Using This Manual
The following pages contain recommended Tornos Multi-Spindle set-up procedures
common to most standard job changeovers, with some additional guidelines
on setting up more difficult and complex jobs.
Tool set-up instructions are shown on the left pages and a tool data sheet is on the right.
These sheets are presented in a chronological order of a typical set-up.
The set-up trainee should first read the recommended steps, then proceed to complete
each set of steps in their recommended order.
Usually, when a new set-up is required, an old set-up must first be broken down. Before
doing this, Always compare the new product layout sheet with the layout sheet of the job now
running in the machine, remove all appropriate cutting tools and holders, then determine which
items can be left where they are as useable tools .

Multi-Spindle Set-up Procedures
Tornos 14mm & 16 mm
The Tornos/Becheler multi-Spindle Lathe was engineered for high precision output and production.
The main slide, cross slides, independent advances, and pick-off spindles are vital components that are strategically
placed and driven by a single camshaft located on the top of the machine.
The flat cams for the cross slides and bell cams for the main slide, independent advances, and the pick-off spindles are
easy to access and change.
Major Features
---------
The carrier is indexed by a Manifold system and locked by a Hirth coupling.
Stationary or revolving end working units with different drilling ratio.
Differential tapping/threading attachment. (Cut or Rolled)
Pick-Off spindle for Back Operations.
The machine is capable of overlapping back operations such as;
--- Back turning
--- Back drilling
--- Chamfering

On Cross Slide #6, Always use correct keyway depending on specific machine.
(AS = 14mm Machine
--SAS = 16mm Machine)
Independent Spindle Cams
-------
Remove and install Independent Spindle Cams per layout sheet.
Adjust drop-off timing to be exactly (or 3 degrees before)
the same as the Main Slide Cam.
Set Positive Return Cam for roll clearance.
Note:
--Positive Return Cams are always left installed in machine.
--1st and 2nd position cams use a mechanical 2:1 travel ratio.
Pick-Off Cam
-------
Remove and install Pick-Off Cam per layout sheet.
Adjust 300 deg cam marker with 300 deg machine indicator.
Check that cam roller passes through cam split without interference.
Note:
--When changing pick-off cam having a rise larger than 1.0mm,
release pick-off location and back operation stops.(See Page# 53)

Cut-Off Tool Holder
---
Loosen Hold – Down “T” Bolt and remove cut-off holder.
---
Remove cut-off blade from holder and grind to angles shown below.
---
Insert sharpened cut-off blade into holder AS 30/121 using adjusting square.
---
Tighten clamps and remove adjusting square.
---
Mount holder AS 30/121 onto cut-off slide by engaging ‘T’ Bolt into ‘T’ Slot
and tighten.
---
Make longitudinal adjustment as close as possible to the work collet.
Note:
If workpiece has a thread on the cut-off end then the cut-off tool
should be set at 3/8” minimum from the work collet.
Note:
-Always have a sharpened cut-off tool ready for quick changeover to minimize downtime.
-- Resharpen original after machine is running .

Independent Spindles
Mount All Independent Spindles and Fixed Drilling Attachments as shown on the layout sheet.
Non-Revolving
---
Select spindles per layout sheet.
---
Pre-Assemble correct fork(see page #23). (Outside machine)
---
Install The End of Stroke Stop Rod into the machine.(see page# 42)
---
Install spindle assembly into machine.
---
At the time of cutting tool installation, The End of Stroke Stop Rod
is adjusted as follows;
Adjustment
Set spindle travel by adjusting positioning nut ‘A’ and ‘B’ (see page# 53)
to machine the workpiece .002” (max.) shorter than the print dimension.
Then adjust stop nuts to restrict tool travel to accomplish correct part length.
(This is done with the Independent Cam on it’s highest point.)
End of Stroke Stop Rod
---
The End of Stroke Stop Rod is used to control the workpiece depth
of counterbores, recess location, and some broaching operations.
Note:
This rod is used without the limit nuts when no precision
workpiece dimension is required. example: Spotting & Drilling.
Revolving
---
Select spindles per layout sheet.
---
Install spindle assembly into machine.
---
Install correct fork and threading trip rod if threading is being done.
---
No End Of Stroke Stop Rod is required when using Revolving Spindles.
---
After completing above steps, connect all Independent Spindle lubricating lines.
---
Manually rotate spindles to verify correct rotation direction. If no quill rotation
is present see page # 54 thru #65 for revolving quill gear combinations.

larger than the finished workpiece dimension.
***
If this formed diameter is a finish form, then adjust cross slide to cut workpiece
diameter .002” undersize, then set cross slide pressure stop until exact
workpiece diameter is attained.
(Note: Cross Slide pressure stop should be set with a max. of .002” pressure.)
Note: When rough forming the side of a flange, allow .003” per side for shaving.

If the differential threading drive AS 26/17 is already mounted on the machine, it is possible to use the quills
AS 28/1A (Fig. 55-1) for the drive of the self-opening dies. In this case, it is necessary to disconnect the
disengaging device of the threading drive. No differential threading is possible under these conditions.
Also, it is possible to use the same set-up of threading quills AS 28/1A and self-opening die quill AS 28/1H, in
order to obtain a tapping and threading operation working independently from each other. In this case, the
differential threading will be done in position 3,4 or 5 and the self-opening die will have to be mounted in
position 3,5 or 6.

If the threading clutch drive AS 26/17 is already mounted in position 4, it can be synchronized with the help of gears (Tl-T2)

Quills For High Speed Drilling ( 2X Speed of Work Spindle)
With a direction of rotation opposite to that of the work spindle, requires the use of
intermediate quills. For the combinations mentioned below, except cases (60-1) and (60-2),
the drills turn at the same speed as the work spindles, but in the opposite direction. This is
equivalent to drilling "2 times the speed of the spindles" (relative speed).

* Remove gears T1 + T2 + D1 + D2
This will reverse drilling rotation from the work spindles.
For the drive AS 26/17, take off the tapping gears Tl and T2 and the
thread return gears (Dl and D2).
No tapping operation is possible under these conditions.
Note:
If a synchronized attachment is used when setting up the machine, it will suppress the
quill AS 28/1E (Fig. 59-2).
In this case, add a gear AS 2859 in place of the ring AS 2867 of the synchronized quill
and assemble a quill AS 28/IF on the adjacent position to reverse the direction of
rotation of the central gear AS 20575. The equipment of the other positions remains the
same.
Max. revs/min on the work spindles equalls 4000.

(With Threading Clutch # AS 26/17)
(No Tapping Possibile)
Speed variations are accomplished by changing threading gears T1 & T2
per gear chart on page # 68.

(IG = Idle Gear)
This allows simultaneous drilling in two positions;

5 or 6
No tapping possible.
Note: The above quill combinations are all driven from pos. #1 (AS 26/2) through an
idle gear to pos. #4 (as 26/17), then thru an additional Idle Gear to the next
transfer position as indicated above, with the drilling power ending at the
specific drilling position.

(Variable Speed) Quills for Low Speed Drills
For drilling or boring with identical direction of 'rotation to that of the spindles. (Use the drive for
self-opening dies AS 26/2 or the drive of the tapping attachment AS 26/17).
Concerning the obtainable differences of speed and the gears TI-T2 to be placed on the drive
of the tapping attachment, see table page# 68.

Causes Of Broken Shear Pin
---
(Profile Material) Mis-alignment between pick-off collet and work collet.
---
Excessive pressure on pick-off location stop.
---
Excessive pressure on pick-off back operation positive stop.
---
Excessive pick-off collet tension.
---
Chip interferance, causing excessive pick-off collet tension.
---
Broken twist drill through cut-off.
---
Check for broken springs in the ‘Pick-Off Spindle Stopping Quill’.
(See Tornos service manual pg# 13/18 ~ fig.# 1307 for more detail.)
---
Workpiece not ejecting out of pick-off collet.
---
Check for possible Dull Back Operation Tool.
Shear Pin Removal
---
Remove Retainer Screw (A).
---
Remove Shear Pin Retainer Plate (B) by sliding plate until disengaged from
shear pin head.
---
Push broken shear pin toward rear of lever.
Shear Pin Replacement
-----
Insert new shear pin from rear side of lever.
(Note: Avoid moving eccentric bushing.)
Re-assemble retainer plate (B) and retainer screw (A).
