Four m technology manufactures 4mhydroslot-400 which is the latest generation innovation in slotting technology. These models are constructed in entirely new concept of coupling mechatronics and hydraulics catering to the needs of medium and heavy machine tool and heavy automobile industries. This machine model is able of slotting 6 mm to 45 mm[in steps] keyways 320 mm long with high quality, reliability, productivity and process automation to the industry. This machine is available with ram which operates with 400 mm stroke hydraulic cylinder and 15 mts/min variable speed control to make easy slotting of all materials and cutting tools. This unique feature of the slotting macine can also be used for broaching operations. The ram stroke adjustment can be made adequately by limit and safety cut-off limit switches, mechanical safety stoppers, electrical safety interlinks for maximum safety of operator, job and machine. These slotting machines come with advantages of having 650mm diameter extra large rotary table, accurate indexing mechanism, rotary encoder and dro display ensuring accurate angular division for multiple slots and spline slotting. An ac servo drive and ground ball screws with zero back lash automates cutting feed and gives fine cutting feeds of 50 microns per cut. This machine is totally plc controlled and incorporates tool relief cycle during return stroke of ram for enhancing tool life and fine slot side surface finish. These traverse movements of the 4mhydroslot-400 are on hardened, ground rectangular guides with stick free turcite and auto-lubrication. The machine comes well equipped with 2 linear scales and 1 rotary encoder with digital read output display for monitoring and controlling the slot dimensions accurately. The man-machine interfacing system ensures easy programming and well- designed ergonomics of the 4mhydroslot-400 machine makes it user friendly and fatigue free. This 4mhydroslot-400 machine is available with technical specifications such as 8 mm- 45 mm [in steps] slot, 10 microns slot width tolerance, 50 microns slot depth, 25 microns slot in centre, 320 mm slot length, 1000 mm job size with fixture and 0.025 degree [dro] indexing accuracy.
