Motorized (Internal Motor)

Setco offers high-performance internal motor spindles featuring a motor integrated directly into the tool’s housing. These spindles are an excellent choice for grinding, milling, cutting, and drilling applications requiring maximum precision, such as automation.

 

The various types of motorized spindles include:

 

  • High-speed: These spindles operate at high RPMs to provide high-precision results when grinding, machining, or milling materials like aluminum and composites.
  • Low-speed: Spindles that run at lower RPMs are also available and perform well in high-torque turning, drilling, and tapping applications.
  • High torque: This spindle type delivers elevated torque at reduced speeds, making it ideal for metalworking applications involving denser materials like titanium and steel.
  • Liquid-cooled: A liquid-cooled spindle can be the best choice for high-demand, continuous-use applications. The tool’s excellent thermal stability combats the potentially damaging impact of heat.
  • Self-cooled: These air-cooled internal motor spindles perform well in light- to medium-duty tasks where water cooling is impractical or inaccessible.
  • Grinding: A high-precision grinding spindle seamlessly combines high speed with maximum precision, providing reliable dimensional accuracy.
  • Multi-axis: This spindle type can rotate or tilt beyond the primary axis. The additional flexibility is ideal for complex applications, such as machining workpieces containing multiple sides or angles.

Precision Engineering and Customization

Our extensive customization capabilities separate Setco from many other motorized spindle manufacturers. We will work closely with the customer to develop a precision-engineered product for unique or challenging manufacturing applications.

Our customization process encompasses these steps:

  • Collaboration: We will seek the customer’s input, including gathering relevant application data, to establish the desired performance criteria. We’ll also define the interface with the machine tool.
  • Preliminary design: We’ll access our catalog of thousands of drawings during the initial design phase to generate multiple potential solutions. We’ll review these ideas with the customer and create drawings based on the most promising concepts.
  • Quote: We will provide pricing for the most feasible options and submit them for approval.
  • Final design: Once we receive the customer’s order, our design engineers will develop detailed CAD models to bring the spindle concept to life.
  • Confirmation: We will confirm all calculations and conduct dynamic analysis to evaluate vibration characteristics at critical speeds.
  • Manufacturing: Setco will produce the motorized spindle at our facilities using our advanced precision manufacturing techniques.
  • Testing: Our comprehensive testing process ensures the spindle meets the customer’s performance and reliability requirements.

Benefits of High-Performance Internal Motorized Spindles

There are several benefits of using a motorized spindle in CNC machines:

  • Increased accuracy: Motorized spindles can provide precise control over speed and acceleration, improving the accuracy of cutting and machining operations.
  • Higher spindle speeds: Motorized spindles can achieve higher speeds than belt-driven spindles, allowing for faster machining and increased productivity.
  • Improved surface finish: The high spindle speeds and precise control of motorized spindles can result in a better surface finish quality on machined parts.
  • Reduced vibration and noise: Motorized spindles are typically quieter and generate less vibration than belt-driven spindles, leading to a more comfortable working environment.
  • Greater flexibility: Motorized spindles can be easily integrated with CNC machines and adapted for various machining applications, making them a versatile choice for a wide range of manufacturing needs.
  • Improved tool life: Motorized spindles can offer longer tool life due to precise control over speed and acceleration, reducing the wear and tear on tools during machining.
