Spindles
Hydrodynamic spindles are a very important category in the field of spindles. They are used in a variety of applications in the industry such as in boring, drilling etc. The use of hydrodynamic machine tool spindles ensure perfect machining performance and product efficiency which ultimately result in high profitability. These spindles guarantee the best quality finish especially for precision surface machining. The bearing system of hydrodynamic spindles is hydrodynamic bearing and the spindles are belt driven or high frequency or motorized or gear driven.
Features of hydrodynamic spindles
- Hydrodynamic bearings replace ball bearings in such spindles. Hydrodynamic fine-machining spindles have multi-lobe bearings.
- Another feature of the design of hydrodynamic spindles is their rugged housing with a stiff shaft.
- The external shape of the spindle can easily be adapted to fit existing machine designs and configurations.
- Most of the hydrodynamic spindles consist of several lobes permanently machined into the bearing bore. The bearings result in good centering action of the shaft, creating a defined shaft position and extremely precise shaft rotation.
- While the hydrodynamic spindle is rotating, hydrodynamic bearings have low-clearance assemblies relying on a film of oil (or air) that develops clearance and hence high startup loads must be avoided for such spindles.
- These spindles feature high stiffness and long bearing life, and recommended for fine machining and finishing.
Advantages of hydrodynamic spindles
- Cost-saving: Hydrodynamic spindles ensure high-speed rotation which help in reducing processing time. Also these fast hydrodynamic spindles now make it possible to machine and optimize the cutting of problematic materials.
- Long durability: They have a long durability compared to other spindles. The excellent oil supply to the hydrodynamic bearings provided by hydraulic oil packs ensure its long life.
- Low noise level: They offer a low noise level because the rotating shaft of the spindle is carried by an oil film.
- Damping: The pressure inside the spindle system is uniformly distributed on the oil film. Because of it they have superior damping characteristics than any other spindles.
- Machining accuracy: These spindles have a phenomenon peripheral rotation accuracy of less than 1 µm (micrometer).
