bridgeport rotary table manual pricelist

Bobs rolling table is, of course, the answer to horsing around a hefty rotary table or dividing head. (Somewhere in internet space there is a design for an elevating multiple shelf version which can successively bring any shelf to the top so that the heavy vice, rotab, dividing head or whatever on that shelf can be slid onto the mill. Gotta be the complete answer. Muggins here lost the bookmark and, so far hasn"t able to come up with a neat replication.)

In practical terms an 8" is generally too small for 12" to the foot work, especially once space lost to clamps is taken into account. Clamp losses are always vastly disproportionate to diameter for smaller tables. A 10" table has around half as much again useful; area as an 8" one whilst a 12" has nearly double. A 10" horizontal vertical is about the largest generally practical size to use vertically on a Bridgeport and tends not to be silly heavy. Its what I have and am well pleased with so possibly I"m biased.

Cost of course is an issue, especially if buying new or having shipped from a distant used dealer. An intermediate sub table is a good way of winning extra space. The 8" Vertex I have about the place will accommodate nearly 14" diameter and still permit the dial to be read, albeit with a bit of peering round the edge. Possibly a use for an old car or small truck flywheel. If the piggy bank will stand the strain the 1/2" solid aluminium breadboards sold by Thor Labs (Thorlabs, Inc. - Your Source for Fiber Optics, Laser Diodes, Optical Instrumentation and Polarization Measurement & Control) and not unaffordable. UK catalogue price for a 12" x 12" which will sit nicely on an 8" rotab is around £110, I imagine the $ price is pro rata. These are decently flat, although not perfect the 6 thou per square foot error quoted is very conservative in my experience, and have a grid of 1/4 UN tapped holes at 1" intervals which are a great help when mounting things and a great curse when de-swarfing! The anodised coating is tough too and well up to shop use.

Chrome Plated Ways -(Optional Feature)To maintain as far as possible the inherent accuracyand sensitivity of Bridgeport Millers, theexclusive feature of chrome plated ways is offered tousers of our machines.For a modest cost, Bridgeport can supply machineswhose ways are chrome plated at the points ofmaximum wear:• Back of Knee• Column Knee Gib• Top of Knee• Top of Saddle• Saddle Table GibChrome plate on these parts places a hard wearresistant surface on the paths of vertical, longitudinaland cross travel.A .002 deposit is made to assure ample wear life,an ideal lubricating surface and the lowest possibleco-efficient of friction. Hardness exceeds RockwellC-70. The chrome plate becomes an integral partof the base casting and does not set up anystresses or strains.To provide our customers, large or small with the mostversatile and flexible turret millers, Bridgeport hasdesigned and developed six working heads.These heads are supplied in a range of powers andcapabilities to handle most of the machining operationsrequired in any machine shop.All head models can be mounted on the front end of theram where they can be moved or swiveled to cover allplanes and angles in the spectrum.Models M, T and E can be mounted on the rearend of the ram and can beswung around to operate over the table.FEATURES COMMON TO ALL BRIDGEPORT HEADS• Self-contained, can be mounted on other machines.• Spindles are chrome nickel alloy, heat treatedand ground.• Spindle housings of high grade semi-steel castings.• Spindle bearings precision preloaded, accurately spacedfor maximum radial and thrust capacity.• Oil cup provides lubrication to all spindle bearings.• Dynamically balanced V belt pulleys proportioned forlong belt life, positive traction.• Simple adjustment of belt tension throughpivotally mounted motors.12

The world"s NO.1 Miller didn"t get its reputation by beingthrown together. It takes time to build a Bridgeport right,and we don"t build them any other way. Why?Because every part must be accurate to Bridgeport"sstandard. Every part must be inspected and many arehand fitted. Without this special care the Bridgeportwould be just another miller. A Bridgeport is worth itswait in time, money and performance.

Prerequisites: authorization on either [manual Bridgeport mill OR Clausing lathe] AND ShopBot CNC router. In other words you must be authorized on one manual cold metals manual machining center (lathe or mill) AND you must have been authorized on the operation of the ShopBot CNC router. You must be comfortable operating both of those prequalifying tools without supervision. The member to be authorized must be able to generate a toolpath in Fusion 360 with a simulated machining time of 2 minutes or less and must be able to provide a piece of stock and a single ended endmill 3/8" or smaller with a 3/8" shank that is appropriate for the toolpath.

Almost everything. The table and quill move as expected using the Heidenhain controller and joystick, including the handwheel. We can create and run simple programs using the Heidenhain conversational programming mode. We have switched the machine over to ISO G-code, and have been able to run programs with this. We have changed the communication parameters to FE mode, which permits transferring programs to/from the machine"s memory, as well as drip feeding programs directly.

The machine was wired at the factory for 460 volt 3 phase and we use 230 volt 3 phase in our shop. Ed and Dean rewired the motor and controller box, in a temporary fashion, to use 230v. It had been using a 460 to 230 volt transformer. Ryan removed this 6/26/2015 and changed all three transformers to use 230V, and re-enabled the accessory outlets at the rear of the machine. He also moved the Heidenhain power source back to the Bridgeport control. PS:One has voltage approaching 250V, so in some cases the voltages at transformer taps are a bit high. However the Heidenhain power, and the external 120V outlets, appear pretty much spot on.

Y axis ball screw cover is bent and not sliding properly. It should be removed and replaced (or bent straight). Removal is difficult because it is bent. This could require removing the table, which is heavy.

The homing sequence could not complete due to a bad index signal from the y axis rotary encoder. By adjusting the alignment of the encoder to the motor, the signal appeared. This adjustment may need attention in the future.

Because the Interact Series 1 uses tool holders, not collets, you are supposed to mount each tool in its own holder (which hopefully fixes its length relative to the spindle). You mount your longest tool, touch off the workpiece, call that point Z=0, and designate its tool offset as 0. Then you mount each tool in turn, touch off the workpiece, and store the different Z value (which will be negative) as the tool offset of each other tool. You can define tool offsets in G-code, but Aspire doesn"t seem to have that concept. Ryan changed machine parameter 225 to define 25 slots in a central tool table. This is a special Program 0, where you manually key in all your tool offsets and radius values (but that generally isn"t used for CAM-generated G-code.) So if T=1 is my zero tool, a cut to Z-0.5 will move the spindle to Z-0.5 and cut a half inch into the workpiece. But if I change to tool T=2 which has a L-1.0 offset, a cut in G-code to Z-0.5 will move the spindle to T-1.5, but since the tool is 1 inch shorter, it will cut a half inch into the workpiece. But it is critical now to check the global tool table before running a job!
