R-8,
5C,
ER-40 & ER-16
(⅜") collets.
R-8 & 5C collects are indexed to prevent turning.
ER-type collets have wide gripping ranges
& self-extract.
70 piece 5C collet set 3/64"
(0.046875") through 1-1/8" (1.125") in 1/64ths (0.015625")
increments.
A 5C collet has a relatively small gripping range. Best accuracy is +0 to -0.002"
Above +0.005" may damage the work, below 0.010" may damage the
collet.
1/32" (0.03125") increments are too large of steps. Most 5C collets are open all the way
through.
An emergency 5C collet that can be machined for a specific
use. A set of square, 5C collets.
Phase2+
spin index that uses 5C collets. Hardened & precision ground spindle.
Spindle accuracy 0.0004" TIR. Cylindrical center base (per inch) .0012"
concentricity.
Spindle centerline parallelism to base 0.0008". Precision ground 36 position index
plate.
Direct indexing in ten steps, graduated in 5 degree increments.
Excellent price to performance ratio.
Used a ball-nosed end mill so the bottom of the slot would
have a radius.
Milled base for flatness & clearance for
mounting bolt nuts with coupled washers.
Spin index mounted onto Taig mill which has 1
inch on-center T-slots. Bolts are 2 inches (slots) apart.
The spin index fits the larger
RF-25, much better (below).
Milled ⅜" bolt-down slots.
This is a good place to use the ¾" shank,
ER-16 extensions.
Four-sided &
six-sided hardened,
precision ground 5C collet fixtures with
clamping nuts.
Tighten & loosen using the adjustable pin spanner wrench.
Lever moves a cam for faster clamping. These are very useful fixtures.
Quick release 5C collet fixture.
Collet length extension. Adjustable depth stop for a
5C collet screws into back inside
threads.
V-blocks
including wee block set for very small materials.
V-blocks hold round parts very securely.
Variable-angle V-block.
Fixed angle set: 1º, 2º,
3º, 4º, 5º,
10º, 15º & 30º
Precision ground & hardened; very accurate.
Hardened, ¼" thick, precision-ground angle setup plates; 1º, 2º, 3º, 4º, 5º, 10º, 15º,
20º, 25º, & 30º.
Hardened, ¼" thick,
precision-ground 30-60-90º & 45-45-90º angle setup plates.
Can be used with a jig to set up the
lathe's compound angle.
Precision-ground (slotted & solid) angle plates are superior to milled types.
Dowel pins are handy: 3/16", ¼",
⅜", 7/16", ½", ⅝", ¾", 1"
sizes.
