To me, this table is just the right size and weight, not so small as to be a mere toy, but not too large, heavy, and expensive for my simple needs. I have had it for three weeks now and decided to review it after completing my first project.

When I first examined it I noticed that is seemed very well made and operated very smoothly. It definitely exceeded my expectations. I noticed it had a backlash of 20 minutes of arc, which I considered this totally acceptable. Accurate work is always done by turning knobs in one direction only. This table has a convenient knob to hold the position when it is reached. You can set the angle to about 1 minute of arc, and hold it there.

For my first project I made a couple of simple fixtures. One was a centering hold down, the other was an aluminum sub base. This is especially useful for mounting the table vertically in my drill press cross vise.

This post shows what I did to add a stepper motor indexed drive to an EMCO 150mm Rotary table, and how I added a "Grip-True" style adjustment to the attachable 125mm 3-Jaw and 5C chucks.

I decided to follow MichaelG"s route of using a rotary table as the gear blank active axis, and began modifying my rotary table. The main reason for the test bed requirement is that it is very difficult to test the software in simulation as far as accelerations are concerned.

This is an issue when doing continuous hobbing, as the blank has to spin up synchronised to the hob, when starting and stopping the hob spindle. If the inertial mass and friction exceeds the steppers capability, steps are lost and sync as well, with gear teeth misaligned. Some electronic hobbers have very little blank holder inertial mass to spin, while using a rotary table is probably the most mass you could apply..

The Worm stub external to the table is short and of not a very practical shape to attach the stepper - I decide to go for belt drive as even with a NEMA23 stepper, if the stepper shaft were aligned with the worm drive, the stepper body would protrude about 16mm below the underside of the table"s base.

That makes it difficult when placing the table on the bench, mill table, etc - spacers are needed and so on. I made an adaptor for the pulley, which includes a shaft preload to remove worm shaft end-play.

I"m considering getting a rotary table for my V10 Maximat. I"ve seen the array of stuff on eBay and from the various suppliers. I don"t feel much like paying the asking price for an original Emco, which is only 4" anyway.

As to the milling base: The same friend has an Emco-Maier tabletop milling machine (I forget the model designation), which has the same head and column as on my V10, but has a much longer/deeper table than is possible on the V10. He showed me some old literature (from American Edelstaal) that listed the base unit as an accessory, allowing you to convert the V10 (or I suppose the V7) to two machines.

I don"t have your experience or expertise to modify/re-machine the "Out of the East" stuff, so I don"t think I"ll try to make one of the Chinese-junk tables work.

I"ll keep looking for an original (or maybe East-European, they"re still good) rotary table. I may have to budget kind of tight for a few months, but good tools are worth it.

My main interest in the rotary table was originally making gears... which I since found out is a messy business - and with some research, usually unnecessary. But the idea of being able to mill an O-ring groove (or a carburetor spacer) is very appealing.

I found out recently that Emco used to sell the base only, so you could remove the milling column and have it transported it this larger, more stable base.

Wouldn"t 4" be kind of small for any real work, though? (Keeping in mind that the Emco mill, with only 1/3 hp, really isn"t a "production" tool, it still would be more useful to hold a bigger workpiece.)

Adding a larger table would be a solution but then the clearance distance to the spindle would be so reduced specially if a chuck is being used, that will render the milling head almost useless.

Primarily purchased for the production of large-scale frames, layup tools, bond tools, and general tooling components for customers in the aerospace and automotive sectors, the new 5-axis MECOF was installed and commissioned in December 2016. The new horizontal milling machine is the epitome of flexibility with its ability to work in both the horizontal and vertical axes with its 3+2 axis configuration that combines with a rotary table that takes the new acquisition to a 7-axis variant that allows Baker Industries to flexibly machine five sides of the workpiece in a single set-up.

The remarkably large capacity of the EcoMill machine is highlighted by the ability to either machine jobs on the extremely spacious 10-meter travel. This unique design enables Baker Industries to process parts up to a maximum weight of 44,000 lbs. on the rotary table or a colossal 33,000 lbs./sq. ft. if parts are machined on the stationary table. In addition to the 10-meter X-axis, the EcoMill offers travel of 1300 mm in the Y-axis and 2.5 m in the Z-axis. To maximize productivity, the new EcoMill speeds around the work area with rapid travel and feed rates of 30 m/min.

Alluding to why the 233 employee company has invested in one of the first next-generation EcoMill machines in the state, EMCO Mecof Chief Executive Officer, Dr. Ing. Stefan Hansch says: “Baker Industries is undoubtedly a market leader in its industry sector and the investment in the next generation EcoMill highlights the company’s ambition to invest in technology. The new EcoMill is one of the most powerful and flexible machine tools in its category and Baker Industries has realized the potential of the EcoMill to deliver improved productivity, efficiency, flexibility, and machining capability. The EcoMill installed at Baker Industries is an extremely robust package that is crammed with proven technology that includes the latest tool probing and gauging technology, a powerful Heidenhain CNC control system, and an extremely efficient chip extraction system. The EcoMill has been well received by the automotive and aerospace industries and we are excited to be working with such a prestigious manufacturer that works across both market segments.”

Emco Maximat FB-2 Indexing Rotary Table with CNC Control NEMA 23 Stepper Motor. I picked this up recently with an Emco Maximat lathe. Contraindications: This is not an Emco production item so there are no instructions. Currently the rotary table has a Microkinetics 175 ounce NEMA 23 stepper motor. Best Store Search Return Policy Shipping Notes Questions Offers Revised 04/19/15 Description: Extremely versatile Emco Rotary Table with stepper motor positioning added. I picked this up recently with an Emco Maximat lathe. This rotary table has been substantially modified. Currently the rotary table has a Microkinetics 175 ounce NEMA 23 stepper motor. This could easily be changed to a more powerful NEMA 23 motor. The stepper motor transmission is geared 64:1 with substantial holding power as listed here. The transmission uses 80MXL timing belts. I noticed these aren"t Kevlar belts and would suggest the upgrade, as Kevlar belts are stronger. This is an important consideration when adjusting the tension screws for both timing belts. The higher the tension on the belts the greater the precision and rigidity (until the belts break of course!). As it is with the existing belts, there is no free play in the table per se but about 1/3 +/- degree of backlash from the belts only noticeable as expected on changes of direction. I believe this would be reduced by Kevlar belts. A table tension system using spring washers was added to maintain rigidity using the old rotary table lock down screws. Also a grease port was added for heavy rotary table use. The item is currently full of grease. Does not include hold down hardware. You will have to make or acquire these items to properly use this accessory. Contraindications: This is not an Emco production item so there are no instructions. If you are not mechanically adept you will be confounded by the nature of the rotary table setup and will never be able to get it reassembled and working properly after a simple timing belt change. Alcoholic beverage consumption and barbituate use may also complicate the setup and use of the accessory. Condition: I fired it up using my CNC system and it turns smoothly in both directions. The table surface is excellent and looks reground; there are some minor cosmetic marks on it from light use that show plainly in the photos. Overall e xcellent operating and cosmetic condition. There are some minor flaws in the painted plates and there are some oil and oxidation stains a s can be expected from age on the bare metal surfaces. I didn"t actually use this rotary table to produce parts but my guess would be that if you take reasonably sized cuts on each pass you will realize outstanding results exactly as configured here. This would be a superb accessory for cutting gears or threading operations. Shipping: Charges shown are flat rate to the Continental US, Canada, Mexico, Australia, New Zealand and EU ONLY.

The 7 was very similar in general layout and specification to the V10 but of 3.5" (90 mm) centre height and 17.5" (450 mm) between centres - although a 24.6" capacity (600 mm) longer bed model, the 7L, was also offered. Two very useful feature of this lathe were the excellent spread of speeds--65 to 2800 r.p.m for the English market- and the ease of changing them; there were no belts to move only two headstock-mounted levers and the 2-speed electric motor push buttons. No screwcutting gearbox was offered and the standard changewheel set consisted of 9 gears which could cut metric threads from 0.4 mm to 3 mm, English Threads from 8 to 80 t.p.i. and module from 0.2 to 1.Continued:Emco Maximat V10Pwith screwcutting gearbox, power cross feed and early 4-speed milling head. Although these heads are shown in the maker"s literature canted over to run on their side it is wise to ensure that, if they are tilted over so far, they are not overfilled with oil. If they are the simple oil thrower will not stop lubricant leaking into the electric motor.Continued:Shared between the models, the headstock appears to have been internally identical, with an arrangement such that the drive was always taken through a pair of gears where one in metal engaged with another whose steel hub carried laminated "fibre" teeth. Combined with lubrication by oil-splash this combination gave unusually quiet running - and a reputation for reliability. However, none of the assemblies can take foolish handling, and trying to move the selector levers before the shafts have completely stopped leads to the main-spindle fibre gear being eaten away on one side and the eventual failure of the two lightly-constructed alloy selector forks - and it is not unknown for these to also fail with age and fatigue. Hence, it"s a good idea (and especially before buying one of these lathes) to remove the four screws securing the headstock cover plate and take a good look inside. Cracks in the selectors are hard to see, but a magnifying glass will often reveal them. If the a fork does break, and drop into the headstock, it will wreck two or more pairs of gears. New forks, in bronze, are available - though as they are made in batches might not always be in stock (email for details).

A 0.25 h.p. 4-speed, 350, 640, 780 and 1450 r.p.m. milling head (later replaced with a six speed), proved to be a popular, if expensive, fitting and was lifted straight from the contemporary Emco bench milling machine. The head"s mounting column was held in a simple cast-iron bracket bolted to the back of the bed by four set-screws and arranged so that it rested on the bench exactly level with the bed feet. Electrical control of the head was integrated into that used for the lathe, with the necessary switchgear built as standard into every machine to allow easy retrofitting. The head had a 40 mm stroke quill, carried a No. 2 Morse taper, and offered 305 mm of clearance between spindle nose and table and some 145 mm of throat.

One point to consider on all Emco lathes of this era is the small frame size of the electric motors and their tendency to run very hot. However, being of modern design, they should, in theory, be no more unreliable than older types of more generous proportions, but with less effective insulation - however, one has to say, their reputation in this respect is not good and direct replacements appear unavailable.

A wide range of (expensive) extras was available for the V10 and V10P including steadies, collets, rotary tables and a neat toolpost grinder that used the special high-speed collet-holding headstock spindle assembly supplied as an option for the Unimat SL1000Tony Griffiths
