Top 6 Benefits Of Torque Motor Technology

When evaluating motors, horsepower is generally considered the primary operational feature. In the case of CNC machines, torque is the true measure of the force that drives the cutting spindle.

Think of the torque motors in CNC machines as linear motors that are “rolled” rather than “unrolled” to produce torque instead of linear force. Torque motor technology allows application of direct drive motion to the fourth and fifth axes that control spindle rotation and inclination.

What are the benefits of torque motor technology as applied to CNC machining?

Simplified Integration

Direct drive torque motors consist of two parts: an inner magnetic rotor that drives rotation and an outer stator that transmits torque via electrical coil windings. This provides a pair of advantages:

  • Less mounting volume is required, resulting in greater flexibility of placement.
  • Cables, cooling tubes and other components are easily integrated through the large central shaft.

Increased Accuracy

Thanks to the absence of belts, chains and gearboxes, direct drive motors can be attached directly to the load, preventing the effects of hysteresis.

Reduced Cost Of Ownership

Fewer parts means lower risk of breakage or malfunction. In addition, limited contact with the machine virtually eliminates wear and tear, so there’s little to no loss of performance over time.

No Backlash

A perfect match of load inertia to motor inertia is virtually impossible. The traditional goal has been a ratio somewhere from 5:1 to 10:1. Higher ratios can result in gear backlash, which causes a loss in precision.

Direct drive motors have no gearboxes, removing backlash as a factor. Some direct drive applications have been known to handle inertia ratios as high as 11,000:1.

High Torque At Low Speeds

Standard electric motors require high speed to generate high torque, which has the negative effects of reducing accuracy and increasing wear and tear. The magnetic energy used in direct drive motors lets them generate significant torque at much lower speeds.

Minimal Noise, Vibration And Torque Ripple

With fewer moving parts, direct drive motors avoid excessive vibrations and torque ripple that can affect efficiency and precision. They also produce less noise for a more pleasant shop-floor atmosphere.

If you’re looking to improve accuracy and reduce labor, five-axis CNC machines using torque motor technology will provide a positive return on investment.

Extend the Life of Your CNC Machines With These Three Tips

Photo Of A CNC Machine - CMS North AmericaWhen using the CNC machines, it is always good to conduct routine maintenance to ensure a quality output. Some companies are usually so busy serving their customers that they often overlook the need to do maintenance. However, taking the time to perform maintenance helps prevent an expensive breakdown while ensuring the machine’s maximum longevity.

1. Lubrication

Tools such as the spindles, cutters, and other moving parts are used daily. These tools are likely to break, chip, or sustain dents when they are not well maintained. The operator should identify these tools and lubricate them as often as need be. It’s also important to use the right oil or grease to prevent any possible CNC machining problems.

2. Use the Correct Speeds and Feeds

For best results, it is important to run the CNC machine while using the right speeds and feeds. It is necessary to adhere to the manufacturer’s recommendations while taking into account the material, tool’s diameter, the arrangement of inserts, and the width and depth of the cut. Nowadays, companies can use a special “feeds and speeds” calculator to make the selection easy.

3. Do Not Recut Chips

Recutting chips is harmful to the life and security of the machine. Therefore, it should be avoided at all cost. It may also lead to chip jamming and cutting edge fractures. This problem is common when milling deep pockets and cavities on vertical materials. The coolant can be set up correctly to eliminate the chips easily. Additionally, splitting a deep cut into several passes can help solve this problem.

By adhering to these simple maintenance and application tips, companies can ensure their CNC machines are running at the optimum performance while assuring a reliable production process. Inspecting the machine regularly also helps to note parts and tools that may cause potential problems in the future.

CMS Delivers Innovative CNC Features for Aerospace Manufacturing

If you’re a manufacturer of, well, just about anything for aerospace, you know the importance of precision and repeatability. Few industries are subject to stricter regulations or higher expectations. As such, manufacturing any aerospace part or component, no matter how large or small, can present significant challenges. To meet the unique needs of aerospace OEMs and parts manufacturers, CMS Industries’ CNC machining centers include numerous innovative features you won’t find anywhere else.

Mobile Bridge Structures, Guide Rails & Beams

For manufacturers of large-scale aerospace components, and/or those who want to perform multiple machining processes simultaneously, many of CMS’ CNC systems are built with large work envelopes. To ensure high dynamic properties and superior accuracy in large operating spaces, our systems include specialized mobile bridge structures, guide rails, and structural beams.

CMS Mobile Bridge Structure

High-mounted guide rails on our mobile bridges provide the CNC tools with maximum accessibility to the workpiece. They also offer excellent modularity and make a very long X-axis possible, while minimizing the mass of the system’s moving parts (i.e., the beams).

Each CNC machining center’s beam—which moves along the guide rails and carries the workhead as it operates—is constructed as a single section. The most critical moving part for precision manufacturing, these beams feature a large center distance between their Y guides; this provides exceptional torsional rigidity for the entire assembly. For optimum rigidity, the weight of the beam is also critical. Our engineers specify light, hollow structures with stringers and ribs that provide high strength with low weight. Structural dimensioning is performed via FEA (finite element analysis) to achieve the perfect balance between rigidity and weight.

Engineered for Unparalleled Accuracy & Repeatability

With large-scale CNC machining centers such as these, maintaining accuracy and repeatability can be difficult. CMS Industries’ CNC systems are specially engineered to hold their tolerances and alignment and for easy adjustment should recalibration be required.

Our machining centers’ high-mounted guide rails feature double-adjustable shoulders to help compensate for any eventual settling of the machine’s foundation under its expansive X-axes, and the beam-and-rack system includes specially-designed mechanical couplings that provide reliable motion control. To counteract thermal expansion, should such a challenge present itself, actual measurements are acquired in real time by a system of thermal probes embedded in the machine, allowing the CNC system to perform automatic compensations.

All CMS CNC machining centers include state-of-the-art interfaces, direct encoders, and CNC drives from industry-leading providers. Our proprietary software offers advanced options for high speed machining with no loss of precision, accuracy, or repeatability. All mechanical components are manufactured in-house to ensure our own high standards of quality are met.

CMS designs, engineers, and manufactures the electrospindles for our CNC machining centers. We provide numerous options to give our customers the best solution for the material(s) with which they’ll be working.

CMS’ CNC Machining & the Alfa Romeo 4C

Legendary Italian automaker Alfa Romeo designed their new 4C sports car to be their “reintroduction” to the American market. This high-performance two-seater was engineered to put the best driving technology available into the most visually striking package possible. To achieve this lofty goal, Alfa Romeo teamed with CMS and other innovative European companies.

The 4C Project

To ensure the finest performance, and to meet the high standards associated with the Alfa Romeo name, every component of the 4C must be crafted with extreme precision. Additionally, Alfa Romeo plans to produce the 4C in higher numbers than a “limited series” automobile or supercar.

The automaker recognized that CNC manufacturing, with its superior accuracy, repeatability, and quick production capabilities, was the best way to achieve these ends. And for the industry’s finest CNC machining technology, they turned to CMS.

Advanced CNC Technology for Advanced Materials Machining

The 4C benefits from a number of unique design features, including a monobloc chassis and the use of composite materials throughout. Its engine crankcase is manufactured from aluminum, which provides the strength needed in a sports car drivetrain at roughly one-third the weight of steel. Similarly, the front and rear chassis frames, which support the nose and tail of the car, are also made from aluminum. A CMS Poseidon CNC machining center is used to machine the complex geometry and precise tolerances these components required.

Alfa Romeo uses carbon fiber materials for the 4C’s main chassis to keep the car’s weight low (just over 2,000 pounds) and to provide the structural stability its high performance capabilities require. Manufactured as a single, sturdy component, this carbon fiber chassis requires numerous complex machining and finishing operations. CMS’ Ares moving bridge CNC system provides the necessary precision and versatility, along with high-speed, 5-axis performance and a large work envelope.

Seat bases and backrests, as well as several other interior components, are also made from carbon fiber. One of our compact Athena CNC systems is used for the machining and finishing of these parts, including intricate detail work. With high-speed, 5-axis capabilities and a versatile worktable setup, the Athena is ideal for fast, efficient production of smaller components.

The seats of the 4C, inspired by ergonomic race car seat designs, are constructed of polyurethane foam. Molds for this foam padding were machined with a CMS Cronus K moving bridge CNC system. Specially designed for working with aluminum, light alloys, and composite materials, the Cronus provides high-speed machining, fast working-head acceleration, and unparalleled accuracy and repeatability.
