Three.  Construction feature of main component

3.1 Gearbox

Gear made of 40 Cr through High-frequency Quenching treatment, the Hardness reaches HRC40-45，gear grinder，Precision can reach level 6.Thereby reduce the vibration and noise of machine tools, improved efficiency and reliability.

3.2 Feeding system

Flexible coupling and ball screw directly connect to achieve horizontal and vertical turret feed and fast moving.

3.3 Lathe bed

Bed, as an overall structure, is made of high-strength, low-stress iron casting, adopt effective anti-vibration measures. Combination of bed and table base can improve the reliability of overall rigidity for machine tool substantially.

3.4 Cross beam

PTFE guide rail wear-resistant soft strip with a small friction coefficient was pasted on the contact surface of beam and column, greatly extended the life of the machine. The cross beam can move along the Z axis on the column guide rail. To go up and down through leading screw with a smooth transmission, small friction, low noise and high reliability advantages. Stainless steel telescopic shield was fixed on the horizontal guide rail of beam( X axis).  Beam grip adopt the leading screw clamping mechanism, safely and reliably.

3.5 Working table

The structure of whole working table is hot symmetrical, main gear shifting mechanism was fixed on the base of working table and the bed of lathe. Table radial centering by high-precision double-line short cylindrical roller bearing, to ensure the accuracy of rotation and improve the carrying capacity of the lathe. Table drive gear and all bearings are supplied with lubricant through specialized oil line by hydraulic system.

The working table is made of iron casting, it is a symmetrical geometry which ensure the working table move smoothly within rated speed.

3.6 Vertical tool post

The vertical tool post is made of beam slide base, gyration slide base, ram and other components.

Vertical tool post can move horizontally along the beam and ram move vertically, both X axis and Z axis are drive by Siemens or domestic Well-known Brand AC servo motor. The motor and ball screw are connected directed by one-way precise diaphragm flexible coupling.

Stable movement,  high transmission efficient, good precision retention. Guide ways of X axis and Z axis, ball screw, bearing adopt timed and rationed lubrication. Tool post vertical feeding motor(z axis) has brake, which can prevent power-off and tool-dropping of machine tool, ram adopts ball milling casting iron, single tool clamp is on be bottom end.

3.7 CNC system

CNC system uses Siemens 808D. X.Z axis digital controlling and two-axis linkage can be achieved.

3.8 Electric system

3.8.1 Electric component use Siemens or Schneider, ensure high reliability of machine tool.

3.8.2 Electric component has label, writing is clear and durable.

3.8.3 Wiring of whole machine tool is trim, wire size is complete, and writing is clear and durable.

3.8.4 Hydraulic system and automatic lubricating system components use superior-quality product with domestic permit or collaborative product, quality is reliable.
