During operation, individual machine components will exceed these
temperatures.
During normal use, the temperature of the machine housing normally increases to
about 25
o
F (14
o
C) above the ambient temperature. It is good practice to make critical
final machining cuts after the machine has been running continuously for at least 15
minutes.
Machining metal raises the temperature of machine components and can
generate hot chips that burn. Use caution when changing inserts and
handling or adjusting the cutting tool after use.
The suggested HPU oil temperature for AW32 is 27–155
o
F (-3–68
o
C).

The suggested HPU oil temperature for AW46 is 39–172
o
F (4–78
o
C).
2.4.2 Pressure
For the pneumatic machine, the recommended air pressure is 90 psi (6.2 bar) at
65 CFM.
For the hydraulic machine:
• The flow rate should not exceed 10gal/min (38l/min).
• The pressure should not exceed 2,200psi (152 bar).
2.4.3 Rotational speed
For the pneumatic machine, the operational rotating speed is 1–35 RPM.
For the hydraulic machine, the operational rotating speed is 3.5–37 RPM.
2.4.4 Feed rate
The feed is pneumatically powered and is controlled by the rotation of the machine.
The feed rate is not remotely adjustable and should be adjusted at the feed box as
described in Section 3.12.1 on page 49.
The allowable air pressure for the feed mechanism is 30–100 psi (2–6.9 bar).

mendation for oil temperature.
