automatic lathes, milling machines, and large production runs. Kaiser manufactures high-quality CNC parts from various steel alloys for various applications.

CNC parts made of stainless steel offer various advantages over conventional steel. Stainless steel is wear-resistant, temperature-resistant, corrosion-resistant, and hygienic. It allows for the realization of the smallest precision parts as well as complex geometries with cavities, bores, etc. Bars and profiles can be machined on up to 5 axes.

Machining stainless steel requires a high level of competence, experience, and sensitivity. Some stainless steel types exhibit increased mechanical stability, requiring attention to heat generation and coolant supply. When machining stainless steel, minimal cutting angles are used to avoid significant burr formation. If high cutting forces occur, we use tool geometries with optimal cutting edge stability. Similar problems may arise when milling stainless steel compared to stainless steel turned parts. For milling, we use stainless steel alloys with suitable mechanical stability, resistant cutting tools, and special cooling fluids

Bronze is the oldest metal alloy made by humans, consisting of tin and copper. Tools made of bronze were already used in the 3rd millennium BC. The alloy is corrosion-resistant, wear-resistant, water-resistant, offers good spring and sliding properties, and has high fatigue strength. It is well-suited for the manufacturing processes of machining technology and is frequently used for parts in gears and pumps. In mechanical engineering, it is indispensable and ideal for cylinder liners, packing bushings, and highly stressed sliding connections. With an increase in tin content, the requirements for surface quality and hardness also rise during machining. Kaiser manufactures high-quality parts from suitable bronze alloys, meeting the quality you desire.

In addition to titanium, aluminum, brass, steel, stainless steel, and bronze, we machine special materials to produce high-quality components. Machined materials include aviation steel, Nirosta, ua11n, 15-5PH, and 17-4PH, among others
