RENAUD TECHNOLOGY

On the basis of standard range or in the case of the development of a new project our engineering and design department can integrate in our products various technologies, basic or of point, in order to provide to our customers spindle answering their desires and offering a maximum effectiveness.

The form

Renaud produces spindle with specific dimensions, whether is of cylindrical or parallelepipedic form with fixing with flange, by foot or others. We also produce spindle, with particular materials, being able to work in highly aggressive medium.

The bearings

Our spindle can be equipped with high precision bearings with preload :

fixed

Elastic

hydraulics

With system of lubrication :

with grease (with life)

minimal air-oil

minimal oil (injection by the external ring)

The interface of tooling systems, respectively of toolholder

We make interfaces :

standards, like : HSK according to DIN 69893, ISO tapper according to DIN 69871, MAS 403, ANSI B5.50, collets of SCHAUBLIN company or others
special according to the data of the customer

With clamping :

manual
automatic

Unclamping :

pneumatic
hydraulic
by external action

Drive

Our spindle can be pulled by an external element, such as for example under the action of a belt.

Or our electrospindle, offering characteristics power - torque according to speed corresponding perfectly to the need for our customers, drived by :

normalized motor which can be equipped with :

- simple ventilation

- forced ventilation

- brake

HF motor integrated of technology :

with cooling of the type :

- asynchronous

- synchronous

- liquid

- by air

- natural convection

Being able to be equipped with thermistor of the type PTC or others.

Protection in dirty environement

Our spindle can be equipped with :

cleaning of the tapper and/or the face by compressed air

simple effect air seal at the spindle nose

effective air seal at the spindle nose (immersed environement)

Data acquisition

Our spindle can be equipped with :

sensor « spindle stop »
angular encoder for positioning of the shaft
position sensor of tool clamping :    - clamped
                                                    - unclamped

                                                   - at rest

measurement and compensation system of the dilation
temperature measurement of the bearings in front and/or behind
vibration sensor
integrated system of self-balancing
tool - part contact sensor
power sensor
static force sensor
dynamic force sensor

Integrated mechanical technology

Our spindle can be equipped with :

Brake :

pneumatic
hydraulic
electromagnetic

Indexing :

manual

pneumatic

hydraulic

electromagnetic

Cooling system

Our spindle can be equipped with :

cooling by the shaft :

auxiliary cooling nozzles

- with high pressure by rotary union

- for high speed spindle by rotary union

without contact
