15.1. SAFETY BRAKE OF THE VERTICAL Z AXIS

o An electromagnetic brake is fitted on the upper end of the ball screw of the vertical

axis, which acts as a security in case of a power cut and avoids the vertical slide

falling down.

o This safety system is fitted in case of a failure in operation of the counterweight for

the vertical slide compensation.

16. COOLANT SYSTEM

§ A reservoir has been fitted on the outer end of the bed with a tank, which holds 880 litres

of coolant and a motor pump.

§ Within the tank there is an electrical coolant level switch for coolant

vigilante.

§ The coolant is pumped from the tank with a flow rate of 30 liter/min and

pressure of 4 bars to the end of the main shaft. The nozzles can be

adjusted towards the tool point, and the flow can be set by means of a

shut-off valve.

17. LUBRICATION

§ The lubrication system consists of a central unit which by means of a time delayed

signal given by the CNC automatically distributes the oil to several points such as

ball screws, to the MR type roller shoes in three axis and RUSV type roller shoes of

X axis. In order to have smooth running of the machine, all rolling elements are

lubricated.

§ The lubrication may also be set into operation manually by means of an electric push

button on the control panel.

§ Pinion and racks are lubricated from grease lubrication unit and by a felt greaser

pinion.

§ This unit has been provided with safety systems and circuit control so that

any abnormality, low oil level in tank, clogging up of piping, etc. is

immediately detected, triggering the corresponding alarm displayed on the

screen.
