Mitsui HSG-818TEC CNC Precision Grinder - Highlight of New Features The MITSUI CPU control allows you to converse with the system by entering numerals to the menu screen. The crossfeed and longitudinal feed reversing position can be set by programming, making manual stops unnecessary. Grinding cycles are performed in the manual feed, creep feed, or standard feed modes. Point-to-point stepped grinding and unequal pitch indexing (lengthwise and vertical directions) are possible in the creep feed or standard feed modes. Climb grinding is also' possible. The operation system's design is based on thorough simulation and ergonomics For stable, high grinding accuracy, the newly designed high-rigidity, dual box frame is constructed by at least 3/4" thick meehanite castings. The spindle is equipped two sets of high-rigidity bearings. Since the vertical guide has no gap, forming and grooving are free from head raising, thus ensuring high grinding accuracy. The longitudinal feed mechanism uses the cross roller bearing system to allow load in every direction. It is characterized by excellent vibration and shock resistance, and allows side grinding. , The longitudinal feed mechanism is driven by a precision ball screw assembly and AC servomotor to be completely free of dislocation in reversing positions. The grinding efficiency, therefore, has been greatly improved. The pre-loaded roller guides along all axes allow no gaps and on stickslip movements. The crossfeed carriage is designed to have no overhang, which will allow high accuracy grinding. The linear scales are mounted as close as possible to the leads- on the "X" and "Y" axes to make accurate reading. The inverter, speedmeter, and load meter are provided as standard equipment to inform the operator of the grinding conditions during operation. Three way coolant nozzle assembly is provided as standard equipment. The maximum movement is 8.2" (210 mm) along the "X" axis, 20.4" (520 mm) "Y" axis and 15.3" (390 mm) "Z" axis. Magnetic chuck capacity max. is 8" x 18" (200 x 450 mm). The machine is furnished with manual hand wheel assembly on all Three axes for manual operation. Leadscrew assemblies and guide ways are protected by bellows. The operator panel is equipped with a flat keyboard and is completely dustproof an-do waterproof. Since the system has no hydraulic mechanism, it is free of vibration and thermal influence. The leadscrews and guide ways are automatically lubricated. Standard 3 HP spindle motor can be upgraded to 10 HP or a 1.5 HP air spindle assembly.
