ag davis rotary table for sale

The ULTRARON is a precision-engineered rotary table, produced entirely at A.G. Davis - AA Gage, with applications for inspection, tool room and/or production machining. The ULTRARON"s accuracy is made possible by the use of precision lapped balls and integral ground races. The ULTRARON has a standard concentricity accuracy of 30 millionths T.I.R. (0.000030) and a wobble or rotating parallelism is held within 100 millionths (0.0001) on sizes to 24" in diameter.

The A.G. Davis - AA Gage Precision Broach Rotary Tables are high precision rotary systems manufactured for precision broaching applications. The Broach Rotary Tables can be supplied with stand-alone or rack-mounted controller, or can be interfaced to your operational Rotary Axis Control.

A. G. Davis - AA Gage has been the industry leader in providing the design and manufacture for precision gages of all types, from small attribute (go/no go) gages, variable (data) gages, standard gages and components, to transfer line, gantry loaded semi-automatic and fully automatic inspection machines.

The Precision Rotary Tables are designed for use in Metrology, Inspection, and other precision applications. The Rotary Tables can be supplied with stand-alone or rack-mounted controllers, or can be interfaced to your operational Rotary Axis Control. The control is a solid-state, closed-loop system incorporating the latest State-of-the-Art concepts and can include IEEE or RS232 interface for remote program control.

The Air Float Rotary Table consists of hardened steel faceplate, which is floated on air in the thrust plane and centered by preload ball bearings radially during rotation. After an index move is completed the Air float is shut off allowing the faceplate to rest on the base of the rotary table producing excellent wobble characteristics. This action also friction locks the Air Float Rotary Table. A high-grade meehanite base casting is used to support the faceplate. Standard faceplate mounting pattern is by threaded hole patterns with other configurations available. The Air Float Type Precision Rotary Table can only be used with the faceplate in the horizontal plane.

The Ball Bearing Rotary Table consists of hardened steel faceplate supported by a maximum diameter preloaded angular contact ball bearing. The large diameter ball bearing produces excellent wobble characteristics. The preloaded ball bearing along with the closed loop servo system provides for continuous as well as point-to-point measuring. A high-grade meehanite base casting is used to support the ball bearing. Standard faceplate mounting pattern is by threaded hole patterns with other configurations available.

The Air Bearing Rotary Table consists of hardened and stabilized stainless steels and/or high-grade steels with corrosion resistant coatings. The base is made from high-grade meehanite castings. The Rotary Table employs a fully trapped gas bearing for both radial and thrust planes. The gas bearing jets are manufactured of precision machined gemstones. The air bearing along with the closed loop servo system provides for continuous as well as point to point measuring. Standard faceplate piece part hold down consists of threaded hole patterns, or special configurations are optionally available.

Air bearings require small clearances between rotating members. The possibility of these surfaces contacting each other during rotation is a major concern of air bearing users. Typically when this touch down does occur conventional air bearings will seize up and require major repairs. A.G. Davis-AA Gage has eliminated this possibility. The air orifice manifold detail is constructed from hardened stainless steel. The opposing surfaces are constructed from high-grade hardened steel and coated with a proprietary material. This construction permits the air bearing to lose air pressure while rotating even under maximum rated load and not damage the air bearing thrust and radial precision surfaces. After the air pressure is reinstated the bearing will freely operate as before.

The servo drive utilizes a capstan type friction wheel drive system. This drive system eliminates backlash (lost motion) between the servo motor and the Rotary Table it must position. The zero backlash condition provides an excellent foundation for a servo system which positions accurately without instability over a wide range of payload conditions.

The drive is constructed to eliminate any side loading of the rotary table bearings. Tangential loading only. This is accomplished by mounting the entire capstan drive package on a pivot which is tangent to the table drive rim. The main capstan drives on the O.D. of the drive rim while an opposing wheel bearing runs on the I.D. of the drive rim. The drive force required to engage the main capstan is provided by the opposing wheel bearing which creates a pinching action on the drive rim. This pinching action along with the pivot allow the drive to follow the drive rim"s motion without imparting any force to the rotary tables precision bearings. Note -unwanted side loading of the rotary table bearing will cause an increase

The base of the rotary table can be provided with air jet pads. These pads when actuated allow the rotary table to float on a level continuous flat surface. This feature is particularly convenient to CMM users who often move the rotary table to other locations on the CMM for various applications. The Air Ride is actuated by a dead man switch (automatically turns off when released). The switch is located adjacent to the drive cover.

A micro switch can be provided to close approximately 10° to 15° before the encoder"s marker pulse. The approach direction can be either clockwise or counterclockwise. Specify the desired approach direction when ordering. The encoder marker pulse will be located within 5° of the rotary tables zero position (the RT outline drawing shows the rotary table at it"s zero position).

A switch (DISENGAGE/ENGAGE DRIVE) can be provided adjacent to the drive cover. This toggle switch actuates a cylinder that alternately disengages and/or engages the drive. This switch also turns the Air Float Bearing on and off. This permits freewheel rotation of the face plate for faster centering and complete manual operation.

We were selling the precision index table called "Ultradex®" and manufactured by AA Gage in Japan. Last year we were talking about this "Ultradex®" with an engineer of a customer and have fixed the specification after several discussions per E-mail. Then we were asked about this inquiry by the purchase department whether we are the sole agent or not. We had some experiences to sell "Ultradex®" to Japanese customers, however we have not yet discussed about this distribution issue with Manager of Firm A.G. Davis - AA Gage, after AA Gage joined with A. G. Davis. We answered the customer that we are not a sole agent but we can directly buy "Ultradex®" and do the after sales service in Japan. However the customer bought it through a Japanese company in the States, then the manufacturer had to sell it to him. It is unfair, because we have decided the specification after discussion with the customer�fs engineer. The Japanese company knew only the Type Number of the "ULTRADEX®" and he could buy it and sell it with his lowest commission. We are not big, so we cannot take the responsibility to be a sole agent in Japan. But the manufacturer wrote for us the Certificate of the Sales Representative in Japan. We can of course sell all products of Firm A.G. Davis - AA Gage, and we will do our best with our good faith to the customer who contacts with us as in the past. Please watch and ask us with warm look, thank you.

It is the must that contractor must use the same measuring instruments used in the original contractor for the inspection in the Aviation Industry. This time we were given the part drawing with conditions using an A.G. Davis Groove Gage and a Federal Indicator. But this order is the 2nd time for the customer, so he asked us also some modifications that were proposed by a field operator. We sent the drawing and requirements to Firm A.G. Davis - AA Gage and got the quotation. At last we could place an order of a Groove Gage with Federal Indicator and with customer"s modifications.

A trading company asked us whether we can import the A.G. Davis Groove Gage, after he saw our web site. According to him the end use uses the Groove Gage as the photo of the right side, and the gage was engraved the name of A.G. Davis on it. The end user wanted to change the dimension. We were importing the "Ultradex®" of AA Gage, however we had not yet contacted with Firm A.G. Davis - AA Gage, after AA Gage joined with A.G. Davis. And we begun to contact with Firm A.G. Davis - AA Gage, we could place an order after several E-mai exchanges, and we could deliver the Groove Gage without a problem. After this in the future we were recognized to import the goods from Firm A.G. Davis - AA Gage directly.

Basically with our current probes we can"t measure the rotary sphere at any rotation greater than 180°. We have a star probe, and I might be able to get it to work with that, but I haven"t bothered with it.

Weed control in vineyards enhances the establishment of newly planted vines and improves the growth and yield of established vines. Growers have many weed management tools available to achieve these objectives, but the method in which these tools are utilized vary from year to year and from vineyard to vineyard.

Weed management is an integral part of an overall vineyard management system. Plants on the vineyard floor influence the presence of other pests such as vertebrates, insects, mites, nematodes, and diseases. A weed management program should start before new vines are planted. The more difficult-to-control weeds (particularly perennials) are easier to manage before vines are planted. Weeds reduce vine growth and yield by competing for water, nutrients, and sunlight. Competition from weeds is most severe during the first few years after planting in areas where vine root growth is limited due to shallow or compacted soil. Weeds growing around the trunk compete directly with vine growth and provide a good habitat for field mice or voles, which can girdle and kill young vines. Gophers are most often found in nontilled vineyards and are common where broadleaf weeds, such as field bindweed and perennial clovers, predominate. These subterranean animals feed on the roots and can weaken or kill young vines. Additionally, weeds that have dried out can become a serious fire hazard

Integrated weed management practices vary considerably from vineyard to vineyard. Location in the state, climatic conditions, soils, weed species present, age of vines, irrigation practices, topography, and grower preferences significantly influence vineyard floor management decisions and the techniques and tools used.

Soil characteristics play an important role in weed management. Soil texture and organic matter influence the composition of weed species present, the number and timing of cultivations required, and the activity and residual effects of herbicides applied. Sandy loam soils usually dry more quickly than clay soils and may require more frequent cultivation to achieve effective weed control. On light-textured soils, annual species, such as puncturevine, crabgrass, horseweed, and Panicum spp., and perennial weeds, such as johnsongrass, nutsedge, and bermudagrass, are more prevalent. On heavier-textured soils, perennials such as curly dock, field bindweed, and dallisgrass are commonly found. Many herbicide labels recommend using low rates of the product on soils considered high in sand or low in organic matter, in order to reduce the potential for vine injury as herbicides can move deeper in the profile. A second, or split application, may be necessary.

Herbicides are traditionally discussed as belonging to two groups: those that are active against germinating weed seeds (preemergence herbicides) and those active on growing plants (postemergence herbicides). Some herbicides have pre- and postemergence activity. Herbicides vary in their ability to control different weed species. In most vineyards, herbicides are only used on a narrow strip centered on the vineyard row that comprises 15 to 30% of the total vineyard area. Check the SUSCEPTIBILITY OF WEEDS TO HERBICIDE CONTROL tables and consult product labels for specific weed control activity.

Preemergence herbicides are active in the soil against germinating weed seedlings. These herbicides are applied to bare soil and then moved into the soil with rain or irrigation where they affect germinating weed seeds. However, some herbicides like trifluralin, require mechanical incorporation. If herbicides remain on the soil surface without being activated within a reasonable amount of time through rain, irrigation, or mechanical incorporation, some will degrade rapidly from exposure to sunlight, resulting in reduced weed control. Large weed seeds, such as wild oat, may germinate in the soil below the herbicide zone and will not be controlled by a treatment.

Application equipment must be accurately calibrated to apply the proper amount of carrier and herbicide to the soil and young growing weeds. For safe application and to minimize drift, spray equipment should be equipped with a short boom that has nozzles designed to minimize the amount of very small spray particles generated. Avoid spray nozzles and spray pressures that produce spray droplets less than 200 microns in size (very fine and fine-sized droplets) as these tend to drift more. Nozzle technology has advanced significantly in recent years and all major nozzle manufacturers have developed one or more nozzles that will minimize drift. Check your nozzle catalog or the internet. Off center (OC) nozzles are often used alone or on the end of the boom to direct herbicide applications toward the center of the row. Some herbicides require special use precautions as indicated in the table below. Always read and follow the entire product label before using any pesticide.
