The CNC turret lathe has become an integral component of modern metalworking and manufacturing industries because of its precision, efficiency, and versatility. Nonetheless, even though it is now the standard for every turret lathe, which is a machine tool that rotates metal workpieces against stationary tools for cutting and shaping, there are still some distinctions worth noting, particularly concerning computer numerical control.
Traditional Turret Lathe:
The design of modern turret lathes still features a large rotating disc, known as the turret, mounted on an axis which can be turned to bring different pre-fitted tools into position for machining operations. This is controlled manually by the operator, who pulls levers and shifts controls so that they can carry out various tasks such as drilling, facing, boring, threading, turning, and oiling various parts. While it may seem simple enough at first glance, there is actually quite a lot involved in getting all these things done properly by hand. However, with the arrival of CNC machines, traditionally-operated turret lathes are mostly used for educational purposes or historical understanding.
Automatic Turret Lathe:
In contrast to the traditional turret lathe, which relies on manual operation to move various tools into position for machining tasks, an automatic CNC turret lathe combines computer control with automatic tool changing. This means that it is now possible for the machine to have more than just one tool fitted onto its turret.
Furthermore, because of the CNC technology involved, there's no limit to what could be done with this type of lathe - higher production rates and a greater degree of accuracy are both possible thanks to all these features coming together in one machine. Automatic turret lathes equipped with CNC systems cater to businesses looking for efficient solutions that can handle large-scale production demands.
Swiss CNC Turret Lathe:
If one were to compare a Swiss-style CNC turret lathe machine with the rest of the automatic models available, they would find that it is somehow smaller in size yet has an adequate capacity for production. This particular workhorse is perfect for creating long, slender parts and its design includes a sliding headstock mechanism. It also employs a unique system of multiple tools capable of performing several tasks – all within one unit – which makes machining operations even faster and more efficient than before.
Multi-Axis CNC Turret Lathe:
Equipped with advanced CNC controls, multi-axis CNC turret lathes are capable of incorporating complex geometries with a high degree of accuracy. The term "multi-axis" refers to the numerous dimensions in which the machine can move; typically, this includes three regular ones (length, width, and height) plus an additional one or two for rotational purposes. Aside from its standard straight-cutting tools that come attached to turrets or towers, it may also be fitted with other specialized gadgets such as milling cutters, threading taps, and part-off tools used for precisely cutting off any parts that need to be removed. All these attachments allow it greater versatility when machining parts into more complex shapes than what ordinary lathes can manage.
The following table summarizes the key specifications of a CNC turret Lathe machine:
Tonnage
Tonnage is also referred to as the weight of the machine. A heavy machine often has great capabilities.
Maximum swing
It describes the maximum diameter of a workpiece that the lathe can handle when cutting.
Maximum length between centers
It describes the maximum length of a workpiece that the lathe can cut.
Spindle speed
It is the number of revolutions per minute the spindle rotates. Spindle speed affects the cutting speed of the lathe.
Control system
A turret lathe with an advanced CNC control system will have more automated features and programmability.
Tooling
The tooling system of a CNC turret lathe can be either turret indexing or automatic tooling changers.
CNC machines are sensitive and need proper maintenance. The tips below can keep the CNC turret lathe in good condition.
Regular Lubrication:
CNC turret lathes have many moving parts. Lubricate them regularly as per the manufacturer's manual. Choose the right oil and lubricate the parts efficiently. Regular lubrication reduces wear and tear, and it prolongs the lifespan of the machine.
Regular Cleaning:
Remove dust and debris by cleaning the machine regularly. Set up a cleaning routine and use the right tools to clean it thoroughly. Regular cleaning prevents build-up and reduces the damaging effects of dirt and debris.
Periodic Inspections and Adjustments:
Do periodic inspections of the CNC turret lathe. Check for damages or wear and tear in important parts. While inspecting the machine, make necessary adjustments to maintain optimal performance. The inspection and adjustments help to identify problems early so they can be fixed.
