As a result of the upgrade, the following changes were made:
1) The axis X is separated from the axes B and W
2) The speed of rotation of the spindle and the faceplate is regulated from 0 to nominal by using the GA700 frequency converter and an asynchronous motor of the ADRC series as the main electric drive.
3) The speed box of the spindle and faceplate is modernized and allows operation in 4 ranges M41, M42, M43, M44,
The change of ranges is made both in automatic and in manual modes.
4) Application of linear linear transducers
allows to provide positioning accuracy along linear axes with an accuracy of 0.01 mm, and table rotation with an accuracy of 5 “.
5) The main drive allows you to work in two modes:
a) Classic – the axis of rotation S;
b) axis with linear circular motion C;
6) CNC ShU – equipped with cooling fan with thermostat
7) SHU EP is equipped with a refrigeration unit.
8) The machine control panel is equipped with electronic indication of the load of the main electric drive and feed drives.
9) The CNC system allows you to display diagnostic, warning and alarm signals.
The radial faceplate caliper provides for the possibility of installing a measuring probe from HEIDENHAIN for the purpose of automated measurement of the geometrical dimensions of the installed product and transferring measurement data to the control program for processing the product. (An additional option. Installation according to your requirement is possible).
10) To comply with ISO-9002 safety standards, the installation of light-sound indication company “RITTAL”
11) Replaced guide lubrication system according to W, X, Y, B, Z coordinates. Instead of lubricators, there are three stations of pulse lubrication produced by “HAOLI”
12) The applied electric feeds and the main electric drive of the company “YASKAWA” can reduce electricity consumption by 30-40%.
