Four axis CNC processing plant: commonly used which four kinds of processing center specific functions

(1) horizontal processing center
The spindles of the horizontal machining center are set horizontally.General horizontal machining center has three to five axes, often with a rotating shaft (or rotating workpiece table), spindle speed within 10 ~ 10000r/min, the minimum resolution is generally l micron, positioning accuracy of 10 micron - 20 micron.Horizontal machining center knife storage capacity is generally large, some knife storage can store hundreds of knives.The structure of horizontal machining center is more complex than that of vertical machining center.Horizontal machining center is more suitable for processing box parts.
The coordinate system of horizontal machining center is different from that of vertical machining center, namely X, Y and Z axes.And the cooling condition of horizontal machining center is not as good as that of vertical, especially for the boring, milling and drilling of the deep hole, the coolant is difficult to reach the cutting depth, therefore, must reduce the speed of the machine tool and feed, reduce the production efficiency.Compared with vertical machining center, horizontal machining center function, in the vertical machining center can not be processed on the workpiece, in the horizontal machining center generally can be processed.In addition, the rotary table of horizontal machining center has a lot of numerical control, a lot of indexing, workpiece clamping can realize the processing of multiple stations.Generally speaking, horizontal machining center has its advantages and disadvantages.Four axis CNC mill
2) multi-table processing center
Multi-table machining centers are sometimes called flexible machining units (FMC).It has more than two replaceable workstations, through the transport track can be processed workpiece tog with the work table (tray) to move out of the processing part, and then loaded with the workpiece to be processed work table (tray) to the processing part, this kind of exchangeable table can be set up multiple, to achieve multi-table processing.Its advantage is to be able to realize in the wire clamping, that is, in the process, the bottom of the table for loading, unloading workpiece, in addition to other work table are installed on the workpiece to be processed, start the machine tool, can complete the automatic processing of this batch of workpiece, the workpiece on the work table can be the same, can also be different.This can be handled by the program.Multi - table machining center has vertical, also has horizontal.No matter vertical or horizontal, its structure is more complex, the tool storage capacity is larger, the machine occupies a large area, the control system function is more complete.Fast calculation speed, large memory capacity.The most advanced CNC systems are used, so they are expensive.
(3) compound processing center
Composite machining center is also known as multi-face machining center, refers to the workpiece once loaded and clamped, can complete multiple surface processing equipment.The existing five-face machining center, which can complete the processing of five faces except the installation bottom surface after the workpiece is clamped once.This kind of machining center has the function of both vertical and horizontal machining center.Common five surface machining center has two forms, one is the spindle do or corresponding Angle rotation, can become a vertical machining center or horizontal machining center.The other is the work table with the workpiece to do the rotation, the spindle does not change direction and the realization of five surface processing.No matter which kind of five-face processing center has the shortcoming of complex structure and high cost.
(4) vertical machining center
The spindle of the vertical machining center is in a vertical position.It can complete milling, boring, drilling, tapping and cutting threads and other procedures.Vertical machining center is at least three axis two linkage, generally can achieve three axis three linkage.Some can be carried out five axis, six axis control, according to the number of simultaneously controlled by the process personnel to determine the machining center processing range.
The function of 5 surface machining center is more than the function of center of multistage machining, control system is advanced, its price is the multistage machining center that workbench size is same about 2 times.

Beyond Grease: A Deep Dive into Oilless Bushings & Why Viiplus Leads the Way

Friction is the enemy of efficiency. In countless machines, from massive industrial equipment to intricate automotive components, the constant battle against wear and tear dictates performance, longevity, and maintenance costs. Traditionally, grease and oil have been the go-to solutions, but they come with their own set of challenges: frequent re-lubrication, potential contamination, environmental concerns, and limitations in extreme conditions.

Enter the world of oilless bushings, also known as self-lubricating bearings or sliding bearings. These innovative components offer a smarter way to manage friction, delivering reliable movement without the need for external lubrication.

At Viiplus (www.viiplus.com), we don't just supply these components; we engineer solutions. Leveraging deep expertise in metallurgy and tribology (the science of friction, wear, and lubrication), we've become a leading name in sliding bearing technology. But what exactly are oilless bushings, and why should they be on your radar? Let's dive deeper.

What Exactly Are Oilless Bushings? The Science of Self-Lubrication

Unlike traditional ball or roller bearings that rely on rolling elements and require constant lubrication films, oilless bushings operate on the principle of sliding motion. Their "magic" lies in their material composition and structure, designed to provide their own lubrication at the bearing surface. This can be achieved through several key technologies:

1. Solid Lubricants Embedded: Materials like graphite, MoS₂, or PTFE are embedded directly into the metallic matrix (often bronze) of the bushing. As the shaft rotates or slides, a minuscule amount of this solid lubricant is transferred to the mating surface, creating a low-friction film.

2. Porous Metal Structures: Sintered bronze or iron materials are created with microscopic pores. These pores are vacuum-impregnated with oil during manufacturing. In operation, slight heating causes the oil to expand and seep onto the bearing surface, providing lubrication. When it cools, the capillary action draws the oil back in, creating a closed-loop system.

3. Layered Composites: These often feature a strong backing (like steel), an intermediate sintered layer (like bronze), and a low-friction overlay (often PTFE-based). The PTFE layer provides the primary sliding surface, offering extremely low friction.

Contrasting Logic: Oilless vs. Traditionally Lubricated Bearings

The Tangible Benefits: Why Make the Switch?

Choosing oilless bushings isn't just about eliminating grease guns. It's about unlocking significant operational advantages:

• Drastically Reduced Maintenance: This is the most obvious benefit. No re-greasing means less labor, less scheduled downtime, and simplified maintenance protocols. Imagine the savings across a factory floor!

• Enhanced Reliability: Lubricant starvation is a major cause of bearing failure. Self-lubricating bearings ensure consistent lubrication, leading to predictable performance and longer service life, especially in hard-to-reach locations.

• Superior Performance in Harsh Conditions: Oilless bushings excel where traditional lubricants fail:

  • High Temperatures: Certain types can operate at temperatures far exceeding the limits of conventional greases.

  • Low Temperatures: No grease means no stiffening or freezing issues.

  • Contaminated Environments: The absence of sticky grease reduces the ingress of dirt, dust, and debris.

  • Vacuum or Underwater: Ideal for applications where liquid lubricants are impractical or impossible.

• Cost Savings (Total Cost of Ownership): While the initial purchase price might sometimes be higher, the TCO is often significantly lower due to savings on lubricants, labor, downtime, and potential component failure replacement.

• Environmental Friendliness: Eliminating oil and grease leakage prevents contamination of products, machinery, and the environment. Crucial for industries like food processing, pharmaceuticals, and textiles.

• Compact & Simplified Designs: Without the need for lubrication systems (nipples, lines, reservoirs), machine designs can be more compact and streamlined.
