Leistritz Polymat hydraulic keyseting machine

Hydraulíc keyseating machíne POLYMAT-CNC

Use and Setup structure
POLYMAT CNC is the result of a customers like systematic development for an economical production of keyways, spline profiles, internal gearings, tangent keyways, involute
and polygonal profíles as well as of internal profiles in all imaginable variants.
Unít Constructíon System
All construction units easily accessible.
Compact Constructíon with casting machine stand and base for high rigidity.
Absolutely safe and servíce-free lubrícation system.
Slíde guidíngs with hardened, ground and superfinish worked double piston rods.
Floatíng tool suspensíon
No static load on the guidings.
Portable control panel
with central arrangement of all control elements.
Programming by dírect gívíng-ín by hand.
Rapíd traverse for the cutter in feeding direction and automatic rapid return traverse.
40 m/mín.
Cuttíng speed stepless adjustable also during the drawing operation up to max.
22 m/mín.
Automatíc switch-off when key depth is reached switchingoff accuracy ± 0.005 mm.
Automatíc regulatíon of tensíle load for the protection of the tools.
Double cycle hydraulic to avoid heating of oil during continuous working.

Operatíon
A cutter serves for the cutting and produces the profile in plies running in
vertical direction with continuous stroke movements alongside the boring in connection with a horizontal feed. The feeding adjustment is done after each stroke by the movement of feed bar which is moved step by step between cutter guide bar and cutter bar with the cutter according to the amount of thíckness of the cuttíng.
Before the upstroke the cutter is withdrawn automatically. The slides for the stroke- and feeding movement as well as the withdraw cylinder are hydraulically controlled.

Constructíon
Elements
CNC-Control:
3-axles CNC for stroke, delivery and dividing mechanism.
Digital required and actual valud indication. Decimal keyboard with comma and mínus sígns. 8 functíon key buttons.
6 luminous diodes for indicating the operating condition.
Automatic computation of the tangential intersection point using a subprogramme.
