The Advantages of New Siemens 808 Advance System are as below:- The benefits are as per below:- 1. It is close loop system so positioning accuracy of axis is far better. 2. It has Auto servo tuning (AST) facility so that load can be tuned with servo motor for better performance with torque. 3. It has Direct servo control (DSC) by Drive Bus communication so that drives can perform better with controller commands. 4. It has friction compensation facility. 5. Servo motors available up to 40Nm whereas in 808D it was only 4,7,10Nm only.(e.g. for Z-axis we used 15Nm 6. Absolute encoder available with Servo motor so that referencing is not required (like 828D) 7. It has Ethernet communication port so that PLC and Data Upload/Download is much faster. 8. It has Ethernet Interface so that it can be monitored remotely (like 828D) for a. Transfer of Part program, user cycles, Machine data, R-parameter, PLC data, HMI data etc.. b. PLC Logic can be monitored c. PLC upload/download d. Part program send/receive e. Execute part program f. Screen shots can be taken. This machine is recontrol or recertification with SIEMENS 808 Advance System Exactly as per Pfauter Standards.
All recontrolled and recertified machines are fully cleaned.
All moving slides, spindles and parts handling systems are inspected for problems.
Any gibs or adjustable backlash systems are adjusted to the best possible settings.
All hydraulic, coolant, lubrication and pneumatic systems are checked for proper functionality and leaks.
All filters are replaced. All worn hoses, broken cables, connectors, buttons, lamps and wires are replaced.
All guarding is installed and checked.
All machine cycles are tested. Parts are cut to verify the machine capability.
Charts from the test cutting are documented for your viewing.
