nikken rotary table free sample

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.

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.

You will receive an estimate of repair 5-10 days (depending on workload) after receiving rotary unit. Repairs take an average of 10 to 30 working days after receiving approval. Evaluation charge of $500.00 will apply if you do not get it done.

Your rotary unit is repaired, reassembled and run in for 10 hours. It is then re-inspected, all final adjustments and calibrations are performed to the original manufactures specification. We warranty our complete Rebuilds for 1 year.

As you can see we are the most qualified to tune-up or rebuild your rotary table. Having been there from the beginning, we know exactly what your table needs to bring it up to original specifications. Simply call Toll Free 1-800-342-3475 for any questions.

NIKKEN"s ‘Green Button Machining’ concept promotes the benefits of how NIKKEN solutions can ultimately contribute to increased machine uptime. Tool life can be fundamentally improved to negate ‘red button’ operation, with the machine being stopped for tool changeover or tool breakages and the consequential additional set-up times. Thus, reducing energy consumption, providing greater efficiency and a surge in sustainability.

A rotary table is a precision work positioning device used in metalworking. It enables the operator to drill or cut work at exact intervals around a fixed (usually horizontal or vertical) axis. Some rotary tables allow the use of index plates for indexing operations, and some can also be fitted with dividing plates that enable regular work positioning at divisions for which indexing plates are not available. A rotary fixture used in this fashion is more appropriately called a dividing head (indexing head).

The table shown is a manually operated type. Powered tables under the control of CNC machines are now available, and provide a fourth axis to CNC milling machines. Rotary tables are made with a solid base, which has provision for clamping onto another table or fixture. The actual table is a precision-machined disc to which the work piece is clamped (T slots are generally provided for this purpose). This disc can rotate freely, for indexing, or under the control of a worm (handwheel), with the worm wheel portion being made part of the actual table. High precision tables are driven by backlash compensating duplex worms.

The ratio between worm and table is generally 40:1, 72:1 or 90:1 but may be any ratio that can be easily divided exactly into 360°. This is for ease of use when indexing plates are available. A graduated dial and, often, a vernier scale enable the operator to position the table, and thus the work affixed to it with great accuracy.

Rotary tables are most commonly mounted "flat", with the table rotating around a vertical axis, in the same plane as the cutter of a vertical milling machine. An alternate setup is to mount the rotary table on its end (or mount it "flat" on a 90° angle plate), so that it rotates about a horizontal axis. In this configuration a tailstock can also be used, thus holding the workpiece "between centers."

With the table mounted on a secondary table, the workpiece is accurately centered on the rotary table"s axis, which in turn is centered on the cutting tool"s axis. All three axes are thus coaxial. From this point, the secondary table can be offset in either the X or Y direction to set the cutter the desired distance from the workpiece"s center. This allows concentric machining operations on the workpiece. Placing the workpiece eccentrically a set distance from the center permits more complex curves to be cut. As with other setups on a vertical mill, the milling operation can be either drilling a series of concentric, and possibly equidistant holes, or face or end milling either circular or semicircular shapes and contours.

with the addition of a compound table on top of the rotary table, the user can move the center of rotation to anywhere on the part being cut. This enables an arc to be cut at any place on the part.

Additionally, if converted to stepper motor operation, with a CNC milling machine and a tailstock, a rotary table allows many parts to be made on a mill that otherwise would require a lathe.

Rotary tables have many applications, including being used in the manufacture and inspection process of important elements in aerospace, automation and scientific industries. The use of rotary tables stretches as far as the film and animation industry, being used to obtain accuracy and precision in filming and photography.
