Precision engineering
In the area of precision engineering, during our existence on the market, we helped many customers to meet their requirements. Whether it was the production of a small part exactly made-to-measure, but also the reverse engineering process of the product.
Based on the supplied 3D model will our designers prepare the overall construction of the mold, punch, tool, or the construction of electrodes for electro erosive processing. This activity is called CAD (Computer-aided design).
We perform CAD construction using the SolidWorks, where we process complete drawing documentation for production. We`ll create necessary models for subsequent programming in CAM software. CAM (Computer-aided manufacturing) is for us a selection of a suitable strategy for fast and economical production using CAM software HSM Works and SolidCAM. We upload the prepared programs to the equipment within the CNC machining division and start the production of the final product (mold, cutting tool, electrode, etc.).
Supported formats are:
– PARASOLID (.x_t)
– IGES (.igs)
– STEP (.step, .stp)
After the complete documentation processing at the construction department, our specialists will take over the data and will take care of precise production on the CNC division.
We provide these services on the CNC division for our customers:
– CNC milling
– CNC excavating
– CNC wire cutting
– CNC production of electrodes
CNC milling:
We have three three-axis vertical machining centers available. Thanks to the accelerating head at 45,000 Rpm, we`re able to mill with millers from 0.6 mm in diameter. We`re milling materials from soft one (aluminum, copper, brass, bronze and AMPCO alloys) to steel with a hardness of 62 HRC. The maximum dimensions of workpieces that we can produce are: x: 950 mm, y: 550 mm, z: 500 mm with a maximum load of 1,350 kg.
CNC excavating:
Thanks to our own construction department and production of electrodes, we`re able to excavate almost every desired shape. As well as holes from the diameter of 3H7, but also repairs by sinking after welding and recess of broken die taps. The most commonly used excavation materials are steel (hardened and soft) and also AMPCO alloys. The maximum dimensions of the workpieces that we can produce are: 900 x 550 x 350 mm with a maximum load 700 kg and maximum wight of electrode 50 kg.
CNC wire cutting:
Wire cutting is very effective solutions. It`s the cutting with zero force with no contact between the cutting tool and the workpiece. EDM wire cutting leaves perfect surfaces and allows you to cut even very small parts such as medical needles. The most common wire-cut materials are steel (soft and hardened), copper, production of electrodes, AMPCO alloys and other. The maximal dimensions of the workpieces that we are able to process are: 1 050 x 800 x 300 mm with a maximum load 1500 kg.
CNC production of electrodes:
The development of electro erosive processing is more and more sophisticated, so graphite as a material has replaced the copper used yet. The advantages of graphite over copper are:
– lower extensibility
– lower density
– the possibility of the production of thin-walled electrodes
Graphite shows less degradation and thus allows accurate sparking of sharper edges. The maximum dimensions what we`re able to produce are 1 050 x 800 x 295 mm with maximal weight of workpiece to 1 500 kg.
We make 3D measurements on a CMM (Coordinate-measuring machine) Leader machine with a measuring range: x: 800 mm, y: 1 000 mm, z: 700 mm and with maximal weight 1 000 kg. Based on the measured points, the software generates ideal geometric shapes, respective allows measurements based on CAD models. Measured data can be then exported to .xls, .csv, .igs, or output to text, or to graphic protocols, PDF, or QDAS.
Laser scanning is helpful when you need to create documentation for the repair, replacement, modification of hardly damaged parts, or for models of parts with lack of documentation. This is also possible for parts on which the shape modification has been performed and it’s not possible to obtain new dimensions. After scanning the parts using a laser scanner the points cloud is created. This points of cloud we clean in special software from noise and unnecessary elements, whereby we will prepare the scanned data for the creation of a polygon network. Next, the resulting polygon network is further processed into a CAD model.
Basic parameters:
– maximum dimensions 700 x 800 x 600 mm
– maximum weight 1 000 kg
– scanner resolution +/- 0,02 mm
– minimum distance of scanned points (raster) 0,1 x 0,1 mm
What we can scan?
– more-less all parts except objects that change its shape and living objects
Optical scanning is a helpful solution not only for reverse engineering but also quality control. Using the optical scanner, you can cleverly scan the parts and convert them into a 3D model using the supplied software. At quality control, you can analyze all surface and dimensional problems. At reverse engineering, you get a 3D model, based on which you can reconstruct the original part. Presently, we can help our customers not only with static solutions using the HEAVY DUTY BASIC, OPTIMA, QUADRO scanners, but also robotic 3DRO solution. For these solutions, we are the exclusive implementer of EVATRONIX 3D optical scanners.
