MIDAS Gear Drive Milling Machines - FAQ
Who buys these mills from Smithy?
Businesses/Professional:  Schools purchase quite a few. As so military organizations, R & D labs, etc.  Small machine shop/production shops are frequent buyers.
Garage/Home Shops:  The machines are designed and built for professional parts production settings.  Because of the quality features - and reasonable price - these rugged milling machines are also popular with home and garage shop machinists.
Is the tool pack helpful?
The FREE tool pack is intended to proved a basic tool set-up to get you started when your machine arrives. It’s a balanced set of tooling, but you will likely need more tooling once you figure out specific projects you want to do.
What do you mean by “Inspected Twice?”
Each lathe is inspected by trained company employees at the factory - PLUS, a second complete inspection is performed at our warehouse in Ann Arbor, MI before it is sent to the customer.
Why are these mills better than others on the market?
For a machine tool to be truly great it must have attention paid to every step of its development - design, production, quality control, testing, and after sales support. No other bench top lathe on the market, at this price, has the same level of quality commitment at every step as these MIDAS mills.
How long have you been selling these mills?
Almost 30 years.
Do many lathe buyers also purchase milling machines?
Yes, the MI-1440 lathe matches well with the MI-409MZ milling machine - a machine shop combo that was built to last. Many customers buy this combination.
Are there machine tool sellers out there now that tool buyers should be aware of?
Recently there has been a number of Chinese trading companies coming into the market. They have a website that, at first glance, looks like an American company.  These trading companies put a lot of products on their website - most of which they know very little about.  They go out and find machines that look like established US companies, but really the majority of these products are low quality.  The trading company sells cheap, but the products they sell don't match the quality of traditional US sellers.
These companies generally have poor service support on products that are poor quality from the start. Before buying, make sure a company has the technical people on staff that can help you in the future.
Smithy focuses on a few quality products and works to offer the very best product and service for these products.
Do I need to be a machinist to use the machine?
NO, many buyers of these machines don’t have the experience.  What they have is the need to make a certain part or product. What you need is a commitment and curiosity.  We have a set of machining training videos on our website. You can usually find classes at a local community college or vo-tech school. Get a machine and get going! You won’t be disappointed.

2. Basic Delivery – Pick up from terminal

This delivery method will bring the machine to the Estes terminal nearest you for pick up. Once the machine arrives at the terminal, they'll call you to let you know it's ready for pick up. They will load the machine into an open bed pickup, cargo van or trailer. You will need to bring with you an ID and proof of purchase which will be sent to you during the sales transaction. To find the terminal nearest you click the following link. http://estesexpress.com/WebApp/PointsInquiry/

3. Business Delivery – Forklift

Estes will bring the machine directly to your business for easy offloading. For this delivery method you must have a forklift and your business must be semi-trailer accessible. If you are unsure about semi-trailer accessibility please contact the terminal to discuss options.

4. Deluxe Delivery – Residential

Curbside delivery! Estes will drop the machine onto the ground, curbside, at the end of your driveway. Estes will generally use a box truck with a lift gate. That is not 100% guaranteed, so if your residence doesn't have semi-trailer accessibility please contact your local terminal to discuss options. http://www.estesexpress.com/WebApp/TerminalList/ Also, there must be someone home to sign for delivery.
