A machining center (MC) is a high-tech computer-controlled machine tool capable of carrying out a wide range of machining operations and processes. In contrast to conventional machines with manual tool change systems, an MC is equipped with an automatic tool-changing mechanism (ATC) that enables the use of multiple cutting tools throughout the machining process.
Quick changes of the cutting tool make production more efficient and reduce cycle time. The versatility, accuracy and ability to handle complex operations like milling, turning, boring, drilling, and more are at the heart of an MC.
CNC Machining centers are known for versatility, with a wide range of types available to suit different needs and applications. Let's take a closer look at the main types:
Horizontal machining center (HMC) is distinguished by its spindle's horizontal orientation, offering strong rigidity and sturdy construction to handle heavy workpieces effectively.
A HMC typically includes an automatic pallet changer (APC) system with six to eight pallets, enabling continuous work on various pieces without the need for manual intervention.
Tailored for large-scale production, HMCs are recognized for their high material removal rates (MRR). Their horizontal configuration allows for efficient machining of up to 4 surfaces without the need to reorient the workpiece.
By directing metal chips away from the workpiece, HMCs prevent accumulation and improve suitability for operations such as boring.
Certain HMC models even come equipped with a spindle that can rotate to a vertical position, falling into the universal machining center category.
Frequently utilized in the manufacturing of components like automotive parts and gears, brands such as SmartekMech produce HMCs renowned for their reliability and performance.
Vertical machining centers (VMCs) have a spindle aligned vertically, providing easy access and flexibility. These machines often come with ATC and APC systems in a compact design, perfect for limited spaces or personal use.
The vertical spindle alignment may lead to metal chips gathering on the workpiece surface, requiring regular cleaning.
VMCs come in 3-axis to 5-axis models, allowing for workpiece access from different angles without the need for manual adjustments. Companies such as SmartekMech produce VMCs used for various tasks like engraving, mold processing, and milling different materials.
