GUIDE SYSTEM

A further organ very easily wearable consists of the guides of the mobile table (traverse) of the press. As a matter of fact when charges are not completely centered to the principal forging axe of the machine, then guides do wear out in a non distributed and non uniform way. Often some operations which apparently seem to be harmless do wear out the guides too early and one is compelled to stop the machine since an extraordinary maintenance has become necessary. In the traditional presses it is not always easy to replace a guide, sometimes this operation proves to be very expensive both as far as either time or money are concerned. The worst mistake which can be done in such cases is to try to go further under such conditions. The machine will start then to work bad and some other damage much more serious than the only guides' replacement or restoration might be caused.

TDS series improves considerably in this regard. Every special guide mounted in the machine is made of anti-wear steel very hard (Hardox 400) and the counter-guides present in the mobile table are made of bronze aluminum-forged, this one also is very hard. On the bronze guides some special slots with no exits are realized. They are properly fed by a suitable fat under high pressure (standard is 400 bar) and the lubrication fat by intervals programmed is pumped into the control system. Intervals are managed in a dynamic and not static way.This means that the customer will get a remarkable fat saving since the electronic system can recognise the machine actual lubrication needs. Every indepedent lubrication group is properly monitored by a contemporary screen signaling of the eventual anhomalies.

In order to easen the task of the technicians in charge of the maintenance every mechanic part concerned with the sliding guides of the machine can be adjusted externally and easily replaceable by new unified spare parts, without it being necessary to dismount big parts of the machine. That was made modular and inter-changeable without using any big lifting means. The eventual spare parts to be stocked are quite very few. The customer then can become completely self-standing and not depend from the manufacturer of the machine any more, not even for the spare parts!

The benefits which can be enjoyed immediately after the first press ordinary maintenance are enormous. By this solution it will be no more necessary to dismount big parts of the machine or to arrange for heavy revamping by machine levelling workings in order to avoid its being partially dismounted, i.e. huge saving as far as costs and time are concerned.
