CNC Internal Grinder STG-6N
It is a space-saving CNC internal grinder that realizes the equipment width of 1,600 mm while supporting 6 inch chuck. Workhead spindle is equipped with a 6 inch scroll chuck to cope with the expansion of the work size which was requested so far. Wheelhead spindle realized high precision and high efficiency grinding by installing our own High rigidity spindle SSPG-045 T100. Efficiency improvement and reduction of workload of operator can be attained by making machine configuration and layout considering workability and operability.
