The original CNC system of the machine tool cannot be started normally; the ball screw, screw bearing and linear guide of the linear axis are worn; heat is generated during the rotation of the spindle; the sensor switch of the tool magazine is damaged; the flatness of the worktable is out of tolerance; the pipelines of lubrication, cooling and pneumatic systems Ageing;

Need to replace the supporting CNC system, restore the accuracy of the machine tool, replace the aging parts.

 

 

 

 

solution   

 

 

Adopt GSK25i numerical control system, supporting servo motor and servo drive for transformation;

Replace the ball screw, screw bearing and linear guide of the feed shaft;

Overhaul the spindle, replace the spindle bearing to ensure the spindle accuracy and spindle speed; drive the spindle through the servo spindle motor to realize the spindle high-speed processing;

Overhaul the tool magazine, replace the damaged inductive proximity switch, accept the feedback signal; reliable tool selection, accurate positioning, ensure the normal tool change of each station; re-write T map, make the cutter head can be reversed, change the tool nearby, save time, And replace the damaged knife holder;

Re-scraping the worktable: through our factory with many years of experience in scraping research, the worktable is re-scraped to ensure the flatness of the worktable, thereby ensuring the accuracy of the processed workpiece;

Replace the grating ruler, the access signal is TTL; adopt HEIDENHAIN precision grating ruler to realize the full closed-loop control of each linear axis;

Overhaul hydraulic, lubrication, cooling, pneumatic systems and replace damaged parts;

Add workpiece probe (Renishaw);

Redesign the electrical control schematic diagram of the machine tool, replace the electrical control and electrical components and rewire.

 

Application effect

 

 

Restore the precision of the machine tool and all functions used, and run stably;

Meet customer requirements for parts processing.
