What is horizontal CNC machining center?

Horizontal CNC machining center refers to the CNC machining center with the axis of the spindle parallel to the workbench. It is mainly suitable for machining box parts. Horizontal CNC machining centers generally have three linear motion coordinate axes plus one workbench rotation axis. The working principle of the horizontal CNC machining center is to use the CNC program to automatically select different tools after clamping the workpiece at one time. The spindle speed can change automatically according to the program setting, and process multiple surfaces and multiple processes one by one according to the programming sequence. There is no need for multiple clamping and manual tool replacement. Horizontal CNC machining center can greatly improve production efficiency, but the CNC machining center with this structure occupies a large area and has high cost.

Notes for purchasing horizontal CNC machining center:

1. Specification: size of machining space, spindle speed range, feed speed range, size and range of cutting tools, capacity of CNC device and optional accessories, etc.
2. performance: static accuracy, moving accuracy, machining accuracy, positioning accuracy, thermal deformation and vibration resistance, etc.
3. Also need to pay attention to the adaptability of the body and the system, whether the maintenance is simple, the safety of the machine itself.

Precautions for use of horizontal CNC machining center:

Horizontal CNC machining center should be installed far away from the source, to avoid sunlight, no thermal radiation and not in the damp place. If there is a source near the installation of horizontal CNC machining center, seismic trench should be set up around the horizontal CNC machining center.  If there is no shockproof ditch will directly affect the machining accuracy and stability of horizontal machining center, a long time will affect the poor contact of electrical components, resulting in failure, affecting the stability of horizontal CNC machining center.

Horizontal CNC machining centers are usually placed in the processing workshop, and the machine tool equipment in the processing workshop is numerous, more or less resulting in power ups and downs. Therefore, the installation position of horizontal machining center must strictly control the voltage current and voltage, must be the power supply current and voltage control in the horizontal CNC machining center within the permitted range, must ensure that the current and voltage of the power supply is stable, otherwise it will directly affect the normal work of the horizontal CNC machining center.

Horizontal CNC machining center usually in the environment of not more than 30 degrees Celsius to normal operation, usually horizontal CNC machining center power distribution cabinet is installed exhaust fan and refrigerator, to ensure that electronic parts and central processing unit in constant temperature conditions.If the temperature and humidity is too high, it will cause the life of the components of the control system to be reduced, and cause the fault of horizontal machining center to increase gratuitously.  If the humidity increases, dust will increase on the integrated circuit chip directly cause the failure of poor contact and short circuit.

The user in the operation of horizontal CNC machining center, can not arbitrarily modify the basic parameters of the original CNC machining center, because the basic parameters of the original factory directly affect the dynamic characteristics of each component of the horizontal CNC machining center, only the gap compensation parameter value can be set according to the actual situation.  If you want to modify factory Settings, contact the manufacturer and modify factory basic parameters under the guidance of the manufacturer’s professional personnel.

Advantages of horizontal CNC machining center:

The workpiece only needs to be clamped once on the horizontal CNC machining center. The digital control system can control the machine tool to automatically select and replace the tool according to different machining processes, automatically change the spindle speed, feed speed of the machine tool, the motion track of the tool relative to the workpiece and other auxiliary functions, and complete the machining of multiple processes on multiple surfaces of the workpiece in turn. And there are a variety of tool change or tool selection functions, so that the production efficiency is greatly improved.

The workpiece in the horizontal CNC machining center only need a clamping, the digital control system can control the machine tool according to different processing procedures, automatic selection and replacement of the tool, automatic change machine tool spindle speed, feed speed and the tool relative to the workpiece movement track and other auxiliary functions, in turn to complete the workpiece on multiple surfaces of multiple processes of processing.  And there are a variety of knife change or knife selection function, so that the production efficiency is greatly improved.

Horizontal CNC Machining center due to the centralized process and automatic tool change, reduce the workpiece clamping, measurement and machine tool adjustment time, so that the cutting time of machine tool to reach about 80% of the machine time (ordinary machine tool is only 15 ~ 20%);  At the same time, it also reduces the workpieces turnover, handling and storage time between processes, shorts the production cycle, and has obvious economic effect.  Machining center is suitable for small and medium-sized batch production with complex parts shape, high precision requirement and frequent product replacement.

The matching guide rail surface is pasted with plastic, and intermittent centralized lubrication is adopted. The machine tool moves smoothly and has good accuracy retention. The CNC turntable is continuously divided to ensure good transmission rigidity and optimized damping performance, which greatly improves the dynamic rigidity of the transmission system.

Horizontal machining center and vertical machining center difference?

Horizontal CNC machining center and vertical CNC machining center have something in common is to milling function as the main function. The difference between the two is that their structure is different, the positioning of the product is different, and the form of the workpiece is not the same. The two spindle structure is different, horizontal CNC machining center refers to the spindle of horizontal machining center;  Vertical CNC machining center refers to the machining center whose spindle is vertical.

There are obvious differences between the columns of the two machining centers. Horizontal CNC machining center columns, are designed into moving column type, T type horizontal machining center, the column along the X to move, inverted T type horizontal machining center, the column along the Z to move. The structure of the mobile column requires that the column must be as light as possible under the premise of meeting the rigidity. Imported machine tools often use steel plate welding structure to achieve such a purpose. Vertical CNC machining center columns are generally designed not to move. In order to pursue rigidity, it is generally made as thick as possible. Occasionally also has the design into the moving column type vertical CNC machining center, moving column vertical CNC machining center workbench only to do X or Y movement, and the column will do Y or X movement, this design of the column drive motor has greater power requirements.

The workbench forms of the two are different. The worktable of the horizontal CNC machining center is only designed to move in X or Y direction. The worktable form is generally the rotary worktable of the dot matrix screw hole table. It is relatively easy to select the exchange double worktable. The worktable of vertical CNC machining center is usually a T-groove worktable with cross sliding table structure. There are two sets of motion mechanisms responsible for moving in a vertical direction. The worktable fed in X direction is covered on the guide rail responsible for feeding in Y direction. The chip removal conditions of horizontal machining center and vertical machining center are different. Due to the structural characteristics of vertical machining center, it is usually difficult to discharge the chips when machining the cavity or concave surface. In serious cases, it will damage the tool, destroy the machined surface and affect the smooth progress of machining. The horizontal machining center is easy to remove chips, and the machining condition is relatively ideal.

They have different tool magazine. Vertical CNC machining center commonly used hat tool magazine and disk tool magazine. Horizontal CNC machining center commonly used chain manipulator knife library. The number of linkage axes is different. The conventional vertical elevator is three-axis linkage, which can be expanded to four or five axes. The horizontal CNC machining center is equipped with four-axis and three-axis linkage, which can be expanded to five axes.

The handling is different. General horizontal CNC machining center processing workpiece, are relatively large, clamping difficult, not easy to monitor the processing process, operation and debugging is relatively difficult. And the vertical machining center clamping is generally very convenient, easy to operate, easy to observe the processing situation, easy to debug the program.

Their processing objects are different.the horizontal CNC machining center can complete the processing of the other four surfaces except the mounting surface and top surface after one-time clamping. It is suitable for processing box parts. After adding an angle head, it can realize pentahedral processing.

Therefore, it can be seen that the horizontal CNC machining center structure complexity is more than the vertical CNC machining center, the same working range of horizontal machining center price is often more than two times the vertical CNC machining center.
