Series 80-85 LIVE CENTER WITH “LOAD DISTRIBUTION” FOR TURNING

It is a Patented system developed by FRB. It consists in having 2 axial bearings (instead of 1 as in normal live centers), with an intermediate spring between them, which divides the axial thrusts.

This condition is particularly suitable for machining with face drivers where it is necessary to operate at high axle thrusts, and also for parallel lathes applications.

This range of live centers has a very impressive application versatility. In fact they are provided with connections ranging from CM2 to CM6, furthermore, they can be supplied in different versions.

Live centers with interchangeable Centers , with 60° Integral shaft, with prolonged integral shaft and also with hard metal shaft. These cover a very wide range of needs.

Series 80-85 “HEAD CARRYING” LIVE CENTERS FOR TURNING

This range of live centers has a very impressive application versatility. In fact they are provided with connections ranging from CM2 to CM6, there is also the possibility of using the same live center replacing a large number of heads, in order to support pipes with holes from 45 to 600 mm. These cover a very wide range of needs.

SERIES 2008 LIVE CENTER FOR “HARD TURNING”.

For hard material turning, the main characteristics of a live center are that the shaft must be correctly guided, the bearings must ensure a good stiffness, that the part in contact with the piece is made of hard metal, and that the live center is of extreme precision. In the 2008 FRB live center series, the 5 bearings, 3 of which roller bearings, couple the shaft with the insert with a strong pre-load, thus ensuring the correct stiffness and precision  required for the machining.

Series 2006 LIVE CENTER FOR “HIGH ROTATING SPEEDS”.

High smoothness is the quality of the FRB live center for high speed machining.

6 precision bearings installed for high speed, necessary for machining small diameters up to 6000 rpm.

Also for this type of liver center it is possible to choose a wide range of interchangeable centersalways available in stock.

Series 81 LIVE CENTERS WITH “SPRUNG SHAFT”

This is a spring operated live center, it is designed to be applied on counter spindles and on live tooling turrets.

Since these electric axes are used only for positioning and not for a continuous thrust pressure control on the workpiece, the live center series 81 holds the piece to be machined under thrust.  Changing the shaft axial positioning it is possible to obtain increasing axial loads.

The light version is available with integral shaft, cylindrical connections and hard material; the reinforced version has the shaft with interchangeable centers applied, cylindrical connections, MC and VDI.

Series 2000 “ECOLINE” LIVE CENTERS FOR TURNING.

The live center series Ecoline is designed to fulfil the most common irrelevant needs and to give the possibility to the customer to carry out maintenance autonomously.

It is a product with an excellent quality/price ratio, available with interchangeable Center, Integral prolonged shaft and integral shaft.

The first two versions are provided with a double row ball bearing, a thrust bearing and at the end 2 needle bearings. The integral shaft version is fitted with a front roller bearing. Available in CM3, 4 and 5 versions. Even here, even if in the ecoline version, the live center is fitted with extraction nut.
