APPLICATION
TK69B/TH69B series CNC floor type milling & boring machine (center)adopt finite element optimum design, with functions of boring, drilling, tapping, groove milling, plane milling, etc. Equipped with function attachments such as high precision CNC rotary table, right angle milling head, the machine can realize 5 surfaces machining. It is the ideal equipment for processing steam turbine, generator and heavy duty machine tools in industries of metallurgy, power a and electricity, etc.
The main performance characteristics:
- Spindle bearing adopts import super precision angle contact ball bearing of famous brand; oil gas lubrication is adopted to efficiently control temperature rise of bearing and assure the stability of spindle during rotation at high speed;
- X, Y, Z and W axis adopt pump per pocket type closed hydrostatic guideway with constant flow;·X axis adopts double rack and pinion clearance elimination transmission;
- Z and W axis adopt preloaded ballscrew transmission;
- Y axis adopts double- axis multiple-motor simultaneous elevation transmission;
- Headstock balance compensation adopts double axis simultaneous balance compensation;
- Attachment bracket and attachment magazine as option for manual or auto change of attachments· Auto diagnosis function for convenient operation.
- It can be equipped with ATC to realize high efficiency machining.
