Greetings!

Welcome to the December 2009 copy of the Some Times Newsletter.

We hope you enjoy catching up with the updates from the World of Ultra Tec each month!

 


NEW PRODUCTS - a CONCAVE FACETING MACHINE, and a FANTASY FACETING MACHINE
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Yes, TWO new things - two, because they just "go together". We thought about these, and we spoke to professional cutters, and we got a very good response -and we were blessed with several "wish lists" in terms of the features they'd want. We were blessed with good engineering ideas, too. We knew-and they confirmed--that precision and repeatability were critical elements-just as they are on a standard faceting machine.

 


Andrew Gulij sat at his Ultra Tec V2 Andy Gulij of San Diego was a major contributor-and when he was involved as the "test pilot" for the prototype units, he brought a number of important details to our attention-a longer range of travel, a higher speed of reciprocating-practical hands-on advice.

Not the least important was the top item on his wish-list: a "Cheater" (I like to call it a "tweaker") that provides fine adjustment of a concave facet's position-linear and radial--directly analogous to the cheater on a flat faceting machine. We did it.

 


Jeff Graham Another key feature was on the wish-list of the late Jeff Graham. We discussed it a year ago and Jeff was immediately interested in the project, particularly the Fantasy Machine - he said he had designs in mind that he wanted to pursue.

 


Fantasy horizontal index Jeff provided the idea of accurate and repeatable horizontal angle indexing - something we've accomplished by means of a mechanism similar to the Index Gear on the Faceting Mast.

 


The direct precision and calibrated settings of these machines save time, but, in general-depending on complexity, these stones, as compared to flat faceting, take a much longer time to finish (you will see that they command a high price, reflecting that situation). But, results can be spectacular, and your efforts and patience are dramatically rewarded.

We will be at the TUCSON GEM AND MINERAL SHOW in February-you may want to see them there. You may have questions now-email us. We'll answer all.

 


The CONCAVE FACETING MACHINE
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

Concave Machine The CONCAVE FACETING MACHINE allows for the adding of concave curves to facets previously cut on a flat standard design. This is a pretty straight-forward operation that any faceter, with some practice, can do nicely. There aren't many instruction diagrams-there will be more on the way--but mostly, the faceter makes judgments on which facets to do, and soon develops an understanding of "what happens" to the appearance-and soon develops more ingenuity and originality to the design.

When the preliminary work on the faceting machine is complete-essentially, a preparation of the perform--the Mast is transferred to the Concave Machine (as shown in the photo)

 


 

Some Features of the CONCAVE FACETING MACHINE

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

Pink concave cut An Alignment Tool positions the Quill to the Tool axis- setting a "home position" in less than a minute

Tool rotation speed is controlled independently from speed of tool reciprocation-separate motors

A "Rigidizer" fits to the Ultra Tec Mast, eliminating swing (which needs to be held steady for the concave faceting) and flexing of the Riser Block-it takes less than a minute to mount, and all functions remain operable

The Mast mounts on a "Tweaker" Block (a "cheater", if you like) with angular adjustments of +/- 2 degrees, and linear adjustment of +/- 2 mm

Adjustable Splashguard height position

Electrical operation: 110VAC/220VAC

 


ridgidizer Certain features of the Fantasy Machine can be subsequently installed-for example, the calibrated X control (in-out).

 


 

The FANTASY MACHINE

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ULTRA TEC FANTASY MACHINE The FANTASY MACHINE allows for "whatever you can think of" in terms of the stone design-(including that it can be used as a Concave machine--when the faceter is not on a flight of fancy). Most typically, a relatively simple perform is made on your Faceting Machine, and then your Mast is transferred to the Fantasy Machine (as shown in the photos). Then-it's what you can dream of. In combination with the faceting Mast, there are the three linear positionings (XYZ) and three angular positionings (axial, radial, and planar)- all settable and repeatable.

 

 

 

 

 

 


cropped green quartz use this The Tool Motor can mount in two positions, one, so that reciprocation is in line with a cylindrical tool (as shown in the photo below) and a second position (lower photo) in which reciprocation is in line with a grooving type (like a saw blade) tool. The stone's design is limited only by the faceter's imagination. The stone can be asymmetric-curves, dimples, holes, grooves, channels-whatever. There are no standard designs-(but many fantasy cuts can be seen on the web-stimulation for directions to go)

 

 


Some Features of the FANTASY MACHINE
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

fantasy-alt-image An Alignment Tool positions the Quill to the Tool axis- setting a "home position" in less than a minute

Tool rotation speed is controlled independently from speed of tool reciprocation-separate motors

A "Rigidizer" fits to the Ultra Tec Mast, eliminating swing and flexing-less than a minute to mount

The Mast mounts on a "Tweaker" Block (a "cheater", if you like) with angular adjustments of +/- 2 degrees, and linear adjustment of +/- 2 mm

Adjustable Splashguard height position

Dial-in positioning of Y direction and X direction-allowing fine adjustment and repeatability. Y travel (in-out) of 150 mm. X range (faceting range on long stone), +/- 25 mm.

Dual positioning of the Tool Motor-at 90 degrees- maintaining reciprocation in line with the cutting axis. Repositioning of Motor takes less than a minute

Planar angle setting through 180 degrees, in 5 degree increments

Tool Reciprocation range adjustable, 0 to 30 mm

Electrical operation: 110VAC/220VAC

 


The photos in this announcement are all from the pilot run, and these machines are all spoken for. Deliveries of production units are planned for February.

Modifications? All the operational mechanical features are proven, and are as you see them -- we've been testing and testing. There are several configuration changes scheduled for production units. For example: the X setting length will be increased an inch (Andy Gulij, in testing, said it felt a little tight); the metal enclosure for the reciprocating motor will be reduced in size: and several others (including configuring the CONCAVE unit so it can upgraded to some of the features of the FANTASY unit).

The Concave Machine, item number 2627.7, price $2,280.

The Fantasy Machine, item number 2648.7, price $3,680.

 


A "PRETTY ROCK" COMPETITION
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Devin McRorie has announced a new idea in faceting competition-an almost revolutionary idea in faceting competition.

Devin's business IS "Pretty Rock" - (He's located in North Carolina, and his interesting website is www.prettyrock.com ), and the Competition is appropriately named "Pretty Rock". It has an interesting twist to it. On the website, Devin writes: "Unlike many faceting contests, this is not about perfection. This is an old-fashioned beauty contest. After all we are PrettyRock.com not perfectrock.com! If you cut a stunner of a stone, but some of the meetpoints don't match, you still have a solid chance of winning.

PRIZES! Even if you don't enter the contest, you'll enjoy reading about it-the approach to judging is novel. Read about it on his website. Many cutters steer clear of competitions-it makes them nervous-but here's one not to be nervous about.

Read on...


EXHIBITION IN SRI LANKA
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
bmich convention center "JEWELS 2009" is the name of the Gems, Mineralsand Jewellery exhibition and competition being held on the 12th and 13th December at BMICH Colombo. There will be a free gift of a gem with every entrance ticket of Rs 50/=.

The exhibition is organized by the Gemmologists Association of Sri Lanka (further details 0117202032 or info@gemmology.lk).

Ajith Siriwardena, Past president of the Gemmologists Association of Sri Lanka-and the Ultra Tec Representative in Sri Lanka will be there.
