Comprehensive Guide: Understanding the Key Parts of a CNC Lathe Machine

Do you have any idea how many machines are manufactured every year? The number is huge, and if the machines’ number is massive, imagine how many metal parts are manufactured for them. Only if we focus on cylindrical parts, the production size is in billions of parts or maybe a lot more than that. For a long time, international and local manufacturers in the world have been manufacturing cylindrical-shaped machine parts with lathe machines. However, times have changed, and they have switched to CNC lathes for better results.

What is a CNC Lathe?

There was a time when people were bound to manual and semi-manual operations to manufacture machine parts. A lathe machine can work on cylindrical-shaped metal parts, but it requires much manual work to adjust workpieces. But when the CNC system entered the industry, everything transformed into rapid and better results. Then, the CNC lathe machines were introduced with more options and automatic operations. All they need is some instructions and a little supervision from an operator. This advanced lathe gives faster and better results.

Tool Turret

A tool turret can be defined as the tool manager. It works on the workpiece held between the headstock and tailstock. By carrying all the tools in its stations, it machines workpieces according to the command given by the control panel. It is one of the key CNC machine parts that changes tools rapidly for turning, drilling, knurling, etc. Some tool turrets have 4, and some have 8 stations, depending on the type of lathe being used. Heavy-duty metal is used for its production since it has to use high power for precision.

Chuck

It is one of the crucial parts of a lathe machine, which secures the workpiece for the machining process. A chuck clasps the workpiece tightly so it can not move or vibrate during multiple operations. Once it clasps the workpiece, it remains stationary. However, the spindle and the workpiece move. There are different types of chucks: three-jaw, four-jaw, hydraulic, magnetic, collet chucks, etc.

Tailstock

It is installed in the opposite direction of the headstock, providing additional support to hold the workpiece for machining. A tailstock works like the other hand to hold a workpiece for stable working. If you exclude it, the lathe machine will be incomplete. It is among those lathe components made of the toughest materials to bear the vibration during the machining process. The benefit of this component is it saves the workpiece from deforming or bending during intense machining for high precision.

Lathe Bed

This is the base of a CNC metal lathe machine, which holds the load of the entire system. It absorbs vibration for a stable process, and that is why it is made of the toughest materials. Shocks, vibrations, and high impacts are born by this single base to provide stability in the entire process.

Headstock

The headstock is like the engine of a CNC lathe machine. Why is it so? Because it generates the main power of the tool chuck and other areas during the machining process. The headstock is one of those lathe machine parts that help rotate the workpiece according to the command. It is on the left side of the machine powering the motor.

Pedal

You might have seen pedals in traditional lathes, where an operator controls the chuck and tailstock’s opening and closing operations. It is installed for the safety of the operator. CNC lathes have an automatic control system that does not have pedals in it. However, some CNC lathe machines have pedals for the safety of users, which offers additional control of hydraulic and pneumatic chucks.

CNC Control Panel

This is the brain of a CNC lathe machine, where the operator provides instructions through codes. These instructions turn a workpiece into a meaningful form. It is found in modern lathes, which are connected to a CNC system. Better precision, design, and accuracy result from giving the right commands to the panel.

Machine Tools

How can one miss machine tools among the key CNC machine components? You can understand their function from their name. Whether it is about grooving, knurling, drilling, or any other operation, they perform all of them precisely. Machine tools are attached to the tool turret’s stations, which operate automatically in the machine as per the commands given to the system.

Spindle

The last one is the spindle, which helps in the operation of the CNC lathe machine. It is responsible for maintaining the speed and rotation of the workpiece for a rapid machining process. It is a primary component in the CNC lathe that defines the precision level of the workpiece machining. A spindle spins the workpiece, allowing the machine tools to process it evenly.

There are other components also, but these were the key components that make the foundation of the machine.

5 Factors of Choosing Customized Machining Parts from a Wholesale Manufacturer

Every business wants to stay ahead in the market battle, which requires quality, quantity, and a better customer relationship. These factors are necessary for a company to survive for a long time in the market unless it is a monopoly. Since development has rapidly launched in the last few decades, industries have received new methods and customization tools. If we discuss customization, it is helping many businesses to satisfy their few categories of audience. Customization is becoming a part of every business to fulfill needs without leaving any stone untapped. Likewise, it has a cost too. That cost is high when these businesses have limited machinery and workforce. Companies are now outsourcing their few manufacturing areas to have custom machining parts for mega supply on time to combat this problem. We have gathered some factors why businesses of metal and plastic mostly need to contact a wholesale manufacturer.  1. Tight Tolerance Level Different types of metal or plastic parts have different tolerance levels. Generally, some limited kinds of components are usually available in markets, like fasteners, machine parts, and enclosures. They are available in a few sizes and shapes with little tolerance. But it is not the case with custom machining parts. Custom machining does the job regarding unnatural or different wall thicknesses. In this case, buyers look to have tight tolerance levels from manufacturers. The reason behind this is risk and high-cost involvement. The higher the tolerance level is, the more intricate the design is. It also indicates that bulk orders are taken for it because highly-precision CNC machines manufacture machine parts with high tolerance.   2. Specific Material Usage Sometimes, unique material is required for special needs, which includes alloys and composites, where specific machines like CNC machining tools are needed. Only some standard tools can be used for machining stainless steel or alloys. Only a specialized manufacturer can fulfill these bulk orders of specific materials here. Likewise, CNC machines are available in different types for various applications. It would be best to approach only an expert to deal with custom orders like specific materials’ manufacturing. That expert will help you get as many pieces as you want. There is another reason behind it, which is the compatibility of the machine with the material. You can’t use soft metal on a solid metal workpiece. It will damage your device as it is not manufactured to deal with it. Hence, it would help if you had a leading manufacturer with specialized features of CNC machining centers. 3. Complex Designs Coding and machine settings are essential for complex design. You must use more than just a standard CNC machine or a simple code to manufacture complex structures. It requires high precision via an ultra-fast spindle motor to get intricate designs. Tolerance level also works here to provide the thickness level of workpieces. Again, only an expert with years of experience in this field can offer such complex designs of metal and plastic parts in a large volume. It is also a reason why the complex parts are expensive because high-precision machines are required for them, which have a higher cost. However, a bulk manufacturer can supply these parts at low production costs because of economies of scale. Some machines or newly developed products have irregular shapes, which require customization options. 4. Specific Projects Some projects are limited, and they need customized components to complete. For instance, there are some machines whose parts can only be manufactured by a few manufacturers. When it comes to new electric vehicles or advanced gadgets, their manufacturing parts are very different from standard types, which is why these projects require customized machine parts. If you are also about to start a project and need custom machine parts, there are some reliable manufacturers worldwide. In addition, some companies look for limited designs or offer for a season to serve their loyal customers. Sometimes, companies launch these campaigns to capture the remaining market and need custom designs. 5. Large Volume at a Low Price The most important reason every buyer chooses to get a wholesale custom machine parts supplier is the opportunity for low prices. The quality is still high, and all the methods comply with international standards. Their price offerings are the sole factor that makes these manufacturers the apple of the eye of buyers. Their prices are low, and they cost-effectively manufacture custom parts. Also, consistency matters here because bulk production of these parts is faster than other modes.
