In the Australian wood processing industry there is significant demand for compression routers (tools with opposing cutting flutes) also known as compound shear or up-down cutters.
Leitz Australia needed to find a suitable tool and cutter grinding machine that met their requirements.
“Leitz identified that to meet market demands, the machine had to be highly productive and satisfy the exacting tolerances set by Leitz,” said Charles Joel, national manager of production/service at Leitz Australia. “Local customer service and applications support was another important aspect.”
After an extensive review of several tool and cutter grinding machines, Leitz concluded the ANCA was the best machine on the market to meet their needs.
In 2016 the FX7 Linear CNC grinding machine was installed and was configured with the high capacity Fanuc robot loader, ANCA Motions cylindrical LinX linear motor (patented by ANCA), full size touchscreen and a handheld pendant for simplified setups.
“After three days of basic operator training, the machine was operating at full production capacity,” said Joel. “Since the FX7 was installed it has produced almost 10,000 tools so we have been thrilled with the machine uptime.
“The flexible software and time savings was another important feature. Using the 3DCimulation software on our offline PC means we can verify the next tool type to be produced, while the machine is in use grinding tools.”
“The 3DCim software can check and calculate all aspects of the tool, including dimensions, geometry, profiles, etc. which is critical when measuring items such as core diameter prior to grinding to avoid any production problems. The software saves time on tool design, reduces grinding setup time and ensures accurate tools are ground first time at the start of grinding a batch of tools, resulting in actual cost savings”.
“One of the advantages of the FX7 is the reduction in delivery times. The machine has a robot loader for fast production of special tools in large quantities that can now be delivered within days. Furthermore, it has a capacity to manufacture up to 320 pieces for Ø8mm routers (maximum of 840 pieces for Ø3mm) and the loader has four times the capacity of the machine we previously used to produce compression routers. “
“Not all production runs need to be in large quantities. The machine can do multiple tool types of the same diameter size in the one pallet. Small batches of 5-10 tools of 30 different tool types could be done in the one production setup”.
ANCA’s Machine Notification Software (MNS) has a feature to remind customers when maintenance tasks are due. This results in continual productivity and the reduction of machine downtime.
Despite the FX Linear machine’s large working envelope, it maintains a relatively small footprint. Every item of the FX Linear machine, from the positioning of the grinding wheel on the C-axis centreline (to reduce thermal influence), to the Fanuc robot which loads both tools and grinding wheels (up to 6 wheel packs), have been aimed at enhancing accuracy, increasing productivity and making operator’s tasks significantly easier.
To save energy, the FX7 comes with an idle shut off feature that can be programed to shut the machine down completely when it is idle for a set period of time. This allows the machine to start a tool production run on Friday and when finished over the weekend, it will automatically shut down the machine, saving in power consumption.
