High Frequency Spindle

What is a high frequency spindle?
High-frequency spindles form a very important category of spindles designed for precision, high speed and productivity. These spindles are suitable for milling and drilling of metallic and non-metallic materials at highest speed and continuous power. They are available with different power and speed ranges and cartridge, flange cartridge, block body, base mount styles. High frequency spindles are helpful in getting better surface finish and high productivity. They have integrated motor design which eliminates gears and pulleys, and thus making it very compact. They are so called because they require separate external frequency converter.

Features of hi-frequency spindles

• Aggressive motors
  
  
• Excellent bearing rigidity
  
  
• High rotational accuracy
  
  
• Vibration-free operation
  
  
• Extreme precision
  
  
• Maximum efficiency
  
  
• High rigidity
  
  
• High-performance spindles feature various external diameters range and various tensioning systems.
  
  
• They come in a wide variety of horsepower, rpm levels and body styles.
  
  
• They are engineered for optimal reliability and long-life.
  
  
• Body styles of hi-frequency spindles can be cartridge, flange cartridge, base mounted and block style.
  
  
• In some spindles, the components feature case hardening, tempering treatments, isothermal annealing to prevent wear and loss of precision.
  
  
• High precision ball bearings to optimize the speed/bearing diameter ratio.
  
  
• Forced motor cooling
  
  
• All rotating parts in the spindle are balanced carefully before and after assembly.
  
  
• Lubrication systems are designed and optimized to obtain maximum speed in such spindles.
  
  
• Usually automatic tool change.
  
  
• Assembly in such spindles is designed to allow for easy maintenance.

Accessories for High frequency spindles

• Frequency Converter: Suitable frequency converter to assure optimum compatibility with and best performance of the hf spindles.
  
  
• Lubricating Systems, Cooling Units: Very essential in order to protect the life and performance of the spindle.
  
  
• Tool Clamping Systems: Either automatic or manual.
  
  
• Screw-in mandrels, Flanges, Collets, Arbors etc.

Other High Frequency spindles

• High Frequency Grinding Spindles
• High Frequency Milling Spindles

Uses of high-frequency spindles
High frequency spindles are recommended for those applications where high speed and high accuracy is required. These spindles relate to a technology that permits on average the highest level of performance.

Applications of high frequency spindles
Hi-frequency spindles are suitable to perform various machining tasks like

• Grinding
• Milling
• Drilling
• Engraving
  
  

They are used in applications like internal grinding of bearing races, internal thread grinding, and other bore grinding applications. They satisfy very precise milling requirements. They are used in dry-machining and high-speed-cutting applications as well.
