The chuck is supplied with 4 Quick•Point®clamping studs. This enables clamping in the
zero-point clamping system of LANG Technik GmbH, which is mounted on the machine
table of the machine tool. The following zero-point clamping systems of LANG Technik
GmbH are suitable for this:
Quick•Point®zero-pointplatewith96 mmgriddimension(manualoperation)
RoboTrex 96 automation base tower (automated operation)
1.7
The chuck can be used with automatic grippers in the machine tool (machining centre).
Manual use is also possible.
Inbothcases,afurther,suitablemountingsystemisnecessaryforxingthechucksafely
on the machine table. The Quick•Point®96 zero-point clamping systems of LANG Technik
GmbH are suitable.
Automated application (batch production):
For example, for batch production. The workpiece is clamped in the chuck manually
outside of the machine and is kept in a magazine. The chuck, including the clamped-
in workpiece, is then removed from the magazine by an automatic gripper. The
gripper positions the chuck in the zero-point clamping system in the metal cutting
machine. An integrated interface in the chuck (see Item 5, Structure section) ensures
secure gripping. After the machining the chuck together with the workpiece is placed
back in the magazine automatically.
Manual use (individual production):
The workpiece, as for batch production, is clamped in the chuck manually outside of
the machine.
Unlike the automated application, in the manual application the metal cutting machi-
ne is loaded and unloaded by the operating personnel.
Clamp workpieces:
The clamping mechanism for clamping/unclamping the workpieces is achieved by
turning the worm shaft (see Fig. 3, Item 6).

3.1
Mounting add-on jaws
The add-on jaws are latched into the base jaws from above using pressure only; there is no
need for tools thanks to the click system.
Place the add-on jaws on the middle of the base jaws.
Latch into position by applying pressure from above. Movement direction from the
inside to the outside.
The add-on jaws can be offset one notch inwards or outwards to utilise the full clamping
range.
Three or six jaws can be used, depending on the application case.
Dismantling add-on jaws
Pull off in the direction of the middle of the jaw chuck, without any need for tools.
3.2
WARNING! Risk of injury! Moving machine elements can cause severe injuries
during setting-up.
Secure the machine in which the chuck is used to prevent it from starting up.

If the workholding is defective, parts of the tool or workpiece can be ejected / fly
out into the surroundings and cause severe injuries.
Damage to the product must be corrected completely and properly by trained skilled
personnel (with metalworking training) before starting up the machine.
The product may only be installed by trained and instructed skilled personnel (e.g. CNC
millers).
If the jaw chuck has already been used, ensure that it is clean (no dirt, swarf).
NOTE Requirement for fixing on a machine table
You require a suitable clamping system to clamp the jaw chuck on a machine table.
Regardless of whether the clamping is carried out manually or automatically.
The chuck is supplied with 4 mounted Quick•Point®clamping studs. The bolts enable zero-point
clamping on the machine table of a machine tool/machining centre, only in conjunction with
otherxingsystems(optionalaccessories)ofLangTechnikGmbH.Forexample:
A Quick•Point®zero-point plate with 96 mm grid dimension (for manual operation).
A RoboTrex 96 automation base tower (for automatic operation).
ÎFamiliarise yourself with its handling.
1. Clean the mounting surfaces of the chuck and of the machine tool. They must be
completely clean with neither dirt nor swarf.
2. Place the chuck in the zero-point clamping system or in an alternative mounting device
in the machine tool.
3. Actuate the clamping mechanism of the zero-point clamping system or an alternative
mounting device, as specified by the manufacturer.
4. The chuck is now ready for the workholder. See Operation section.
The chuck can also be integrated in an automatic loading and unloading system. For exam-
ple, in the RoboTrex 96 automation system of LANG Technik:
In this system, several chucks can be kept in an automation trolley.
The chucks can be equipped with workpieces directly in the automation trolley or
elsewhere.
A robot arm removes the equipped chuck with its gripper and loads the machine
tool. After the machining has been completed the robot arm places the chuck back
on the automation trolley.

out into the surroundings and cause severe injuries.
Before using the jaw chuck and before switching on the machine, check that the machine tool
/ machining centre is in proper working order.
If the jaw chuck has already been used, ensure that it is not damaged and is clean (no dirt,
swarf).
Damage to the jaw chuck must be corrected completely and properly by trained skilled
personnel (with metalworking training) before starting up the machine.
Clamping
A workpiece can be clamped after all
necessary precautions have been taken,
as described in the “Install” section.
1. Check that the workpiece and all
mounting surfaces are free from
dirt and swarf.
2. Place the workpiece in the jaw
chuck.
3. Clamp the workpiece finger-tight by turning the worm shaft (see Figure) clockwise
using a hexagon socket spanner (A/F 8).
4.2
To be able to realize inter diameter clamping, the base jaws must first be changed. For this
purpose, you need item no. 59616-30 (Base jaws for inner diameter clamping). In this con-
text, please read the section „mounting of base jaws“ hereafter.
11
Chapter 4

Unscrew the worm shaft (Fig. 4.1) counterclockwise until all the base jaws no longer move.
They can then be easily removed by hand.
The initial condition for this is a completely assembled jaw chuck without base jaws.
The assembly of the base jaws starts with number 1(see illustration).
4. Position the jaw chuck so that you have the opening of the worm shaft directly in front
of you.
5. Base jaw number 1is inserted into the nearest guide shaft and threaded into the
face spiral. The numbering of the base jaw points outwards.
Turning the worm shaft clockwise causes the face spiral to turn counterclock-
wise.
6. Insert the other base jaws in the opposite direction (counterclockwise). See also numbe-
ring from 1 to 6 on the base jaws and the base body.
During the „threading process“, feel whether the face spiral has also gripped
the base jaw by trying to push the base jaw slightly back and forth.
4.3
Carry out a regular visual check for dirt. If necessary, interrupt operation of the ma-
chine and clean the chuck or the machine (also refer to the “Maintenance” section).
Also refer to the operating instructions of the machine tool.

national regulations, particularly grease and solvents.
With one exception, the mounting is carried out in the reverse order to the dismantling.
The exception is the insertion of the base jaws. The procedure is described in the “Inserting
the base jaws” section.
5.7
The initial condition is that all parts of the jaw chuck are mounted, except for the base jaws.
We begin by mounting the base jaw with number 1.
1. Position the jaw chuck so that the opening of the worm shaft 4is directly in front of
you.
2. In the now nearest guide shaft 1, insert the base jaw number 1 and “thread” into the
scroll 5. The numbering of the base jaw is facing outwards.
Note:
Turning the worm shaft 4clockwise causes the scroll 5to move counter-
clockwise.
3. Insert the other base jaws counterclockwise. See also numbering from 1 to 6 on the
base jaws and the base.
Note: During the “threading in process”, feel whether the scroll has also covered the
base jaws, by trying to move the base jaws slightly to and fro.
