Lathe Spindle

Lathe spindles are an essential part of a lathe machine. Lathe machine spindles have found their applications on a variety of fields and industries. A lathe machine tool spindles which spins a block of material to perform various operations like cutting, sanding, drilling is known as lathe. Lathe machine tool spindle are a rotating part of the lathe or the machine and are widely used in metalworking, metal spinning, woodturning, glassworking etc. These spindles are specially designed to be used in lathes, making them suitable to perform all kids of machining tasks.


Features of lathe spindles

• Lathe spindles are often hollow.
  
  
• They have exterior threads and an interior taper on the inboard with the help of which accessories which hold the workpiece may be mounted to the spindle.
  
  
• Lathe spindles may also have exterior threads and interior taper at their outboard end, and have a handwheel or other accessory mechanism on their outboard end.
  
  
• They are powered.
  
  
• They impart motion to the workpiece.
  
  
• The spindle is driven, either by foot power or by a belt drive to a power source.
  
  
• The lathe spindles feature rigid precision bearings near the spindle nose to enhance true running.
  
  
• The spindles assure better surface quality and greater machining accuracy.
  
  
• The Lathe spindle is carefully balanced.
  
  
• The lathe spindle is usually held by tapered roller bearings

Uses of lathe spindles

• Lathe spindle has also found its applications in milling industry. In milling industry, lathe spindle is efficiently used to handle the forces encountered along the axis of rotation but also the strong side forces of a heavy turning or facing cut. With the help of this type of spindle lathe can be made to double as a perfect milling substitute.
  
  
• They are suited for machining operations involving drilling tools, micro milling and as well as engraving and fine milling.
  
  
• They are used in turning centers.
  
  
• They permit precision radial drilling, milling and tapping, therby improving and expanding overall turning center capability.
  
  
• They are also used in printing industry.
  
  
• A lathe spindle is designed to efficiently handle the forces encountered along the axis of rotation and the strong side forces of a heavy turning or facing cut.
  
  
• By hard turning the lathe spindle shafts very close to net shape, it could cut grinding time by half.

Applications of lathe spindles

• Glassworking
• Metal spinning
• Metalworking
• Ornamental turning
• Woodworking
• Watch making
• Printing machines
• Milling machines
• Drilling tool etc.
