MORI-SAY 657AC, 667AC
Multi-spindle automatic lathes MORI-SAY 657 / 667 AC
Numerically controlled automatic lathe Mori-Say 657 / 667 AC is the new machine conceptually congruent with the series of the TAJMAC–ZPS multi-spindle automatic lathes. It is intended for the mass and series production of the precise components from the bar stock.
The machine is manufactured as fully mechanical with regulation sliding and spindle engine operand by programmable automat. The machine can produce also two various parts and work as twice three-spindle.
The machines MORI-SAY 657 AC and MORI-SAY 657 SAC are intended for production of machine parts from bar stock with the maximum length of 4,000 mm with the diameters to 57mm and hexagons to 50mm. The ends of bars must be chamfered at least at 1.5 x 65 degrees (vertex angle – 50 degrees). Admissible tolerance of both circular and non-circular cross section of a bar clamped in the collet bush is within IT 11 tolerance. The bars must be straightened of 1 mm on length of 1,000 mm.
The bar surface should smooth, glossy or matt, free of laps, non-metallic inclusions and scales,mechanical impurities and signs of corrosion. Only isolated defects – grooves, impressed hollows, marks from blasting and straightening and cleaned spots are acceptable.
After additional installation of the optional equipment, the machine can produce also two different simple parts – it operates as a double three-spindle machine.
The machines MORI-SAY 657 AC are manufactured in basic versions full mechanical with variable speed of feed and spindles motors control by programmable device with various number of numeric option and will adapt to various types of collet´s.
