The Darex Story

The Darex Story

Darex Corporation began in 1973 in Beecher, Illinois. The D, A and R of Darex are the initials of three
generations of the Bernard family; David, Arthur and Richard Bernard. David and his father Richard
founded Darex. Grandfather Arthur Bernard, who earlier founded the Bernard Welding Company, contrib­uted his energy and guidance to Darex. Art’s inventions revolutionized the welding industry.

In 1978, Darex relocated to Ashland, Oregon. Grandson Dave and son Dick carry on Arthur’s legacy of
inventiveness. Darex grew to become the most recognized name in the cutting tool sharpening industry.
Today, Darex is a world-leading manufacturer of precision cutting tool sharpeners.

Darex is proud to offer a complete line of quality precision cutting tool sharpeners at affordable prices.
Before our first days, we at Darex had looked at our competitor’s sharpeners and asked ourselves:
“Must cutting tool sharpeners be complicated? Why must the choice be limited to cost prohibitive accu­racy or low price inaccuracy?” Our sharpeners prove you can have it all: Simplicity, Accuracy, and Af­fordability.

We have always emphasized innovative product design and tested tech n olog y. The experien ced person­nel at our modern manufacturing facility use the latest production methods. The Darex marketing team
knows first-hand the machines we sell and will guide you to the best machine for your needs. Our skilled
technical service department is happy to answer your questions about our products or cutting tools.

The XPS-16 CNC Sharpener

The Darex XPS-16 CNC Drill Sharpener can be programmed to sharpen an infinite variety of conical, four-facet,
split-point and/or radius split point drills. The XPS-16 can sharpen HSS and c arbide twist drills from 1/8” to 5/8” (3­16 mm) diameter, 2” to 8 ¾” long, and angles of 90 to 150 degrees. Memory stores user-defined drill point ge­ometries. In a single set-up the Darex XPS-16 automatically sizes, aligns, then sharpens the drill and splits the point
and can hone the drill’s cutting edges to minimize chipping. Benefits include: Convenient internal chuck holds drill;
LCD screen display panel for one-touch programming; Long-lasting super-abrasive plated grinding wheels; “Grind
Motion Control” monitors load on the grinding wheel; adjusts feed and speeds keeping drills cool, di agnostic soft­ware alerts operators of potential problems.
To keep your Darex XPS-16 in top condition, please refer to the maintenance section of this manual. Replacement

wheels and parts are listed in the parts list on page 83 & 84. A schematic breakdown of the machine is on page 85
of the manual.

Safety Instructions

Safety Instructions

GROUNDING INSTRUCTIONS

• For all grounded, cord connected tools:

• In the event of a malfunction or breakdown, grounding provides a

path of least resistance for electric current to reduce the risk of
electric shock. This tool is equipped with an electric cord having
an equipment-grounding conductor and a grounding plug. The
plug must be plugged into a matching outlet that is properly in­stalled and grounded in accordance with all local codes and ordi­nances. Do not modify the plug provided-if it will not fit the outlet,
have the proper outlet installed by a qualified electrician . I m ­proper connection of the equipment-grounding conductor can
result in a risk of electric shock. The conductor with insulation,
having an outer surface that is green with or without yellow
stripes, is the equipment-grounding conductor. If repair or re­placement of the electric cord or plug is necessary, do not connect
the equipment-grounding conductor to a live terminal. Check with
a qualified electrician or serviceman if the grounding instructions
are not completely understood, or if in doubt as to whether the
tool is properly grounded. Use only 3-wire extension cords that
have 3-prong grounding plugs and 3-pole receptacles that accept
the tool’s plug. Repair or replace damaged or worn cord immedi­ately. See Table 1. Minimum Gauge Cords below.

• Grounded, cord-connected tools intended for use on a

supply circuit having a nominal rating less than 150 volts:

This tool is intended for use on a circuit that has an outlet that
looks like the one illustrated in Figure A. The tool has a grounding
plug that looks like the plug illustrated in F ig ure A . A tem p orary
adapter which looks like the adapter illustrated in Fig ures B and C,
may be used (except in Canada) to connect this plug to a 2-pole
receptacle as shown in Figure B if a properly grounded outlet is
not available. The temporary adapter should be used only until a
qualified electrician can install a properly grounded outlet. The
green colored rigid ear lug, etc. extending from the adapter must
be connected to a permanent ground such as a properly grounded
outlet box. See Fig. 1. Grounding methods below.

• Grounded cord-connected tools intended for use on a sup-

ply circuit having a nominal rating between 150-250 volts
inclusive: See Table 1. Minimum Gauge Cords below.

XPS-16 Auto Measurement Features

Your XPS-16 has many features so carefully designed and engineered that you may not even be
aware of their uniqueness. Once the cycle start button has been pushed, your Darex XPS-16 be­gins taking measurements of the drill, on the way to the grinding wheel. Your XPS-16 locates the
end of the drill, calculates diameter, locates and positions the cutting edge, determines web thick­ness, identifies initial contact point of drill to the wheel and then sharpens. After sharpening and
before splitting the drill, your XPS-16 sharpener again measures and re-locates the end of the
drill, ensuring an accurate split.

Grind Selector

• With each touch of the button

you will bring up the next point
style option. The
style options: Conic or Facet

NOTE: Factory default is “CONIC”.

• “CONIC” – This radial/cone style grind is

known as a conventional point
through out the machine tool industry. A lip
clearance of 12° to 15° at the periphery of the
drill, increasing constantly toward the center,
is considered standard for the average
class of work.

• “FACET” – Multi faceted drill points

consist of a separate cutting lip (primary)
and secondary heel clearance (relief) facet.
The multi-faceted drill requires 150% less
thrust and produces 70% less heat than a
conventional drill.

• The width of the primary facet is determined

by the thickness of the drills web and cannot
be changed. If your drill has a thin web, we do
not recommend a facet point style. The width

Split Point Selector

• With each touch of the icon

you will bring up the next
split style option. There are
3 split point options: No Split, X- split
(Standard) and R- Split. (Radius) The XPS-16
will produce a chisel angle ground to
approximately 130°.

NOTE: Factory default is “SPLIT”.

• “NO SPLIT” – Select when reproducing a

non-split drill point style.

• “X-SPLIT” – 4° split point rake angle is

created, producing a drill with a self­centering point. Its advantages are the
ability to reduce thrust and eliminate walking
at the drill point. This is a distinct advantage
where drilling bushings/fixtures are not used.

• “R-SPLIT” – The R-split selection is not

an option until the web thickness value
has been manually entered. Changing
the amount of radius and rotation is
adjustable. This is done in the Split Point
Offset screen . Refer to information on

page 35 for details.

• An R-split will produce a drill with a self-

centering point as well as act as a chip
breaker producing smaller chips, which can
readily be ejected. The radius will assist the
flow of chips and reduce chip impaction at the
tip of the drill.

Relief Screen Selector

• Select lip relief clearance from 5° to

18° +/-2°. The diameter and the point
angle will determine the degrees of
possible relief. See tables below.

NOTE: The degree of relief entered, will ap­pear on the relief selector button on the
main screen menu.
