COLLET CHUCK EXPANSION SYSTEM

The new collet-chuck expansion system type SME, designed under the philosophy of FORMULA SYSTEM (on mandrel basis we build the proper clamping system for each kind of production to perform) that allows a clamping solution powerful and modular.

Main characteristic is the utilization of a “PIN” (push system), that guarantees the same level of perfomance of tie rod (pull system) and is slightly bigger in order to be less subject to curves so it can sustain each kind of radial manufacturing process.


ADVANTAGES


• Minimum clearance
• Piece clamping with stationary collet radial clamping without pull-back effect
• Does not mark the surface of the piece
• Fewer machine downtimes
• High repeatability accuracy
• Machining tolerance lower than DIN tables
• Range of machining: +0.5mm/ – 0.5 mm
• Clamping of raw pieces (rolled, forged, castings)

SME – Clamping collets


•UNILOCK_PINZA_SERRAGGIO_ESPANSIONE_SME
SME clamping collets are made up from metal inserts, units of vulcanised rubber.
This allows the collet to close radially in a perfect manner, blocking the piece along the entire length of the hole and eliminates the intrusion of shavings to pass inside the spindle.
Unilock clamping collet type SME work with conical clamping. This allow to get a great precision, a big clamping power with a significant reduction of the vibration.
STATIONARY COLLET-CHUCK SYSTEM WITH RADIAL CLAMPING WITHOUT AXIAL MOVEMENT


ADVANTAGES


• UNILOCK SME COLLET close with tapered coupling. This features allows a bar clamping over the entire lenght of the collet hole.
• Great clamping strenght
• Clamping with stationary collet• Great clamping strenght
• Clamping with stationary collet
• Excellent elasticity
• Reduction of vibrations
• Less tool wear
• No wear on the collet
• Does not mark the surface of the pieces
• Quick collet change
• Fewer machine downtimes

SPECIAL APPLICATIONS


Unilock can also plan and produce in “co-design”. Taking this approach, our technical office works with customer to assist in the design process, suggest modifications and improve the product for optimal results.Unilock_Expander_app-speciali Fig. 1 – Ideal for Aluminium foundry process
