CNC Swiss Type Automatic Lathe

Description

All needs of the times are included and integrated into one machine. Multi-functional & low cost / performance ratio.

B-axis swiveling tool spindle processes with C-axis, increasing the ability to cut the accurate angles. The B-axis feature makes this machine into multifunction equipment can turning or milling any angle.

Best choice for batch or mass production of various complicated parts.

Modular tooling
- Free arrangement of different tool spindles, ID tool holders and OD turning tool holders according to tooling requirements of the parts to be produced.
With separate back tool post and cross traveling of back spindle, exactly simultaneous machining at main spindle side(S1) and back spindle side(S2) can be achieved without need to wait with each other, reducing cycle time much.
With Y-axis for back tool post
- 4 live tools(T35~38) and 4 fixed tools(T31~34)
- Back cross tool spindle(as the picture shown below ) : Available for back slitting、cross drilling、tapping or milling ,depending upon cutting tool in use . Total 2 back cross tool spindles can be mounted with one tool position between.
- Back tool spindle: Available for back milling、 off-center drilling、tapping, etc.
- Cartridge type tool spindle design for T31~34 , available for interchange with other different tool spindle or adaptor for fixed tool , more choices for tooling layout design
Direct motor-drive rotary guide bushing, available for high-speed and accurate machining
- Max. speed: 12,000 min-1
- Max. machining length : 210 mm Geometry accuracy、dimension accuracy and surface roughness are much improved, with less noise even at high speed.
Guide bushing type or guide bushing- less type is selectable according to length of the parts to be produced
- Guide bushing-less type does not require ground bar stocks, suitable for cold drawn bar machining also, reducing the remaining bar length.
4-spindle cross tool attachment can be mounted, available for Y-axis complex tooling, such as cross drilling, tapping, up-down milling, etc.
Additional face deep hole drilling post is attached beside the back spindle. Max. drilling depth can be up to 100 mm.
- Single-face or double-face drill collet holder can be mounted at ∮22- bore 5-position fixed ID tool post , available for face or both face /back ID working
Direct C-axis indexing
- When spindle indexing is done from spindle rotating state, it stops at indexed position directly, without need to return to reference point, reducing spindle indexing time.
High rigid machine bed
- Machine bed design was supported by FEM(Finite element method) analysis to produce high-rigidity machine, assuring high-speed, high-accuracy machining.
Work catcher
- Conveying the work discharged from back spindle through the chute to work conveyor, then work container
