Working area
The conditions for workpiece chucking.
In general.
No workpiece clamping devices are controllable if the spindle is rotating. Work clamping device is equipped with a
protective shield for supplying of EN 293 requirements.
Programm will not run in operating mode sooner until the following conditions are fulfilled:
a) max. spindle speed for machining every rebound is set and displayed
b) the max. admissible revolutions of lathe chucking device are preselected.
c) the power applied on the tailstock sleeve is checked.
Manual device
There are means which can stop the spindle starting if a wrench is pushed into the chuck or a crank into the face-plate.
Throwing up
Working area is covered with a protective shield which minimalizes to throw workpieces, machine components, tools or
their parts, chips and cutting lubricant up.
Approach to the working area
To avoid acting risk factors mentioned in EN 292-1, the article 4.2 (drawing in, clamping, cut, etc.) there is a limitation of
approach to the dangerous parts, for example rotating chuck (chucks), face-plate and spindle (spindles) power operated
tools, moving parts of lathe in coordinate axes and drives, by means of a protective shield. The protective shield prevents
from approaching to the working area and also serves as a shield which minimalizes a risk of throwing up.
Drives protection
Drives ( for example indented belt drive) are covered with fast protective shield.
Blocking with protective shields
Moving protective shields which prevent an approach to the dangerous spaces of lathe motions are equipped with blocking
devices. The selection of blocking device is in accordance with EN 1088, the article 7.1.. The blocking error causes the lathe
stop -see 1 cathegory according to EN 60204-1, the article 9.2.2..
Blocking device with locking of protective shield (see EN1088 and EN999). Moving protective shields will keep clossed in
operating mode until the lathe stops. The other safety devices and means as limited spindle speed are in function of
adjusting mode.
Demanded characteristics of protective shields
In general.
Protective shields fulfil the EN 953 Standard.
Protective power - operated shields
Protective power - operated shields are in accordance with EN 292-2, the article 4.2.2.6..
