1. Calculate the size of the centre lathe you’ll want.
Lathes are classified by their swing and size, which are usually expressed as a pair of integers (i.e., 12 x 20). The swing, or length between both the middle of the head and the lathe bed, is the first quantity. It’s the largest workpiece radius that can be positioned between centres on that lathes. If your workpiece’s radius is 150 cm and your lathe’s swing is 12 inches, the workpiece will not fit between the centers of your lathe. The two digits is the bed size, which is the length here between headstock and tailstock. The bed in the previous case would’ve been 20 inches wide.
2. Ascertain that your machine shop is capable of handling it.
Even tiny bed size lathes may be rather massive, weighing hundreds of thousands of pounds. Heavy-duty lathes that are installed on the floor can be much larger, weighing millions of pounds based on the scale. Before you acquire one, evaluate your available floor space and make sure the lathe machine’s footprint does not exceed it. From modest bench lathes to massive, room-sized industrial CNC lathes, lathe machines come in all shapes and sizes. Consider the kind of lathe operations you’ll be performing and place your new lathe machine suitably on your shop floor.
3. Know The Basic Components of a Lathe Machine
A workpiece is “between centers” when it is held by the head and tailstock. The lathe bed may have a detachable section beneath the head to allow rotating operations on a product that exceeds the declared swing radius of the lathe machine. Lathes come in a variety of shapes and sizes.
Engine and tower lathes are the most common powered lathes. Most lathes work with a variety of materials, however they are frequently classified as metalworking or woodworking lathes. Wood lathes are often not as hard as their metal counterparts, despite being high-quality machine tools.
4. Recognize the capabilities of the lathe machine
Before purchasing a lathe, determine what sort of lathe work you want to perform and ensure that the new lathe is capable of performing those activities.
For example, if you’re buying a lathe machine to turn a 48″ long crankshaft, don’t choose one that only goes up to 44″.
5. Pick between a belt drive and a direct drive spindle
Machine tools lathes have two types of spindles: belt-driven and direct-drive, with the belt-driven kind being part of the original generation of lathes. Direct-drive spindles are substantially faster than belt-driven spindles in providing variable speed, resulting in lower cycle times. You can go from 0 to 6,000 rpm in half of the time with a direct-drive spindle speed lathe compared to a belt-driven spindle speed machine.
6. Take a look at the spindle speed, horsepower, and torque figures.
CNC Turning lathes are built to work with a certain diameter range. The majority of machine shops purchase a machine to accommodate a maximum working diameter. For instance, if you’re cutting two semi bars, the machinery will be constructed for smaller-diameter turning process with 6,000-rpm rotation speeds and the appropriate power and force. Larger spindle machines, but at the other hand, will have more torque due to the weight of the product in the jaw chuck. Sluggish spindle speeds and higher torque are required for larger workpieces.
7. Take into account the turning tools you’ll require for your new lathe
While your machine is a large investment, it isn’t the only thing you’ll need. Although your lathe will most likely come with such a jaw chuck, some types of lathe operations may require a faceplate.
8. Invest in a CNC lathe that gives you the most bang for your buck.
CNC machines are high-priced but very powerful machine tools that increase the speed and adaptability of any mechanical workshop or home workshop. CNC Masters has two CNC lathe machine that satisfy all of the requirements for speed and accuracy lathes. These CNC lathes are constructed in the USA and finally came with outstanding client assistance.
