Grinding process increases twist drill
output
Using up to six grinding wheels and integrated wheel dressing in one rigid machine tool avoids multiple handling between grinding processes when producing high speed steel drills.
ANCA together with Norton Abrasives has developed a grinding technology process 'FASTgrind' for high speed steel (HSS) drill manufacturing The method provides comparative results in terms of output volume with those of traditional manufacturing methods

The purpose of this paper is to attempt to give a better understanding of CNC tool grinding, the advantages of CNC ground tools, case histories of actual usage its benefits and its justification.
Compact tool and cutter grinder produces miracles
Launched at Grind Tec, in Germany, a compact CNC tool grinder has the power, strength and working envelope usually attributed to a much larger machine.
The advantage is relatively low capital investment and unbeatable flexibility.
FASTgrind process - traditionally, HSS drills are made on several machines, using either aluminium-oxide or CBN grinding wheels.
The logistical flow from blank to a finished drill involves manual handling of semi-finished products and difficult and lengthy set-ups when changing drill batches.

What you see is the tool that you grind
Said to be one of the first of its kind in the tool and cutter industry, software models, tests and optimises the tool and cutter grinding process before the tools are ground on a CNC machine.
In addition, the capital investment for several special purpose machines is very high.
The ANCA-Norton solution meets key criterias of HSS drill manufacturing such as - rigid machine, high performance grinding spindle, in-process dressing, grinding wheels with high cutting speeds, optional coolant delivery and automation.
ANCA TX7+ - rigidity is essential in successful high-speed fluting and is made possible through the advanced design.
The result of using Unigraphics, 3D CAD software and new mechanical and kinematics concept has been developed.
Together with the polymer concrete base, guarantees extremely high rigidity and stiffness.
Direct driven spindles ensure highest possible transmission of power as well as smooth resulting surface finish on a ground tool.
During production, the automatic wheel changer allows use of up to six wheels in a single set up.
Coolant pipes are changes automatically to suit particular wheel configuration.
The coolant delivery unit eliminates the problem of burning tools.
Integrated wheel dressing capability is essential when attempting extensive production.
ANCA's direct driven headstock makes it possible to drive the dresser roll with up to 3,000 rev/min.
An automatic loading system with up to 220 tools per pallet provides several hours of unmanned production.
Saint-Gobain 'Aulos' grinding wheels - Saint-Gobain developed a new range of wheels which exceeds the performance of the currently standalone CBN wheels.
Aulos is designed to maximise productivity from modern standalone CNC centres.
The patented long aspect ratio ceramic abrasive provides a very free cutting, open wheel face enabling flute grinding speeds significantly higher than possible with CBN wheels.
Feed rates of 1200 - 200mm/min and depth pf cut of 4-6 mm have been achieved.
They also meet the stringent requirements for the metallurgical integrity of tools that will be given long life TiN coatings.
