THE CONCEPT

EMCO is a European company represented throughout the world. The EMCOMAT 17/20 machines are based on many years of experience in mechanical engineering. Nowadays higher demands are placed on precision and performance, ergonomics and design. EMCO developed the new lathe series EMCOMAT 17/20 to satisfy these requirements, all are designed  to toolmaker accuracy to DIN 8605.

EMCOMAT 17 S: Distance between centres 700 mm, centre height 170 mm, spindle bore 50 mm Dia, 8 spindle speeds from 55-2350 rpm, brake motor with automatic release, 2.4/3.2 kW drive rating.

EMCOMAT 17 D: Distance between centres, centre height and spindle bore dia is the same as the EMCOMAT 17 S; 4 spindle speeds from 40~3000 rpm, electronic infinitely variable with digital speed display, 4.0/5.3 kW drive rating. Integrated digital read out in 3 axes.

EMCOMAT 20 D: Distance between centres 1000 mm, centre height 200 mm, spindle bore ~ 50 mm, 4 spindle speed ranges from 40-3000 rpm, electronic infinitely variable with digital Speed display, 4 0/5 3 kW* drive rating. Integrated digital read out in 3 axes.

THE USERS

Any one of the EMCOMAT models is ideally suited for the various fields of application of conventional lathes in this size range.

SMALL BATCH MANUFACTURE EMCOMAT 17 D, 20 D

Here, the automatic spindle brake, the electronic infinitely variable speed control, mechanical and pneumatic collet chucks the high drive efficiency and the special functions of the position indicator "6 tool memory" are of particular importance

REPAIR AND MAINTENANCE EMCOMAT 17S and 17 D. Easy to operate, exemplary ergonomics and low demands on maintenance are the plus points here.

PROFESSIONAL TRAINING

nowadays demands real production machines. The integrated digital display and the electronic infinitely variable speed control create a useful link to CNC technology.

THE INTEGRATED DIGITAL READ OUT

The EMCOMAT 17/20 is the first conventional lathe series in which the digital read out has been fully integrated. The control panel is mounted on the tool slide and is thus ideally positioned for the operator.

The result is maximum convenience and safety. The measuring transducers are protected against dirt and damage and all cables are covered.

Small batches are produced more economically with the digital read out and idle times are reduced. You can work with absolute or incremental systems of measurement, with radius or diameter entries, and in millimetres or inches, and zero points can be set.

The EMCOMAT read out stores the dimensions of six tools as well as eight reference and contour points.

THE SPECIAL FEATURES

CONVENIENT OPERATION
All levers and tables are arranged at optimum height, the control panel is integrated in the longitudinal slide

HIGH EFFICIENCY
3-shaft concept, high torque at the spindle through 4 gear stages.

HIGH PRODUCTIVITY
Reduction in idle times through the special functions of position indication, spindle brake, Camlock spindle nose to DIN 55029 5-5, spindle bore dia 50 mm.

OPTIONAL EXTRAS
Mechanical and pneumatic collet chuck facility, quick-change tool-post and VDI-30 toolholder system, coolant supply direct to the tool cutting edge, wedge-type chuck, hollow spindle stop.

HIGH PRECISION
Adjustable high-precision bearings of the main spindle, main spindle diameter in the front bearing 70 mm, 3-point support of the machine bed on the machine body, vibration and running-noise-damped machine base, toolmaker precision to DIN 8605, hardened and ground guideways.

PARTICULARLY EASY INSTALLATION

The EMCOMAT 17/20 machines have a 3-point bearing system which is why they require minimal foundations. Even levelling of the machine is superfluous.

THE MAIN DRIVE RATING AND CUTTING DATA

EMCOMAT 17 D/20 D; MAIN MOTOR DRIVE RATING AS A FUNCTION OF THE MAIN SPINDLE SPEED.

The graph shows the available drive rating of the main motor as a function of the main spindle speed in the 4 mechanical gear stages. The full motor power of 5.3 kW is available at every speed owing to the 4-stage gearbox. The constant power throughout the entire speed range produces a torque curve inversely proportional to the speed. At a constant cutting speed the available torque thus increases proportionally to the diameter. The positive effect of this is that the same cutting forces are produced at every diameter. The wide speed range of the drive permits both easy turning of large workpieces and the use of high cutting speeds.
