Flat-bed CNC Lathe (AK-420, AK-520)
Features:
1. These series are economical and practical CNC lathes. With optimized structures,
unfailing performance, high quality, simple programming, and easy handling, they are
suitable for turning of complicated shaft, sleeve, and disk type workpieces such as
turning of internal and external cylindrical, conical, arc surfaces and various threads,
and even drilling, boring and reaming holes. And they are especially fit for turning of
diversified workpieces on small and medium batches.
2. They are of high versatility, high efficiency, low inferiority and good conformability.
So to be widely used in various trades, such as automobile industry, petroleum industry, military industry, and so on.
3. AK series accomplish stepless spindle speed changing by means of main motor frequency conversion and 4 shift hydraulic gear change.
4. AK…J series obtain 12 speeds all manually.
5. AK…P series spindle speed changing introduces main motor frequency conversion and 4 shift manual gear change.
