Overview
TDM SA is a leading company in the design, development, and manufacturing of high-speed precision motor spindles, known for their reduced vibrations, less heating, increased speed, and enhanced rigidity. The company is based in Switzerland and offers a range of compact and efficient motor spindles that can be integrated into various machine tools.

Product Features
The TDM Multi-Tools motor spindles are designed to increase the capabilities of machines by offering a rational and economic solution. These spindles are compact, available in several standard sizes, and can be easily integrated into machine working areas. They support multiple tools, significantly enhancing machining possibilities.

Performance and Applications
The electrospindles are fully sealed, dynamic, and can reach speeds of 80,000 rpm or more, depending on the model. They are suitable for grinding, high precision turning, and milling operations. The tool change is rapid, occurring in 1 to 2 seconds. The spindles are designed for optimal working conditions with options like threaded holes, through-center cooling, and various sensors.

Design and Customization
The robust design ensures the selected tool is in direct contact with the motorspindle, eliminating the need for clutches or gears. The toolholder is inserted directly into the spindle shaft via an HSK interface, reducing vibrations and extending the life of tools and bearings.

Models and Specifications
The document lists several models of motor spindles, each with different specifications:

• MT 11 HSK 11: Up to 80,000 rpm, 0.3 Nm torque, 2 kW power
• MT 25 HSK 25: Up to 60,000 rpm, 1.2 Nm torque, 3 kW power
• MT 32 HSK 32: Up to 45,000 rpm, 8 Nm torque, 7 kW power
• MT 40 HSK 40: Up to 40,000 rpm, 14.3 Nm torque, 15 kW power
• MT 50 HSK 50: Up to 30,000 rpm, 30 Nm torque, 25 kW power
• MT 63 HSK 63: Up to 24,000 rpm, 60 Nm torque, 30 kW power

These models are ideal for turning machines, milling centers, grinding machines, and transfer machines, with tool interfaces ranging from HSK 11 to HSK 63 and tool numbers from 4 to 30.

Availability and Support
The MULTI-TOOLS spindles are available for new machine-tool manufacturers and as retrofit sets for existing machines. Additional documentation is available for various operations, including milling and grinding, along with support units like cooling systems, frequency converters, and lubrication units.
