ANCA second-generation PremierPlus technology ensures consistent and efficient tool runout. With three times greater clamping force, tools are held more securely when grinding, increasing the consistency of tool geometry across a batch of tools. As the clamping force is increased it means more force is required to open the collet. This is enabled by a hydraulic pressure intensifier unit at the rear of the PremierPlus Adaptor used for this purpose.
Simon Richardson, ANCA product manager said: “The PremierPlus has been designed to control tool runout as it enables operators to radially adjust the collet via adjustment screws. As the clamp force is preset via the preload of the clamping mechanism inside the adapter, the operator does not need to remove the adapter from the machine when changing the collet.
“Simplifying the grinding process reduces set-up time and saves money. Adjusting the preload of the internal clamping mechanism ensures that larger-diameter tools can be rigidly held particularly when fluting tools at higher grinding forces.”
PremierPlus Collet Adaptor gives a cutting edge
Consistent and repeatable tool runout of ≤ 5 microns during production runs.
Rigid clamping improves quality of the finished tool.
Easy setup means less downtime.
Can be retrofitted for existing MX, TX and FX machines in the field with no need for modifications to the machine headstock.
Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
With nanometer resolution and control over the tool grinding path, the MicroX ULTRA delivers a high level of surface and edge quality. This achievement is made possible through intelligent algorithms that operate collaboratively and in synchrony.
As the only micro tool grinder with nanometer control, optimized mechanical layout and axes travel, integrated tool measurement and progressive automation, this six-axis grinder is the ideal solution for volume production of tools down to 0.03mm.
Flexibility is a key feature of the tap grinding process on the TapX. The specially designed machine and powerful ToolRoom software ensure a vast range of tap types and sizes can be designed and manufactured in one set-up. Combine this with the benefits of quick changeover time and it's not…
The FX7 ULTRA not only grinds tools faster than other machines, but also produces tools with both finer surface finishes and greater accuracy — which means superior tool performance and quality.
Utilizing ANCA’s machine platforms with a robot cell, blanket grinding offers flexibility across a range of tool sizes and applications. Blanket grinding allows for full automation of tools of similar geometries, by consolidating all tool grinding processes into one single machine. A batch of…
With the ANCA RFID (Radio Frequency Identification) regrinding solution, tools of various types and diameters and from different orders can be dynamically loaded, rather than having to sort them by diameter or customer as was previously necessary in mixed batches.
To increase the stiffness of the C-axis, the MX7 ULTRA combines developments to the nanometer or micro degree resolution in the linear and rotary axis, tuning parameters, several system enhancements, and major mechanical changes.
ANCA has designed a special dental drill loading kit including tailored RoboMate pallets for FX machines using a Fanuc 200iD robot loader. The pallet top allows a reduction of the insertion depth of the shank with an 8mm pocket depth, so that drills with only 10mm of available shank length can be…
The FX5, with the new 12kW spindle delivers increased productivity up to a diameter of 10mm. At 19kW, the new high-powered spindle option can enhance productivity further for tools up to 12mm and above. The high-powered spindle option on FX5 matches the grinding spindle fitted to the FX7 machine…
The 70% reduction in measurement time compared to Laser Plus is achieved through the new Analog measurement. The Analog measurement is a continuous edge scan instead of number of digital points along the cutting edge. This process also eliminates variations caused by machine standing idle, errors…
