At Kazida, we understand that choosing the right equipment can be daunting for those new to the machining industry. Terms like CNC machining centers, engraving-milling machines, and engraving machines often lead to confusion. To help you make informed decisions, let’s break down the key differences among these three types of machines.

Unique to China, the term "engraving-milling machine" describes equipment designed for both engraving and milling tasks. These machines build upon the foundation of engraving machines by increasing spindle and servo motor power while enhancing the machine bed's stability. They maintain high spindle speeds, making them versatile for high-speed operations.

Engraving-milling machines excel in precision and cutting power, capable of processing materials with hardness exceeding HRC60 in a single operation. They are widely used for tasks like precision mold core processing, batch aluminum product manufacturing, copper electrode machining, shoe mold fabrication, and jig creation. Their high cost-performance ratio, fast processing speeds, and exceptional surface finish have made them an essential tool in the machining industry in China.

Known as "computer gongs" in southern China, CNC machining centers are versatile tools that automate complex machining tasks. Once the workpiece is clamped, the CNC system manages tool changes, spindle speed adjustments, feed rates, and movement paths.

These machines can perform a variety of processes, including drilling, reaming, tapping, milling, and boring, across multiple surfaces. By automating these steps, CNC machining centers significantly reduce manual errors, setup time, and downtime, improving overall efficiency and precision. They are ideal for heavy-duty cutting, making them suitable for processing large molds and hard materials. CNC machining centers are categorized into vertical and horizontal models based on spindle orientation.

Engraving machines are designed for high-speed operations with small tools, focusing primarily on "engraving" tasks rather than heavy cutting. Their high spindle speeds and low torque make them suitable for working with lighter materials like wood, acrylic, and soft metals.

While cost-effective, engraving machines lack the precision and cutting power of CNC machining centers or engraving-milling machines, making them less suitable for mold development. However, high-end engraving machines equipped with advanced spindles, such as air-floating spindles, can handle tasks like polishing metal casings and processing wafers.

CNC machining centers typically reach up to 8,000 rpm, while engraving-milling machines operate between 24,000 and 30,000 rpm. Specialized engraving machines designed for high-gloss finishes can reach speeds of 80,000 rpm with air-floating spindles.

CNC machining centers have the highest power, ranging from several kilowatts to tens of kilowatts. Engraving-milling machines come next, usually below 10 kilowatts, while engraving machines have the least power.

CNC machining centers excel in heavy cutting and rough processing, engraving-milling machines handle precision tasks, and engraving machines are ideal for light cutting or decorative work.

Engraving-milling and engraving machines are lighter and faster, with feed speeds of up to 120m/min for high-speed models. CNC machining centers, being heavier, are slower in comparison.

CNC machining centers typically have larger tables, starting from 830mm x 500mm, while engraving-milling machines max out at 700mm x 620mm. Engraving machines have the smallest tables, often below 450mm x 450mm.

Outside of China, the term "engraving-milling machine" is uncommon. Globally, the machining industry often categorizes such equipment as small CNC machining centers, reflecting their overlapping capabilities. The decision to choose between an engraving machine and a CNC machining center should depend on production needs. Additionally, high-speed cutting machines, also known as HSC machines in international markets, further expand options for medium-scale cutting tasks.

At Kazida, we aim to simplify these distinctions and help you choose the right machine for your needs. Whether it’s for rough cutting, precision milling, or decorative engraving, our team is ready to provide tailored recommendations and support.
