Alternatives to using CNC machines

Although CNC machining has advantages over other manufacturing processes, it may not be suitable for all manufacturing applications, and other processes may be more appropriate and cost-effective. While this article focuses on the mechanical CNC machining process that uses machine tools to produce custom-designed parts or products, CNC control can be integrated into a variety of machines. Other mechanical CNC machining processes include ultrasonic machining, water jet cutting and abrasive jet machining. In addition to mechanical machining, chemical machining, electrochemical machining, and thermal machining can also be used. Chemical machining processes include chemical milling, blanking, and engraving; electrochemical machining processes include electrochemical deburring and grinding; and thermal machining processes include electron beam machining, laser cutting, plasma arc cutting, and electrical discharge machining (EDM).

What is a desktop CNC machine tool?

Companies that specialize in the manufacture of CNC machines usually offer a range of small, lightweight machines. Benchtop CNC machines, although slower and less precise, can handle soft materials like plastic and foam well. They are also better suited for smaller parts and light to medium production. The machines in the tabletop series are similar to larger industry standards, but their size and weight make them better suited for smaller applications. For example, a desktop CNC lathe has two axes and can handle parts up to six inches in diameter, which is great for jewelry and mold making. Other common desktop CNC machines include plotter-sized laser cutters and milling machines. For smaller lathes, it is important to distinguish between benchtop CNC lathes and benchtop lathes. Desktop CNC lathes are usually less expensive, but they are also smaller, and they are somewhat limited in the applications they can handle. A standard CNC table lathe typically includes a motion controller, cables and basic software. Standard CNC table lathes have a similar basic package but cost a little more.

What is CNC Turning Equipment?

Turning uses a single-point cutting tool to remove material from a rotating workpiece. Turning tool designs vary according to the specific application, and the tools can be used for roughing, finishing, facing, threading, forming, undercutting, parting off and grooving applications. The CNC turning process also utilizes a CNC lathe or lathe. Available lathe types include turret lathes, general lathes and special-purpose lathes.

What is CNC milling machine equipment?

Milling uses rotating multi-point cutting tools to shape the workpiece. Milling tools can be oriented horizontally or vertically and include end mills, helical mills and chamfer mills. The CNC milling process also utilizes CNC-enabled milling machinery, called a milling machine or milling machine, which can be oriented horizontally or vertically. Basic milling machines are capable of three-axis motion, with more advanced models accommodating additional axes. The types of milling machines available include manual milling machines, general milling machines, universal milling machines, and universal milling machines.

What is CNC Drilling Equipment

Drilling uses a rotary drill to produce a cylindrical hole in a workpiece. The drill bit is designed to allow scrap metal (i.e. chips) to break away from the workpiece. There are many types of drill bits, each with a specific application. Types of drills are available include pilot drills (for shallow or pilot holes), deep hole drills (for reducing the number of chips on the workpiece), screwdriver bits (for holes without pilot holes), and snap reamers knife (for enlarging the hole previously created). Typically, the CNC drilling process also utilizes CNC drilling machines, which are specially designed to perform drilling operations. However, it is also possible to perform the operation with a lathe, tapping machine or milling machine.

How does a 5-axis CNC machine work?

5-axis CNC machining describes a numerically controlled computerized manufacturing system that adds two axes of rotation to the 3-axis linear motion (X, Y, Z) of a conventional machine tool, enabling the machine tool to perform six Access five lateral surgeries in the lateral. By adding a tilting, rotating work holding (or trunnion) to the table, the milling machine becomes a so-called 3+2 (or indexing or positioning) machine, allowing the milling cutter to access five of the six sides of the workpiece. The 90° rotation of the prismatic workpiece eliminates the need for the operator to reset the workpiece. However, it's not exactly a 5-axis milling machine, since the fourth and fifth axes do not move during the machining operation. Adding servo motors on additional axes, plus their computer control (CNC part) will make it all in one. Such machines are capable of fully simultaneous contouring are sometimes referred to as "continuous" or "simultaneous" 5-axis CNC mills. Two additional axes can also be incorporated on the machining head, or separated - one on the table and one on the head.

What is CNC Turning？

Turning is a machining process that uses a single-point cutting tool to remove material from a rotating workpiece. In CNC turning, a machine tool (usually a CNC lathe) feeds a cutting tool in a linear motion along the surface of a rotating workpiece, removing material on a circumference until the desired diameter is achieved to produce a cylindrical part with external and internal features, Examples include grooves, tapers, and threads. Capabilities for turning processes include boring, facing, grooving, and thread cutting. When it comes to CNC mills vs. lathes, milling and its rotating cutting tools are better suited for more complex parts. However, a lathe with a rotating workpiece and stationary cutting tools is best for making round parts faster and more accurately.

What is CNC Milling？

Milling is a machining process that uses a rotating multi-point cutting tool to remove material from a workpiece. In CNC milling, the CNC machine typically feeds the workpiece into the cutting tool in the same direction as the cutting tool rotates, while in manual milling the machine feeds the workpiece in the opposite direction of the cutting tool's rotation. The operational capabilities of the milling process include face milling (cutting shallow flat surfaces and flat-bottomed cavities in workpieces) and peripheral milling (cutting deep cavities in workpieces, such as slots and threads).

What is CNC Drilling？

Drilling is a process that uses a multi-point drill to process a cylindrical hole in a workpiece. In CNC drilling, typically a CNC machine feeds a rotating drill perpendicular to the plane of the workpiece surface, resulting in vertically aligned holes with a diameter equal to the diameter of the drill used for the drilling operation. However, corner drilling operations can also be performed by using specialized machine configurations and work-holding arrangements. Operational capabilities for drilling processes include spot facing, countersinking, reaming and tapping.

CNC Machining Tolerance Table

When specifying parts to a machine shop, it is important to include all necessary tolerances. Although CNC machines are very precise, there are still some slight differences between repeats of the same part, usually about + or - 0.005 inches (0.127 mm), which is about twice the width of a human hair. To save cost, buyers should only specify tolerances for areas of the part that need to be particularly precise because those areas will come into contact with other parts. While there are standard tolerances for different levels of machining (as shown in the table below), not all tolerances are created equal. For example, if a part must never be larger than a measurement, it might have a specified tolerance of +0.0/-0.5 to indicate that it can be slightly smaller, but not larger in that area.
