I was once thinking 2 standard transmission flywheels would make a fixture that you are needing. the bottom fly wheel would be surface side down with no ring gear for a bolt down flange. The top flywheel would be face up with a seriese of tapped hole for hold down capabilitys. Im still pondering on the bearing between the 2. The ring gear on the upper flywheel can be mated with a crank handle to provide rotation.

For a corner fillet weld such as those, it may help if you grind off half of each corner on the slotted plates giving a 45 deg V. This will help to ensure the weld gets good penetration and strength at the same time as allowing you to retain the original edges for alignment.

Looks to me like you are using a 240V single phase welder. In Oz I would use a Satin craft 13 electrode as these have a slower flux than a Satin craft 12. This helps stop the flux from running into the weld pool and stopping the arc. My welder has only 2 settings 2.5 and 3.2 mm so I try and use the shortest possible cable between the power point and the welder. If I have to go longer a heavier duty cable helps keep up the volts and amps.

As CNC machine tool technology has evolved it’s possible to do more operations better, faster and at lower cost than ever before. These advances also mean that there are more machine components and accessories to monitor and maintain. Often overlooked are rotary or trunnion tables that reduce setup and cycle times and, in many applications, enable the machining of complex parts.

Properly functioning rotaries and trunnions are essential to making accurate parts, and like other critical machine components should be checked regularly for signs of wear or damage. The most obvious tipoff that something is wrong with the rotary device is that you experience difficulty setting up a part, or begin producing out-of-tolerance parts. However there are 3 simple checks that, if done regularly, can help keep your rotary tables and trunnions in peak working order:

Check the oil sight glass for discolored or cloudy conditions. This may indicate that a seal has failed and coolant, dirt or other debris is in the lubrication system. Contaminated oil cannot properly protect the inner workings of the rotary device and can cause thousands of dollars in damage.

Inspect cables to make sure they aren’t broken or becoming soft and worn. A short in the electrical circuits caused by faulty cables can seriously damage electrical components.

Keep the control unit clean and free of moisture, oil and dirt. All electronic controls are subject to failure if the circuit boards are compromised. This is especially true in hot, humid conditions or when there is substantial oil residue in the air.

Many rotary table manufacturers outsource gear fabrication to lower costs. While that strategy may offer short term cost savings, Index Design’s American made rotary tables are built with gears cut in house. This is the only way to closely monitor and control tolerances, consistency and performance.

Our rotary tables incorporate large diameter high tensile bronze worm gears mated against hardened steel drive shafts. The combination of metal gives superior wear properties for long lasting operation. As the rotary table is run, the properties of a tin bronze gear develops a low friction deposit on the mating steel drive shaft. These deposits fill in microscopic pores of the mating surface. Over time, as these deposits are embedded on the surface, wear decreases followed by a reduction in frictional forces within the gear assembly.

Final inspection and verification of specification performance is done with precision calibration equipment capable of measure tolerances of +/- 1 arc second in any position. Any deviations from specified angular positions are corrected so our customers can be assured that they are receiving the performance we guarantee.

In addition, the data gathered from our automated calibration procedure allow our engineers to assess, monitor and improve the static and dynamic performance of prototype rotary tables during the design phase.

Our engineers have a long and rich history in the machine tool business, they combine decades of both CNC machine tool and rotary table manufacturing experience with the latest design tools to produce rotary tables with superior performance and dependability.

Our CAD/CAM software is used to analyze displacement and stress for each component, sub-assembly and total assembly. However, the best software and technology is worth next to nothing if no one understands the craftsmanship. This is particularly true when manufacturing precision rotary tables which involves many steps. Despite all the modernization and automation available, a large part of the manufacturing process is still completed by hand. At Index Designs, we understand and appreciate craftsmanship, It is designed and built into our products.

For starters, we need to know what a rotary table is. Rotary table is a high precision positioning device which is widely used in machining and metalworking. With the rotation, the operators can perform drilling, milling, cutting and other applications at exact intervals around the horizontal or vertical axis. To achieve the high accuracy and efficiency, many rotary tables can incorporate with index plates or dividing plates. With the help of additional components, the rotary tables can be used for indexing application or even position the work piece at divisions on the dividing plates.

When it comes to powered rotary table, it is the rotary tables widely used in CNC machining center which responsible for precisely locating the parts in the commanded angle in order to perform multi-face machining at one time. Originally, in a 3-axis CNC machining center, there are only X, Y, Z working axes. The X, Y, Z axis are the linear lathe axes. Operating along the XYZ planes, the Z axis is the important axis that is aligned with the main axis of the machines. On the same plane, the Y axis works in horizontal direction while the X axis is the vertical operation direction.

In typical machining centers that have the 4th axis, the 4th axis is the 180° rotation axis around the X axis. With a CNC motors, the motorized rotary tables can play the role as the 4th axis in the machining centers to enhance the flexibility of metalworking applications. The arrangement of involving powered rotary table in 3-axis machining center is popular for cam machining, helical grooves producing, blade machining and other unique profile machining. Powered rotary tables have a wide range of applications, for example, utilizing in both manufacturing and inspection stage of essential components in aerospace industry, automobile manufacturing and other scientific industries.

The vital elements of a powered rotary table include a supporting disc where the work pieces are clamped for machining, a solid base for clamping onto another larger table, machine, or machining center, the CNC controller and motor. A through hole is machined into the CNC rotary table to fit the Morse taper center or fixture.

The precision-machined disc is the rotating surface where the work piece is positioned and fixed firmly. T slots are the typical parts to help clamping the work pieces. The chuck is used to hold the work piece with a dial indicator to ensure the chuck and product are centered. After installing the chuck with bolts and T-nuts then checking if the work piece is centered, the operator can position the job on the table. The disc can spin freely under the instructions from CNC controller and motor. It is also the components which the indexing plate or dividing plate can mount with. When CNC controller and the CNC motor provide inputs, the rotation of the worm gear is activated and the mating gear mounted beneath the table surface begins to spin, either. The worm gears perform the precise rotations of the rotary table and every parts of the disc are critically calibrated in degrees.

The computer numerical controller transport programmed commands to activate the powered rotary tables. The commands are conveyed in CAD files, which refers to Computer Aided Design files, and provide sequential instructions to ensure the smooth operation. Eliminating the human power, CNC provides reliable and precise high performance positioning for further machining applications.

The size and type of the CNC motors can determine the routers precision, the efficiency and also the accuracy. Following is the basic introduction of two classes of motors used in CNC rotary tables, which are the stepper motors and the servo motors. Within these 2 classes, there are more subtypes.

Servo motors use closed looping variable circuit which continuously run for maintaining smooth motor function. The brushes on this type of CNC motors should be replaced after two thousand hours of operation. The encoders may need to be checked and replaced, too. Servo motors feature the efficiency in power consumption. They perform with about 90 percent of efficiency when giving light loads.

Stepper motors only require the wires that connected with the motor driver, having simpler setup. The only wearing part in this type of CNC motors is the bearing mounted on the motor, which slightly reduce the equipment life. Compared to servo type, stepper motors consume a large amount of power to provide the output, and much of them is converted to heat. Depending on the stepper driver, the stepper motors are often seventy percent efficient.
