CNC vertical lathes SM1736F3 and SM1756F3


CNC vertical lathes are designed for:

  • rough and finish turning in the chuck of the outer and inner surfaces of parts with rectilinear and curvilinear generatrices (such as discs, hubs, cups, flanges, gears, flywheels, etc.) in several passes;
  • turning external and internal threads, spirals at the end.

The design of the machines is characterized vertical spindle products with the following advantages:

  • clearly accessible and clear working area, ergonomically favorable for manual loading and tool change;
  • simple clamping of the workpiece as it rests on the base surfaces due to its own weight;
  • no deflection of the work spindle due to its own weight, the weight of the workpiece and the chuck;
  • convenient loading and unloading of heavy workpieces with the help of small-scale workshop tools due to the calipers set at 120 ° horizontally and the absence of fencing elements above the chuck with the doors open;
  • small footprint;
  • Low installation costs as no special foundation is required.

HIGH PRECISION in long-term operation is achieved due to:

  • vertical spindle;
  • rigid thermosymmetric machine design;
  • automatic lubrication system;
  • position of guides outside the chip flow zone;
  • separately located heat sources – hydroelectric power stations and electrical cabinets.


  • parallel use of two freely programmable cross calipers with 4-position turrets and highly dynamic feed drives with ball screws;
  • stepless main drive from a powerful asynchronous electric motor with frequency control;
  • spindle headstock with automatic switching in the cycle (according to the program) of the pre-spindle block, providing two ranges of power characteristics;
  • oriented spindle stop for easy loading of asymmetric parts;
  • the ability to quickly switch from processing one part to another;
  • the presence of a device for setting tools outside the machine

AUTONOMY OF OPERATION is ensured by the presence of:

  • own coolant system (tank,   pumping station, filters);
  • two 2-screw chip evacuators capable of removing a large amount of “uncomfortable” chips from the cutting zone, which are formed during the processing of ductile alloy steels;
  • systems for separating coolant from chips.
