In 2004 OMLAT spa studied and realised several electric spindle applications for grinding, with the technical characteristic of having hydrostatic bushes instead of ball bearings.
This concept (an oil cushion with approx. 60 bar pressure) makes it possible to obtain a dynamic rigidity that is more than three times that obtained with the mechanical solution (ball bearings) and consequently guarantees a very high quality finish.
These spindles have been constructed for tangential grinding machines, for the large size bearings sector and for the rolling cylinder grinding sector.
Both asynchronous and synchronous motors have been used able to fully meet the project requirements regarding performance (power and rotation speed), together with a very low vibration level, appropriate for high-precision machining.
With the high rigidity obtained by this system, last generation tools can be used to full advantage, ensuring the best output and long life.
Here we indicate the speed range of the hydrostatic electrospindles.
- Speed: range: from 1800 to 3000 min-1
- Power range (S1/100%): from 35 to 45 kW
- Torque (S1/100%): from 100 to 380 Nm
- Wheel: range from ø400mm to ø1000mm

Where there are extreme requirements for running precision and damping, e.g. for fine boring, fine turning or for table mountings, the use of motor spindles with plain bearings is recommended. WEISS GmbH offers a broad range of products for this, including spindle units with both hydrodynamic and hydrostatic bearings.
Thanks to their separating oil film, WEISS motor spindles with plain bearings ensure uniform machining quality over an extremely long period, in addition to maximum precision and extremely long service lives. The truths of running and axial runout precisions attainable are generally less than 1 µm. Particularly with spindles with hydrodynamic bearings, a wider speed range can be covered with the same oil viscosity due to the flexible structure of the hydrodynamic bearings (skids). |

Thanks to the study of the working cycles of different machines for aluminium, plastic, wood, composite materials and graphite working OMLAT has been able to design and build proper electrospindles for this kind of operations.
The rotation speed, the power and the torque, the tool attachment, the clamping system and the bearings are all factors that have been carefully considered with the aim to guarantee high performances and reliability of the electrospindles. |

In order to accomplish the complete processing of workpieces on a center lathe, there are machines, whose acquisition is extremely complex very expensively and programming.
Our proposal for solution aims there that with a relatively simple accessory equipment, which can be to a large extent completely finished worked on turned parts.
This accessory equipment, briefly "MILLINGFIXED" called, can both on conventional and cycle-steered center lathes, to be simply post and/or rigged.
To the temporary storage facilities of turned parts, renewed rigging to a second machine, double expenditure of time, as well as high acquisition value are allotted. Complex programming and an impaired work space are omitted likewise by the employment "MILLINGFIXED".
We are convinced of the fact that this innovative solution will be in particular for manufacturing and repair shops relating to crafts, as well as very useful for school and training. |

The retrofitting options in particular mean that the possible uses of our geared motor spindles are diverse. Most applications are in the following areas:
- Milling
- Turning
- Special applications
We are currently offering an undisputed technological lead in geared motor spindles for turning and milling at high torques. Geared motor spindles for milling are primarily used for heavy-duty machining, the machining of titanium and in shipbuilding.
Geared spindles have smaller rotating masses compared to existing assemblies with an external drive and run more quietly and with less vibration. Comparatively good machining standards are achieved for planing. While maintaining the radial dimensions and motor performance, the usable torque of the motor can be increased 4-fold. This allows considerable expansion of the machining range of a machine, particularly for rough-machining, i.e. more machining tasks can be performed with different cutting speeds (different materials) with small and larger tools. |

Modern spindle units for effective milling results
Many milling machines - both old and new - have a relatively low maximum speed does have advantages in roughing operations, but are a big drawback to achieving effective feed rates.
Low speed also greatly limits the advantages of modern CNC applications. The results: much longer machining times and loss of valuable production capacities.
We offer a concincing solution for this situation: Pokolm-Voha high-speed spindle systems for the most profitable machining results. |
