"With the help of our rich machine park and well-experienced engineers, we can answer your custom design machine part needs. Please don't hesitate to ask for the price."

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.
