Techmax CB-series Lathe - Description

This is a general presentation for the entire CB-series. Models may have some minor differences.

 

Single piece cast iron bed

Double casted bridge structure is your guarantee for stability

The bed, made of high quality Meehanite cast iron, provides toughness and vibration strength. Its design authorizes chips fast removal. It is equipped with a bridge of which dismounting allows increase machining diameter.

 

 

 

Headstock

The headstock is made of high quality cast iron, heavily ribbed, is designed to absorb vibration even in hardest machining cycles.
The rigid, large main spindle runs in high-precision adjustable taper roller bearings. The gearbox offers a wide range of cutting speed plenty of torque allowing machining of various materials. It is designed to have a smooth running with low vibrations and with a closed shape.

 

Width Of Bed

Single piece casting bed

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. The upper slide with dove-tail guideway can be pivoted 360°. 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 120 mm maximum travel. It can be set eccentrically with max. ±13 mm for cutting.

 

 

 

Central lubrication system for all slides

A centralized lubrication installation provides the gear box and feedbox lubrication.The carriage and the slides are lubricated from a pump fixed inside the carriage.

 


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.
