Model MC1763F3 is a multi-purpose horizontal lathe with numerical control.
The machine implements technological processes for the complex processing of parts such as bodies of revolution, i.e. it is difficult to perform turning, milling, drilling and threading operations with minimal energy consumption from a single installation on a part.
The basic assembly unit, on which all other units are mounted, is a bed – a horizontal cast iron rigid box-shaped body, on an inclined plane of which two roller guides for the cross support are mounted, and below – two sliding guides for the tailstock and steady rest. On the left end, a gearbox with an electric motor of the main movement is mounted, and on the right end, a horizontal feed drive of the cross caliper.
The machine is equipped with a 12-position DUPLOMATIC electro-hydraulic turret with a rotating tool.
When processing long shafts, only the rear center is not enough, but additional support is required, the role of which is performed by the SMW-AUTOBLOK hydraulic steady rest.
For high-precision adjustment of the cutting tool before starting work and wear control during processing, a precision motorized arm from RENISHAW is installed.
To remove chips from the processing area into the Customer’s container, a lamellar chip conveyor is used. An integral part of the conveyor is a tank with a cooling emulsion and a pump.
The machine is provided with a cabinet fence that closes the cutting area and protects against splashing of the emulsion and scattering of chips. All guides of the machine are covered with telescopic protection.
