detailed product description

The basic idea of the universal cutting machine is the machine-supported manufacture of molded parts by means of a cutting procedure proven for decades in fine sheet machining: the electric sheet shears, in a strongly revised execution.

With 3 high-performance and highly precise step motors, the shears go through the sheet “as if by hand”, but with high repeat accuracy.

All mechanical components are overdimensioned in order to guarantee many years of smooth system operation.

The molded parts are fundamentally cut out ready-to-use and with the hole-drilling unit, a major portion of the work preparation is saved. The time-consuming process of marking bending lines, especially for transition pieces and flattenings, is no longer necessary.

Our new special accessory, marking unit, enables you to mark positive/negative beads, helpful bending lines or other special customer requirements and position numbers.

 

EFM_Bohrer_detailA Windows PC ensures that calculations are fast and precise, even for the most complicated processes. The intuitive operating program was developed on our premises and is tuned to the special needs of insulators.

The standard scope of delivery already includes 50 programs which cover most of the work involved in the daily routine of an insulating plumber. We are willing to realize new customer ideas as program extensions.

We always strive to simplify the input of even the most complicated specifications. For example, a bent connecting piece is computed in all directions at the same time: turned, inclined, conical + 3x flattened, optionally with/without triangular transition. The same applies for seam positions, seam angles, circumferential parts, etc. As a control, there is a 3D preview included in the standard scope of delivery, which shows you exactly the precision  of the dimensions and the position of welded seams and flattenings.

 

ISO_Award

Special designed software including different helpful functions like additions for bead, overlap and others allows you to create automatic tables which can take into account different diameters of the pieces. Depending on requirements of the customer it is also possible to make several tables at once which are made exactly for each project or each customer or each company.

The machine was nominated several times for the „Best innovations of the year” award at “ISO” – the worlds largest trade-fair in the insulation business. In 2004 and 2010 it was awarded  with the first price for the “Computer Based Measurement and Production System – Capi”.

Different types of models can be entered and sent via Intranet/Internet. So one employee can be just on the building site with a laptop and transfer all  details directly to the machine via GPRS / UMTS.

The exact cut is guaranteed by high-resolution, high-performance step motors. These are gently and variably accelerated and decelerated in online mode, depending on the traversed curve, in order to guarantee the smooth, uniform behaviour of the cutting tool.

The machine is equipped with pneumatic hole-drilling unit for drilling fastening holes or bending points. Special pneumatic locks hold a steel sheet on the working table to ensure the precision of the holes.

An integrated electronically controlled lubrication device drops some oil onto the drill that helps to prolong its term and improve also the quality of the hole.

To increase the efficiency of your workshop the machine can be integrated in a computer controlled manufacturing process: with the help of Internet /Intranet it is possible to syncronise the data between a Laptop / tablet PC, the office-computer and other computerised  or mobile devices.

There is an opportunity to send wirelessly current information about models from the building site to the EFM-L or cut-to-length machines like KTE or ISO-CUT and after that to cut all pieces from the steel sheets with already punched holes. For the post calculation there are several helpful tables at your disposal with information about general consumption of the steel (net / gross), general time for cutting etc.

If you wish you can equip EFM-L with our new unique marking system offering many possibilities:

  • Marking of rest-sheets and its storage in a database for later use
  • Numbering of pieces due to measurement for a fast parts identification
  • Marking of current data for following working steps like position of beads, direction of rounding
  • Marking of bending lines or points (e.g. adapter piece:round-angular etc.)

 

 

EFM_PEN_detail_2_wz
isometry-start_05

The software is special created for all needs of insulation plumber. The 3D graphics of each piece helps you to make much easier the input and to avoid unexpected errors!

For example, the program “Pipe Isometry” allows pipelines to be entered with graphical support.

By touching the coloured arrows on the touch-screen display, you can create the whole pipeline system and then change by some parameters e.g. axis lengths . Every changed parameter is displayed directly; this way (wysiwyg – what you see is what you get), you can see the finished product before installation and can avoid input errors!

Even complicated connections can be input quickly and clearly, because you have always a possibility to have a look at the position of seams, bend angles etc.

Thanks to unlimited working possibilities you can create different pipelines, your competitor would dream of such a machine EFM-L. What about a double pipe bend with a conical segment in the middle, flattening and connecting piece included!

isometrie-beispiel_3d_04  skizze01_06

EFM_Etikett_06
This way, up to 40 isometries can be put together at once, which the program optimizes to minimize leftover sheet metal.

If you wish you can print coloured drawings of the pipeline for your documentation purposes or also a label with technical data of each segment and logo with your company.

 

It is also possible to produce insulation pipes using the cut-to-length line FLEX-CUT. The program automatically calculates and looks for the optimal way to cut initial and final pieces. The information about holes calculation is sent to the machine via wireless connection and he holes will be punched on the steel sheets.

The EFM-L cuts then ready segments from the pre-punched steel sheets!

data-series-caps

The program “Series Caps”, for rationally manufacturing diverse caps, can be used to enter and cut single or entire series of different caps, quickly and easily.

The program controls all common shapes (flange, fitting and suitcase form) and divisions (even asymmetrical).

Working with basic data and an ingenious, automatic add-on program makes input easier. This basic data is pre-set into your system during training and can be easily changed. This means, that a standard cap can be input within a few seconds, as only the shape, division and diameter have to be entered into the table.

All details regarding a single cap can be easily adapted, e.g. caps with indented lock seam, roof-top shape, flattenings and many more. And they can be looked at on the 3D preview.

Calculating and cutting covers and headplates of caps on different steel sheets allow you to work with any types of steel/sheet thickness.

Surely you have some metal sheets left over from the previous cuts! For this case the EFM-L offers you a unique chance to use them again for cutting of caps or their bodies.

The program provides you an opportunity to work with the leftover sheet table. The machine looks for the best way to cut the sheet, before you place a fresh sheet in the system!In a such way you can reduce the left over of the steel!

 

The program Series Caps provides a further important details, which make the whole manufacturing much easier:

  • By touching the button you can switch to the tooth fold (cap, standing, outside)
  • Free position of holes for fastening of insulation
  • Manufacturing of covers and headplates from different types of steel
  • Platal function (for coated sheets)
  • cut-preview-capsHoles on quarter parts for easy mounting
  • Cutting of cap bands with prepared holes for toggle clips and adhesion
  • Print of labels with company”s logo
  • Marking the corner radii on the cover of box
  • Cutting of end discs (for pipes)
  • Possibility to integrate in existing business software for automatic data transfer
  • Printout of production table for manufacturing

 

 

Besides the two introduced programs, the software package includes many other programs for rationally producing molded articles, such as bends, bundle conductors, contactors, funnels, tank heads, tank feet, flattenings, etc. With the 3D preview you always have an overview.

Example:
Bend segment, flattened 2x.

1.1st flattening on the back, trapezoidal
2. 2nd flattening on the side with transitions as triangle.
The flattenings intersect each other!

 

Example:
Contactors (grey) on bend segment.

The contactor can be turned in every desired position by means of 3 angles (even laterally and in the flute).

Example:
Contactors (green) on zeppelin head (tank foot).

The contactor can also be designed in conical form and can touch the tank head at any place (transition between corner radius and tank radius is taken into consideration).


Example:
Bend segment in multiple piece number cut in series.

The powerful program package „Ventilation“ offers you a great opportunity to create and cut different insulation parts and pipelines for ventilation systems. Hereby, simple handling, a clear overview with 3D and versatility are perfectly reunified:

  • Automatic additions for external/internal areas
  • Flattened ventilation pipes
  • Free position of fastening holes
  • Free choice of segments
  • Bending points marked
  • Calculating of bending angles
