T-184C Large-size Vertical Grinding Machines, Chuck Type

Installation dimensions of this large machine are 5,300mm (width) x 4,600mm (length) x 4,350mm (height). Enhancing overall rigidity of machine, hydrostatic bearing that has high rotating accuracy and permanent electro-magnetic chuck are adopted to workspindle. These enable to process works up to 1,250mm OD, 400mm width and 2,000kg weight stably with high-accuracy. Further, newly developed high-output (30kW) and high-rigid high-frequency wheelhead is employed. Incorporating auto-balancer and AE sensor, rotating unbalance using large-diameter wheel is corrected in the wheelhead automatically, and high-precision and high efficient machining can be achieved.

T-185C,T-186C,T-187C Large-size Vertical Grinding Machines, Chuck Type

Installation dimensions (width x length x height) of T-185C are 5,600mm x 4,500mm x 5,470mm with 1-table specification, and 7,100mm x 4,500mm x 5,920mm with 2-table specification (T-185C-2T). Max. work size of both models is 1,600mm in processing diameter and 2,000kg in weight. Dimensions of ultra-large T-186C are 9,030mm x 5,000mm x 5,920 mm and max. work size is 2,600mm in processing diameter and 5,000kg in weight. Dimensions of largest T-187C are 7,550mm x 6,800mm x 5,250 mm and max. work size is 3,500mm (4,000mm with special specification) in processing diameter and 5,000kg in weight. All models adopt hydrostatic bearing that has high rotating accuracy, and high-rigid and high-output high-frequency wheelhead exclusive to ultra-large vertical grinding machines (30kW output with auto-balancer and AE sensor), highly reputed in the use on T-184C, realizing high-precision and high-efficient processing.
