CNC Machining Center, Engraving Machining, and CNC Engraving and Milling Machine Discussed

Posted On: January 27, 2022

CNC machining is one of the most popular forms of machining today. It is employed to create various small and large parts with utmost precision and accuracy. Repeatability, automation, and cost-effectiveness are a few benefits that make it superior to other types of machining. If you are familiar with this type of machining or have read about it somewhere, there are chances that you have heard of terms like CNC milling, engraving, and CNC machine center. Although you may get clarity from names, that is not enough. Many CNC enthusiasts still believe that these terms can be interchangeably used. This post aims to simplify these terms by offering in-depth insights into their application.

A Brief Overview of CNC Machining Center, Engraving Machine, and CNC Engraving and Milling Machine

Although these terms may closely overlap at times, they differ in terms of their applications. The following points will help you understand it better.

• CNC Engraving and Milling Machine:

  This machine can perform drilling, milling, grinding, and tapping along with engraving. This machine is operated at high speed and possesses high cutting ability and machining accuracy. An engraving and milling machine is used to process metals of HRC40 hardness and below. This machine is used for both fine and rough processing of metal products and fine processing of non-metallic products including resin, organic glass, wood, and so on. CNC engraving and milling machines are known for their fast processing speed, cost performance, and good finishes. These machines are used in metal processing, mold, medical, and other industries, where fine milling and finishing of molds are required.

• Engraving Machine:

  This machine also performs the same function as the above, but they are used to process small tools. The machine cannot perform cutting, and is only used for engraving. It is not suited for large workpieces. These machines are usually suited for engraving artifacts, and not used in industrial tool processing.

• CNC Machine Center:

  This is a highly automated machine and features several functions that are automatically selected and changed according to the requirement. Once the processed parts are clamped to the machine, the CNC machine can change tools according to the procedure; adjust its motion path, spindle speed, and feed rate, and so on. The machine center can perform several CNC machining operations like countersinking, drilling, boring, reaming, and various other procedures simultaneously. However, it is not suited for engraving processing. CNC machine centers are generally employed for creating prismatic parts such as frames, partitions, covers, and so on, which may employ multiple procedures at the same time.

Key Differences Between CNC Machine Center, CNC Milling and Engraving, and Engraving Analyzed

The following pointers will help you understand some key differences between the CNC machine center, CNC milling and engraving, and engraving.

• Spindle Power:

  CNC milling and engraving machines possess spindle power within ten kilowatts, engraving machines even lesser, whereas CNC machine center possesses a high spindle power of tens of kilowatts.

• Cutting Capacity:

  Among these, engraving machines are mainly used for engraving and are not suited for cutting, CNC milling and engraving machines are used for cutting large parts and finishing, and the machine center can perform heavy cutting as well as roughing.

• Accuracy:

  Engraving machines are suited for projects that require no high-end finishing, while engraving and milling machines and CNC machine centers assure high accuracy, as their functions are largely automated.

• Speed:

  CNC machine centers have light speed compared to engraving machine and engraving and milling machine. One of the reasons for their high speed can be attributed to their lightweight and compact design. The high-speed engraving and milling machine is equipped with linear motors with a speed of 120m/min.

Having understood the key differences between these machines, the choice of the right technique will depend on your application requirements. If you have been considering CNC machining for your next project, it is important to partner with an experienced CNC machining services provider such as BDE Manufacturing Technologies (BDE, Inc).
