Ryazan 16R 25 RF3 horizontal cnc and converntional lathes

Ryazan 16R 25 RF3 horizontal cnc and converntional lathes GERT RYAZAN MACHINE Oil 
Horizontal CNC and conventional heavy duty Ryazan lathes 
The Ryazan lathes are designed for chucking and between centers turning of cylindrical, stepped, or contoured workpieces, as well as thread cutting. The machine's rigidity and their technical characteristics allow for full use of advanced cutting tools for machining work pieces made of ferrous and non ferrous metals. Design features wide bed hardened and ground three prismatic guide ways, double Vee ways or box shaped ways, rigid, vibration proof and temperature resistant design provides high machining accuracy, stability, and working life long taper turning is defined by simultaneous longitudinal feed of the carriage and cross feed of the slide swiveled at a certain angle all gears of the kinematic gears are made of alloy steel, hardened and ground quick and cutting zone protective screens as well as electrical and mechanical lockouts ensure safe operation on the lathes. 
Lathes are CE certified Heavy duty lathe used for big parts machining might be equipped with a pass through carriage. Heavy duty lathes are used for machining of heavy forged shafts, drums, etc. The lathes may be equipped with special grinding or milling devices and C axis for fine machining of cylindrical and conical surfaces.

The machines are intended for machining of forged and hardened steel shafts and rolls. Rough and finish machining of shaft barrel and necks, cutting of new and repair of used grooves. The machines are produced with one or two carriages, equipped with rests for cylindrical and conical shaft necks. The machines with CNC are supplied with special software for sophisticated applications. The machine model is intended for machining of rolls for reinforcing bar production. Machining of the roll goes through three stages roll turning, roll grooves calibration tool holder is set on the carriage milling, groove cutting in the roll passes by special tool holder marking, text engraving in passes marking device is set on the carriage.

A number of technical varieties on the base of standard modules
Only modern, reliable and high production deep hole drilling and horing machinecan provide high quality machining of the holes. Deep hole drilling and boring machines of Ryazan Machine Tool Plant Company meet all the user requirement. These special machines are of different sizes and versions in desing. The following structures may be used Construction type lathe type machine
Rotation workpiece in clamped in the headstock chuck and rollers rest. The boring bar with a tool is fixes in the boring bar headstock. Effective methods of machining provide high quality

Special methods of machining are used to meet the user requirements. These methods greatly decrease the technological time of operatıon.
Methods of machining
Solid drilling
Drilled material is removed like chip.
Drilling diameter is.
Ring type drilling
It is used to drill holes with diameter from 80 mm to 500 mm. Annular space is drilled out with small power at cutting. The drilled core is possible to use. Boring
Rough and finish boring is used for machining of castings and drilled holes. It is necessary to observe the requirements of hole axis location, its straigh ness, precision of diametrical sizes and surface roughness. Extracted foring
It ensures accurate location of hole axis and it is used for parts where it is necessary to provide equal thickness of walls.
Rolling
Rolling is used as an additional operation if it is necessary to have smaller tolerances and higher surface quality than those in above mentioned methods of machining

High quality drilling is possible only at the continuous removing of chip from cutting zone. What is more, at cutting the operation influences greatly on the tool life. Both factors require high production coolant unit with a big capacity tank and powerful pumping equipment. At drilling the machine operates with outside supply of coolant and internal removing of chip BTA method.
Coolant is supplied between boring bar and workpiece wall to the blade. Mixed
coolant with chip are eliminated through internal cavity of drilling head and boring bar. The contact between finshed surface and chip is avoided. lt provides a highquality surface. At boring the method of outside retractionis very often used. For this purpose, the workpiece hole is used. This hole is made by previous operations.
Coolant with chip drains into chip collector. Coolant is returned into general tank through the chip collector. the cycle is finished.
