MAPAL HTC Spannfutter / HTC Clamping Chuck
Warning
There are no guards on the machine.
Using the HTC clamping chuck in the machine without guards could
result in serious injuries to the operator.
When using the HTC clamping chuck all guards as per the EC Ma-
chinery directive point 1.4.2.2. must be fitted and the machine area
door must be closed.
Warning
Clamping and unclamping with the machine not stationary.
Clamping and unclamping the HTC clamping chuck with the machine
running may result in serious injuries to the fingers and hands.
Switch off the machine. Only clamp and unclamp the HTC clamping
chuck with the machine stationary or with it outside the machine.
Warning
Inadequate clamping to the stop and non-compliance with the
minimum revolutions
may cause the tool to be released at high projectile speeds, which can
cause serious injuries.
During clamping, always screw in the clamping screw to the stop in
compliance with the minimum revolutions (see section "3.2 Tech-
nical data").
Warning
By using long, cantilevered and heavy tools or extensions,
may cause the tool to be released at high projectile speeds, which can
cause serious injuries.
For long, cantilevered and heavy tools or extensions decrease the
speed according to user definition.
For special versions, note the speed of the drawing.
Warning
The spindle speed limits of the machine-side connection of the
HTC clamping chuck are not observed.
Exceeding the spindle speed limits of the machine-side connection
can cause serious injuries to the operator.
Observe the spindle speed limits (see "Table 2: Estimated spindle
speed limits for clamping chuck with HSK connection" on page 25)
for HSK connections. The user is individually responsible for de-
termining spindle speed limits for the HTC clamping chuck with
other machine-side connections.
Warning
Unclamping at high temperatures
may cause the tool to be released at high projectile speeds, which can
cause serious injuries.
Clamp and unclamp the clamping chuck only at room temperature.
