4th axis rotary table for cnc free sample

With this extension, your CNC milling machine gets the 4th axis. That allows you, for example, to mill round parts or create engravings on rounded surfaces.

This rotary axis is made to order for us by a German precision mechanic. In this price segment, this rotation axis for CNC milling machines is unrivalled in Europe!

There are many rotary tables on the market. If possible, they have to be inexpensive. You can get a lot of them! Usefulness? That is where the wheat is separated from the chaff. For example, there are many CNC turntables with the cheapest belt transmission. The disadvantages are obvious: slippage due to the belt. If not in the belt drive itself, then on the load or idle side of the belt. Perhaps useful for engraving work. For milling, however, usually not or limited in the choice of material (aluminium 3D milling not possible).

That means you can use the CNC router for 3D 360° machining in almost all materials. Even round engravings on Plexiglas are possible without any problems with this CNC accessory. That means for our CNC machine users: Round surface milling of plastic parts, wooden parts, aluminium parts or round parts made of brass, as well as engravings of all kinds.

In a four-axis CNC router, there is an additional rotary axis (A-axis) that allows you to do rotary cutting and indexing for making cylindrical/round parts.

You can add the post-processor to the V-Carve Pro software that you get with the Shark HD520 CNC router. It can also be used with software like Aspire which supports post-processor integration.

In most cases, a 4-axis router kit is used to achieve 4-axis machine movement but to control this additional axis you"ll need to have a 4-axis compatible controller.

To put it in a simple form, the standard 3-axis together with the A-axis gives you a 4-axis setup. A-axis is the rotational axis that turns the workpiece.

4-axis machining brings in a great deal of flexibility to your CNC machining process, enabling you to create some of the complex designs that otherwise would not be possible.

4-axis CNC machines are costly because there is a lot of research and development going into building all these machines. You require 4-axis supported controllers, software, and CNC machines to do 4-axis machining.

Also, 4-axis designs require a high precision system to design those models. To make high precision systems you need to use a rigid machine built with well-calibrated electronics. As there are more moving parts in the machine, the operating complexity increases, and a lot of support systems are required to keep the machine running.

In 5-axis machining, two rotational axes operate separately to rotate the workpiece in many different angles with respect to the cutting tool. The machine may utilize either A-axis or B-axis with the C-Axis to achieve this feat, all these are rotational axes.

In 4-axis CNC machining only one rotational axis is there, but with 5-axis machining you can achieve two rotational axes that can operate independently. It brings in a great deal of flexibility in your CNC machining.

Yes, due to the advanced system, a 4-axis CNC requires specialized software to control the movement of the fourth axis. It requires CAM and control software that supports 4-axis machining. To control the machine properly, the software must understand the geometry of the 4th axis and how it relates to the other axes.

Sometimes when using a CNC router to make cuts it is necessary to change out tooling. With a single tool spindle this operation can take valuable production time and introduces another point in the production process for human error to be introduced.

The PHANTOM CNC SYSTEM-ATC CNC machine reduces production time by automatically changing cutters between tool paths, thus eliminating the need for the CNC operator to change and zero tools individually. The ATC feature allows our router to do the full job, even when different tooling is required to make different types of cuts. Signs and complex 3D carvings are a good example of this. A machine equipped with an ATC can perform operations normally done on other pieces of equipment, eliminating the need for additional machines in the shop.

Vacuum tables are common in cnc routers. Besides its firm holding, a vacuum table can also flatten boards and make closed shaped cut-outs more easily without obstructions like clamps in the way of the toolpath.

The vacuum table surface is made from Phenol Resin Panels ( Bakelite ) instead of Hard PVC Boards for better strength and wear resistance. This will provide a longer lifespan in a tough shop environment. The vacuum table can be control with 4 independent gate valves.

PHANTOM CNC SYSTEMS T ATC CNC uses a 1.5M helical tooth rack and pinion system. This allows for smooth high speed, high precision and low noise operation. We use PMI 25 Linear guides with flange sliders on all axis.

The Spindle alone is 22 lbs. After it has been assembled the Z Axis section weighs more than 200 lbs. We use a high precision and high speed ball screw system with a Delta 750 watt drive and brake motor to move the Z axis.

The Z Axis mounting plate is made anodized aviation aluminum. The spindle is fixed on the high-quality aviation aluminum T6061/6063 plate. The Z-axis uses a TBI High-Precision Ball-screw. The ball screw connects to the Nema 34 motor with a disc coupler that protects the ball screw in case of crashes.

We use a stand alone control system that is completely separate of a PC controller. This allows full control of the CNC without worry of Windows updates or controller software updates that could slow down your business.

CNC Routers adopt advanced open-architecture CNC controllers, with built-in high-performance industry computers, LCD screens, and combining with servo axis, spindle, and MPG axis, built-in PLC ( Programmable Logic Controller ) and USB interface, Compact Flash Card reading device.

The roller pressure is distributed on both sides of the spindle, which can effectively prevent the material from moving on the table when processing small materials or materials that are not easily suctioned or clamped. Rollers provide 600lbs of downward pressure.

ATC CNC router has an automatic tool change function including carousel tool change type and linear tool change type. According to the processing requirements, automatic tool change can be realized without manual participation, which further improves the machining efficiency.

2. Put the side of the platform, the diameter of the rotating shaft affects whether the gantry is heightened. If the diameter is large, the gantry needs to be heightened. If the diameter is 10cm, it is not necessary.

3. The table surface sinks as a whole, put the rotation axis under the platform, if carving a plane, place the platform on the rotary axis for carving.

CNC router lathe machine (rotary CNC router) is a type of multifunctional CNC machine kit with 4x8 table size for flatbed full sheet cutting, relief carving, and 4th axis for 3D rotary milling. The T-slot vacuum table is used for board cutting, edging, carving, drilling and grooving, and the rotary device for turning, like a lathe machine. The axis of rotation is the geometric straight line on which the rotationally symmetrical action is performed. The rotary axis is the geometric straight line on which the rotationally symmetrical action is performed.

When the rotation action acts on the image (or molecule), the vertical distance between any point in the image and the rotary axis (line) must always be kept constant. Suppose the base angle of rotation α=2π/n, since the number of independent and unequal rotation motions within the range of 2π angle is "n", the axis corresponding to the basic rotation motion L (2π/n) is called n-fold rotary axis, denoted as "n". The symmetry order of the n-fold rotary axis is "n".

Tombstones correspond to Fixture Plates on a mill.  There are many different shapes and sizes of Tombstones available for 4th Axes.  Here’s one I’ve shown before from a big horizontal milling setup:

I was reading an article about Tombstones in the Tormach blog recently and it got me to thinking about how Tombstones on VMC’s can make a job more profitable.

Tombstones are par for the course on Horizontal Machine Centers, but they’re seen a lot less often on Vertical Machining Centers.  Perhaps it’s because they’re just built into a lot of HMC’s at the factory whereas you have to set one up using a 4th Axis on the a VMC.  The question for this article is how to get a handle on their value?

There’s an old saying that you’re not getting the most return out of your CNC Machine until you have fixtured a job up so that every square inch of the table’s accessible area is being used to make parts.  Put as many parts as possible down for each setup, in other words.  Relying on just a single machining vise, for example, can mean a lot of available table area is wasted versus putting two vises on the table (so you get 2 parts per setup), or two double station vises (so you get 4 parts per setup).  It’s all about how many parts the machine can “chew” on for each setup.  The more the merrier because your setup time divided among all the parts will invariably be less on a per part basis.

On a Tormach PCNC 1100, you get 18 inches of X and 9.5 inches of Y travel.  So, that’s 171 square inches you can utilize for making parts–fit as many in as you can!

Now consider a tombstone like the one pictured above.  It’s like having 4 smaller tables available.  In fact the width of the tombstone is 4″and the length is 13″, so counting all 4 sides, you get 4 x 4 x 13 = 208 square inches.  That’s actually 22% more area than the travels suggest would be available on the table.  So,  for about every 4 parts we can fit 1 part gets a free ride.  That’s not bad!

In addition, we can machine 3 faces on each part.  Ordinarily, that would take 3 setups which would be a lot more time consuming.  Pretty cool, eh?  Depending on how much additional setup time is required for this arrangement versus just using the table, we’ve probably made our job more profitable.  Perhaps by quite a bit.

Suppose we had a tombstone that was a full 18″ long to match the Tormach’s travel.  Yes, we might need a big fixture plate so the 4th axis and tailstock have room on the table, but that’s doable.  With the same math, we’d get 4″ x 18″ x 4 sides = 288 square inches.  Dang, now we’ve got 68% more available area and we’re really starting to cook with fire.  68% more parts each time we press the green button get finished.

Suppose we create our own “Tombstone” with a piece of 1″ thick cast iron.  We can go 2″ if we want it to be more rigid.  Now, let’s further assume it is the width of the table’s diameter, which for the 8″ 4th axis is 7.9″.  We’ll mount it dead center of the axis, make it a full 18″ long, and use the two sides.  Our total area is now 7.9 inches x 18 inches x 2 sides = 284 square inches.  That’s almost as good as the earlier tombstone example, and gives us 66% more area.

What if we have a triangular tombstone that just fits in the inscribed circle of the table?  No problem.  The math says each of the 3 faces of the triangular tombstone will be 6.84 inches, so we have 6.84 x 18 x 3 = 369 sq inches.  That’s 116% more area than on our table–twice as many parts per run.  Winner, winner, chicken dinner!

When you look at it this way, it’s not hard to see how a 4th axis with tombstone can increase the available area for parts in each setup and make available more faces of the part to be machined.

For round parts, and for many things that go ’round, lathe tooling is where its at.  After all, it’s optimized to do workholding along a rotating axis.  Hence, it’s very common to mount lathe chucks on your 4th Axis:

All the same ideas that apply to which chuck to use in a lathe work for 4th Axes on mills.  Years ago, I put together a chart that has been useful to me in turning work and we can refer to it here too:

Can be time consuming to individually adjust the jaws, but will result in high precision. Can hold pieces offset for turning cams or eccentrics. Can hold irregular shapes and square or rectangular stock.

The modern alternative to turning between centers. Instead of using lathe dogs, which are kind of a nuisance to set up, the constant face system uses hydraulic or other force to grip and drive the spindle end. You can now buy these systems relatively cheaply on eBay (see seller 800Watt who sold me mine).

“Repeatability” applies to the ease with which you can remove a part and put it right back into the chuck in exactly the same position so you can continue machining.  It’s a big factor to consider, but typically isn’t as important for 4th Axis work as it is for turning.  When turning, for example, you often have to swap a part end for end, or you may have to take an existing part and put it in the lathe to rework some aspect.  With a 4th Axis, you will often just stick in a piece of raw material, in which case Repeatability is not a factor.  Hence the ubiquity of the relatively non-repeatable 3-jaw chuck for 4th Axis work.

Turning between centers happens fairly often with a 4th Axis just because you have to make sure you’re supporting any part with significant overhang out at the end too.  How much is significant?  I was taught 3 or 4 diameters was about a much as you want to hang off the chuck on a lathe before you start looking for more support.

Collets are really nice for turning work (hence the ubiquity of the old Hardinge Lathes and their 5C collet system).  They get high marks on just about every aspect.  It’s no coincidence that the original Haas 4th Axis had a 5C indexer:

Perhaps the biggest shortcoming of 5C collets is they only allow for parts of relatively limited diameter.  This can be overcome by turning things on their head.  Consider this setup:

I never would have guessed it, but Geof on CNCZone says the following 4-axis mill set up was able to machine these aluminum bars to length, ensure the faces were square, and drill and tap a hole faster than he could do it in a lathe.  You can imagine each of those 4 parts being a 5C spin indexer and suddenly you fit quite a few more parts on your 4th Axis.

I’ve written at more length on Stallion’s Trunnion fixtures in another post.  They’re very slick, but you need to make sure they solve the problem you need solved for your 4th Axis.  In particular, the access to the part is going to be limited to the access you can get form a vise.  As such, you’d be looking to use a Vise on your 4th Axis largely because it is super easy, familiar, and to gain access to 3 sides of the work rather than just the top in a single setup.

Workholding and Fixturing are always an art that it pays to learn well.  I’m always on the lookup for clever setups and fixtures and you should be too.  The 4th Axis opens whole new avenues for fixturing and setup.
