3. General instruction:

(1)CNC fixed beam gantry boring-milling machine is a general-purpose machine which is designed and manufactured with new technology such modern mechanical, electrical and hydraulic technologies.

(2)Its CNC system adopts foreign advanced CNC system which can realize any three-axis linkage.

(3)The machine with large application scope and extensive function is a general-purpose metallic cutting machine with higher machining capacity.

 (4)The accessories such as right-angle milling head, universal milling head etc. can be installed at the front end of square ram. So the machines not only carry out the large dia. And large plane surface cutting, but also carry out the machining of internal cavity, side face of internal cavity, internal cavity hole and large end face stop port of many workpieces.

(5)So the machine has good functions of milling, boring, drilling. It can complete the multi-face machining in clamping for once if it is used by equipping with the rotary table.

(6)The special tool arbor shall be assembled with the CNC facing head. It can do the machining of the taper workpieces with large dia. range and large angle range.

4. Whole structure of the machine

 (1) The structure of the machine is fixed-beam gantry milling and boring machine structure and it is mainly composed of table, bed, gantry frame, ram-type boring-milling head, slide carriage, hydraulic system, lubrication system, cooling system, CNC system, electrical control device, button station etc.

(2) Mainly large parts of the machine

  Main spindle of the machine is accurately made of 38CrMoAl high-intensity, nitridize qualified alloy steel. The important large parts such as ram, sliding carriage, table, bed (it is jointed by multiple beds), left and right columns, cross beam, etc. all accurately made of HT300 cast iron with high intensity and low stress. The secondary aging treatment is done to the large parts before finish machining.

(3) Ram-type boring and milling head

The main spindle parts and components of ram-type milling and boring head is made in Taiwan. The main spindle bearing adopts the product of NSK, Japan which has characteristics such as high speed, high accuracy, long life, and so on.

(4) Guideway of the machine

  Guideway of X, Y and Z axes all adopt hydrostatic guideways.

(5)Hydraulic system

The hydraulic pressure station set up independently, and the hydraulic parts and components are made in Taiwan.

(6) CNC system of the machine

  CNC system of the machine adopts Fagor 8055 CNC system (optional: Siemens 840D or FANUC-OI MC)
