iJaw
After Market Solution

With the iJaw Mobile App you connect your jaws to the system, create job projects, have a real-time view of the clamping forces and analyze the productivity and quality of your production batch.

The graphic shows the clamping force data of the machining of a turned part. The curves of roughing (1), finishing (4), drilling (6) and milling (10) have certain characteristics. The increase in amplitude indicates increasing effective forces and the decrease in the curve indicates higher speeds.

The visualization of effective forces on the tool and workpiece during the machining process opens up completely new possibilities for optimizing the machining process. Now machine operators and process optimizers can rely on measured data when they want to speed up machining processes.

HIGH TIME SAVINGS IN SERIES PRODUCTION
Knowing the right effective forces means approaching the workpiece with the maximum possible machining forces. Feed and speed are optimally adjusted so that the machining time for a workpiece can be dramatically reduced. Not only in series production does this mean more throughput and lower part costs

Why is the machine stopped? When does it do chip removal? How productive is it?
These are all questions that you can also answer with the iJaw. A simple analysis shows you uptime and downtime. This allows you to start further analyses at shop floor level and optimization. Especially in times of rising energy costs, optimization of production processes is a must. The iJaw makes potentials transparent!

The iJaw measures the clamping force between the clamping jaw and workpiece in real-time. The clamping force curve is like the fingerprint of the production step. Each component has its own signature. Significant deviations from part to part in series production indicate malfunctions and faulty production. Parts with a deviating fingerprint can be identified quickly. This speeds up quality assurance and reduces costs.

• Detection of rejects
• Sorting out before the next processing step saves follow-up costs

If you machine thin-walled components, you may be familiar with the problem of deformation when the clamping force is too high. The iJaw helps you to clamp workpieces with exactly the required force and thus prevent deformation of the parts – and thus scrap.

• Clamping with exactly the right force
• No deformation of thin-walled components

With the iJaw, you can see the clamping forces applied during the machining process in real-time. By knowing the minimum and maximum clamping forces, you can set up alarms when the applied clamping force is exceeded or not reached. This makes machining safer for people and materials, because you protect your employees and avoid costly accidents.

Fulfillment of the obligation to provide evidence

With the iJaw, clamping forces can be measured and archived and thus documented. At any time after machining, the manufacturing process can be traced.

Carrying out analyses

The clamping force data is stored and thus documents the machining process. The production of critical components can thus also be analyzed retrospectively. This is, for example, for damage analysis or to investigate weak points in complex and lengthy manufacturing processes.

A set of jaws consists of three iJaw jaws. Usually, one jaw with sensors is sufficient for measuring and wireless data transmission. The other jaws have no sensors. They are mechanically identical in construction and have corresponding balancing masses for perfect concentricity even at high speeds.
All jaws have a console that can be individually equipped with exchangeable clamping inserts and thus adapted to the clamping task. The transmission unit is sealed with a special plastic to protect against abrasive and hot chips.

1. Console jaw, single-stage
2. Clamping insert single-stage
3. Face contact bolts
4. Console jaw, two-stage
5. Clamping insert, two-stage
6. Console jaw, through hole
7. Clamping insert, through-hole

The iJaw system consists of a set of jaws, one of which contains the sensor. The antenna, cable and the iJaw Connect gateway ensure data processing and transmission. And the optional tablet is used to visualize the data through the iJaw Mobile App.
