MI-1340/1237 Gear Drive Lathes - FAQ
Who buys these lathes from Smithy?
Schools purchase quite a few. Military organizations, R & D labs, and small machine shop/production shops are frequent buyers. The machines are designed and built to be good enuough to use in parts production settings - the reality is that, because the price is so reasonable, these lathes are popular for the home shop buyer.
Is the tool pack helpful?
The FREE tool pack is intended to give you a basic tool set-up to get you started when you get the machine. 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 lathes 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 level of quality committed to every step like these MIDAS lathes.
How long have you been selling these lathes?
Over 25 years.
Why do these lathes have Norton gear change boxes?
We have been selling these lathes for a long time and have found the traditional Norton gear box to be just as fast and easy to use as the newer “knob handle select” gear boxes. The big key is the Norton gear box is consistently more accurate on inch machines.
Do many lathe buyers also purchase milling machines?
Yes, the MI-1340 lathe matches well with the MI-409M 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?
The biggest change in the market recently is the increase in Chinese sellers coming into the market. In China there are many websites that pick a market and put a bunch of items from that industry up on their site to see what sells. These sites are coming into the US now. They generally don’t know much about the industry and they tend to sell cheap and buy knock-off products that don’t have the quality of the traditional sellers.
These companies generally have poor service support on products that are poor quality from the start. Before buying, make sure the company uoi are talking to has the technical people that can help you in the future.
Keep in mind also, when companies sell a wide variety of different products they are less likely to have the knowledge or backup parts and support to take care of uou after you buy their cheap product. Detroit Machine Tools 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 parts. Usually they already have something in mind they need to make. What is needed is a commitment to learn and curiosity. It will take time, but you will figure it out. 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.
