TK69 floor boring and milling structural features

TK69 Series digital / CNC floor type boring and milling machine is an excellent performance, a wide range of technology, advanced equipment, high productivity can completely replace Planer and boring machine.

This series machines in large, heavy workpieces in one clamping, to complete a variety of milling, boring, drilling, plane surface machining.

This series machine has good rigidity, high precision, and versatility. In particular, a wide range of special accessories the (universal milling head, vertical milling head, elongation milling head, high-speed milling head, milling head swivel angle rear pillar, rotary table, etc. ), to further expand the scope of its application.

1, boring and milling head is one of the core components of the machine, the boring and milling head design has the following characteristics:

The spindle using 38CcMoAl nitriding treatment, therefore has sufficient hardness and good to maintain the accuracy.

Affect the accuracy of the spindle injector cooling to reduce heat to avoid spindle heat deformation caused by temperature rise of to avoid spindle high-speed rotating.

The square RAM taken to longitudinal sectional structure, in order to improve the longitudinal stiffness of the square RAM;

The overall inclusive spindle box structure, square RAM inclusive in the headstock, and further improve the overall stiffness of the square RAM, to favor machine tools for heavy cutting.

2, the transmission system

Machine tool spindle driving mechanical transmission and electrical governor, available 3--800r/min (optional 1000 rpm) inorganic speed range, in order to meet the needs of the cutting.

Feed drive is divided into four parts: The the front pillar transverse feed (X coordinate), vertical feed spindle box (Y coordinates), boring and axial feed (Z coordinate) and the RAM shaft like feed (W coordinates).

3, bearing

The spindle bearing is the key components of the spindle system bearing imports tailored.
