Workholding Clamps and Fixturing Solutions
Supporting modern machining with automated clamping solutions
Automated clamping is a key enabler for modern machining environments where productivity, repeatability, and unattended operation are essential. Automating the clamping process can shorten setup and changeover times and improve consistency, especially when integrated thoughtfully into CNC, pallet, or robotic systems. With proper design, automated clamping contributes to more predictable fixturing and helps reduce operator-dependent downtime in repeat production.
OK-VISE low-profile clamps are well suited for automation thanks to their simple, robust operating principle. Because the clamp is actuated by pulling the center bolt/wedge, the same motion can be produced by common actuators used in automation.
Our solutions allow clamping to be automated using electric, hydraulic, pneumatic, or mechanical actuation—depending on the needs of the application.
ELVA – Electrical Clamping System
ELVA – enabling maximum flexibility in automation.
ELVA is OK-VISE’s electric clamping solution developed for automated machining environments where simplicity, reliability, and controlled clamping are essential.
Unlike systems that rely on continuous pressure, ELVA uses an electric motor only to actuate the clamp. Once the clamp is tightened, the workpiece is held mechanically in position without ongoing power consumption. This makes ELVA inherently energy-efficient and operationally reliable.
The design delivers benefits like
- Easy plug and play automation
- Radically shorter production ramp-up times than with traditional clamping automation
- Need for special expertise is avoided
- Safe and clean energy supply with economical coupling and decoupling
Hydraulic clamping solutions
For applications requiring higher clamping forces or centralized control, OK-VISE offers hydraulic actuators that can be used to automate low-profile clamps.
Hydraulic automation is well suited for:
- Multi-clamp fixtures
- Palletized machining
- High cutting forces or heavy workpieces
By connecting multiple clamps to a single hydraulic circuit, all clamps can be actuated simultaneously, ensuring consistent clamping across the entire fixture.
OK-VISE hydraulic clamping solutions
- are based on the world-renowned wedge clamp
- has a wedge design that hinders compression of hydraulic oil and prevents vibration
- uses a HA-Series actuator designed for 350 bar pressure, hence a compact size
How does it operate?
Our hydraulic actuators
You can find different models of hydraulic actuators (=cylinders) from OK-VISE
In addition, these sets include all the adapter bolts and fittings required to automatize B- or D-series clamps.
Depending on the clamp size, a 8 mm or 12 mm bolt goes through the clamp and fixture plate to the cylinder ‘s piston. The base cylinder is bolted on to a fixture plate.
The cylinders in the sets are single-acting, enabling the simplest possible actuation of OK-VISE clamps
Pneumatic and mechanical automation options
In addition to electric and hydraulic solutions, OK-VISE clamps can also be automated using:
- Pneumatic cylinders, where compressed air is readily available and a simple on/off actuation is preferred.
- Robot-driven screwdrivers, which tighten and release clamps mechanically as part of an automated handling cycle
These approaches offer flexibility when integrating clamping into existing automation systems or robotic workflows.
