Spindle
Accessories
The design of the spindle and the quality of the components inside the spindle are major factors that contribute to the spindle's durability and longevity. The spindle should be designed in such a manner so that features that keep chips and coolant are kept out of the spindle's bearing system, like in an air purge system and wipers that use positive lubrication pressure to protect the spindle from contaminants.
Spindles: A key to improve manufacturing productivity and machine tool performance
There is no doubt about the fact that today the manufacturing industry has become more and more globalized. Manufacturers are constantly looking for various ways and means to improve the productivity of machine tools through improved power densities, higher speeds, greater flexibility, and more multitasking of operations. One important method to achieve this is by continual innovation and improvement of spindles. Spindles play a vital role in the quality of the final product and enhances the overall productivity and efficiency of the machine tool itself. Today's spindle designs offer the manufacturers and machine builders much greater performance and reliability than ever before. Users can increase productivity in any industry by properly applying the advanced spindle technologies in specific applications. The powerful, flexible and faster machine tool spindles can reduce the number of cuts and making holes in manufacturing by half.
Performance features
To increase productivity and performance of spindles, certain features that are to considered are as follows:
- Desired spindle power both peak and continuous.
- Maximum spindle load both axial and radial.
- Minimum size and weight
- Maximum torque over a broad range of speeds
- Speed allowed
- Tooling style
- Belt driven or integral motor-spindle design
Factors considered for spindles design
Besides the above-mentioned performance features, other factors that will affect the ultimate spindle design are as follows:
- Amount of available space in the head
- Complexity
- Purpose and application
- Cost considerations
- Market demands
Cost of production plays a significant impact on the final spindle design. A very sophisticated and advanced spindle design may not be acceptable on a low-cost machine tool. As a result, an advanced machine tool design can justify the higher cost of a more complex and advanced spindle package. In fact, a fast, powerful and accurate machine tool will demand a reliable high-speed spindle system.
Benefits of spindles
Certain benefits of spindles are as follows:
- Machine tool spindles reduce the number of cuts in manufacturing by
half.
- Spindles provide position and transmit power to a tool (as in the
case of milling machines).
- They hold a rotating workpiece (as in the case of lathes).
- They hold cutting tools and spin them at high torque and speed.
- Spindles support many key machining tasks.
- Allow flexibility in cutting a variety of materials.
Uses of spindles
Spindles are used to perform variety of tasks like as follows:
- Grinding
- Milling
- Engraving
- Drilling
- Boring
- Turning
- Routing
Applications of spindles
Spindles are critical in all kinds of manufacturing and hence used in variety of industrial applications. Spindles are used to support burrs in dental drills and cutters to put together composite materials. They also make parts for pumps and compressors used in the oil and petroleum industry. Spindles are used to make the molds used to make tires for the aircraft sector, the rolls that produce sheet metal for the automotive sector, and parts for the appliance industry. So various applications of spindles are in the following sectors:
- Automobile
- Glass
- Aerospace
- Machine tool
- Engine plant units
- Metal working industry
- Plastic
- Construction etc.
