4. Introduction of the machine

(1) CNC Floor type Boring machine is a general-purpose machine which is designed and manufactured with new technology such as modern mechanical, electrical and hydraulic technologies.

(2) This machine not only has extendable boring spindle to carry out the machining by common floor-type boring machines but also has extendable square ram which is equipped with both milling and boring spindle.

(3) It adopts a lot of advanced automatic accuracy compensation technologies, such as pre-pressed, on play, high accuracy ball screw drive in axes X,Y,Z,W, multi-point, closed multi-point hydrostatic guideways on linear guideways with dynamic and static friction coefficient of no crawling at low speed.

(4) The CNC system of the machine adopts the German Siemens 840D CNC system, realizing the simultaneous motion of any 4 axes, This machine can complete milling, boring, drilling, tapping and curve surface and curve line machining in five axes (such as propeller blade) through one set-up.

(5) It is the mechanical-electric integral product of high automatization and hi-tech with high accuracy and excellent rigidity. If equipped with vertical, universal, extended milling heads and CNC rotary table, it can be applied on wider range, especially on large, heavy and super heavy complicated parts.

(6) It is the key equipment for national important equipment and industry, which can replace the imports. It has reached the international advanced level but the price is 3 times lower than the same product abroad. It has strong competitive ability in the market and can be widely used in military industry, nuclear energy, metallurgical, shipbuilding, aviation, traffic industry and national important machinery industry enterprise.

6. Technical Innovation of the machine:

1. The main driver of the machine adopts advanced second gearshift and stepless electric variable speed gearing, which can realize the stepless variable speed gearing in wide range. The main driver motor adopts imported spindle motor and the starting torque is great. It has the orientation ability for the main spindle.

2. The slide bed, ram and main spindle adopt closed multi-point hydrostatic guideways with low dynamic and static friction coefficient and keep no crawling at low speed in feed process.

3. The feed drive components in axes X,Y,Z,W adopt the pre-loaded backlash free high accuracy ball screw.

4. The linear movement of the column rams and headstock adopts floating clamp installation. The clamp speed is fast and reliable, which keeps the thickness of the oil film out of effect.

5. The tool clamp of the main spindle adopts disk spring-group clamp and hydraulic pressure loosening way. It is safe, stable and fast.

6. The guard of lathe bed and column guideway adopts stainless steel guard produced by the domestic specific factory.

7. The spindle bearing adopts imported spindle bearing with high precision to maintain the accuracy of the spindle.

8. The machine control system adopts the FAGOR 8055(optional: Siemens 840D or FNUC) CNC system and the feed motor adopts the FAGOR digital AC servo motor. It can realize 4-axis control and any 4-axis simultaneous motion.

9. It adopts the adjustable spiral capillary damping throttle, which occupies small room and is adjusted easily.

10. The hydraulic system of the machine adopts the closed centralized feeding and returning system.
