Switching On The Machine; Quick Adjustment Of The Support; Switching On The Automatic Feed; Moving The Turning Tool (Longitudinal And Lateral Turning) - Proxxon PD 400 Manual De Uso

Switching on the machine

1. Set direction switch 1 (Fig. 2) to "0".
2. Disengage the leadscrew (turn leadscrew switch 2 to the
left).
3. Set a low speed (stepper switch 3 to I).
4. Switch on the machine at the main switch 4. The function
display 5 now lights.
5. Turn the direction switch to the right. The lathe chuck now
rotates in the working direction.

Quick adjustment of the support

The support can be quickly moved via handwheel 1 (Fig. 3).
For this purpose, the support must first be disengaged.
Loosen clamping screw 2 by half a turn beforehand.
1. Push lever 3 upwards.
2. Adjust the support by turning handwheel 1
(1 revolution = 10.5 mm)

Switching on the automatic feed

1. Set machine to "0" at direction switch 1 (Fig. 2)
2. Disengage support (push lever 3 (Fig. 3) upwards).
3. Ensure that handwheel 10 (Fig. 1) moves freely because it
moves the leadscrew when engaged.
4. Engage leadscrew (turn leadscrew switch 2 (Fig. 2) to the
right).
5. Switch machine on by setting direction switch to the right.
The leadscrew and the handwheel now also turn.
The automatic feed is not equipped with an automatic cut-off.
Ensure that you disengage the support before it runs against
the lathe chuck.
6. Engage support (push lever 3 (Fig. 3) downwards). The sup-
port now moves in the working direction.

Moving the turning tool
(longitudinal turning and lateral turning)
Apart from the quick adjustment of the support and the auto-
matic feed, the turning tool can be moved in 3 different ways.
A. Movement with the leadscrew (longitudinal turning)
1. Disengage leadscrew (turn leadscrew switch 2 (Fig. 2) to
the left).
2. Engage support (push lever 3 (Fig. 3) downwards).
3. Move support using the handwheel 10 (Fig. 1).
1 turn = 1.5 mm
B. Movement of the top slide (longitudinal turning)
1. If required, clamp the support (tighten screw 2 (Fig. 3)).
2. Move top slide with handwheel 4.
1 turn = 1.0 mm.
C. Moving the cross-slide (face turning)
1. If required, clamp the support (tighten screw 2).
2. Move cross-slide with handwheel 5.
1 turn = 1 mm feed = 2 mm change in diameter.
