As with all modern equipment machinery, machines have evolved and reduced in size over time. Despite advancements in technology and the cost the majority of smaller lathes are not equipped with CNC capabilities. lets see more about CNC conversion.
Many hobbyists can’t afford a CNC lathe as the machines are either too costly or too big. An CNC Lathe conversion kit is an excellent solution for small-scale shops or those who have a bit more time to spare.
What exactly is an CNC convertor kit?
The typical CNC Conversion kit that is used to upgrade an existing lathe comes with several new parts along with installation instructions. Motors and other equipment will enable the lathe to automatically move on the X Z axes. Additionally, there’s a new control unit as well as software.
Certain conversion kits are extensive, with full electronic packages that include an electronic control unit as well as programming software. Some kits are simpler and comprise of motors and other components needed to enable the machine to be CNC-capable however, they do not have the complete control software.
Do you think CNC conversion the best option for you?
If you run small-scale shop with old-fashioned machines that are now outdated CNC conversion kits are a great option to increase your capabilities without the expense of purchasing a new machine. The capabilities will be that of a true CNC machine, not an imitation and the reliability of your old machine after the conversion.
Of of course, CNC conversion kits are ideal for the hobbyist at home also, allowing them to upgrade their machine at a lower expense and try out CNC programming G-code, CAD, as well as the other aspects associated with CNC manufacturing.
What tools are useful to make a DIY CNC conversion?
There are a few other machining tools you’ll require to convert your lathe to a CNC machine. Because the tools that you have on the old lathe might not be equipped for the latest lathe technology Your CNC lathe may not perform as efficiently.
Mechanical components needed for CNC lathe operation
If you’re converting your manual machine to CNC, you must replace the existing mechanical components, like lead screws, using ballscrews as well as double nuts. We suggest changing these mechanical parts because the screws that drive lathe machines have backlash and are not compatible with CNC operation. Ball screws however are extremely low to no backlash. They make a great option for driving CNC lathe machines.
While you might require purchasing double nuts and ball screws independently, apart from the kit for conversion but this is not always the scenario. It’s because a lot of manufacturers offer these parts in their lathe CNC conversion kit.
Electrical components for your CNC lathe
If you are purchasing the CNC lathe CNC convertor kit you’ll have to purchase some electrical components needed to operate CNC machine.
In the beginning, you must buy a top-quality control, limit switch stepper drivers, as well as mechanical probes to efficiently control your machine’s X Z, and Y movements. The control for the spindle comes after and, if you wish to regulate the RPM manually using buttons, we suggest buying a VFD.
Then, you’ll need a computer at the opposite side of the controller to use your CNC software and to send commands to your lathe. Once you’ve purchased the machine you’ll be able to install and run a variety of CNC software, from Mach3 and GRBL up to the LinuxCNC.
How can you convert your current lathe to CNC using a conversion kit?
The procedure for conversion is different based on the lathe machine used and conversion kits. However, generally speaking you can follow the procedure involves:
Mechanical retrofitting your lathe
The initial step in CNC conversion involves mechanical retrofitting. This will require you to take apart the entire lathe prior to setting up the kit for conversion. It’s not as simple as replacing the parts since disassembly and reassembly involves handling large and complicated machine components.
In the beginning, you must remove the axes of your lathe. Then replace those screws that are leading with balls on every axis. You can’t manually take out the machine’s Z axis since it could weigh up to 1000 pounds. Therefore, we suggest using an engine hoist in order to quickly lift and move the Z axis.
Additionally the lathe could be secured to the floor using bolts and nuts which you have to remove. Once each axis has been taken off then the CNC components can be added separately.
Connecting stepper motors to your machine’s axis is next step to lathe CNC conversion. In this step, make sure that the motor you choose to use can take the load on the Z axis. After you’ve joined your stepper motors onto the X Z, and Y the axes, you’ll have to move the motors.
There’s more to mechanical retrofitting than that.
It is necessary to square the Z Axis and make sure it is parallel to the work table before you are able to operate the lathe. This method, also known as tramming on the machine, can be executed using a tramming indicator.
If the lathe hasn’t been properly cut, you can reduce the height of the column and alter its leaning by using the steel sheets that are under the base of the machine. After you’ve completed tramming on the column, do the same thing for the spindle, making sure that it isn’t moving. The lathe is now in use after having trammed in both columns as well as the spindle.
Electronics for installation that allows CNC conversion to your lathe
After retrofitting mechanically after retrofitting, electronic components should be added to make it possible to run the CNC lathe to work on your machine. Before installing electronic components to your machine, it is essential to initially install the stepper motors on every axis.
For the first time, you’ll have to set up a control system for your stepper motors. Control system as you will see, is the primary vital part of your machine since it permits that the turning machine to become computer controlled instead of hand-operated.
Apart from your control unit, you must purchase other electrical components to run the lathe. A non-regulated DC power supply as well as three limit switches along with two probes included.
Additionally, we suggest purchasing three motors with steppers that will power the stepper motors on your lathe.

After that, you need to choose the controller that controls the benchtop CNC lathe. This is something you must select carefully as it should have compatibility for CNC software. It is possible to make use of it if the CNC control software is compatible with Mach3 or LinuxCNC. GRBL. This is because these are the most famous CNC programs, and the majority of well-known lathe conversion kits have them included in their kits.
Spindle retrofitting to be able to make use of an CNC converter kit to convert lathes
The spindle system needs to be retrofitted in order to enable a reliable computerized conversion on your lathe.
Therefore, if your machine features a spindle motor driven by gears system, it is necessary switch it over to the belt drive motor. A belt drive lathe’s CNC converter kit for instance can be used to convert your lathe.
It is also beneficial to purchase an VFD motor controller to suit the spindle motor. This motor can control the spindle on your machine. The manual buttons on VFDs can be usually utilized to alter or increase an RPM of the spindle.
Closing it up
The most beneficial project you can create to improve your shop’s efficiency is the DIY mill CNC conversion. All you require is the right kit to convert. Although CNC conversions can seem difficult, if you’re comfortable using milling equipment, you are able to convert them easily to CNC.
