| |
| |
Models Available : |
| |
|
|
|
Standard Model with Servo Motor driven Longitudinal slide and Mechanical gear box with fixed spindle
speed ratio of 1 : 2 . Spindle speeds variable through variable frequency drive. Suitable for even numbered polygons
at the end of the component. |
|
TPT - 2S : |
|
Advanced model with Servo Motors for the Longitudinal and Cross slides, mechanical gear box with fixed
spindle speed ratio of 1 :2, spindle speeds variable through variable frequency drive. Data input through MMI on
operating panel. Suitable for even numbered polygons, can generate Chamfers, Tapers, Radius at the ends and in
the middle of the component. |
|
TPT - 4S : |
|
Versatile Model with Servo Motors for the Longitudinal and Cross slides, spindles with electronic gear box. Data input through MMI on operating panel. Suitable for Polygons, Ratchets, Slots and Splines, can generate
Chamfers, Tapers, Radius at the ends and in the middle of the component with no limitation on the numbers of sides
of the polygons. |

Variety of Components at a Glance : |
| |
|
| |
|
|
|
* Polygon turning process has the shortest cutting time compared to conventional machining.
|
* The process is well suited for mass production & batch production.
|
* The process uses standard inexpensive turning insertes instead of milling cutters for machining
|
polygons. |
* The polygons machined are concentric to the job axis since the job also rotates along with tools.
|
* A variety of polygons & face teeth can be machined.
|
* Simple & fast change over of setting to another polygon.
|
* Has the lowest cost per piece compared to any other operation. |
|
Polygon turning is a unique generation process like gear hobbing. The desired polygonal surfaces are generated using inexpensive single point turning tools. Because of this, the surface texture is uniform & attractive & the surface finish is very good. |
