Granite 3-in-1: America’s Bench Top Machine Shop Workhorse
From production shop to home shop – the Granite 3-in-1 machine is a tough, reliable workhorse that puts a real machine shop on your bench top.
Machine
Quality, precision, and reliability are built into this tough bench top workhorse. Americas’s #1 premium bench top machine tool - for over 25 years.
- PRECISION: matches higher priced industrial grade machines.
- BALANCE: easy transition from different applications.
- FEATURES: professional level automation speeds your work.
- MASS: heavy casting providing damping and increased precision.
- RELIABILITY: designed and built for a lifetime of productivity.
As Close As You’ll Get to American Made
1) US Developed and Designed: The Granite Machine was designed by our engineers in Ann Arbor, Michigan based on machine user requests.
2) Precision is far higher than other 3-in-1 knock-offs: All components are machineed to tighter specs, bearings are much higher grade, and the basic design is initially higher precision.
3) Higher Quality Production: Detroit Machine Tool employees oversee the production and quality control process at our sister factory of more than 25 years. No other seller can make that claim.
4) Superior Features: No machine out there can match the speed and accuracy with which you can accomplish your machining tasks on a Granite machine.
Other 3-in-1 combo tools on the market are NOT EVEN in the same category for quality as the Smithy line of machine tools.
Five Reasons - Why Granite is the Best
Watch this video and learn about the American design, quality construction, and balanced features of the Granite 3-in-1 Lathe.Mill.Drill. The original bench-top combo machine tool and still the best. Designed and built for American machinists and craftsmen.
OWNERS SPEAK OUT
Comments from Successful Smithy Owners
“I can make or fix almost anything on my Smithy: tooling, repair equipment, prototypes, and turkey and other game calls. I looked at several single-operation machines but I liked Smithy’s looks, specs, and the way it is constructed and functions. I needed Smithy quality at an affordable price. Best reasons to own a Smithy? Price, construction, versatility, quality, looks, and ease of operation.” - Edward T. PA
GUARANTEED TO PAY ITS OWN WAY
Granite Owners Make Money - And Save Money Too
“I own a business manufacturing aftermarket snowmobile and ATV parts and accessories. I use my Smithy for small production runs. It has paid for itself approximately 3 to 4 times over at this point.” - Ernest N.

Machine/Model Comparisons

I see two combo machine designs out there on the market. One is the "mill head mounted on the lathe spindle" design, which Smithy developed and popularized. The other design has the mill head mounted on the backside of the lathe bed. Is one design better than the other?

The combo machine with the mill head mounted behind the lathe bed has been around for over 60 years. It was developed by Emco-Meier and was sold by that company as the Maxi-Mat machine.

The design sold by Smithy was developed in the 1980's and quickly became popular because the Emco-Meier design had four disadvantages: 1) Much smaller milling capacity, 2) the mill can't be moved out of the way when you want to use the lathe (like you can with a Smithy combo), 3) the lathe turning cross feed capacity is limited because the mill head interfers with the travel of the work table, and 4) the size of the work table is limited because the mill head column is mounted so close to the lathe bed.

Among some combo machine operators the Emco-Meier design has the nickname "The Head Banger." This came about because an operator that is turning on the lathe can get focused on his project and forget about the mill head being in the way - the result being he bumps his head.

Overall, the Smithy Combo machine design offers more working capacityand higher efficiency and ease of use, compared to the traditional design.

What is the difference between the Granite and Midas Machines?

The biggest difference is that the Granite machines are bigger, more powerful and more automated than the Midas machines. The Granite has very good power feeds on X and Y, quick change gear box, and most importantly, a variable speed spindle. Speed changes are made with the turn of a dial. The Midas machines are more manual – gears and belts are changed by hand.

The Granite machines also have tooling that is easier and faster to use. The R8 spindle taper and D1-4 lathe chuck mounts are the industry standard for US productions settings. Tool changes are quicker and easier and the tooling is easy to find for both machine lines; the R8 standard tooling on the Granite machines is generally cheaper.

What is more important to you – time or money? If you are trying to make or save money and you need to maximize speed and efficiency, then the Granite machines are probably your better choice. If you have more time than money then maybe the lower-cost Midas is better for you.

What's the differences between the Granite 1324 and 1340?

Smithy model numbers give you the swing in the first two numbers and distance between centers in the last two. All Granite machines have a 13" diameter swing. The 1324 is 24" between centers while the 1340 is 40". All the other features are the same.

Who uses a Granite 1340?

Typically people who don't want to be limited by their options. Practical applications include:

  • Agriculture – drive shafts, PTO shafts
  • Auto – drive shafts, axles
  • Gunsmithing – black powder, bull barrels
  • Hydraulic Cylinder repair
  • Karting - axles

Specifications

What sort of tolerance can I expect from these machines?

The Granite specification is one-half to one thousandth of an inch production tolerance. The “TIR” (total indicated run-out) should not exceed .001” on any spindle assuming that you have followed proper setup procedures and have not exceeded the physical capacities of the machine or surpassed the safe feed/speed rates.

What are the machine weights and dimensions? Will they fit in a standard 8' pickup truck bed?

Yes, all Smithy combo machines fit into a standard 8’ pickup truck bed. A disassembled machine stand will also fit in the pickup bed, along with the machine.

Does your machine have the hole through the center of the spindle and what size is it?

Yes, all Granite machines have a 1.125” spindle bore through the center of the spindle for passing stock through.

Setting Up Machine

What are the power requirements for the machines? What plug style do I need for the 220 Volt Machines? What amp service is required?

Granite Classic and MAX machines run on 110 volt power and plug into a standard household outlet. The Granite I-MAX and I-MAX Elite run on 220 volt power and use a NEMA 6-15 plug.

Although the motors are DC motors, they still plug into a normal wall outlet. The AC to DC conversion is done by the motor controller or drive.

The motors draw from 8-16 amps. We recommend using a dedicated 20 AMP breaker.

How much space do I need to accommodate the machine?

A Granite normally takes up the space required to store a bicycle. When planning for your Granite installation be sure to account for movement around the machine and opening the pulley door on the left end.

Using the Machine

How easy is it to cut threads on the Granite machine?

The quick change gearbox makes choosing thread pitches very easy. The threading dial helps you stay on track while cutting threads. Cutting inch threads is straight forward. Cutting metric threads can be done, but it requires manually changing a gear. Good metric threads can be made on the Granite. The threading dial is not used when cutting a metric thread.

How good are the power feeds on the X and Y axes? Are they helpful?

You can power feed on the X or Y axis – whether using the lathe or mill. Easy to engage, with 21 different feed rate options for optimal surface finishes. Cross feed safety shear pin prevents damage to machine apron when travel limits are accidentally exceeded. The safety clutch on the lead screw prevents damage to the gearbox and transmission when travel limits are exceeded.

Who uses the Granite and what profession are they?

  • Small Production: Granite machines meet industrial tolerances and are used in a wide variety of production settings for small manufacturers or as a second machine.
  • Repair Shops: Auto, aviation, boat, gunsmith, farm, motorcycle, models. The list goes on and on.
  • Education/Military: Great tool for educational settings. All machining operations can be shown on one compact machine. Used extensively in military settings where space is at a premium.
  • Engineering/R & D: You would be surprised at the number of engineering labs and schools that have a Granite machine in the corner for when you need. Used extensively in R & D settings, by both big and small companies.
  • Small/Home Shop: Some Granite owners are current or retired machinists. The vast majority of Granite owners don't have a lot of experience with machining. The common interest is the need to make or save money by producing your own parts. Remember, all Granite machines are guaranteed to pay their own way.

Tooling for the Machine

What is included in the machine tool package that comes with the machine?

Smithy machines are shipped with tools that allow you to do basic milling and turning from day one. See the Features Tab on each machine's product page.

Do you offer a larger lathe chuck for the Granite? Can I exchange the standard chuck for it?

We offer a 8" 4-jaw chuck plus a 6" 4-jaw chuck but larger 3-jaw chucks are not offered at this time. Any D1-4 chuck will work on the Granite spindles. We do not offer "trade-ups" on the machines accessories or items in the free Quick-Start Tool Packs.

If I purchase a Granite machine and decide to put CNC on it later, will it be just a straight CNC or can I switch back from CNC to manual?

The advantage of upgrading our Granite machines with CNC is that you lose none of the original functionality of the machines. You can still retain the original power feed as well as the mechanical feed on the machines.
