Fully integrated CAD/CAM/CNC process chain for manufacturing

CNC solutions designed specifically for the medical industry feature the Sinumerik 840D sl CNC, the Sinamics S120 drive system, and high performance motors, all enabling machine tool users to create CAD/CAM data with NX CAM, as well as a system platform for high-speed cutting.

The manufacturing of medical implants and prostheses requires, above all, high-precision machining with a short machining time that must produce perfect surfaces. Such high precision, high-speed cutting relies on an integrated, high-performance CNC solution, covering the creation of CAD/CAM data, straightforward programming, set-up on the CNC, suitable probes, and high-precision milling with innovative tools.

High-speed cutting is technically very demanding, precisely because of the high speeds involved. Siemens CNC solutions for these types of milling tasks have correspondingly high spindle speeds and feedrates. These features are essential for the manufacturing of high-quality medical products, such as tooth and bone implants, bone screws, and hip prostheses. The interactions between its many and varied functions enables Sinumerik to be adapted, flexibly, to meet the changing demands of CNC production. These functions include the exact measurement and calibration of multi-axes kinematics and the coupled motion of the tool orientation. Innovative technologies enable medical engineering products matching precisely to a patient’s individual requirements.

In order to enable manufacturers to react quickly and easily to changing market needs, as well as increases in batch production, Siemens is offering a wide range of setup functions for machine retrofit. All the important tool-related data is saved and can be recalled later in a single step. Jerk limitation, pre-control, and the perfected look ahead function all support the operator during toolmaking and moldmaking. Sinumerik Safety Integrated also facilitates the implementation of highly effective operator and machine protection concepts.


Sinamics S120
Optimized to handle virtually any drive need, Sinamics S120 covers vector, servo, and V/Hz applications with a single product. Its modular design, system architecture, broad range of communication options, cooling concepts, safety integrated functions, and plug-and-play technology make Sinamics S120 the most advanced motion drive on the market. Designed for user-friendly global use and fast commissioning, some of the benefits of the Sinamics S120 include:

• Wide power range – from 0.25hp to 1,600hp;
• Highly scalable solutions and easy expansion through a modular design;
• Increased productivity through integrated drive safety;
• Convenient operation and programming;
• Automatic configuration of drive system and simple cabling; and
• Faster engineering and commissioning via the graphics-based SIZER and STARTER software tools.

Sinumerik 840D
Delivering accuracy, precision, and performance, the Sinumerik 840D solution line is a distributed, scalable, open, and inter-connecting control system that offers a wide range of functions. Features include:
