Planner Bed Change Gear Heavy Duty Lathe Model Roll Master
 
Model AMI - Roller Master With Revolving Tailstock and Roller Steady
   

DESIGN & WORKMANSHIP : AMI lathe machines have been designed to cater need of sustained accuracy and superb finishing. AMI lathes are guaranteed for their original design, and are tested to the graded limits with specially imported precision tools.

BED :
The bed being the foundation of the lathes is carefully designed and is of high grade cast iron. It has cross-ribs to support its walls and three inverted 'VEES' assembled with a removable gap for large swing.

HEAD STOCK :
The head-stock is of top quality castings providing support to the spindle bearings. The bearings are of the following three types:

(a) Parallel Brass with thrust Bearing, (b) Conical Brass, (c) Taper Roller Bearing. The inain spindle is the best steel with a finish to give accurate results. Head Stock gears are of "Clutch system" of high production in small machines & "Kirloskar system" in large machines.

SADDLE : The 'V ways running on the bed and the slides are most accurately hand scrapped and aligned accurately with the bed and the headstock. The saddle is fitted with 'Hand' and 'Automatic' transfers along the bed with steel rack and Pinion.
It is assembled with cross and upper slide graduated to give desired angles.

TOOL POST : The Toll-Post is made out of one piece steel block and can hold four different tolls at a time and can be swivelled to any desired angle.

APRON : The apron gives movement to the saddle for screw cutting sliding and surfacing by means of enclosed gears and half nut. All gears are of steel and are well tempered.

TAIL STOCK : The tailstock is designed to give maximum strength bolt operation. It has long bearing within the barrel and ensures true alignment.

THREE SPEED GEAR BOX : The Three speed gear box is provided with the lathe to obtain coarse, medium and fine cutting ranges, both long and cross on the feed bar through gears. The lead screw with accurate threads is to be used only for thread cutting & can be engaged or disengaged with a handle provided on the gear box while the other handle is for obtaining the desired three speeds.
