Adjustable ER Nut - Absolute Zero Nut

You can now dial in your part or cutter to "zero" it out. After you get your new ER nut, just chuck your part or
cutter, place an indicator on it to locate "out of round" and adjust as the needed set screw(s) to zero out. It's
that easy. Your parts can are now super accurate and you mill cutters can last longer with better accuracy!

Collet Wrench For ER25
Abosolute Zero Nut

ER32 Collet Wrench (+$14.00)

Finally, you can now "Zero Out" your work piece on a Qty 1
lathe or a cutter for milling (great for our ER
headstocks and any ER tool holders). See, here is the Share
beauty of the new GlockCNC Absolute-Zero-ER Nut;
you can compensate for both the spindle and collet
runout…plus, you are able to zero-out the runout at the
furthest tip of the part or cutter. As you know, runout is
greatest farthest away from the collet chuck. Just put
your test indicator at the furthest part, measure and
adjust.

Here is how it all works. Our special collet nut has two

major pieces; the outer nut with threads and the inner

compression ring (the whole assembly is held together

by a retention ring). There are 6 socket head set

screws around the outer edge ER nut. Back all of them

out until the top of the set screw is flush with the collet

nut surface. Tighten the mounted collet nut onto the View detailed images (11)

work piece or cutter. Place your test indicator at the

farthest point of what you are clamping. Turn the

spindle to see where your part or cutter is “out of

round” and hold it there. Simply adjust the corresponding set screw to zero out the part or cutter on the test

indicator. Do this for any area that is out round. That’s it.

Here’s the secret. The set screws don’t press on the collet. They press on the inner collet compression
ring. This uniformly adjusts small areas of the collet. This allows you to compensate for spindle and collet
error. You see, the spindle will have a certain amount of error and so will any collet. When you put the
collet in the spindle, you add error on top of error. This is call stacking. Your new Absolute-Zero-ER nut is
your solution for this. It can compensate for that combined error (of course, if your spindle, part or cutter is
too far out of whack, then you may still have some error…makes sense right?).

Uses:

Lathes

Zero out the actual work piece for super accurate work

Great where you must have absolutely the highest accuracy or small parts where you can’t afford to lose
too much material

Mills

When your end mills are dialed into Zero, your end mills will last longer. This is because all flutes are
cutting evenly. If your end mill isn’t turning true, that means some flutes are doing most of the cutting while
others aren’t. This means flutes that are doing most of the work will wear out more quickly.

More accurate finished products. If your cutter is actually moving in an oblong fashion instead of round; you
will have an in accurate finished part. It will remove more material than you may have planned on. You can
now get the accuracy similar to a shrink fit tooling system without the major investment. All by using our
Absolute-Zero-ER nut

Look, we understand that buying ultra precision components aren’t cheap...and this is no exception. But if
you require absolute accuracy; then this could end up being the cheapest investment you could make
toward that end, period.

Available in ER40, ER32 and ER25. Requires collet nut wrench one size bigger than stock. In other words,
the ER40 version will require an ER50 collet nut wrench, ER32 needs ER40, ER25 needs ER32. Collet
wrenches are available for all sizes.

(Quick side note; these are made in batches and are in demand. It’s best to you as many as you want and
order as soon as possible. All are sold first come first serve before going on the waiting list. This price is for
the collet nut only, headstock in images is sold separately.)

The Sherline headstock is a good little headstock, but Qty 1
it’s a bit too small for some needs. Because of the
demand for a more robust headstock with larger Share
bearings; we introduce the Glock Billet Headstock. It
has all the mounting features of a stock Sherline
headstock to keep it completely compatible with
Sherline products. Plus, it has additional mounts for
custom machines. The differences are as follows:

You can now have a more robust 3.5”W x 3.5”T

x 3.0”L, that’s a full 1.00” wider and taller (0.50”

on each side & 1.00” taller than a stock Sherline

headstock, center is still 1.75”)

Larger 62mm OD bearings for heavier work load

and superior wear, so you can use heavier

chucks, parts or cutters (stock is only 42mm

OD)

Available in deep groove, angular contact (both View detailed images (10)
in ABEC-5 or ABEC-7) and heavy load taper

bearings

(4) ¼-20 threaded mounting holes on the bottom

of the headstock for superior rigidity on custom setups

Recommendations:

While not necessary, we do recommend using at least a 600 watt motor for this (we offer 600 watt to
1,400 watt options). The bearings are much more heavy duty. If you choose to use a stock Sherline
motor, it will work, however you will need a longer belt (it will directly mount, holes are in the same
place and size as on a stock Sherline headstock)Pulley - Many opt for a timing pulley set. You may
also adapt a stock Sherline pulley.
We offer both V groove & timing pulley taper lock sets and adapted Sherline pulleys.

Options:-

ABEC-7 super precision deep groove bearings (standard bearings are ABEC-5)
Large Bore
Sherline stock pulley bored to fit spindle
ER32 Adjustable collet nut
Timing pulley - please ask

Please note: Because of heavy demands, please expect about a 4 week build time.

screws around the outer edge ER nut. Back all of them

out until the top of the set screw is flush with the collet

nut surface. Tighten the mounted collet nut onto the

work piece or cutter. Place your test indicator at the View detailed images (11)

farthest point of what you are clamping. Turn the

spindle to see where your part or cutter is “out of

round” and hold it there. Simply adjust the

corresponding set screw to zero out the part or cutter on the test indicator. Do this for any area that is out

round. That’s it.

Here’s the secret. The set screws don’t press on the collet. They press on the inner collet compression
ring. This uniformly adjusts small areas of the collet. This allows you to compensate for spindle and collet
error. You see, the spindle will have a certain amount of error and so will any collet. When you put the
collet in the spindle, you add error on top of error. This is call stacking. Your new Absolute-Zero-ER nut is
your solution for this. It can compensate for that combined error (of course, if your spindle, part or cutter is
too far out of whack, then you may still have some error…makes sense right?).

Uses:

Lathes

Zero out the actual work piece for super accurate work

Great where you must have absolutely the highest accuracy or small parts where you can’t afford to lose
too much material

Mills

When your end mills are dialed into Zero, your end mills will last longer. This is because all flutes are
cutting evenly. If your end mill isn’t turning true, that means some flutes are doing most of the cutting while
others aren’t. This means flutes that are doing most of the work will wear out more quickly.

More accurate finished products. If your cutter is actually moving in an oblong fashion instead of round; you
will have an in accurate finished part. It will remove more material than you may have planned on. You can
now get the accuracy similar to a shrink fit tooling system without the major investment. All by using our
Absolute-Zero-ER nut

Look, we understand that buying ultra precision components aren’t cheap...and this is no exception. But if
you require absolute accuracy; then this could end up being the cheapest investment you could make
toward that end, period.

Available in ER40, ER32 and ER25. Requires collet nut wrench one size bigger than stock. In other words,
the ER40 version will require an ER50 collet nut wrench, ER32 needs ER40, ER25 needs ER32. Collet
wrenches are available for all sizes.

(Quick side note; these are made in batches and are in demand. It’s best to you as many as you want and
order as soon as possible. All are sold first come first serve before going on the waiting list. This price is for
the collet nut only, headstock in images is sold separately.)

The Sherline headstock is a good little headstock, but Options
it’s a bit too small for some needs. Because of the 2 Step Bored Sherline Pulley
demand for a more robust headstock with larger
bearings; we introduce the Glock Billet Headstock. It (+$49.00)
has all the mounting features of a stock Sherline ABEC-7 super precision deep groove
headstock to keep it completely compatible with
Sherline products. Plus, it has additional mounts for bearing set (+$197.00)
custom machines. The differences are as follows: Large Bore .790" (+$49.00)
Adjustable ER40 nut (+$224.00)
You can now have a more robust 3.5”W x 3.5”T
x 3.0”L, that’s a full 1.00” wider and taller (0.50” Qty 1
on each side & 1.00” taller than a stock Sherline
headstock, center is still 1.75”) Share
Larger 62mm OD bearings for heavier work load
and superior wear, so you can use heavier
chucks, parts or cutters (stock is only 42mm
OD)
Available in deep groove, angular contact (both
in ABEC-5 or ABEC-7) and heavy load taper
bearings
(4) ¼-20 threaded mounting holes on the bottom
of the headstock for superior rigidity on custom
setups

Recommendations: View detailed images (17)

While not necessary, we do recommend using

at least a 600 watt motor for this (we offer 600

watt to 1,400 watt options). The bearings are

much more heavy duty. If you choose to use a stock Sherline motor, it will work, however you will

need a longer belt (it will directly mount, holes are in the same place and size as on a stock

Sherline headstock)Pulley - Many opt for a timing pulley set. You may also adapt a stock Sherline

pulley.

We offer both V groove & timing pulley taper lock sets and adapted Sherline pulleys.

Frankly, they are a bigger investment and not many
sources can custom grind this at the level of precison
we demand (we found a few others, but the cost was
outrageous). It's not for everybody. On flip side, if you
need the size capacity and precision, than nothing else
will do....
