MACHINES MODEL EZ 207, 
Universal automatic gear shapers are intended for cutting cylindrical gears with internal and external gearing under conditions of single unit and large scale production. The machines are vertically arranged. Special machines for mashining helical gears, toothed sectors, pinion shafts, gears with angle of friction 12 degrees can be manufactured by a special inquiry on the basis of machine tools of model

ADDITIONAL ACCESSORIES
Hydraulic clamp
Follow rest
Steady rest

Semi automatic spline hobbing machine is intended for hobbing straight sided shafts and involute splines as well as teeth of the cylindrical gears, both spur and helical, in large scale and single unit production conditions. The work spindle has a through hole of 90 mm diameter. This makes it possible when using a jaw chuck to install workpieces of a much bigger length than between centers up to 2000 mm and more.

ADDITIONAL ACCESSORIES
Hydraulic clamp.
A complete set of change gears for machining simple teeth.
GENERAL
Universal semiautomatic gear hobbing machines are intended for hobbing cylindrical, spur, helical and worm gears under single unit and larger scale production conditions. Rolling of the hob and the workpiece carries out a gear cutting. The semiautomatic machines operate on a closed cycle and on a adjustment cycle.
Semiautomatic machines have a stationary table and a movable column. An important constructional features of the semiautomatic gear hobbing machine model are availabilities of inechanisms allowing to carry out hydraulic clamping of the crosspiece and arbor support arm vertical motion of arbor support arm during a work cycle. Semi automatic machines have a stationary table and a movable column. The machines have a universal
hob slide, which makes it possible to hob cylindrical and worm gears by method of radial in feed and tangential feed. On the basis of models there can be made the machines model for hobbing periodical profile rolls for armature rolling on mills.
ADDITIONAL ACCESSORIES
Knurling worm grinding wheels
Diamond cutting tools for worm grinding wheels dressing.
Diamond pencil
Device for worm grinding wheels dressing with diamond rollers.
MACHINE MODEL
The semiautomatic gear grinding machine is intended for grinding cylindrical spur and helical gears in single unit and largescale production. In comparison with other methods of gear grinding by means of profile wheel with single indexing, with disk type and cup type gear wheels by generation method with single indexing and etc. The method of continuous generating permits to make the productivity 4 to 5 times as high. Dressing of single start and double start worm wheels with multiple start
and single start crusher tools and diamond tools is carried out on the machine.
OTHER MACHINES
Gear rounding machine model
The semi automatic machine is intended for teeth butts curving of external toothing cylindrical gears and of internal toothing spur gears. Machine for cylindrical worm gear shaping model. The semi automatic machine is intended for shaping of cylindrical worms, spiral gears and special screws. Workpiece machining is carried out with a cutter by gear sharpening method. Multi spindle gear cutting machine model. The semi automatic machine operates with milling and gear cutters by automatic single indexing method. The semiautomatic machine can be adjusted for one of the following operations rough machining of taper and cylindrical spur gears disk teeth of turning chucks teeth of star wheels jaw and tooth type clutches front slots and polyhedrons drill bits cutters collets slots teeth of disk saw sections short racks cutting of various shape workpieces. It is possible to machine two or three workpieces simultaneously. The semi automatic machine has a two position rotary table. When the table is in one position, workpieces loading and unloading is carried out, when in another position automatic cycle machining. This makes it possible to save time.
