Übersetzung für "Worn tool" in Deutsch

In particular, a worn polishing tool may be exchanged against a fresh polishing tool.

They maintain and repair damaged or worn tool components.

However, it could also be necessary, for example, to replace a worn-out tool with a new one.

A worn out grinding tool can be interchanged without the associated grinding wheel protector having to be changed.

In order to be able to change the tools automatically in numerically controlled milling and drilling machines, the tool spindle in the spindle head or in the vertical milling head must be positioned and fixed exactly in a certain angular position so that the changer can grasp the tool taper of the worn tool securely and can subsequently insert the new tool with its steep-angle taper into the clamping jaws with accuracy.

Also the simple substitution of the worn-out die through a new one is significantly more cost-effective than the refinishing of an entire tool, or even the replacement of a worn out tool by a new one.

This configuration is conceivable for already slightly worn manufacturing tools for manufacturing such clamping jaws and thus ensures the functionality of such clamping jaws even in the situation where they are manufactured with an already worn manufacturing tool.

When the desired tool 20 is in the transfer position, which is pivoted through 90°, the changer arm 74 is pivoted by means of the changer drive 73 in such a way that the first tool clamp 76 removes the worn-out tool 20 from the work spindle 32, and the second tool clamp 76 removes the new tool 20 from the tool magazine 66 .

Afterwards, the changer arm 74 is lifted in the usual manner in the direction of the changer axis 75, is pivoted through 180° about said axis, and lowered down again, allowing the worn-out tool 20 to be received in the tool receptacle 69 and the new tool 20 to be received in the work spindle 32 .

A worn cutting tool can also be rotated out of the machining position and an unused cutting tool can be rotated into the machining position.

In particular in the field of automated mass production, an intervention can be made in a timely manner using the invention, before flawed grinding tools can be produced by a worn dressing tool and unsuitable gear wheels can be produced using these grinding tools.

In this case, for example, the limit force may be defined when monitoring the machining process during ongoing operation (whether continuously or randomly), as one which occurs in conjunction with a maximally permissible worn tool.

Here, too, as part of a monitoring of the machining process (again, whether continuous or random), the limit torque may be defined as one which occurs in conjunction with a maximally permissible worn tool.

For this purpose low-frequency vibrations are recorded by the vibration sensor in order to detect imbalances and/or tool vibrations and thus, for example, to detect a poorly balanced, incorrectly tensioned or worn tool.

A worn tool which is used for the first time in a particular machine tool is considered there to be a new tool since there is no information available about duration of utilization and/or type of utilization of the tool.

This enables the second cutting edge to be exposed in a particularly rapid and simple manner, so that the worn drilling tool can rapidly be used again.

For a user, particularly in the case of drilling tools of large dimensions, it is very advantageous and sparing of resources to expose a second cutting edge, realized as a replacement cutting edge, instead of replacing the worn drilling tool with a new drilling tool.

The tool spindles can then be replaced with their bearings and possibly seals by simple exchange of the bearing bushes in the structural unit, for example when they are worn or when tool spindles for other machining tools are to be used.

This ensures that, for example, after replacing a broken or worn tool, the dimensional accuracy of the centering bores can be checked without great time loss, to then quickly proceed with the production.

Worn shank tools are restored with modern technology.

On the one hand, this allows for a simple replacement of worn roller tools.

Worn tools 32 are also placed on the transport device 57 and removed.

Worn tools are resharpened to the same standards as our new tools.

This allows employees to detect any worn tools immediately and replace them.

The manufacturer does not accept any responsibility for damage caused by worn floor tools.

Poor surfaces, for example, caused by worn out tools, can be recognized during the process.

In order for this to happen, we need to shake off the fatal spirit of defeatism besieging us at present and regain the spirit of determination of Lisbon, even if the present, disastrous circumstances for the Union can be summed up in the words of Kipling: 'If you can bear to see your life's work broken and stoop again, build it again with worn-out tools'.

Accordingly, since the invention provides multiple tools, preferably two, on one tool body, and individual or all tool bodies are positioned in a swivelling manner which enables the tools to be utilized in an alternating manner, it is possible to replace worn tools or even to substitute tools with other profiles without great expenditure of time.

The worn tools must then be replaced in the tool magazine by fresh ones which, in the case of conventional disk or chain magazines, causes relatively frequent interference in the machining operation because loading of the respective magazine with tools must normally be performed manually while the machine is shut down.

It is one of the significant advantages of the concept according to the invention that the magazine segments or sections may be prepared in the shop and made available directly at the machine tool so that they can automatically replace, as required in accordance with the respective control program, magazine segments loaded with "worn" tools.

By subsequent rotation of turntable 15 into alignment with the pair of tracks 27, 28 or 29, 30 and subsequent extension of piston rod 25 magazine segment 6, which contains the worn tools, is moved to a store position.
