Our Quality
The quality system at Circ Manufacturing works from the top down. From approval of requirements, the design office 3D models are converted into full engineering drawings and data files needed for use in CNC software. Any changes or amendments can be applied directly at the top and all files and drawings are updated to ensure only the latest information is in use during production.
We use an Internal works order system. This comprises of a client approval process of the agreed work flow, process set up sheets and first article inspection reports. Repeat orders are documented and any specialised tooling required, can be stored ‘pre-set’ for a rapid turn around.
Our Jenoptik Hommel
We use cutting edge inspection equipment to verify all parameters. These range from micrometers, micro digital bore mics, slip / plug gauges and measuring Microscopes, to automated vision measuring systems from Jenoptik Hommel.
Our Jenoptik Hommel is regarded as the pinnacle for the automated shaft measurement of turned parts. This machine can cater for parts ranging from 0.20mm diameter to 30mm and a max length of 200mm. This range covers our entire work envelope.
A part is mounted in the machine between centers and then its green light camera scanning heads run up the entire part to produce an accurate form of the part on the screen. From here, the operator can build a test routine by applying a series of required measurements. From run out, coaxiality, length, diameter, threads, points of intersection, etc.
Once we have specified the tolerance limits of each parameter, the software will determine if the scanned component is within the tolerance limits.
Testing Output
It’s likely that the first part we subject to the test will show red flags where changes need to be made. We then work to create a part which fully conforms to the specified limits, with all green flags. This is then treated as the master component.
The test routine is saved and a detailed inspection report can be generated.
From here, we can now commence production of the turned parts and at pre-determined intervals, we can subject another part from the machine to the measuring system. With a single press of the measure button, a full scan of the test routine is performed in seconds.
We can also use this system to obtain statistical process control data and track how each feature of the part is behaving.
This technology doesn’t just save time for lengthy inspections; the level of accuracy obtained is crucial for us to determine feature relationships which would be almost impossible with older shadowgraph technology.
The machine is calibrated yearly to such a fine tolerance, that we can also internally calibrate our own gauges.
