The rigid construction of the machine and the high motor power of 15 kW, the wide range of spindle speeds and high top cutting speeds allow to rationally choose the machining parameters and perform the machining of different materials.
The TUR lathes, owing to their modern solution of the spindle supporting and the application of high-precision angular contact ball bearings, and the TUR 630A/ 710A as double chuck machines with a bigger spindle bore and spindle supported in special, rigid bearings, allow to achieve the best surface finish.
The gears and spindle box made to high-presision standards ensure the accurate operation of the machine tool. The TUR lathes combine a rigid structure with high motor power and a wide range of spindle speeds to enable roughing and finishing all types of steel, cast iron, non-ferrous metals and plastics.
Transverse or longitudinal feeding
The carriage contains a transmission system which allows transverse or longitudinal feeding, either manually or mechanically. The rapid mechanical feed can also be used in both directions when the lead screw half nut is disengaged (The transverse feed is geared to 1/2 the rate of travel of the longitudinal feed.).
21 spindle speeds
The headstock contains the main motor, the speed transmission and the feed and thread transmission. The head stock drives the spindle and contains the speed selection transmission which provides a range of 21 spindle speeds. The main spindle is powered 15 kW motor. The tailstock travels along the two bed slideways. The tailstock is easily positioned by carriage and connection is with a quick-disconnect coupler.
The lathes are capable of cutting right and left-handed threads in all standards: inch, modular and diametric pitch units.
