SL280 - Slant Bed CNC Gang Tool Lathe - FAQ

What’s unique about the SL280 gang tool lathe?

Two things, speed and slant bed design: 1) Premium quality Bosch linear guides assure quiet, high speed axis movements – with rapid feed rates up to 1100 IPM.  2) The slant bed design provides access to the operator for set-up and tool changes.  The slant bed design also helps efficiently remove coolant and chips.

Why would I choose this lathe over one of the other tool room lathes?

High speed and precision make this lathe a fantastic value for small sized turned parts production. The heavy, slant bed design adds precision and easy access for set-ups and process observation.

Is the SL280 a production quality CNC lathe?

The heavy cast slant bed machine foundation is heat treated and annealed, and weighs in at over two tons. It has tolerances that match production machines. It has quality components and will hold up well under the high demands of production turning applications.

Will the lathe hold up? Is it good quality?

In addition to the SL280’s heavy, vibration damping foundation, this lathe is built with high quality components and construction. That’s how we are confidently able to offer an 18 month warranty. As mentioned, the lathe features a Siemens control and heavy duty spindle bearings. It also uses Schneider electrical components and PMI ball screws.

How is the accuracy? Will it hold up?

This machine is designed to maintain repeatability at .0002”. This lathe is also built on a heavy foundation machine base/lathe bed casting design. This assures ultimate rigidity and vibration damping – initially, and for the long-term life of the machine.

What are the standard features? What are the options?

The SL280 Lathe has standard specifications that include 5 HP spindle motor, pneumatic collet chuck, high speed slant bed gang table with tooling package and 3000 RPM spindle. Optional upgrades include: hydraulic pneumatic chuck, live tooling, bar feeder and 5000 RPM spindle.

Can I set this up myself? Do I need a rigger?

The SL280 is a heavy, bulky piece of machinery that should be handled with respect.  You should carefully and realistially consider your capabiliites before deciding to handle the moving of this machine on your own.  If you have a forklift that has sufficient fork length, size and load capacity, in addtion to a safety minded and well-trained operator, you should be able to safely remove the lathe from the truck it is shipped on and place it at its intended operating location. Some customers rent fork lifts and/or operaters to perform the task. 

Basic instructions for setting up the lathe are included in the operations manual. Of course, you can always call us with questions you may have.

What’s the warranty? How does it work?

AutoMateCNC Lathes have an 18 month parts replacement warranty. Detroit Machine Tools will send you the proper replacements parts for parts that prove to be defective.

The Siemens 808D control has a three year total (2+1) “in-field” warranty that is supported by Siemens USA.

How about service, can I do it myself? What if I need technical support?

The expectation is that customers who purchase a CNC machine tool will have the adequate mechanical and electrical know-how to handle service questions as they arise. Naturally, you can call and talk to a DMT technician with questions you have.

If you need technical support beyond telephone, on-line or email support provided by DMT technicians, we can help you find a local technician that is willing to travel to your location to provide assistance at your expense. We may already know of a technician in your area that we have worked with previously.

This lathe uses three phase power. Why? Is there an advantage?

The simple answer is that larger horse power machines operate more efficiently when using three phase power.

The advantage of three phase power is that your machines will last longer and operate with higher energy efficiency. Three phase power does not use more electricity than machines using single phase power. This also applies when using a phase converter – The average 10 HP phase converter runs on around 7 cents per hour of electricity.

I don’t have three phase power in my shop, what am I going to do?

The best solution is to use a rotary phase converter, which plugs into a standard 220V plug and converts power from the wall into the three phase power used by the machine.

If you do not have a phase converter yourself, you can purchase a high quality American made phase converter from us for a discounted price.

This is a simple plug and perform solution for the small shop operator. Watch this video to learn more about setting up and using a phase converter:


This video clip shows the Marton Brothers using phase converters to set up their new machine shop.

Siemens 808D CNC Control

The Siemens 808D is a real deal industrial control?

The Siemens 808D is a fully functional, industrial grade CNC control system that uses software based on the same software used in Siemens' larger, more industrial control systems. The difference is that the 808D is designed to be used on smaller machines.

Machine tools with real production capabilities, like AutoMateCNC machines, are best matched with a control system that has the power and functionality to do real production work, just like the Siemens 808D.

(NOTE - PERSONAL CNC CONTROLS: Mach3 and other “personal CNC” control systems are limited and best applied to hobby applications. Personal CNC systems are not easier to use than an industry standard control system, like the Siemens 808D. Also, the application of personal CNC systems is limited).

All AutoMateCNC machines come standard with the Siemens 808D Basic control, which can be upgraded upon request. Other control options include the Siemens 808D Advanced and Siemens 828D controls. Those that prefer using a Fanuc system can order any of our lathes or mills with a Fanuc Oi Mate TD CNC Control.

It says AutoMateCNC machines have servos. Is that true, even at this low price?

Yes, all AutoMateCNC lathes and mills use servo motors and drives on all axes. The biggest advantage of servo drives over steppers is the degree of accuracy and repeatability that can be accomplished. 

Other advantages of servos include: Rapid acceleration and higher speeds  2) High torque throughout the speed range 3) High efficiency  4)  Stay cool during long operations  5) Operate at very low noise levels – even at high speeds. Vibration free operation is one important reason for this.

PLUS, it has a closed loop control system?

Yes, this CNC control is a closed loop system. A servo-driven closed loop system is significantly more accurate than steppers. A closed loop system sends commands from the control out to the machine and then completes the communication process by sending data back that updates the control as to where the machining process is at any given time.

The system directly monitors motor position and velocity in real time. The system then automatically makes corrections to assure correct tool positioning. This assures high accuracy and maximum parts quality. PLUS, it assures smoother finishes and a reduced reject rate.

Does the control have conversational programming?

Yes, you can program standing at the control panel using fill-in-the-blank style forms. Each form has a graphic demonstration of the machining process you are programming. The control interface features include standard programming patterns like bolt hole circles, linear rays, full-contour definition, peck drilling, tapping, etc.

Do AutoMateCNC lathes and mills have a servo driven spindle? What’s the advantage?

Yes, all AutoMateCNC machines have a servo driven spindle, similar to the type of spindle drive motors used on larger CNC machine tools. A servo driven spindle provides much better torque, and assures constant torque throughout the speed range, even at low RPM.

Servo motors with an encoder are able to continually identify the exact radial location of the spindle shaft. This makes the servo driven spindle capable of rigid tapping, a function that most machine operators will eventually find a need for. The servo also allows for spindle positioning – an important consideration when using live tooling.

So, this lathe can rigid tap?

Yes, AutoMateCNC lathes and mills can be easily programmed to do rigid tapping operations.

Does the Siemens 808D handle larger programs well?

Siemens has a unique function that allows for the streaming of large program files direct from a USB. Large files are no longer a concern - other CNC systems lack this robust level of functionality.

Will this CNC Control work with my CAD-CAM system?

Yes, the Siemens 808D control has post processors for all CAD-CAM systems. If you are having a problem we will work with Siemens USA to resolve the issue.

What about training?

When you purchase an AutoMateCNC lathe or mill you receive free tuition (Value $299) to attend a day long basic programming and machine set-up class that we hold at our location in Ann Arbor, MI. Siemens USA also has many training webinars on their website.

I noticed that Siemens has a simulator for the 808C control. Is this helpful?

Yes, definitely. You should take the time to download the FREE Siemens 808D simulator on your computer. Spend some time getting to know the control system. Only with a little experience will you be able to see that the Siemens 808D control is as powerful and easy to use as other industrial CNC control systems on the market.

Many customers continue to use the simulator after they have their machines to develop machining programs while at their computer, rather than at the control panel. Once programs have been written and tested they can be easily transferred to the machine control via USB drive.
