The CTV 160 vertical lathe from Gildemeister,
making its American debut at IMTS, is designed for mass production with a small
footprint on the one hand, and universality for the shop floor area on the
other.
"When deciding on an investment, high production companies are interested primarily in cost-per-unit productivity and floor space requirements of the workshop facility. The universal machinist, however, takes other aspects such as ease of operation, programming and tooling into consideration in addition to the cost of investment. To date it has proven difficult to reconcile these very different requirements in the field of vertical lathes. Often, speed was achieved at the cost of flexibility. Universality was consistently given preference over productivity. The presentation of the new CTV 160 has reduced this scenario to a thing of the past. Because of short chip-to-chip times and optimum turning performance, the latest vertical machine from Gildemeister Drehmaschinen GmbH not only offers fast production times, it also offers the framework for flexibility on the shop floor due to accessibility and user-orientated control technology," said a DMG spokesperson.
Productivity is achieved by the option of moving the Y-axis out of the working area and placing in it the area of the traveling column. The ability to move the Y-axis from the work area means that all motion axes are now located on the side of the workpiece spindle. This makes it possible to expand the travel path of the Y-axis to ±90 mm, increasing the flexibility of applications of the machine for off-center drilling and milling. In combination with the long Z-axis, it is now possible to process a wide range of shorter and longer workpieces of between 20 and 180 mm and with diameters of 160 mm, with no need for time-consuming retooling.
"The criteria of universality was not the main focus of interest for "moving" the Y-axis as Dr. JŸrgen Walz, Managing Director at Gildemeister Drehmaschinen GmbH, explains: "The main aim here lay more in reducing idle times. In this respect the higher position of the large Y-axis means that the machine is now able to place a machined workpiece onto the transport belt using a pick-up-principle and to move to the next unmachined part, mount it in the spindle and move back to the machining position without any loss of time whatsoever. In combination with the fast X-axis we now achieve chip-to-chip times of less than 5 seconds."
The floor space requirement for the CTV 160 is
only 4.7 m2. Feeding of the workpieces is carried out via a round table with 20
stations for workpieces of lengths ranging from 20 to 200 mm, diameters of up to
160 mm and weighing up to 8 kg. The 'intelligent' height adjustment allows
simple adaptation of the table to fit different workpieces.
As an example of continuous operation, Dr. Walz discussed the use of large size 45 guideways as the basis for maximum process stability under tough day-to-day production conditions. "Moreover, there are no longer any axes to be found in the lower work area where chips fall, this adds primarily to process reliability but would also simplify possible maintenance or service work respectively."
The chip conveyor can be placed either to the side or in the rear area of the machine. This allows for the possibility of installing two identical CTV 160 machines directly beside each other and using one workpiece magazine with a turning station, thus combining them into one manufacturing system for complete machining in mass production. In this case there is also the additional option of installing an extra buffer belt for parts on the rear side of the machine.
"The CTV 160 may be of interest to universal machinists because of the adapted DMG ERGOline Control with its 19"-screen and integrated ShopTurn programming system that guarantees the quickest way from the unmachined workpiece to the finished product," said a spokesperson. "The CTV 160 has a wide-ranging spectrum of applications, for the smallest job shop right through to applications in the automotive industry and its suppliers. The CTV 160 being presented at IMTS is the start of a whole series of new vertical lathes to be offered by DMG."
