Taig CNC Micro Mills

CNC-Equipped “Overbuilt” Milling Machines

Taig CNC-Equipped Micro Mill 2018 Shortbed

The Taig Micro Mill is an “overbuilt” miniature milling machine. The liberal use of steel in its construction affords superior rigidity and the ability to work on hard metals. It is equipped with a 6-speed pulley system, which yields spindle speeds from 525–5,200 rpm on the manual machine, or 1,000–10,000 RPM on the CNC and CNC-ready models.

Fully CNC-equipped Mills have 200 oz. in stepper motors on the x, y, and z axes with integral high resolution encoders; Mach3 control software, and a sophisticated bi-level chopper driver capable of 30 inch per minute speeds in single-axis rapid traverse mode. There’s also a Mill with a Digital Servo Lock System (DSLS). CNC Mills include stepper motors, cables, and a controller box, but not a computer. You can use any Windows PC running XP or later. If the computer does not have a parallel port, be sure to specify the USB Adapter accessory as well. There are several more choices to make when configuring your mill. You need to decide whether you want ballscrews or the standard leadscrews, the Digital Servo Lock System versus the standard half-stepping CNC control, the ⅓ hp Variable Speed motor with DSPM versus the standard ¼ hp motor, and whether you want limit/home switches or not.

DSLS Option

This variation on the standard half-stepping controller is called the DSLS, for the Digital Servo Lock System controlling it. It uses optical encoders mounted on the stepper motors to keep track of their position as motion commands are executed, which allows the system to stop with a “limit switch” error if the position is off more than a certain small amount. This can save a valuable part from destruction should an unexpected error occur. We’ve been testing it, and have found that this system runs reliably given a feedrate of 50 inches per minute, about twice as fast as the standard system, which is useful for those who use the mill to cut plastics and other soft materials. It comes with the ER spindle and two collets, a relay box for software controlled spindle on-off (with M3/M5 commands) and another 110v accessory, such as a dust collector or mist coolant pump, you plug into the auxiliary 110v receptacle (using M8/M9).

This system also includes a license for Mach3, the popular CNC control software that runs in Windows and converts your parallel port-equipped computer into a dedicated CNC controller. Here’s some more information about it on the manufacturer’s site.

Shortbed and Longbed

The shortbed is 15.5″ long, with a travel of 9.5″ in the x axis. The longbed is 18.4″ long, with 12″ travel in x. The table size is 3.5″ × 15.5″ for the shortbed mills or 3.5″ × 18.5″ for the longbed mills. The longbed is particularly handy if you’re using Taig’s 4th axis attachment, which takes up some space on the bed. Most people think the extra x travel is worth the extra money, but if someone is very tight on space, or only works on very small projects, they might opt for the shorter bed.

Ballscrews Now Available

Ballscrews are nearly frictionless screws that rely on ball bearings recirculated by special nuts to provide motive force, rather than the pressure of screw threads against nut threads. One great advantage of them is that they eliminate backlash nearly altogether. Backlash is the gap in motion transmission that occurs when a standard screw changes direction, and pressure on one side of a thread becomes pressure on the other side. Since there always has to be some clearance between the threads of the nut driving the mill’s axis and those of the screw it turns on (or it couldn’t turn), there is always a point in any change of direction at which the screw is turning but the axis is not moving. This translates into a tiny error in the dimensions of the finished part, which the control software can try to compensate for but doesn’t always get exactly right.

For years, people tried to retrofit their Taig mills with ballscrews, hoping for faster rapids, smoother action, and much lower backlash. The right screws were difficult to obtain and required some precision machining to install correctly. Finally Taig decided to offer them pre-installed as a standard option. Running these precision-rolled 5 threads-per-inch screws and nuts puts less stress on the motors, so lost step errors become less likely, while accuracy is improved by eliminating backlash. The ball screw option is available on the 2019 longbed frame only; this model is called the 5019.

⅓ HP Variable Speed Motor (VSS with DSPM)

While the standard ¼ hp continuous-duty, totally enclosed fan-cooled (TEFC) motor works well, any changes of spindle speed must be done by stopping and changing the position of the belt on the pulley cluster. For those who want to be able to vary the spindle speed with a software "S" command in G-code, Taig/Microproto has recently come out with a new option: the ⅓ hp Variable Speed Spindle (VSS) motor with a Dual Symmetrical Pulley Multiplication (DSPM) transmission assembly. This affords slightly more speed on the high end (11,000 rpm) and plenty of torque on the low end, with wider belts than those used with the standard motor and pulley cluster. Unlike the standard configuration, this motor also mounts on-center, rather than off to the side. It comes with its own control box, which plugs into either the standard or DSLS controller. Taig calls this “VSS with DSPM.” It is offered on both the shortbed and longbed frames, and is compatible with any CNC mill configuration we offer.

Limit/Home Switches Option

Small, stepper-powered mills like these won’t destroy themselves like big servo-powered mills if they exceed the limits of travel; the motors won’t kill themselves by pushing against an immovable object. So limit switches haven’t been considered necessary on micro-mills like this, although they certainly don’t hurt, and can save you from losing position in a crash. But they also double as home switches, which are definitely handy to have, since they allow you to set a “home” position for all 3 axes to establish a machine-zero position without reference to the workpiece. You can save the offsets between the machine zero (home) position and the floating zeros that refer to the particular workpiece and restore them if position is lost.

Limit Switch on the XY Axis

Extended Y Axis

By using a longer screw and adding a spacer between the column and base, it is possible to add an extra inch of travel to the y axis, which can be critical for certain projects. The standard y axis travel is 5.5″; this modification extends that to 6.5″. It’s important to note, though, that using this extra travel will require affixing a plate to the mill bed (not supplied) that projects out over the front edge of the bed to support the workpiece, if it’s not capable of supporting itself during the milling process. This option is not available on shortbed mills based on the 2018. The option is slightly cheaper on mills with leadscrews.

USB Adapter

To run your CNC Taig on a computer that lacks a parallel port (as most modern PCs do) we suggest using a UC100 adapter, which allows it to connect via the USB port. This is required to run your CNC using a USB-equipped computers without a parallel port.

4th Axis Rotary Table and Adjustable Tailstock Option

The 4th axis rotary table accessory, used in a vertical orientation, adds a valuable functionality to the 3-axis Taig mill, enabling parts up to 4″ in diameter to be machined all the way around, or indexed to cut features in specific locations. Parts can be affixed directly to the face of its solid steel T-slotted table, or by using the included adapter, chucks can be screwed on to hold them. With a 72-tooth planetary gear run by a ball-bearing mounted worm gear, it has great torque and stability, and an angular resolution of .0125 degrees. It can also be locked in place if even more stability is required during a particular operation. An adjustable tailstock with dead center is included with the rotary table accessory for supporting the far end of a part, so that machining pressures don’t dislodge it.

Accessories

Taig has a good collection of accessories available for their mills. We sell these accessories only with the purchase of a mill. Some of the most popular accessories are available below once you choose the mill you wish to order. After selecting a mill, be sure to scroll down to the Accessories section at the bottom of the page.

The Milling Vise, shown in several photos on this site, and a 6-piece collet set are included standard with all Taig Mills.

1030 4-Jaw Chuck: This 3¼″ diameter all-steel chuck has 4 heat-treated reversable steel jaws that can move independently and are tightened with an Allen key, allowing square rectangular, octagonal, or round stock to be centered precisely and held firmly. Its internal ¾″-16 tpi threads match the rotary table adapter. If you’re only buying one chuck to use with the rotary table, this is the one we usually recommend. Note: these chucks are only used on certain lathes and the rotary table; their internal threads don’t match the 22mm–1.5mm threads of the ER spindle.

Taig 1030 4-Jaw Chuck Accessory (for rotary table)

1050 3-Jaw Scroll Chuck: This 3-jaw chuck can hold round and hexagonal stock. Its internal ¾″-16 tpi threads match the rotary table adapter. Unlike the 4 jaw chuck, the jaws on the 3-jaw chuck all move at the same time, allowing the user to load and unload parts very quickly, using the supplied “Tommy” bars. The soft aluminum jaws on this chuck can be easily machined for greater concentricity to the rotary table’s rotation, or to fixture special parts. Additional soft jaw sets (part 1151) can be purchased if needed. Note: these chucks are only used on certain lathes and the rotary table; their internal threads don’t match the 22mm–1.5mm threads of the ER spindle.

1060 4-Jaw Scroll Chuck: This 4-jaw chuck is good for holding square, round, or octagonal stock, and can quickly load and unload parts. Its internal ¾″-16 tpi threads match the rotary table adapter. It holds more firmly than the 3-jaw scroll chuck and its aluminum soft jaws can also be machined for greater concentricity or for fixturing special parts. Additional soft jaw sets (part 1161) can be purchased if needed. Note: these chucks are only used on certain lathes and the rotary table; their internal threads don’t match the 22mm–1.5mm threads of the ER spindle.

Jacobs Chucks: One of the most useful things the mill can do is to drill holes in specified locations. But most drill bits won’t fit in the supplied collets, which come in a limited range of sizes. To hold them, a Jacobs chuck is used. There are four choices in Jacobs Chucks. Along with each, we include an arbor that allows them to be held in the ⅜″ collet.

  • The 1090 “industrial quality” chuck which can hold drill bits from as small as they get up to ¼″ shank diameter.
  • The 1091 “commercial quality” chuck which can hold drill bits from as small as they get up to ¼″ shank diameter.
  • The 1092 “commercial quality” chuck which can hold drill bits from ⅛″ to ⅜″ shank diameter.
  • The 1093 “commercial quality” chuck which can hold drill bits from ⅛″ to ½″ shank diameter.

End Mills: End mills are the tools normally used to cut metal with a milling machine. There are lots of variations in these, but this is a good starter set consisting of five double-ended cutters with flat ends. Sizes are ¹⁄₁₆″   ³⁄₃₂″   ⅛″   ⁵⁄₃₂″   ³⁄₁₆″.

End Mills Set (sold together as a set)

Slitting Saw: Sometimes it’s necessary to make a cut in a piece of material that’s thinner and deeper than an endmill can be expected to accomplish. For this, a slitting saw is used. We sell a high-speed slitting saw along with an arbor that holds it in the ⅜″ collet.

Hi Speed Slitting Saw and Arbor

Fly Cutter: A piece of material may not be flat on top, or it might be desirable to mill the surface down more rapidly than can be done with end mills. For this, a fly cutter is used. It uses a ¼″ square-section cutter to sweep over the material, removing a wide swath at a time.

Fly Cutter (sold separately)

Spindle Wrenches: The ER collet system uses two opposing nuts that tighten the tapered and slitted collet into a tapered recess in the spindle, which compresses it around the tool. For this, two one-inch spindle wrenches are required. We sell this as a set of two wrenches.

Spindle Wrench (sold as a set of two)

Fixture Plate: While a vise is good for holding small parts, sometimes it’s necessary to attach larger ones to the mill bed for machining operations. With this fixture plate, and some 10-32 screws and washers, this is easy to do. This fixture plate is 4″ × 14″ × ⅝″ with holes on 1″ centers, and attaches to the bed of any Taig mill with 9 screws and T-nuts.

Fixture Plate (sold separately)

Edge Finder: When machining parts precisely, it’s helpful to know exactly where the edge of the workpiece is. Using this ¼″ shank edge finder, you can do that without damaging your tool or your part. Just touch off the side of the edge finder to the edge of your workpiece, subtract the .1″ radius of the tip, and you’ve got it.

Edge Finder (sold separately)

Boring Bar Head and Bars: Drilling holes larger than about ⅜″ can require expensive tooling and bog down the mill’s spindle. This boring bar holder, which comes with long and short boring bars, makes this possible for holes up to up to 1½″ diameter. Drill a ⅜″ pilot hole, then insert this tool into the ⅜″ collet and extend the bar incrementally until the hole is the desired size.

Boring Bar Head with Two Boring Bars (sold separately)
