1.3 Intended Use

Use the tool-grippers only for the intended use. Insufficiently clamped tools or work-pieces, failure

to comply „safety and accident prevention regulations“, and the use of work-pieces and our

products on machines that are not intended for this propose, can result in personal injury and

damages to the clamping devices. In this case, we shall assume no liability. Do not apply force

during assembly, disassembly and operation; this could damage the clamping device or the

machine.

1.4 Initial start-up

A function check is implicitly before initial operation of the tool-gripper. To ensure a safe and

precise operation of the tool-gripper during machining, a sufficient clamping force must be

provided. Check the clamping force.

See: Checklist for Installation p.6

The tool-gripper, especially the function surfaces must be clean and lubricated sufficiently. It is

strongly recommended to grease with suitable assembling grease.

Never exceed the axial and radial forces specified on the tool-gripper.

Check the clamping force regularly!

1.5 Checklist for Installation

1.) Tool –“Eject” max. 1.0 mm. The tool is only drawn in securely by the tool gripper in this

range. Ensure that the clamping reserve is min. 2 mm and max. 3 mm.

2.) Check the clamping force. The max. pull-in force, Fz max. , must not be exceeded.

3.) Tool clamping must not be one-sided. Guide the disc spring stack accurately.

4.) Spindle receiver must meet DIN 69871 /72 standard and Ortlieb installation dimensions.

Functional surfaces hardened min. 1mm deep to HRc 60

+2.

5.) Observe the control operation.

Insert the tool until it reaches the limit stop at the draw-bolt plane surface, then clamp it.

Clamping must not de done too soon, as otherwise the clamping segments are not

disengaged can properly and can be damaged.

6.) Tool change: Grip the tool – eject – unclamp - blow-out. Make sure that the tool and

spindle are clean. If chips are drawn in, clamping segments will sustain damage.

(One-sided overloading of the clamping segments).

7.) If one clamping segment breaks, the tool will nevertheless be clamped safely. However

the tool-gripper must be exchanged immediately as a complete unit.

8.) The tool-gripper is a part which is subject to wear. Under favourable operation conditions,

the complete tool-gripper must be exchanged every 1x10

load alternations. We do not

assume liability and guarantee on consequential damages in case only parts are

exchanged.

9.) Refer to the Mounting instructions p.11 for information about how to change the tool-

gripper! Before installing the tool-gripper, check the spindle for damage. Grease the

functional surfaces.

10.) For optimal drawing-in force, RPM

max.

and n

max.

, please refer to data on the installation

drawing.

11.) Tools must meet DIN 69871 /72 standards.

12.) Without an HSK tool insert, there is no operation of the spindle allowed. (Out-of-balance!)

13.) After every crash, the tool-gripper must always be exchanged completely.

14.) The clamping force transmitted to the tool shank by the tool-gripper may not be below the

incident machining forces and torques. It is also important that the functional surfaces and

the clamping system are greased regularly (Metaflux lubricant metal paste)

Based on experience, re-greasing should be done after every 200.000 load alternations

at the least in order to keep the clamping force as uniform as possible. Regular

measurement of the clamping force, either quarterly or semi-annual, will ensure the

required safety for the work process. (See p.12)

15.) Check the tightening of the draw-bolt and the drawbar regularly to ensure a proper

function of the tool-gripper.

A loose draw-bolt causes a loss of clamping force and ejects the tool far over the allowed

max. 1,0mm.

2 Product description

The Ortlieb tool-grippers for tool shanks with 7/24-taper are an approved serial product for

automatic tool changing. They are clamping tools with ISO taper (7/24) and pull studs acc.

DIN 69871/72. The six-piece clamping segment has an optimal load balancing. Therfore a higher

permitted clamping force is possible. And this at faster cyles.

Function:

Milling spindles on machine tools are usually fitted with conventional spring loaded tool clamping

systems. The tool-gripper operates on pulling force.

The six-piece clamping segment is pulled by the draw-bolt into the machine spindle. The clamping

segment catches the pull stud of the tool and pulls it into the spindle whereas the clamping

segments are backed radial by the spindle-bore.

To change the tool, the disk springs were compressed, usually by a hydraulic cylinder. The draw-

bolt is pushed by the drawbar to the front, releases the clamping segments and pushes the tool by

force out of the spindle taper. The ring spring provides the opening of the clamping segments

which release the tool for changing.
