Giewont Vertical Lathe

EV-35 “Giewont” by AFM is a vertical CNC lathe. It is a pioneering solution designed for high-performance and precise workpiece processing.

This advanced innovative lathe is intended for the comprehensive machining of short workpieces of the bushing – disc class thanks to the 8-position tool head.

Vertical lathes have been made possible by the use of an integrated main drive (electro-spindle). This solution allows for increased torque with a large spindle speed range of 25 ÷ 3200rpm.

Application

The vertical lathe Afm “Giewont” was designed on the basis of over 40 years of experience of the manufacturer in the construction of machine tools. It is a pioneering solution of a vertical lathe designed for highly efficient and precise machining of details.
CNC vertical lathe “Giewont” is designed for comprehensive machining of short workpieces of the sleeve-shield class thanks to the use of an 8-position tool head.

Design assumptions of the lathe

Building lathes in a vertical configuration has become possible thanks to the use of an integrated main drive (electro-spindle). This solution allows for obtaining an increased torque with a large range of spindle speeds of 25 ÷ 3200 rpm.

The technological capabilities of these lathes are as follows:
1. During X and Z axis control you can perform:
• axial and radial turning of objects with simple or complex shapes on external and internal surfaces,
• machining holes in the axis of the workpiece, cutting external and internal threads.
2. When controlling the C axis, it is also possible to perform:
• milling of planes, cams,
• machining of holes arranged radially or parallel to the axis.

One of the most important characteristics of the “Giewont” vertical lathe is its compact, modular structure, ensuring absolute rigidity, and speed in adapting the machine to changing production tasks, i.e. quick changeover to new workpieces in small series, which in the case of horizontal lathes does not is always possible.

The dimensions of the device allow it to be placed in virtually all conditions, which also gives it an advantage over traditional lathes. The use of the control of the largest manufacturer of controls in the world, the Japanese company FANUC, the 0iTF series, in the EV 35 lathe, gives the user a real comfort of work, and the MANUAL GUIDE overlay is a unique improvement.

Clamp – special device (OPTION, individual valuation)
The special pressure device is mounted on a special welded bracket bolted to the machine tool column.
For the chuck work, the special device quill is in the extreme upper position allowing the cross slide to enter in front of the device pressure plate. The device is equipped with a hydraulic quill with Morse 5 socket, through which it is possible to support the material. The amount of the clamping force is adjusted manually by means of the oil pressure in the quill cylinder by means of a reduction valve (OPTIONAL). The pressure value is controlled by one pressure transmitter – maximum pressure 3.5 MPa. The movement of the quill up and down is controlled by footswitches (impulse work – pressing the footswitch causes the tailstock movement, and its loosening – stopping) or in the automatic cycle by entering the appropriate M functions (non-impulse work – maximum extension or retraction of the quill).
