Summary
Choosing the best veneer is a very challenging and very personal decision. You must first evaluate the different qualities of different machines and then decide which factors are most important to you.
multifaceted experience.
Reading time: 14 min 25 sec
qualities
Before we look at the machines, let's define each of these qualities: Repeatability, Reliability, Speed, Accuracy, Cost, and Uptime.
repeatability
This means that every time you cut a stone, the same actions create the same effect. You don't have to reinvent the wheel every time you want to cut a round brilliant. Repeatability also means that there is some sort of reference point that guides you through the cut.
reliability
This means that if you buy a new machine, you'll still have a working machine in 1 year, 5 years, 10 years, and hopefully 20 years or more. Most carving machines will last a long time if you take care of them. Reliability also includes accuracy throughout the life of the machine and supplied accessories.
speed
It means how fast you can cut a stone. When comparing faceting machines, we will find that the biggest challenge is the balance between speed and accuracy.
precision
It means how well the machine will help you cut a perfect stone. We use carving machines because it's very difficult to create straight faces in a rock by holding it in your hands.
Cost
Along with speed and accuracy, cost is probably one of the most important decision-making factors. Cost tells us how much money we have to pay for a new machine, including shipping, import taxes and accessories.
Availability
Some of the best machines ever invented are no longer available for purchase because they are no longer manufactured. This will influence your decision, because buying a used car is a completely different ball game with different risks than buying a new car. In almost all examples in this article, we assume that you are buying a new machine from the manufacturer, as any other comparison would be unfair.
types of machines
In short500 years of gemstone grinding technologySo let's divide modern incarnations into three distinct categories: the pole machine, the jam machine, and the handpiece machine.
the mast machine
This type of machine comes from countries that grew up with competitive cutting cultures, such as the United States, Australia and Russia. These machines are by far the most accurate for cutting stone and are also typically the most expensive. Unfortunately, speed greatly affects the accuracy of these machines. Mast machines are slower and less forgiving compared to other machines. They are quite easy to learn and are great for amateur tailors. However, they are completely unsuitable for rapid production/cutting.
the jelly machine
These are the more traditional types of clippers, although not all jam pegs are created equal. Because they are the fastest, these machines are best for production, but they sacrifice accuracy. While jam-pin machines can be very accurate depending on the technique, they tend to be less workable and time consuming to master across the board.
hand machine
The handpiece machine is the perfect compromise between the mast machine and the locking pin, in my opinion. Compared with the best jam peg machine, the handpiece machine is more accurate, repeatable and accurate. Compared to a pole machine, the handpiece machine will always be faster and more adaptable in its operation, as you can easily move the handpiece to get the best view of the stone while cutting. Also, from a production standpoint, it's very easy to take the stone out and put it back in the handpiece or move the handpiece from the cutter to the polisher on a grinding machine.
In case it isn't clear, my preference has shifted from the rod machine to the handpiece machine in recent years as I've been more exposed to them. I believe the handpiece offers the best compromise between all quality factors. However, I will remain as open as possible when reviewing each machine in this article.
mast machines
Ultra Tec V-2/V-5
The Ultra Tec is probably the most famous carving machine in the world. Though often considered the best machine, every facet that ever existed has had its merits debated. The V-5 machine has a digital readout that tells you exactly what angle you are cutting, and many people love this feature.
Over the years, Ultra Tec has updated various parts of the machine, keeping it backwards compatible and upgradable. The machine's current incarnation has a stout neck that resists bending and generally lives up to its reputation as a big machine. It's also the most expensive machine you can buy right now. You can easily find many used machines in working order from the 1980's, which tells us that this machine will likely continue to cut rock long after you retire.
Ultra Tec's customer service can be bad or bad, and it seems like every part of the machine is proprietary, meaning if something breaks, you have to ask the company for it. Many of these small parts, including nuts and bolts, are not as cheap as other manufacturers.

facetron
Another popular gemstone grinding machine, the Facetron, doesn't offer any of the high-tech features that other manufacturers have introduced. However, it is considered to be a very reliable machine.
The depth gauge helps make cutting fast and repeatable, and I've seen some of the finest stone in the world cut on this machine. It's more affordable than the Ultra Tec, but with fewer 21st century features. It is reliable and many cutters keep the same machine for the entire life of the cut.

Tumbas MarkIV/5XL
The Graves Company is one of America's oldest carving machine manufacturers. These machines have gone through several improvements over the years. With the introduction of the Mark 5XL, it now offers a well-designed digital angle gauge at a very low price. Digging machines are generally highly valued over pruning machines due to their cost and the fact that they work well.
In recent months, there have been problems with the Graves company. Many people advised against placing orders with the company, as orders can take up to 6 months or more to fulfill. If you can find a new machine at a dealer, that's the best choice.

Polymetrischer Centereller
This machine gives the Ultra Tec a run for its money. The scintillator features a digital readout for accurate cutting angles, as well as a Facetron-type depth readout that lets you quickly cut an entire layer of facets to the same depth. The neck is strong and the quick release knob on the neck head means you don't have to turn it for 5 minutes if you want to jump up and down the neck to go from headband angle to crown angle. The whole machine has a strong industrial feel and is well made.
The company is very easy to deal with and the machine is reasonably priced when in need of spare parts or maintenance. Due to its mostly metal construction, this is probably the heaviest neck sculptor out there. Having to travel with the scintillator can present some challenges.

Faceta GemMaster II
It's hard to talk about the GemMaster II at this point as the machine has been discontinued. However, the company now has a new owner and the machines will be available again soon. The GemMaster II is like the holy grail of carving machines. They are rare, uncommon, and seem to infuse their wielders with a certain spiritual enlightenment that allows them to quickly carve very beautiful stones.
The GemMaster is not a mast machine with its unique radial arm where the boom slides down. The machine also has an electric depth gauge (similar to a BW gauge) that tells you how close you are to your desired angle. The machine must be very fast and easy to use. Many, having learned about this, refuse to use other types of machines.
When the new version of the GMII is released, we'll see if it lives up to its reputation. Previously, these machines were only available on the second-hand market, but soon you will be able to order a new edition from the manufacturer.

VJ Lapping Machine
This appears to be the Australian equivalent of the GemMaster II. I haven't used or seen this one, so I'm copying the following from their website:
Used by the most demanding veneers around the world. A different concept that offers unparalleled and repeatable accuracy and ease of use. Suitable for all levels of lapping experience, from beginners to commercial and competitive lapping. No moving columns. Directly readable angular scale up to one tenth of a degree without vernier. From the belt to the table without moving the handpiece head. Minimal vertical stone movement when changing angle. It takes 6" or 8" turns.

Jam Peg Machines
the blink
The French developed this type of jam clip (known asCairin French) with the mechanical stick, and this is the latest version. The machine is driven by an electric motor (as opposed to a traditional hand crank). The head has either 17 or 33 notches, offering a wide range of preset angles. If you need to switch between preset angles or "cheat" slightly left and right, there are knobs on the head that let you move the peg holes in any direction. The strength of this machine lies in its speed due to the mechanical lever that allows it to face very, very quickly.
The manufacturer also offers courses to teach how to cut with this machine. Once you learn how to use it, the Adlap is the fastest machine you can buy. A master will be able to facet very accurately, although it may take years to become an expert rather than the months it would take with a pole-type machine.

to sit
This is the Thai version of the French machine. The main advantage of this machine is that it is very inexpensive. The accuracy is lower than the one made in France and the machine is very heavy because it is built into a table and needs a separate independent motor to run. The index wheel, which allows for quick cutting, is made of plastic rather than metal, but the price seems to make up for it.

Bhandasa
The Israelis took the French pen and took it to the next level of innovation. They made the whole head stronger and added 64 teeth to the mechanical staff, so you can quickly grind 8 facets against the index of the mechanical staff, and then move the stone very precisely from 1 to 4 teeth around the index to quickly cut the star or belt. aspects

hand machines
Imahashi
Imahashi has developed this kind of tabletop handpiece carving machine. The machine uses a well-designed handpiece that allows the cutter to control angle and speed, as well as allowing for "cheating" by adjusting the height of the handpiece feet.
This machine has a solid reputation and is easy to learn and use. They have two different types of handpieces, one with a built-in cam for perfect pre-shaping and a regular one that just cuts at an angle. The metal plate the handpiece sits on is moved up and down to control the depth of cut by turning the brass knob on top of the riser plate handle. The downside of this machine is the price.
- Cost: approximately $4,000 (shipping from Japan)

Raytech Shaw
This American-made machine is similar in concept to other handpiece designs, but executed slightly differently. This machine stands on its side compared to other handpiece bases. The handpiece is the lightest I have ever seen. The downside is that it also feels a little less massive and industrial.
I've heard complaints that after a little use of the machine, theDopingit starts to wobble on the pin and causes surface grinding problems. However, this can only happen on certain machines. In the machine, the lifting plate moves up and down by means of a rotating wheel under the lifting plate, so that the stone does not hit any pins.

Pound sterling
The Sterling machine is the latest development in handheld machines from Sri Lanka. They offer different handpieces for different purposes: some with a cheater, some for small hands, and some just standard. This is a robust, well-made workhorse of a machine that can easily run 24/7 in a production environment for decades. It has the ability to cut rocks quickly and with great precision.
Cutting perfectly accurate stones isn't as easy as with a pole-style machine, but once you master the art of cheating by adjusting the height of the foot, you can achieve pole-precision. This machine cuts light years faster than any pole machine I've ever tried. I've seen a master cutter face five 20-carat gems precisely cut on this machine in one day.

more colorful
When it comes to the best lapping machines, I couldn't resist adding them to the list.
Let's get the cons out of the way first. The machine has a pre-owned value of approximately $10,000 (including attachments and twists) and is no longer available. He is also incredibly heavy and uses his own special spins and dops which are also incredibly heavy.
Now for the pros: this is the best carving machine ever made. I leave it like that.
The Bunter was made in Switzerland to cut large and small stones to tight tolerances for the watchmaking industry. The vertical twist means the stone is right in front of your face at all times, making it easy to see. Separate cutting and polishing wheels mean you never have to change tips, saving time. The handpiece's incredible, lightweight design does it all, including cheating, engraving, and shipping without an adapter.
The machine is so well made that the makers practically went bankrupt because once you buy one, it never breaks down, so they never made any money again. If you've seen one of these, just buy it and practice. You will not regret.

Diploma
The real question is not which is the best carving machine, but which is the best machine for your needs. I think most people asking this question only consider pole-style machines, so I've included other types in this article in hopes that they'll broaden the horizons of new trimmers.
One thing that should be clear is that each machine has its own traditions and techniques and they are not always interchangeable. Sometimes when you don't understand a machine's technique you might think you're no good, so I think the last question an editor should ask is "Who is my teacher and what techniques can he teach me?"
I currently use a polymetric scintillator and a Bunter machine at home and a Sterling machine at work. I cut a stone on most of the machines listed here. My conclusion is that cutting with a handpiece machine is more fun and also faster, meaning you can cut more stones per week. I also think you could win a competition with a manual machine, although that means a little more sweat.
I went from using an Ultra Tec to using and loving the Poly-Metric to using and loving the Sterling machine. It's a great machine to use and, above all, a great machine to learn because it's simple and easy to use.
