常问问题

Before, 4 Nm were to be applied to all manual Macro chucks. Today only 3R-600.20 remains with 4 Nm and the other manual chucks are to be operated by 6 Nm. Recommended torque wrenches are either 3R-614-04 (i.e. 4 Nm) or 3R-614-06 (i.e. 6 Nm).

This has been solved by releasing 3Refix mandrels by Torx 20 interface. These are available by EDM, WEDM or PM versions, side by side with the original version. EDM: 3R-901-10-TX, WEDM: 3R-901-10RS-TX and PM: 3R-901-10PM-TX.

This problem is possible if thin workpieces are to be machined and the cover of upper guidance is too large. An alternative, is to apply adapter 3R-SP31549 (see D-30241) onto either 3R-262HP or 3R-272HP in order to avoid collision with upper head.

There is a great variety of vice for horizontal and vertical holding and for rectangular and round workpieces.

The levelling heads utilize the same internal components with springplate and/or springs. Both have width 70 mm that rest onto z-references or undeneath contact surface. You may say they are equal by stability.

Chucks are normally delivered as "rough balanced". It means that they have been balanced on drawing board by G6.3 to a certain level. In production, tolerances may be in favor for better performance. But all together, the balancing has to be made after assembly in machine. For more specific values, get in touch with System 3R and ask for more detailed related to "imbalanced chucks".

Up to 100 °C (212 °F) for regular Macro tooling and above that, o-rings, plastic parts and grease will be lost. In worst case scenario, we are able to provide Macro tooling by Inconell material that will withstand temperatures up to 600 °C (1112 °F).

In short: less than 15% clamping force, unit should be due service. Over the years, we have designed, produced and delivered a huge range of chucks by various clamping force. To verify state of chuck, have nominal value verified by System 3R's Customer Services.

There are documents available that makes a wide coverage. Please contact System 3R's Customer Services.

Two simple guidelines "Splitting Microns" and "Splitting Microns - PM" have been published giving attention to this subject. Please get in contact with System 3R's Customer Services for further information

There is a flyer prepared addressing this issue and helping old Mecatool customers. Please get in contact with System 3R Customer Services for further information.

There are separate TPS-General Info prepared, for each tooling range. The area for Macro chucks, had to be split up by three separate sections: Macro Flat chucks (short drawbars), Macro Tall (long drawbars) and Macro PM. Please contact System 3R Customer services for further information.

ID-carriers for automation was introduced long time after Macro pallets were introduced. There are still customers that want to add cavity to attach ID-carrier in a proper way. For further information please contact System 3R customer services.

We have by Macro and MacroMagnum, instructions as how to modify and implement a solution. See document "Disable index function by Macro" for Macro and "TPS - 90940.12-10" for MacroMagnum. For Matrix products, it has been incorporated by the design and operator only need to replace the rough alignment pins by either 3R-SP29196, 3R-SP29533E or 3R-SP29559E, depending on size of chuck.

It is rather common that customer asks for this in order to maximize the machine capacity on the table side. Please prepare with a drawing for suitable size and contact System 3R Customer services.

There are guidepins 3R-SP27713E to be ordered that works just fine for this purpose and covers the range Matrix142 up to Matrix260. These can also be combined with index blocking pins 3R-SP29553E or 3R-SP29559E.

Add a special distance kit, will enable the use of long drawbars. Some customers ask for this in order to reduce number of various versions of drawbars in their workshop.

There are individual documents refered to as MICnet drawings. Visit www.system3r.com. And you will find several solutions for different machine brands and models/versions

There are no particular guidelines to follow. There are however examples based on what most customers do.

There are several options depending on which shank you have in mind.

There are several adapters available though few displayed in catalogues. For automatic chuck adapters. Please get in contact with System 3R customer services.

Most of these holders only require to replace the movable jaw. Please ask System 3R Customer services for further information.

Customer experience inaccuracy either by repetition or during machining operation. Most often, it is purely related to lack of clean surfaces or a belief that the mandrels alone will hold the part in place.

Chuck, levelling head and vice, present different values for maximum payload. How this should be interpreted is displayed in a document. Ask System 3R Customer services.

Either lack of service to internal wear parts (o-rings) which will make the chuck not work properly, or relieve pressure has been blocked or clogged muffler on the return outlet. Contact System 3r Customer Services.

For C400iB and C600iB, there is a converter cable to apply together with 3R-60.360F4 unit. This to adapt the cabling to Fanuc with three separate plugs to the machine interface. Converter cable 51461-00.

By creating a regulated slight overpressure, the surface of chuck will remain dry.

While introducing MacroJunior and MacroCombi, System 3R supplied individual tailor made solutions to various machines. Later on, OEMs adopted and supplied forks on their own. There are documents to verify suitable forks. Get in contact with System 3R Customer Services.

There are two alternatives made available. #1 for chucks requiring short drawbar 3R-605.10 (example 3R-602.10-1) and #2 alternative for 3R-605.1RS (example 3R-SP7359-RS).

There are two versions of 3Ruler interface and in addtion the EconoRuler that requires three different lenghts of screws.

There are procedures/steps to be taken in order to level a SuperVice as accurate as possible. There is however a difference between those for rectangular/square versus round workpieces.
