Configuration Introduction

High Processing Performance

FANUC 0i-TF PLUS system has powerful high-efficiency processing technology and intelligent servo control technology; high-efficiency processing technology shortens the sequential processing time of external signals according to the acceleration and deceleration of the action state and maximizes the use of servo capabilities, thereby reducing the processing program cycle time; intelligent servo control refers to a servo control function group that can self-optimize and adjust in real time as the machine tool conditions such as load and temperature change, achieving high-speed and high-precision processing.
High Ease Of Use

FANUC 0i-TF PLUS system has a large-capacity program memory, CF card can be used as program memory, USB program can be run with one click, CNC-QSSR function helps machine tools quickly and easily import robots, and the optional system IHMI function provides comprehensive support for work on the processing site, and provides tool information integrated management, processing time prediction, interactive dialogue programming, mechanical collision avoidance, processing data collection, maintenance management and other functions required for each process in the process of "planning", "processing" and "improvement".
High Operation Rate

The IOlinki and FSSB of FANUC Oi-TF PLUS have rich fault detection functions, which can determine the power failure of the I/O module or servo amplifier and the location of the communication cable disconnection. In addition, I/Olinki can detect the output short circuit of each DO point; in addition, the fault diagnosis function can obtain various diagnostic information on the CNC screen that helps to judge the system status when the alarm occurs, helping users to quickly repair the problem area
THK Ball Screw

· C3 grade, using high-precision ball screw, with nut pre-loading and screw pre-tensioning treatment to pre-eliminate backlash and temperature rise elongation, showing excellent positioning and repeatability accuracy.
· Servo motor direct drive to reduce backlash error.
THK Roller Linear Guide

· P grade ultra-high rigidity SRG precision grade, linear guide zero clearance, arc cutting, bevel cutting, surface texture is relatively uniform. Suitable for high-speed operation, greatly reducing the driving horsepower required for machine tools.
· Rolling instead of sliding, small friction loss, sensitive response, high positioning accuracy. It can bear the load in the moving direction at the same time, and the track contact surface is still in multi-point contact during the load, and the cutting rigidity will not be reduced.
· Easy to assemble, strong interchangeability, and simple lubrication structure; the wear amount is very small and the service life is long.
SKF Bearing/Oiling Machine

· Automatic lubricator meets the needs of various applications, suitable for various working conditions, reliable products, flexible use.
· Meet the needs of bearing lubrication in high temperature, strong vibration and dangerous environment.
· Each lubrication point uses a volumetric proportional distributor to control the lubrication amount, and the machine can be controlled by PLC to accurately supply oil.
