CNC 4-axis drill sharpener with an easy-to-use touch screen panel easily reproduces the complex, high quality points found on today's premium HSS and carbide drills.
The 1st MTA company demonstrated the Darex XPS-16 CNC drill sharpener, which, said the company, carries out the advanced CNC 4-axis sharpening of a wide range of twin flute drill point types using simple, one-touch operation.
The XPS-16's advanced CNC operation enables it to easily reproduce the complex, high quality points found on today's premium HSS and carbide drills.
1st MTA told manufacturingtalk that an easy-to-learn touchscreen interface allows even novice users to produce perfectly re-sharpened drill points in seconds.
The XPS-16 is suitabel for conical, four facet, split point and radius split point bits with angles from 118-150 deg as standard.
A 90-118deg add-on option is also available.
1st MTA said that the XPS-16 will sharpen HSS, cobalt and carbide drills from 3-16mm diameter and 50-220mm long.
It has been designed specifically for heavy duty use within busy machine shop environments and is can sharpen more than 400 drills/day.
* Easy operation - a blunt drill is first inserted into the sharpener's chuck and the required drill point type selected using a simple touchscreen panel.
On initiation of the sharpening cycle, three independent electronic sensors automatically detect the drill's length and diameter; precisely locate the cutting edge and calculate the web thickness.
The unit then sharpens the drill and applies the required split point form, in one seamless operation.
The XPS-16 will also hone carbide drill edges as part of the automatic process - extending tool life and maximising drill bit machining accuracy.
* CBN and diamond wheels - the machine is equipped with CBN and Diamond wheels that are designed to sharpen 2,000 to 4,000 drills.
Metal removal is set at a minimum to extend drill life.
However, this can be overridden by up to 0.50mm if necessary, to compensate for gouges or nicked drill edges.
The XPS-16 allows user-specific drill sharpening programs to be produced easily and stored for future use.
It also has Darex's latest Grind Motion Control system, which detects excess material on the blunt drill bit.
The system enables the grinding feed rate to be adjusted automatically, to prevent abrasive 'burning' and to provide optimum sharpening performance.
* Low maintenance - the unit's long-lasting super-abrasive plated grinding wheels and lifetime-lubricated seals ensure low maintenance and a long service life.
The sharpener also incorporates a vacuum filtration system to eliminate grit and airborne contaminants such as carbide dust.
In addition, its computerised controls are backed by advanced diagnostic software that will alert operators to potential problems during the sharpening cycle.
