Lathe machines with additional options such as Y-axis, sub-spindles, or specific selected options for automation are commonly called Turning Centres. These sophisticated machine tools are capable of machining complex parts – these go beyond standard OD & ID turning operations and may incorporate milling, drilling and tapping operations to complete the part in one setting. Taking a piece from raw part to finished product, such all-in-one machine tools significantly improves productivity.

To help you better understand what each tool is about and how you can use them, we will be starting a new series on the basics of CNC Machine Tools.

Standard machines are normally lower in price than complex ones. The latter may be the same machines fitted with additional option parts.

The bed of a CNC Lathe or CNC Turning Centre forms the main base for the whole machine. It is where the different components of the machine are mounted on. For example, the spindle stock which houses the machine’s main spindle; tailstock body; X and Z axis slide; optional Y-axis; and sub-spindle.

The size of the machine to be shipped will influence the packing and type of transportation (container or flat rack) used. This will in turn affect the price of CNC Lathe.

A simple CNC Lathe operates on 2-axis and the tool is located in a fixed position at 8 to 24 station turret. The rotating action of the part is called “turning”, hence certain types of CNC Lathes are called CNC Turning Machines.

For those new to the industry, the sheer variety, sizes and specialised uses of CNC (Computer Numerical Control) machines used in manufacturing can be mind boggling—from lathes, milling machines, and multi-axis machines to other machine tools.

A chuck is a vice-like structure that grips the workpieces to be machined. It is attached to the main spindle that rotates both the chuck and the workpiece.

Comprising the main motor, the headstock holds the main spindle where the chuck is mounted on. To ensure high performance, you need to consider if your machine tool’s headstock can handle high torque at low speed. This is an important consideration for tough materials.

The turret provides the possibility to change the cutting tools required for machining. Hence it is mounted on the tool turret. The size of the turret is determined by the number and size of tools that will be mounted on it.

For Hwacheon’s Hi-TECH Series, our gear-transmission system provides power and stability. The transmission assembly and spindle motor are also designed to limit heat and vibration transfer.

CNC Lathes are normally used for machining parts, where the material / part is clamped and rotated whereas the cutting tool is stationery mounted for OD (Outer Diameter) and ID (Inner Diameter) operations, e.g. shafts and pipes. They are ideal for parts that have same symmetry around an axis that could be chucked up (i.e. radially clamped) in the spindle.

Milling (cutting tool moves around stationery workpiece), boring and tapping (a tool that cuts threads inside hole) tools are normally driven by a separate drive system inside the turret. Depending on the application, the life tools (i.e. active tool) are mounted for axial or radial operational directions. These could be found in 3-axis CNC Lathes or CNC Turning Machines.

To ensure longevity, Hwacheon manufactures machine beds using high quality Meehanite cast iron. These help to limit heat distortion and provides solid mechanical stability. This ensures that the parts machined are consistently accurate.

The manufacturer and the country (South Korea, Germany, Japan, Taiwan, China, others) where the CNC Lathes are manufactured have a large impact on the prices.

Operated with Computer Numerical Control (CNC) systems and provided with precise design instructions, CNC Lathes are machine tools where the material or part is clamped and rotated by the main spindle, while the cutting tool that work on the material, is mounted and moved in various axis.

To ensure greater quality, Hwacheon manufactures 100% of its own spindles and parts of it. These can tolerate standard or higher optional rpm ranges, run with minimized vibration levels, depending on the application requirements.

Often known as the heart of a machine tool, the main spindle consists of a spindle assembly and the spindle drive system. These are some of the moving parts of the CNC machine tool, and they include motors, gears, and the chuck (more on it later). The C-axis drive which helps to position the material will also be assembled together with the spindle.

The guide way enables the tool to move horizontally and vertically to achieve a smooth cutting process. To ensure durability, rigidity and the highest accuracy are needed for this structure.

Modern CNC Lathes normally come with life tools that could work in multiple axis. For example, they could include both X and Y-axis, incorporate a second turret with different tools, or include a sub- / second spindle. These features help to be more effective and flexible for different milling, drilling and tapping operations.

Adding options like Y-axis, additional motor power, main spindle torque range, guide way system (linear ball or roller, box guide way), coolant through spindle (CTS) systems (30 or 70 bar), tool setter, chip conveyors (standard or special for aluminium), or spindle bore size (especially if BB or BB+) will result in added costs to a standard machine.

CNC Lathes are commonly used in industries such as oil & gas, automotive, aerospace, medical, electronics, mining, power plant, steel & paper mills, and ship building, just to name a few.

To ensure stability and precision in machining, the turret in, for example, Hwacheon’s Hi-TECH 550 provides a powerful clamping force, offering an index time of 0.2 sec/setup for fast and more stable machining.

In this basic set-up, the 2 linear axes can be used to perform OD/ ID (i.e. cylindrical machining) and facing operations, or drilling and tapping at the centre of the part. However, it doesn’t permit milling to be done.

Considered the workhorses of the manufacturing sector, lathe machines have been around ever since the 19th  century. Unlike its predecessors, today’s CNC Lathes are much more sophisticated and automated.

For example, Hi-TECH 450A standard machine has a chuck size of 10”. It can be fitted with 12” and 15” chuck, i.e. Hi-TECH 450A/B/C, providing at the same time bigger spindle bore diameters. Besides theses standard machines can also be fitted with milling functions, Y-axis, sub-spindle and also a longer machine bed (Hi-TECH 450A/B/C – std / MC / YMC / YSMC / LYSMC).

Additional options like special bearings, automatic tool changers (ATC) and hydraulic chucks will also impact the machine prices.

For example, Hwacheon’s Hi-TECH 200 standard machine is available with chuck size of 8” to 10” is lower in price than the Hi-TECH 230 standard machine which is also available with chuck size of 8” to 10”. However, HI-TECH 230 includes a much modern design and technology; and provides the possibilities to upgrade with various options to an even more sophisticated machine.

Tailstock are used to provide an extra support force on the other end of the component. This is necessary when machining long and extra-long work pieces (e.g. Shafts).

Here, the Y-axis is added to the machine so that off-centre machining operations can be performed. This will work well for more irregular and complex operations.

Tool holders are normally installed at the turret disk (a rotating disk allowing tools to be positioned and switched), they include both fixed and life tool holders. The life tool drive system is built-in.

CNC millingmachine

For Hwacheon’s Hi-TECH Series machines, the tailstock can be programmed to be positioned in semi-auto mode. This allows it to provide firm support and greater precision to the machined parts.

A CNC lathe machine is normally used to perform / produce precise round shapes with both an Outer Diameter (OD), and an Inner Diameter (ID). Practically all kinds of structures could be machined with this machine tool, depending on their needs in different industries.

In such machines, a second Turret is added to a 3-axis CNC lathe (e.g. T2-2T). Such machines would then have 2-axis at each turret (upper and lower turret) plus the C-axis on the rotating spindle. This enable the use of 2 tools at the same time on the part, hence reducing cycle times drastically.

Separate from the main spindle as an option, the sub-spindle works in sync with the main spindle to complete the first and second cutting operation in a CNC lathe. This improves efficiency and throughput per cycle. When named as a second spindle, the mechanism has the same capacity and power as the main spindle.
