FTNC-20G FTNC-20GT Small Type Precision CNC Lathe require small installing space and low cost, and are designed to deal with the precision machining of small diameter. With maintenance-free servo motors adopted, FTNC-20G FTNC-20GT is characterized by small size, high feeding accuracy, easy operation and maintenance, smooth escape of chips, etc. CS function can be set to realize precision machining of curved surface.
The machining precision is within 0.2μm: the spindle adopts super precise radial ball bearing making it possible to achieve high speed and high precision processing within 0.2μm for both roundness and surface precision.
Features
Dovetail sliding guide rail:
Guide rail adopts high quality cast iron with quenching, grinding and scraping treatment, which prolongs the precision retaining period of the guide rail surface and keeps stable precision for a long time.
Proper gang tool structure:
This machine is equipped with the proper gang tool structure and sufficient tool installation space. Precise machine tools for drilling, tapping, boring, milling and thread cutting can be installed in the tool post.
Space saving: can be installed in small space of 1100x1050mm.
Powerful AC servo motor:
For the spindle drive, we have provided infinitely variable speed by means of a 3.7kW FANUC AC servo motor.
In addition, we have adopted a maintenance-free
Digital AC servo motor for each spindle feed.
High precision feed: each guide surface has been dovetailed with sufficient length and equipped with automatic
lubrication system ensuring high precision feed for long period of time.
Easy maintenance: wide openings have been assured for all doors and easy to use devices, such as control
buttons, to facilitate exchange and maintenance.
Selection of diverse automatic fixture unclamping & clamping device:
The shift fork type clamping mechanism and collet chuck clamping mode(standard)
The pneumatic rotary cylinder and precision pneumatic chuck (optional)Processing precision within 0.2um Through the adoption of super precise angular main bearing for the main shaft bearing it has been possible to achieve high speed high precision processing within 0.2um for both roundness surface precision.
