The purpose of a tap in CNC machining is to perform "tapping" on a part—which, simply put, means creating internal threads that allow you to screw bolts into it.

Question 24

[Dispel doubts] What does a CNC machining center mainly do?

Accepted Answer

It is essentially a super-smart engraving machine that can "do it all."You can think of it as:A "master chef" with incredible knife skills: But instead of cutting food, it works with hard materials like metal and plastic. It can perform various techniques—turning, milling, drilling, tapping… you name it.A "tireless robot": Once you program it, it can process parts non-stop, 24/7, with speed and precision.A "high-precision replicator": Give it a blueprint (digital model), and it will mass-produce identical parts exactly to spec, down to the smallest detail.In short, many precision-made items like your phone case, car engines, and aircraft components are "carved out" by this machine.

A CNC turning center is like the PRO version of a basic CNC lathe. It comes with added features such as live tooling, which enables operations like simple drilling. The more advanced version would be the PRO MAX-level turning-milling center. It fully integrates the functions of both a lathe and a milling machine, though it does have some limitations. Its power is relatively limited, making it suitable only for parts within a specific range. That said, it improves machining efficiency by reducing frequent workpiece handling and machine adjustments.

Question 27

[Dispel doubts] What is the CNC program?

Accepted Answer

So basically, a CNC program is just a set of instructions—think of it like a recipe for a machine. It tells the CNC equipment what to do, step by step. Here’s what those commands usually cover:Where to move? (Toolpath): It guides the tool—whether to go in a straight line, make an arc, or move to exact coordinates.How fast to move? (Feed rate): This controls the speed at which the tool travels.How fast to spin? (Spindle speed): This sets the rotation speed of the tool or the workpiece.How deep to cut? (Cutting depth): It determines how much material to remove in each pass.Which tool to use? (Tool selection): Commands the machine to automatically switch to a different tool when needed.Coolant on or off? (Miscellaneous functions): Controls auxiliary features like coolant, clamps, and other accessories.It’s all about giving the machine clear and precise orders so everything runs smoothly and accurately.

Question 28

[Dispel doubts] What is the difference between grinders, lathes, and mills in CNC machining?

Grinder: For precision finishing, ensures smoothness and accuracy.Lathe: Processes cylindrical parts.Milling Machine: Handles complex-shaped parts.They have different roles and work together to complete part manufacturing.

Question 29

[Dispel doubts] What is the difference between an NC and a CNC lathe?

Accepted Answer

The core difference lies in the level of automation:NC (Numerical Control): Semi-automated. It relies on external physical media (such as punched tape) for operation and lacks built-in storage or computational capabilities. It represents the first generation of this technology.CNC (Computer Numerical Control): Fully automated. It features a dedicated built-in computer, allowing programs to be stored, edited, and executed with complex calculations. It is the absolute mainstream modern technology, belonging to the second and subsequent generations.
