PVD coatings for solid carbides are supplied to the market under the brand name Balinit Aldura. This coating combines the many advantages of a reliable coating system. The advantages obtained thereby can be confirmed not only by comparison tests with existing standard coatings on the market, but also by the fact that significantly higher cutting amounts can be used.
Micro-tools: For this micro-tool, the PVD coating plays a role in maintaining high circular runout accuracy and shape accuracy during the milling of the pattern.
Coating properties:
â—†Underlying coating TiAlN (aluminum nitride titanium)
Fast hard milling: The combination of a tempered mill and a Balinit-Aldura coating greatly increases mechanical load carrying capacity, wear resistance and edge strength, as well as reduced cutting forces. This significantly increases tool durability and maximizes the reliability of the process during high-speed hard milling.
â—†Functional coating based on AlCrN (aluminum oxynitride) â—†Microhardness (HV0.05): 3300
◆Maximum applicable temperature: >1100°C
User benefits:
â—†Good wear resistance â—†High mechanical load capacity â—†Excellent blade strength â—†Reduced cutting force These are also confirmed by the user. The Zecha Hard Tool Manufacturing Company, based in Konigsbach-Stein, is a manufacturer of solid carbide small tooling, which builds small tooling on the coating's outstanding adhesion properties and The higher toughness of the coating and the higher mechanical load carrying capacity. For the enterprise, the absolute accuracy of the tool, the accuracy of the circular runout and its diameter accuracy and shape accuracy are absolutely necessary in order to achieve the required quality standards. For example, a coating such as Balinit Aldura can be adapted to a specific tool geometry, so that it is possible to achieve higher tool durability and higher process reliability.
High endurance at high speeds Stefan Zecha, a Zecha shareholder, says that the partnership with Oerlikon Balzers is the basis for high quality small tools for highly demanding customers.
In the industry, the trend toward smaller components and components is increasingly driving the further development of micro-tools for three-dimensional contouring of micron-sized patterns. Therefore, Zecha is not only engaged in the forming and processing industries and the cutting industry.
Balinit Aldura coatings have excellent high temperature hardness, above-average thermal conductivity and high oxidation resistance, especially in the case of hard materials and high cutting speeds. Tool durability.
Mr. Stefan Zecha emphasized: “Not every requirement of the user can be met by a tool in a catalog. In this respect, most of our customers' products are specially supplied, but by the same company as Oerlikon Balzers Cooperation, we have the ability to provide solutions for specific applications to ensure our customers' decisive advantages in terms of process efficiency, workpiece quality and tool durability."
US Special Tools, based in Wiperfürth, Germany, is one of the leading technology suppliers in the field of carbide and high-speed steel. With a certain international customer, the company also makes full use of high-performance coatings. Before the tool is put on the market, it can be trial-produced by the customer at the machining center.
The workpieces with a surface hardness of 60HRC have been fully fulfilled, commented by Mr. Uwe Schwiola, the managing shareholder. In the hard machining of the surface hardness of up to 60HRC, significant improvements in tool durability and very good results have been achieved. In comparing the basic performance of the best-selling quality-assured coated tools on the market, Balinit Aldura showed tool durability improvements of up to 15% in tool and mold manufacturing and in tests performed on hard cutting.
Oerlikon Balzers: Tool coatings for difficult machining situations
Today, every advance made in the manufacture of molds and tools, even if this advancement seems so small, is important. Therefore, it is obviously important to cut hardened steel parts. Oerlikon Balzers has made a contribution to optimizing machining time and improving surface quality in hard machining and high-speed machining.
