Double spindle CNC lathe 208 series

Turret Design Performance

The integrated positive Y-axis structure is highly rigid, heavy-duty, and has better performance than the interpolation Y-axis.

·Smoother and smoother plane contour processing

·Easier to process compound curved surfaces and contours

Compared with the "interpolation Y", the "positive Y" has obvious advantages in plane milling. The "positive Y" Y-axis movement is perpendicular to the X-axis and is a single-axis movement. The "interpolation Y" Y-axis movement is to interpolate a straight line through the simultaneous movement of the X-axis and the Y-axis. Compared with the "positive Y" for the flatness of the milling plane, the "positive Y" axis processing is obviously bright and smooth.

Direct Drive Synchronous Electric Spindle

High rigidity, high torque, higher efficiency, better finish, more precise indexing.

All major machine parts are made of cast iron HT300 with extremely strong shock absorption capacity.

Features of machine tools with direct-drive electric spindles

●Magnetic ring incremental encoder (sine and cosine) positioning accuracy: 20 arc seconds,

C-axis indexing accuracy: 40 arc seconds

●Fast start-stop response speed, saving machine tool time and effectively improving production capacity

●Small cutting load, energy saving and power saving, better protection of machine tools and extended service life

●Effectively eliminate spindle vibration, good balancing effect, good finish, and improve the surface finish of workpieces

(Advantages of turning instead of grinding, hard turning appearance, surface roughness Ra 0.2μm)

· The spindle motor is equipped with a cooling system to suppress the influence of thermal displacement and ensure that the spindle continues to work at a constant temperature.

(The nose end runout accuracy is within 0.002mm, ensuring more stable accuracy)

· Rear-mounted direct-drive synchronous spindle, more convenient installation and maintenance

· A2-5: 7016AC-front two rear two

· A2-6: front NN3020+100BAR10S, rear NN3018

A2-8: front NN3024+BT022B*2, rear NN3022

Heavy-Duty Cast Iron Base And Components

All castings are optimized using finite element analysis (FEA) to reduce distortion and lift-off shock absorption capacity. The castings of the major series of lathes are reinforced with ribs to enhance rigidity and thermal stability. Compact and symmetrical headstock and tailstock castings further enhance rigidity and ensure high positioning accuracy and repeatability.
