TECHNICAL SPECIFICATIONS OF PARTS
BEARING
The electrospindle uses a pair of radial angular contact ball bearings on front, the bearing diameter is
40mm.
Bearings have been permanently lubricated and require no the addition of lubricants.
TOOL HOLDER LOCKING AND RELEASING DEVICE
The tool-holder is mechanically blocked with elastic springs. The axial force for tool holder is 3500N + 10%.
The blocking and expulsion of the tool-holder is carried out by the single-acting movement of a pneumatic
piston, activated with compressed air. The pneumatic piston works under the pressure of 7bar (100PSI).
The axial force exerted on the tool-holder by the blocking system is guaranteed
constant for a minimum duration of 2,000,000 cycles of tool change
One time of tool cycle = tool lock / tool release / tool lock
CLEANING THE TOOL-HOLDER CONE AND INTERNAL
PRESSURISATION
The air jet for cleaning the cone is automatically activated during the tool change phase. This procedure
protects the coupling surfaces against deposits of contaminants. The condition of the connecting surfaces
and their degree of cleanliness must be checked at regular intervals
The pneumatic circuit of internal pressurisation prevents harmful particles from entering the electrospindle.
The air introduced finds an outlet through the gaps of the front labyrinth in the area of the electrospindle
nose. The required air pressure is 4bar.
Pressurization air must always be present, even when the electrospindle is stopped
and the machine switched on. It must also be present during machine maintenance
and cleaning operations, to prevent dust from getting inside.
