The machining centers represent the most versatile CNC machine tools in the metalworking industry, allowing multiple operations to be performed within the same production cycle with high precision... and automation. At Makinate, you will find a wide selection of high-quality used machining centers from the best international manufacturers such as Mazak, Mori Seiki, DMG, Doosan, Hermle, Okuma, Mandelli, and many other leading CNC machine tool brands.
Main Features of Machining Centers
Machining centers are machines designed to significantly reduce component manufacturing times and machine setup times. Common features of all machining centers include a milling head (spindle) where the cutting tool is mounted, a table to which the workpiece is fixed, and a tool magazine that allows full automation of the machining cycle. Unlike lathes, in machining centers the workpiece remains fixed on the table while the rotary motion needed for material removal is provided by the tool, ensuring maximum flexibility in milling, drilling, boring, and threading operations.
Types Based on Spindle Orientation
Machining centers are mainly differentiated based on the spindle orientation:
Vertical machining centers: with a vertically oriented spindle, ideal for machining medium-sized components with top access
Horizontal machining centers: equipped with a horizontal spindle and pallet changer, perfect for mass production of medium to large parts with high automation
Multi-Axis Configurations
Vertical machining centers in their traditional standard configuration are equipped with 3 axes: 2 axes (X and Y) on the table determining longitudinal and transverse movements, and one axis (Z) on the spindle head determining vertical movement. To machine more complex parts and multiple sides of the same component without repositioning, which would waste time, 4, 5, or more axis machining centers are available. Typically, the fourth and fifth axes are rotational axes on the table and spindle head, allowing machining on five faces of the workpiece with a single machine setup.
Continuous and Indexing Axes Machining Centers
Multi-axis machining centers differ based on the type of axis movement. In 4 or 5-axis continuous machining centers, all axes can move simultaneously during machining, allowing the machine to create even very complex geometries during the production cycle. In machining centers with indexing axes only, the fourth and fifth axes are locked in the desired position before starting the standard 3-axis milling program. In simultaneous axis machining, no operator intervention is required to orient the tool, as this is done automatically by the machine.
Gantry-Type Machining Centers
Another important distinction lies in the structural configuration of machining centers and the distribution of the traditional movement axes (X, Y, and Z). To machine medium to large and heavy parts, some configurations redistribute the movement axes to the spindle head, relieving the table from movement duties and consequently increasing its load capacity to allow clamping of even very heavy components. This technical solution enables gantry-type machining centers to maintain very high execution speeds even when machining large-sized components.
Automation with Pallet Changer
Another classification worth noting is the presence or absence of a pallet changer, which allows an even higher degree of automation by enabling masked-time machining. The operator can set up a second pallet with the workpiece while the machine is still running. Once the job is completed, the machining center moves the finished pallet out of the work area and brings in the pallet with the new workpiece. This solution minimizes downtime and machine stoppages due to setup. Horizontal machining centers always include a pallet changer in the standard dual-pallet configuration; for larger series production, it is possible to have an automatic multi-pallet system capable of holding 6 or more pallets, ensuring greater operational autonomy.
Why Choose Used Machining Centers at Makinate
Purchasing used machining centers is a winning strategy for manufacturing companies looking to reduce investment costs while accessing advanced technologies. Each machining center in our catalog is accompanied by a detailed datasheet with complete specifications on the number of controlled axes, axis travels, table dimensions and load capacity, spindle characteristics, type of installed CNC control (Fanuc, Heidenhain, Siemens, Mazatrol), tool magazine capacity, and optional equipment. Used machining centers offer reliable performance and allow companies to optimize investments without compromising quality and precision in mechanical machining.
