A new way to conceive the power unit of the lathe for high production and precision applications. The new technologies of manufacture of the motors allow obtaining many copies in a view lot of volumes.
As an option may be requested parking brakes, which are used to block the chuck axis either during the working or for safety purposes, when the operator replaces the worked piece.
To guarantee the best results of cooling and homogeneity of the structures we use the technology of the cooling lead-in on the outside of the motor.

The Delta Line presented in this catalogue includes electrospindles for high speed milling operations that represent one of the best products available on the world market.
OMLAT has developed this line of electrospindles following the needs of tool machine manufacturers and paying particular attention to the reliability of the products.
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. |

The high speed spindles and electrospindles designed and manufactured by OMLAT are an example of innovation and technical precision from 50 years. This is a consolidated tradition and the basis to establish a relationship of trust with lots of partner companies whose success is a great satisfaction for OMLAT.
The technology of the electrospindle has recently spread over a lot of fields where high speed cutting operations are necessary to spare time, to reduce the costs and to guarantee perfect results and reliability (Wood working, plastic, aluminium, glass, graphite and composite materials). Omlat with its "know-how" is able to follow this continuous technical evolution and to offer spindles and electrospindles for all working operations requiring power, speed, stiffness and application.
OMLAT spindles and electrospindles are a sample of tecnology and precision, a good solution for high quality results.

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. |

Self Cooled electrospindle: what does it mean?
It means that OMLAT has studied and realized a new product starting from the electrospindles of the world known and world appreciated Delat line and adding a very important innovation.
there is no cooling system for the electric motor of the electrospindle, neither water cooling nor air cooling. This type of electrospindle can be installed and used very easily and it suited for applications where the working cycles must not be very long, even if the electrospindle is used for 24 hours per day.
The internal structure of this new product is the same as the strusture of the water cooled DELTA electrospindles, but it is equipped with a special electric motor that is proper for this use. thanks to the combination of these characteristics OMLAT has created a new type of electrospindle that is cheap and can be easily used, but at the same time it maintains the power, the speed and the reliability of all OMLAT products. |

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

They are used for special machining on vertical and horizontal spindle grinding machines (i.e. dovetails, slideways, diets etc..). Surface grinding machines (next to the main spindle), milling-planing machines or transfer machines are often equipped with these electroheads.
Great powers are then used on surface grinders (face grinding with segmental wheels).
|
|
No more than 15 years ago they were used to equip special-purpose grinders, while nowadays they are often included in the standard equipment of general-purpose grinders thanks also to the remarkable versatility in electronics.
Electrospindles are largely used in mass-production; in fact, manufacturers of bearings, ball and socket joints, injectors and pumps are all great users of this component.
In addition, the automation in wheel replacement has markedly increased their use.

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).

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. |
