Techmax SDM-series Lathe - Description

Techmax SDM-series lathe is designed to provide outstanding performance and structural rigidity with large Φ100mm spindle bore

for turning and cutting a large workpiece

 

    Single piece cast iron bed

Heavily ribbed wide bed with induction hardened and precision ground bed ways for rigidity and low vibration. Its design authorizes chips fast removal. It is equipped with a bridge of which dismounting allows increase machining diameter.

 

 

         

    Headstock

The precision ground spindle is supported by high precision bearings suitable for both heavy and precision cutting. Spindle bore Φ105 mm 

is designed for large chucking capability.

 

 

Width of Bed: 550 mm

The slides are of an extremely rigid construction and the backlashes are adjusted by means of tapered keys. The slides are endowed with rubber wipers avoiding the guideways gripping. The carriage, fixed on the longitudinal slide, provides automatic feeds, rapid feeds and working feeds, as well as, manual feeds in two directions(longitudinal and cross).

 

 

 

Pivoting upper slide

The cross slide runs in a dove-tail guideway. Adjustment via pressure plate. Feed automatic or with handwheel. Both the longitudinal and cross slides can be clamped. A feed lever with safety lock prevents longitudinal and axial feed switch-through.

 

High Rigid Tailstock

The tailstock, made of top quality, has a rigid construction, vibration absorbing and can easily travel along the bed guideways. A lead screw, driven by hand wheel, allows axial movement of the quill on a 250 mm maximum travel. It can be set eccentrically with max. ±13 mm for cutting.

 

 

 

     Steady rest standard

The steady rest serves as a support for long shafts (length to diameter ratio of 3:1 or greater). The steady rest can be placed anywhere along the length of the workpiece.
