CNC Lathe Considerations & Terminology

Date:Aug 22, 2017 Ages: Price: Type: Location:

When buying a CNC lathe, then there are numerous questions which you have to ask yourself before you start the procedure. A few of those questions will probably be rather obvious: Just how much axis travelling do I want? What dimensions toss should I search for? How many tool channels are around the turret? What’s the spindle bore dimensions? Etc.. But, there are different specifications which are equally as significant, but not necessarily so obvious: what’s the maximum swing space that my job will need? What’s the maximum turning diameter needed for the family of components? The initial set of queries over is relatively simple to answer, but the next group demands a better knowledge of lathes.

I’m often astonished at the amount of highly proficient CNC machinists and operators that will accomplish almost anything about a milling machine, but that is extremely uncomfortable and intimidated around a lathe only because they do not comprehend the significance of fundamental lathe language. That’s the intention of this report. MELFAB Engineering is committed to providing the best metal fabrication in Melbourne. I will attempt to describe the significance and benefit of some of these “not-so-obvious” characteristics which exist on a normal lathe spec sheet and endeavour to describe their definition and clarify why they may be a significant consideration when buying a CNC lathe.
Metal Fabrication
Maximum Turning Diameter: This only indicates the largest size of the component which may be switched on the device — with regular length tooling — without any collision or interference with protecting or other machine parts. Together with the X-axis retracted all how favourable, what dimensions of the component could be flipped safely…since it pertains to X-axis journeys of this machine tool. Though, in our case above, the component will technically “match” in this event, you must understand that you’re operating on the very border of the envelope…and should you’d like to hang out a tool from the turret further than ordinary — for one reason or the other — you’d probably NOT have sufficient X-axis journey to adapt the part.

Maximum Swing: identifies the biggest diameter component which may be spun from the throw without mechanical interference with protecting, cross-slide, or other equipment parts situated near the chucking region. Based upon the design and style of this machine tool in the query, this value might be bigger than the maximum rotation diameter cited previously…however, this does not follow you could turn a part bigger than that specified in the maximum spinning diameter.

Horsepower & Torque: torque and horsepower are evident considerations when buying a new device, but their requirement might not be quite as obvious in all scenarios. But if you’re more concentrated on large production or standard turning of small to medium sized components, then spindle RPM can be important than electricity on your circumstance.

As we’ve observed in the grinding area within the last several decades, high-speed machining is fast making its way to turning too.

Maximum Turning Length: quite much like this maximum turning diameter, that this specification suggests that the maximum part which may be turned depending on the mechanical limits and axis travels of this machine tool. Remember: the powerful maximum rotation length, to get a specific part, may be less than defined by using deeper or larger chunks, or tooling that sticks out from the surface of the turret further than that which is considered “normal”. In the situations you’d be introducing the chance for mechanical interferences — that would limit the period of the component that may be machined, even though the physical travels and constraints of this machine have never been altered.
