Turning

Turning is one of the main operations metal can be machined. The process is performed by cutting the metal, whereby both the inner and outer parts of the metal surface are machined accordingly. Turning is done using a lathe, either simple or special. The technological part of the process is the cutting of the metal raw material, which gives the required shape and surface quality.

We can offer services of CNC lathes and universal lathes.

Automated production with numerical control enables continuous control over the dimensions of workpieces. Programmable machines provide maximum precision and shortest production time.

Milling

Milling is called machine cutting of complex shapes, where the highest level of precision and the most sophisticated not only 2D but also 3D shapes are achieved by precise vector drawings. Today, milling services are used by a variety of companies and individuals who seek precision and exceptional design. Milling services are usually provided for manufacturing purposes, where a non-traditional form of molding or a special part shape is needed.

A machine tool program can take even the most complex shapes, opening up new opportunities for your ideas.

Drilling

Drilling is the most common way to make a hole in any part. The most important element of this process is the drill bit, which is selected depending on the material and surface. 

The machine allows you to drill holes of the required diameter and depth in various fasteners, components and various metal products.

Bending

Bending is the process of forming workpiece corners or contouring. To avoid creasing and cracking of the inner contour, the bend need to be radius r ≥ 50 H.

Cutting

Water abrasive spray – waterjet

This allows all materials to be cut. The greatest advantage of this method is that the workpiece is not subjected to thermal stress during the cut, nor does it create any new stresses in the cutting area.

By laser

Laser cutting is an accurate, fast and cost-effective way to process sheet materials. Laser cutting of black steel results in a clean cut that allows the workpiece and parts to be galvanized or coated without further processing. The latest lasers also efficiently and precisely cut non-ferrous metals – stainless steel, aluminum, copper, brass or titanium.

Plasma / gas

Plasma is a gas wholly or partially ionized. Plasma cutting machines can provide an accurate and flawless cutting process using a concentrated electric arc, where a high temperature plasma pole melts and removes the cutting material from the cutting area.

Bandsaw

Band sawing is a quick, easy and inexpensive way to cut a wide variety of profiles, both solid and tubular. The bandsaw goes down with a rotating saw blade that cuts quickly and deeply into different thicknesses of metal. This type of metalworking is particularly applicable in the production of a wide range of products from black or stainless steel, aluminum, copper, brass and other materials. Blanks of required length and angle can be produced.

Circular saw

Circular sawing is a fast, easy and inexpensive way to cut a wide variety of profiles, both solid and tubular.

Choping

Cutting is the process of separating parts of the workpiece by means of various shears. 

Erosive wire cutting

Electrical erosion is a metal working method where high voltage electrical discharge is used for cutting. Wire is an electrical erosion lathe used to generate electrical discharge.

Perforation

Hole punching is done after planting tools. Continuous or blind holes are obtained. Thick forged holes are punched on both sides, thin holes on one side using pallet rings. Holes are punched with solid or hollow (> 00400 mm) punches. When the hole diameter is d ≥ 5.0 D, the workpiece is highly deformable.

Stamping

Open stamping 

 The workpiece volume is larger than the forged volume, so accurate workpieces are not required. There is a special molding groove in the partitioning plane about the outer contour of the cavity for excess metal (molding). The die stops the flow of metal from the die cavity, making it better filled. After stamping, the outlets are trimmed.

Stamping with closed dies.

Stamping using horizontal forging machines, presses and hammers. The workpiece is deformed in a matrix that contains a punch with constant spacing. This results in a closed die cavity. Forgings are pushed out by pushers at low stamping gradients or a moving matrix without stamping gradients is used.

Welding

MIG/MAG/TIG

Welding is a technological process that results in the permanent joining of parts. Welded metals and their alloys, glass, pottery, plastics, non-metallic metals, etc. Welding is a cost-effective and most important technological process for connecting ship frames, fluid and gas tanks, metal wagons, boilers, steam and hydraulic turbines. Welding reduces production waste and saves materials, for example by replacing riveted structures with welds, saving about 15-20%.

Grinding

Flat grinding

Round grinding

The grinding operation is performed when the belt or tool is rotated in the normal direction of the workpiece surface, thus providing the necessary feed. The machining area is abundantly supplied with abrasive suspension or dry sanding is possible. No micro-cracks or scorch marks remain on the treated surface. 

Abrasive cleaning

Sandblasting of metal – abrasive cleaning, so called sandblasting, allows to remove rust, paint, dirt that cannot be removed by hand cleaning such as oil stains, grease, dirt or soot.

Sandblasting abrasive cleaning of surfaces is done using abrasive materials. Abrasives are very hard materials that can be natural or artificial – synthetic.

Engraving / Marking

Metal engraving is a durable and clear way of marking many metals. Different procedures are used depending on the type of metal engraved.

If the metal has been treated or coated, the laser will engrave the top layer to reveal the underlying metal surface. The results depend on the metal used.

When engraving the raw metal, the C02 laser leaves blurred marks on its surface. If the metal is coated with a layer of a particular chemical compound and when the laser comes into contact with this chemical compound, it is trapped on the surface of the material and leaves lasting black marks.

Heat treatment of parts

Heat treatment is the process of purposefully changing the structure and properties of metals, their alloys and other materials by heating them to a certain temperature, maintaining them sufficiently, and cooling them at a specified rate. Available:

Annealing

Normalization

Hardening

High-frequency induction hardening

Release

Cementation – carbon saturation of the surface of low carbon steels

Hardness measurements of steel can be done with Brinell and Rockwell measuring tools and Ultrasonic Contact Impedance (UCI) hardness meters.

Painting

Powder painting

Powder coating is a popular and reliable method of painting in the metalworking industry. The surface of the metal part is coated with a special electrospray powder by a special spray. When exposed to electromagnetic forces, they adhere to the metal surface in a uniform layer. The powder coated parts are placed in an oven heated to 170 – 200 ° C. Depending on the thickness of the metal and the properties of the paint powder, the product is kept at this temperature for 10-30 minutes. At high temperatures, the powder melts and covers the metal surface with an even layer of 0.04-0.120 mm.

Wet painting

Wet painting is performed using high pressure airless equipment. Before painting, the products can be coated with various additional layers, eg anti-corrosion. Professional operators apply a thin coat of paint without leaks or drops.

Wet painting is commonly used for products that cannot be heated, cannot be disassembled, and thus do not fit into the furnace, for small and simple painting jobs where powder coating is not required. Also, if a color is required that cannot be obtained by powder coating.

Assembly and Packaging

Possible assembly of components and components into the final product. Upon customer’s request, assembly is done on time. The aim is to collect the maximum quantity of products in the shortest amount of time. Specific packaging solutions are available according to the customer’s wishes.
