The advantage of the Marovt company is that forged parts are machined in our own forge. This is why we are able to ensure forged parts with characteristics defined together. The machining of forged parts is mostly automated; therefore, the human factor is decreased and permanently the same technological process can assure all parts to be machined in the same way and being controlled and tested according to the same procedures.The machining of forged parts is carried out on technologically advanced 3 and 4-axe machines. Our machining centres have the possibility of using up to 40 changeable cutting tools. The tool can be up to 300 mm long and up to 10 kg heavy.The machining center spindle can rotate up to 20,000 rpm. Changing the cutting tool at our centers only takes 1.7 s, which greatly shortens the machining time. All our machining centers have a pallet system that eliminates the time of mounting the forging parts into the clamping device.

The Mini Shaft Loader allows you to load short shafts. The loading is done automatically. Do you have remnants of long bar feeder and would you like to process them? Or do you want to load very short shafts automatically? The MSL is the ideal complement for the Multi-3000 to load short shafts. It has a multi-profile loading prism. So you can load round and hexagonal material and all this without changing channels. Special profiles are possible on request. Impact-free recharging thanks to the exclusive recharging cycle. The recharging cycle is based on the patented recharging mechanism of the Multi 3000. After fast and precise bar removal, the material is gently placed on the loading prism. The Mini Shaft Loader is connected to the bar feeder. This takes over the power supply and control of the loading system. The material is fed via the slide of the loading magazine.

ar feeder for special profiles wanted ? To extend the MULTI 3000 to the bar feeder for special profiles, the Uni-erector can be mounted optionally. It enables the erection of rectangular profiles and special profiles for further transport to connected machine tools. Thus a smooth reloading process is possible. By simply setting a parameter, the erector can be selected or deselected. This enables a quick changeover from round material to a special profile. By deactivating it, the bar loader can load round or hexagonal material as normal. While with activated parameter the bar feeder will load the special or rectangular profile while the reloader is erecting. The use of square material is also optionally possible. The erector consists of two opposite rollers. To erect the material, these rollers move together during reloading. When the bar is threaded into the machine tool, the rollers open again. The distance between the rollers can be easily adjusted.

SAMSYS offers Spindle Liner for draw tube diameters from 38mm to 100mm. The length of the reduction tube depends on the length of the draw tube, as well as the clamping device and the type of clamping cylinder. The reduction tube consists of a precision steel tube as support tube (1). In order to ensure optimum guidance, the rear (2) and the front (3) guide are adapted to the lathe. Mounting as well as dismounting can be done in a very short time with a few simple steps, as the reduction tube is only attached to the clamping cylinder with two screws. The POM bushings (4) can be flexibly adapted to the material diameter. Since you do not need to store a reduction tube for every diameter, you save valuable storage space. A Water pan extension (5) is also available as an option for safe covering and splash protection.

The AutoSAM 3.26 is an automatic bar feeder with hydrodynamic bar guidance. It is particularly suitable for connection to sliding headstock lathes (Swiss-Type). Its field of application is in small, medium and large series. Its big brother is the bar loading magazine AutoSAM 3.51. The bar feeder has a calibration-free material clamping which is carried out by collets. This saves time for material change due to the automatic centric positioning. Four clamping jaws ensure maximum hold while the collet is being pulled onto the bar. The Mitsubishi PLC control system with PC board ensures extreme process reliability and simplifies communication with the lathe. Compatible with almost all types of lathes. For example Citizen, Star, Nomura, Mazak, Okuma, DMG Mori, SMEC, Doosan, Nakamura, CMZ, Takamaz and many more.

The spindle extension SamSpindle, has been specially designed for the extension of lathe spindles. Together with the bar feeder Multi 3000 it forms a safe, clean and efficient solution. The SamSpindle operates oil and air free. There is no mechanical connection to the lathe. Only a minimum of moving parts and masses. These are: the rotating bar, the guide rings and the inner cage of the ball bearings. The guide rings mounted in the roller bearings keep the bars in the centre of the SamSpindle cartridge. Thanks to this technique, round or test bars can be rotated at high speed, ensuring remarkably smooth running. You can turn drawn, round or profile bars, with correct straightness, at the maximum spindle speed of the lathe. This allows us to guarantee workpieces with high precision. The SamSpindle spindle extension offers maximum safety. It does not allow access to parts in motion. The moving parts are all enclosed in the SamSpindle cartridge, which is closed by a safety nut.

The basis of short bar loader Multi 3000SL was developed in Switzerland. It was specially designed for turning machine types with a large distance between machine cover and spindle end.

Sheet metal handling and lifting steel plates with vacuum technology. Both magnetic and non-magnetic sheets are easily lifted. The suction pad is placed on the metal product, after which the vacuum is activated by a push on the button. Now you can lift, move, or even turn the sheet metal. Vacuum lifting is used during production, storage, internal transport, transhipment, and construction. Besides vacuum lifters for metal plates, we also design pipe handling equipment. All our designs are custom made to perfectly match the individual situation. Why choose lifting plates by vacuum? Vacuum offers unique advantages compared to other lifting methods to lift plates, such as chains, clamps, and magnets. Chains and clamps can be used to lift non-magnetic plates, such as aluminium, copper, and stainless steel. Compared to these lifting methods, vacuum offers distinct advantages: No damage to the plate, not even scratches No spacers or stoppers required Easy and fast handling Less manpower

Cut-to-length lines for T-shaped panels Slitting and recoiling lines with automatic separators positioning Dedicated plants for pre-painted,? film-coated or other special materials (stucco-design, mesh, ground surfaces…) Special lines for panels production, with punching, shearing, roll-forming and bending Continuous punching lines Spool recoiling lines De-burring lines Combined lines with partial cut, where a part of the strip is recoiled for future use Machines for mass production or very flexible plants for small productions Cut-to-length and recoiling lines, with coils packaging stations. Customized and very enhanced productions, which integrate the sheet-metal processing with rotating turret punching (possibility of up to 24 different tools? a time, even in “multitools” solutions) or fiber laser cut.

Combined cut-to-length and recoiling lines, that decoil, straighten, cut and recoil various kinds of sheet metal. They are suitable for coils of sheet-metal of any kind and with max thickness 4 mm. The results are parcels of blanks that can be piled-up with a stacker and recoiled strips of different widths, even obtained by partial cut. Our plants are provided of remote assistance equipment, to guarantee precise and immediate interventions, to modify the software parameters and quickly solve emergencies and stops of the machines.

Each line is carefully designed on the customers indications, starting from a general structure that is as follows: Coil car, motorized and with hydraulic lifting Decoiler, designed on demand and with the required capacity (up to 30 ton) Straightening group with one of the different precision straighteners or levellers we can propose. We have in our range also “cassette-system” levellers, for the quick exchange of the working rolls. They are particularly useful for those who have a big range of materials and thicknesses. Guillotine shear (start-stop or non-stop models) or flying shear. This last one allows the flying cut of the sheet-metal, without stopping or slowing down the passage of the material. The shear moves synchronized with the metal strip. The control equipment checks the material movement and automatically decides, according to the speed, to move the car that holds the shear.

It is a special slitter with Numerical Control, different from all the others available on the market, with a variable number of slitting heads, which include in one single body the upper and lower blades. This allows to easily adjust the clearance between the blades (now also automatically) and to reduce the wearing. The characteristic that makes this slitting group original and extremely efficient is the system of changing the slitting widths, without manual intervention of the operator. The slitter can be managed by N.C., so from the line control-board, by remote control, or even by a PC interfaced to our customized softwares: GA.GE. or GMDesign.

It can be completed by many options (scrap-coilers or scrap-choppers, film or protective paper applicators…) and with devices to help the coils loading and unloading: coils cars, rotating arms, rotating tables for the automatic strapping, magnetic lifting systems, conveyors and so on… They are all studied together with the customers, following his needs and preferences.

HPM Breeze is the consequent development of the common CL-, MQL and MQCL-procedures. Fluids will be checked during the production process and applied in a certain amount at a certain time and at a predetermined location. The HPM Breeze-procedure is extremely fine with an aerosol that adheres like a dense fog around the working area. HPM Breeze forms a completely closed and highly lubricating film. Where previously many litres of liquid were necessary it is now a small fraction thereof which suffices. The HPM Breeze process is used to lubricate and cool machining processes with extremely small quantities of cooling lubricant. An air-fluid mixture that prevents the development of frictional heat with optimal lubrication is employed for this purpose. The remaining heat is dissipated with the swarf. The LSJ Z35 is offered in 2 versions. 10 bar is standard. For more demanding applications, the LSJ Z35 is available in a version with 16 bar.

Our Breeze technology has many enormous advantages over the previous classic lubrication applications. Discover enormous savings potential for mass production when using our LSJ Mini in your process. This system can be used optimally in the event of always consistent tool operations. For the machining process, an average of between 5 and 50 ml of lubricant is used per process hour and tool. These consumption values can also be briefly — depending on the requirements of the individual operation — increased to up to 200 ml per process hour. In addition to this excellent advantage over the previous method, the HPM Breeze method offers further enormous advantages from an economic and ecological point of view. • For optimum use with a cooling channel diameter of 0,9 mm² and up. • Manual adjustment of the pressure parameters • Optimally suited for consistent series processes with one parameter
