The original Fadal rotary heads are still one of the best overall designed attachments for the Fadal machine. While there are many imported rotary heads that might "look good" on the outside, it"s the inside that really counts. The simple fact is the Fadal rotary tables were specifically designed to take a crash and keep on working.

Many different rotary heads were made throughout the years of production. A 4th or 5th rotary axis was one of the most popular machine options. In the early 90"s we started shipping all machines "4th axis ready" which means the machine has all the wiring necessary. You basically only needed an amplifier and a axis controller card with software. Contact us if you thinking of adding a 4th axis, we offer all the necessary components.

The very first rotary table sold that was sold on the VMC45 in 1981. It was designed and manufactured by Fadal for the VMC45, it never realized full production after production the VMC45 was stopped.

Troyke Mfg. Co. - Afterwards, with the introduction of the VMC40 in 1984, we began offering the TROYKE rotary products as a 4th axis option. The table had an interesting full contact bearing surface using Turcite between the faceplate and the casting with radial bearings support for the faceplate spindle. Few of these units still remain in the field today. If needed, we can provide complete service for these units.

Soon after 1987, we started adapting many of the popular Japanese rotary tables. Some customers would send us their tables and we adapt our motors and 4th axis interface to them. Eventually we started adding the Tsudakoma, Tecnara and Nikken rotary tables as a direct option to all machines.

VH65 - After years of installing and also repairing the many various manufactures rotary tables we sold, we learned what different designs worked and didn"t work in the machines. The second rotary head Fadal designed was the VH65. The VH65 stands for Vertical or Horizontal mount and 6.5" diameter faceplate.

TR65 - The TR65 (Tilt/Rotate, 6.5" dia. faceplate) had a unique clutch system build into the trunion for the B-axis. One of the biggest problems with 5-axis programming was that is was easier to crash than to program. And a B-axis crash usually resulted in the customer having to return the unit for repair. With this unique design, if the Z-axis crashed into the part, instead of damaging the gears it would simply slip the trunion clutch. The CNC knows the exact position of the B-axis because of the rotary scale feedback that is directly attached to the trunion and not the motor. The addition of the trunion clutch was so important because it virtually eliminated the disruption of operation for a service call.

C). Face plate spindle damage, we had one unit that actually collapsed part of the spindle shaft. Fortunately, we were able to repair the spindle, potentially saving the customer the cost of replacing the entire face plate spindle.

The largest B type model from Nikken with motor mounted to the rear, with higher gear ratio over earlier models increases speed over the vertically mounted motor version type CNC-400V. This unit also has a hydraulic clamping system. The unit has a 130mm spindle nose location with a location depth of 12mm with 105mm directly through the table and a has a centre height of 230mm in the vertical position. This device in the first instance is a vertical mount only device with options for a side mount motor, version which can be found under product code CNC-400V. An excellent carrying capacity of 250kg vertically unsupported and 500kg between centres with a standard tailstock with rotation speeds up to 22. 2rpm dependent on motor selection. (example given is with a 2000rpm motor)Net weight of this device is around 280kgThe Nikken CNC-401B rotary table is offered without motor and can be prepared to suit any interface at additional cost (see our interface listings for details and costs for “external interface”) (motor, switch, cable and connector requirements if you already have a “4th axis interface” in the machine) and machine interface costs (if you do not have the additional axis fitted). Motor is mounted to the rear via the right hand side on this device and is designed to avoid restriction to the Y axis capability and with a large bore available should you want to machine long bar components that need to be mounted through the centre. Please remember however, that being a back mount device the centre bore is restricted to passing through only the depth of the casting (240mm)This range of Nikken devices have Tungsten carbide worm shafts and hardened wheels which can mean less backlash adjustment required over a conventional brass/bronze standard gear.

A CNC machine is an electro-mechanical device used to manipulate and control machine-shop tools and devices using computer programming. In other words, controllers program the CNC machine to tell the machine shop tools what to do. The name CNC stands for computer numerical control.

The earliest CNC machines — or perhaps the forerunners of the CNC machine — were developed and used in the 1940s and ‘50s. These machines used a data storage technique known as punched tape. Of course, this technique soon became obsolete, and the systems quickly turned to analog and then digital computer processing methods.

The basic function of CNC machining is to take a blank piece of material, such as a block of plastic or a similar item, and transform it into a finished product. The CNC machine does this by telling the machine shop tool exactly how to move, and exactly what pieces of the material to cut away, to eventually arrive at the desired result.

Several of the technologies commonly used to actually create the finished products include drills, lathes, milling machines and other newer technologies like laser cutting machines, plasma cutting machines, water-jet cutting material, electron beam machining tools and many more. Materials that are commonly crafted with CNC machining include aluminum, steel, copper, titanium, wood, fiberglass, foam and plastic.

No matter how fast and efficient CNC machines is, they’re not infallible. They develop problems and need maintenance just like any other type of machine or tool. And like any other tool, there are certain things you can do that might inadvertently damage these machines. There are also definite steps you can take to keep them in good working order.

While there are certainly any number of problems that can lead to issues and errors within CNC machining, some problems are more commonplace than others. These problems are also ones that are easy to overlook and easy to misdiagnose.

CNC machines need to be carefully cleaned and lubricated on a regular basis — otherwise, problems can begin to arise. A lack of cleaning could lead to a buildup of dirt and debris. This might seem to be purely a hygiene issue, but it can have real implications in the machine’s output.

Another issue that could lead to serious problems in your CNC machining is incorrect programming. This is a simple cause-and-effect problem, since the programming directly controls the creation of the product. Therefore, if the programming is incorrect, the product will have problems.

To avoid this scenario, make sure every employee receives full and proper training on how to correctly code a CNC machine. This way, these kinds of easy-to-avoid mistakes will be less likely to happen, and you’ll be more likely to have a smooth and issue-free CNC machining process.

No matter how well you maintain your machines, how well you train your controllers or how carefully you care for your tools, CNC failures will still pop up. Some will be easy to solve, and some will be confusing, leaving you wondering what could possibly be wrong.

Solution: Although relay boards come in a variety of sizes and designs, they’re a common component of CNC machines. They all function in almost exactly the same way, so they’re easy to work with once you understand how they work.

Hopefully, by following these instructions, you’ll be able to better understand your CNC machines, which will help you become better equipped to clean, maintain and care for them. It will be easier for you to prevent problems from occurring, and you’ll know how to recognize a problem when it does occur.

Perhaps most importantly, however, we hope you’ll be able to diagnose the problems that will inevitably occur, and better able to troubleshoot a solution to these problems. Even if you encounter a problem that requires you to call on an outside resource for repairs, you’ll still be one step ahead. You’ll most likely already know what the problem is, where it’s occurring and have some idea of how it can be fixed.
