2.2 I use already a CAD system. Is the use of your CAD/CAM solutions isy CAM 2.5 / isy CAM 3.2 necessary for the operation of the CNC unit?
2.3 Which hardware requirements are necessary for using software isy CAM?
2.4 Is it possible to import and work on (mill) NC-data in the G-code - format (DIN ISO 66025), which are from alternative CAM systems?
3- Main Spindle Drives (milling spindles)
3.1 What is the difference between a pneumatic direct changer and an automatic tool changer with steep taper clamping?
1- CNC control and drive technology
1.1 What is the difference between stepper and servo motor technology?
The servo-drive is a controlled (closed) system.
The servo motor has a shaft encoder for distance measurement, and/or. finding of the current position. Therefore a constant variance comparison proceed. Thus the servo drive drives accurately in accordance to the given path profile. Beyond that the servo motor has a high torque via the entire speed range.
The stepping motor drive is a controlled (open) system. The positioning proceeds via the default of the number of control pulses (steps). The torque decreases via the speed range, during exceeding the risk of " step loss " exists.
Advantage of the servo motor opposite to the stepper motor:
- finding the current position.
- constant variance comparison.
- homogeneous path operation/path behavior (Look ahead).
- higher dynamics => substantially higher feed motions and speeds
1.2 Wherein differs DC from AC servo motor technology?
DC servo motors are brush-afflicted (carbon brushes) motors. AC servo motors are brushless and thus maintenance-free motors. Furthermore the AC servo motors have very calm running properties, substantially higher dynamics and a very good control mode.
1.3
A linear motor is an electric motor in a " spread condition ".
Normally feeding forces are produced by a turning electric motor (DC /AC servo motor) and converted in a translational motion. The movement is thus caused " indirectly ". Linear motors make possible to represent directly a translational movement, therefore they are called " direct drives ".
Advantages of the linear motor:
- very high dynamics and high acceleration
- no mechanical friction
- no reversal play
- no axis or positioning problem
- no mechanical transfer elements
1.4 What is the meaning of HSC milling (HSC milling technology)?
HSC milling stands for High speed Cutting.
Conditions for HSC milling are:
- high-dynamic machines with very quick control technique (control cycle time < 1ms), in order to be able to hold high feeding speeds and the path constancy also with complex geometry forms
- stable mechanical structure of CNC unit with good absorption characteristics
- high frequency spindles, which in particular make the necessary numbers of revolutions available with the very frequently used small tools
- highest true running accuracy (approx. 3 to 4 µm)
- CAD/CAM systems with HSC milling strategy
The CNC machine in the product group " HSC PREMIUM " fulfill all these criteria.

2- CAD/CAM/CNC software
2.1
What is the difference between the control programs WIN remote and MM2000? Which will be used at which CNC unit?
Both programs are control programs (interpreter programs) for operating CNC units and processing the NC programs.
The program WIN Remote finds its application in all units of the product group " economy ", as well as in the rack units of series of GFV with DC servo motor technique. WIN Remote communicates with different controls: IMC4, Multi- F (Logosol), CAN BUS.
The program MM2000 is the operating interface of the HMC2000 control and therefore ready for use on all units (GFY/GPY/SFY/SPY,PREMIUM series) with AC servo or linear motor technology
2.2
I use already a CAD system. Is the use of your CAD/CAM solutions isy CAM 2.5 / isy CAM 3.2 necessary for the operation of the CNC unit?
Program isy CAM 2.5 light is the base software of all CNC units. This program which can be used easily permits on one side to construct 2D contours as well as importing and proceeding external data e.g. DXF, AI or EPS. On the other side the NC paths are generated by the integrated CAM module with all imaginable milling strategies.
Program isy CAM 3.2 can be acquired optionally and enables all functions of a professional employment for construction and machining 3D parts.
If you already work with a CAM system the use is not compellingly necessary. But we will be glad to convince you about the indescribable advantages of this unique CAD/CAM software with a probably singular price / achievement relationship at the market.
2.3 Which hardware requirements are necessary for using software isy CAM?
For the use of the program isy CAM are no prescribed hardware conditions. Each commercial computer is suitable for the various application possibilities.
2.4
Is it possible to import and work on (mill) NC-data in the G-code - format (DIN ISO 66025), which are from alternative CAM systems?
Using control and operating interface MM2000 import of G-Code files is possible according to standard.
Using WIN Remote we offer a special extension module. If you have any further question please do not hesitate to contact our selling team: +49(0)6672-898 228

3- Main Spindle Drives (milling spindles)
3.1 What is the difference between a pneumatic direct changer and an automatic tool changer with steep taper clamping?
Using a pneumatic direct changing system the milling tools are put directly into the tool station. The position of the tool is limited by special fixing rings, which are covered over the milling tools.
