Spindles
Our four-axis horizontal machining center features a direct drive motor spindle with high torque and high speed, which can handle the finishing of aluminum alloys and high-hardness metals. Some models use a dual-spindle structure to meet your multi-material processing needs. In addition, the spindle has a built-in circulating cooling system (oil cooling, water cooling, or air cooling) to provide efficient cooling and heat management for the spindle, ensuring long service life and processing accuracy.
Turret
Our four-axis horizontal machining center can be equipped with single or double turrets, featuring a high-speed automatic tool change system that achieves high-precision, repeated tool change positioning accuracy. It is also optionally equipped with a large-capacity chain tool magazine or disc tool magazine, as well as a side-mounted tool changer.
CNC
The CNC system of our 4-axis horizontal machining center can ensure that the tool center point moves accurately along the predetermined trajectory, which is the foundation of high-precision machining. Besides, the CNC system can also control the coordination of the rotary axis with other axes. In addition, some models of CNC systems are compatible with CAD/CAM software and have a good human-computer interaction interface, which is convenient for operators and programmers to operate and program.
High Rigidity
Our 4-axis horizontal machining centers utilize high-strength HT300 cast iron for their base, columns, and housing. This high-strength cast iron offers excellent damping properties and thermal stability, effectively suppressing cutting vibration and thermal deformation. The symmetrically distributed columns provide even force distribution and greater resistance to overturning.
What are the advantages of 4-axis machining?
Compared to 3-axis machining, the addition of the rotary axis to the X/Y/Z linkage enables the 4-axis machining center to complete more precise processing with fewer clamping and adjustments, making your production line more automated.
Moreover, for small to medium batch production of workpieces, 4-axis machining strikes a balance between efficiency and cost.
What are the advantages of a horizontal machining center?
First, the machining area of the horizontal machining center is located at the bottom. The chips and coolant fall naturally into the chip groove under the action of gravity. The chips are not easy to accumulate on the surface of the workpiece, which can not only ensure the quality of the workpiece but also protect the tool. It is very suitable for the processing of cast iron, high-temperature alloys, titanium alloys, and soft and sticky materials.
The horizontal machining center is naturally adapted to the pallet system. Multiple pallets can be pre-loaded with workpieces, allowing clamping and processing to be carried out simultaneously and greatly reducing non-cutting time. While the machine tool is processing one pallet, the operator can load and unload other pallets in a safe area, ensuring a safe operation.
Second, the horizontal machining centers are usually designed with higher load and capacity, making them suitable for machining workpieces with larger sizes and weights.
3-axis, 4-axis, or 5-axis, how to select?
The initial cost of a 3-axis CNC machining center is low, and programming is relatively simpler. However, since secondary clamping is required when performing multi-sided machining, large errors are prone to occur, resulting in low efficiency. Therefore, it is suitable for machining flat workpieces such as valve plates and brackets, and is also the first choice for producing large quantities of single parts.
A 4-axis horizontal CNC machining center is more suitable for box parts (such as engine cylinder, valve block) and flanges, bushings, cams, cylindrical carvings, turbine blades, and other multi-faceted processing of cylindrical surfaces, inclined surfaces, and simple curved surfaces.
Five-axis horizontal CNC machining centers are capable of processing more complex curved parts, such as integral impellers, aircraft engine blades, precision medical devices, deep-cavity molds, and special-shaped thin-walled parts. However, five-axis horizontal CNC machining centers have higher requirements, including hardware/software costs, senior programmer salaries, and maintenance costs.
When choosing a multi-axis horizontal machining center, you need to consider the type of workpiece, the process required, your budget, and the production batch size.
