Customized Solutions for Specialized Requirements
URMA experts develop and manufacture precision tools tailored to your specific requirements. For challenging applications, custom tool geometries are designed to meet your needs. Each solution is precisely adapted to your machining task, workpiece material, and production conditions.
Precision Machining of Complex Bores
Modern manufacturing presents companies with increasingly demanding challenges. Tight tolerances, complex geometries with heavy interruptions, and specific surface finish requirements make precision machining more challenging. Selecting the right tool and machining strategy is essential to ensuring efficiency and quality.
In addition to meeting specified tolerances with precision, URMA solutions enable efficient machining under the most challenging conditions – whether dealing with interrupted cuts, hard materials, or demanding surface finish requirements.
Special Tools
Although our highly flexible standard reaming programs cover a wide range of applications, special tooling solutions offer significant advantages for high-volume production and highly complex machining requirements.
Our many years of experience in precision bore machining, combined with innovative out-of-the-box thinking, have helped turn many seemingly “impossible” machining tasks into success stories with the right Special Tools.
Sustainable and Efficient
Through targeted tool reconditioning, URMA extends tool life and reduces the need for new tool production. This not only saves resources and energy but also significantly reduces waste. The result: precision and performance are maintained while supporting more sustainable manufacturing practices.
URMA’s commitment to sustainability is reflected in various areas of our work. We focus on innovative approaches to reducing our environmental impact.
while ensuring product efficiency and durability. By resharpening cutting edges and reconditioning your tools, URMA promotes the responsible use of materials. From selecting high-quality raw materials to optimizing resource utilization during production, URMA is committed to sustainable manufacturing. Thanks to its well-engineered tool design, URMA minimizes the use of rare raw materials and cemented carbide.
To promote environmental awareness and social responsibility throughout its supply chain, URMA uses IntegrityNext, a leading platform for monitoring sustainability and compliance in procurement. This enables URMA to ensure that its suppliers comply with global ESG (Environmental, Social, and Governance) standards.
S.M.A.G. App
The URMA S.M.A.G. App – Smart Machining Application Guide – makes using our tools easier and more efficient. In addition to a reliable cutting data calculator, the app includes our products along with relevant formulas and tables. It helps you select the optimal RX reaming blade based on your input parameters.
