3.0 Grinding device for clamping device
The
grinding unit for the clamping device can be removed and can also be used on
other machines.
It
stands on an adjustable base plate installed under the floor. The opening is
covered during normal operation.
The
motorized grinding unit equipped with a cup grinding wheel can be adjusted in 2
axes using 2 slide units and an intermediate stand.
Adjustment
is carried out manually via fine adjustment spindles.
When
grinding the clamping device, the circular dividing table rotates at a constant
speed.
Grinding
is a manual process.
Diameter,
axial run-out and concentricity are checked with the measuring device in
station 4.
Pos.
4.0 Coolant system/chip disposal
A
generously dimensioned chip and coolant channel runs around the circular
dividing table.
It
is interrupted in the area of unit 1 and feeds coolant and chips into the
central system or onto the chip conveyor.
The
chip conveyor integrated into the intermediate piece between unit 1 and the
circular dividing table substructure is connected to an intermediate tank.
A
float switch-controlled lifting pump pumps the coolant into the paper belt
filter system, which is attached to the main tank.
The
paper belt filter system is equipped with an automatic paper transport
controlled by a float switch. Eine separate Anlage hält das Kühlmittel auf konstanter Temperatur.
Dazu wird das Kühlmittel im Hauptbehälter umgewälzt. Zum Temperaturausgleich
der Gesamtanlage sollte immer eine größere Menge Kühlmittel im Umlauf sein.
Total coolant volume 1.200
l
High-pressure pump for unit 1 60
l/min 10 bar
Low-pressure pump for units 2+3 40
l/min 2 bar
Flushing pump 200
l/min 0.2 bar
The pressure of the high-pressure pump is monitored.
A rinsing hose for cleaning the workpiece and clamping device is
available.
