Jyoti Engineering Works specialises in the production of marble block dressing, chainsaw, diamond wire dressing, diamond gang saw machines and hydraulic jacks. The chainsaw machine is a very useful machine in entire mining operations. It can be used for developing the mining floor, cutting and excavation of blocks. The machine is used for marble quarrying with tungsten carbide tools. It is able to cut as long as desired in a single cut by just replacing the rails without the machine advance to be interrrupted. Vertical and horizontal, both type of cutting can be done with the machine. Heavy rail lines, which give more stability to the machine, result in accurate cutting of stones. Standard components of the machine like gearboxes, pumps, valve, electric motor and heat exchanger are of well-known make. The rotation of the arm holder is by means of hydraulic cylinder and lockings system in both cutting positions horizontal and vertical.
