With this the upper slide or tool slide can be adjusted under an angle. The third and upper slide, tool slide, can be replaced in any desired direction
over a distance of 70 mm and it follows every movement of all underlying slides also the chuck. On top of the tool slide a tool holder has been
installed. In this tool can be exerted to a point height of maximum 15 mm, the vertical distance to the centerline. The tool holder has a fourfold
absorption and has an indexing pin with four click points. Through this can be changed of chisel very fast without having to adjust again.
The tail stock
Fig.1
The end of the centerline is formed by the tail stock (8). The axis of the fixed and tail stock are exactly in each others extension. Depending on
the lenght of the piece of work the head can be moved over the bed and it can be fixed. With the slide bush (7), in which a center has to be
installed, the piece of work can be exerted fixed and revolving right on the centerline. If you turn back the slide bush, the center is
automatically untied. The body of the head has been divided. The upper part can be adjusted sideways with regard to the upper part by means
of adjusting screws. Through this an adjustment next to the centerline can be obtained. Normal movements in the lenght direction do not have
side ways adjustments as a consequence.
The combined transmission/starting axle
Fig.3 & 4
For a good surface quality a correct and particularly a constant rate of turnover in the longitudinal direction is important. For longer pieces of
work this is almost impossible with your hands. By closing the lock nut the support is coupled with the thread on the transmission. When the
transmission has been switched on this one has been coupled to the main shaft in his turn.
With this a coupling is made with an intermediate wheel between the drive wheel of the transmission and the drive wheel for the longitudinal
feed on the headstock. This happens because of an adjustment of the change wheel scissors, watch Fig. 3 and 4. At each rotation of the main
shaft the support will move itself over a certain distance along the bed. This distance depends on the wire haste and the chosen wheel change
on the transmission. By chosing another wheel change the star ting speed can be adapted. With thread-cutting the same happens in
principle, however with a much bigger support movement with a much lower main shaft speed. In this case a coupling has to be made with the
thread-cutting driving gear of the headstock. The positioning of the gear wheels happens by the installation of the rings on the starting axle
and intermediate wheel axle of the scissors. In this case change of the change wheel on the transmission makes possible a choice of the
haste of the thread which has to be cut. On the transmission is no automatic cut out. So switch this one off for preventing that the chisel runs
against the chuck.
The drive
Fig.5
Since the applied motor has a fixed and relatively high number of revolutions the transmission has been done in such a way that this reduces
the numbers of revolutions at the same time. Besides, with the application of plural pulleys and an intermediate pulley this number of
revolutions is variable in six successive steps. For lifting up possible belt tension differences the bearing-mounted belt pressure roll has been
made variable. Watch Fig.5. For reaching the three highest spindle speeds the front belt has to be shifted from the intermediate-pulley to the
motor pulley. The intermediate gear keeps driven and serves as flywheel for catching load variations.
Basic principles of the turning
Before you can start turning, you have to know the most important basic under standings. Otherwise there is a change that the wrong turning
speed or the wrong chisel is chosen. With a number of tables and rules making the machine ready for turning is easier.
Clamping
Fig.6 – 8
Mounting the three-chuck:
• Before mounting the three-chuck onto the flange, clean both parts
• Place the three-chuck onto the flange: the 3 screw holes of the chuck have to be in line with the holes in the flange
• Place the 3 Allen screws in the screw holes of the three-chuck (only tighten a bit)
• Tighten the Allen screws by hand (as far as possible by hand)
• Finally use the short Allen key to tighten the screws equally: Be aware the three-chuck does not pull out of position, otherwise it won’t fit!
Clamping the piece of work has to happen with care. Put the piece of work in the chuck as far as possible and clamp this one with the
tightening wrench. If you clamp too hard the chuck, basins or the piece of work can be damaged. The same applies for the sliding tube.
Tighten this one with your hands, strong but not by force. Some clamping examples by which also the use of bores and chisel is made clear,
can be seen in Fig.6, 7 and 8. The represented standard three-chuck is self-centring. Through this the axis of a small piece of work falls
exactly on the centerline, even if the dead centre is not used.
With a chuck belongs an inside basin (represented) and an outside basin. These ones are used for inside clamping of bigger diameters.
Every basin has in the chuck the same place. Place and basin are numbered! In Fig.6 a right side cutting chisel (up) and a right bended
roughing tool is used. The arrows indicate the starting direction. The roughing tool can be used in longitudinal direction and in cross direction
and is often used for quickly elimina ting many material. Fig 7. shows the use of a left side cutting chisel (up) and a blind boring chisel. Fig.8
shows a clamp with dead center in a tail stock. Apointed chisel has been used for an egal finish. Under this Figure a clamping is represen ted
for making a bore with a spiral drill. Beforehand you have to pre-drill with a center bore. This is a bore from which the shank is much thicker
than the crossing frog. The boring gap which arises through that serves as a center gap for both the center and the bore!
