MTS 4.0 - Nullpunkt Spannsystem mit drahtlos digitaler Statusüberwachung

For highest process reliability

Integrated into the machine control system, MTS 4.0 provides comprehensive information and status displays on the condition of the MTS 4.0 chucks in real time. Electronic monitoring enables a completely new range of evaluation options: Proactive maintenance, accurate process analysis as well as extended monitoring options.

Only two pneumatic lines are required to control the MTS 4.0 base plate: Opening and reclamping (optional: cleaning air for automation).

Power is supplied autonomously via the integrated battery.

MTS 4.0 meets the increased safety standard according to ISO 13849 PLd- Cat 3.

EROWA Heavy PowerChuck
Large workpieces quickly positioned.
EROWA HPC consists of clamping modules that are positioned exactly where required by the table size of the machine and the optimum size of the pallet. Once installed and aligned on the machine, palletized workpieces can be positioned safely and quickly. Once the EROWA HPC are neatly centered and clamped, the pallets with workpieces are immovably able to withstand any loads caused by milling operations

Technical data:
Connections: Lateral and bottom: For opening and reclamping (pneumatic) and open control (electric).
Application: To accommodate multiple pallets.
Mounting: Mounting hole pattern for tables with T-slot spacing 100/200mm or directly on base plates.

Chucking system
EROWA AG
Chucking systems
Clamping system with central material feed-through and clamping on the outer ring for metal-cutting manufacturing.

The EROWA ProductionChuck 210 ingeniously combines proven EROWA accuracy with the flexible handling of a palletizing system demanded in modern parts manufacturing. The circumferential closing mechanism ensures a stable connection between the chuck and the pallet.The ø 81 mm hole allows material to be fed through centrally. This is a great advantage when machining workpieces on lathes and dividing heads.

The system is suitable for palletizing workpieces with a volume of up to 400 x 400 x 400 mm.


Technical data:
Pallet size: ø 210 mm
Repetition accuracy: less than 0.002 mm
Clamping force: 30'000 N
