What is CNC cylindrical grinding machine?

CNC cylindrical grinders are also called CNC grinders or CNC cylindrical grinding machines. They are essentially the grinding machines that are controlled by the CNC system. CNC stands for Computer Numerical Control which refers to an automated unit that controls the machining tools by a computer. A cylindrical grinder has its name from the grinding spindle that has a cylindrical figure; a machine as such performs grinding works by the rotary movement of the grinding tool which is driven by the spindle.

The grinding work that is conducted by a CNC cylindrical grinder goes this way: the operation is pre-programmed on a computer and the CNC system gives a series of instructions to the grinder to carry out the very operation. The programming process is referred to as CAD which stands for Computer-Aided Design. The most popular CAD software to date is AutoCAD. Since the movement of the grinding tools as well as the work pieces is precisely controlled and executed, the end result of the operation can be optimized.

CNC Machining Center​

The two fundamental elements of a CNC grinder is the CNC system that instructs and controls and the grinding machine that executes. A grinding machine is the machining equipment that uses a rotating grinding wheel to remove material from a given object so that the object can be shaped into a desired configuration. As technology advances over time, the grinding machines in general have evolved and turned into a more comprehensive machining center.

A conventional cylindrical grinding machine is only able to perform limited types of grinding operations. However, a CNC machining center is capable of performing a wide variety of machining operations by means of changing the machining tools mounted on the spindle head. The CNC machining center is also known as the CNC turning center. Almost any machining process that involves the rotation of the spindle head can be conducted by a turning center and the automation of the machine enabled by CNC system further lifts its capability.


Efficient Tool Change

The automation of machinery is one of the key advantages of a CNC cylindrical grinder as well as the CNC turning centers so to speak. The automation of machinery is not only realized in the machining process, but also the change of machining tools. During a conventional machining process, the drill bits or machining tools are changed manually by machinists which is rather time consuming. Yet, CNC automation allows the machine to change the tools automatically and rapidly. On top of machinery automation, the invention of power turrets further improves the process to another level.

A turret head is a platform which allows multiple machining tools to be mounted. Driven by the main spindle head, the tool change process conducted by a power turret becomes simpler. Since the tools are all mounted onto the turret, the unloading and reloading of tools are no longer necessary. The spindle only has to position the tool to the machining site by rotating the turret and the machine is ready to proceed on the next round of machining. A CNC cylindrical grinder can incorporate with a power turret to better the overall performance and productivity of the machine.

Non Woven Fabric Wallpaper - Tianjinsheng

图片
  Non-woven wallpaper  has been a popular product on the wallpaper market since the 1990s. The compacted mixture of cellulose and polyester fibers provides very good dimensional stability and is highly resistant to mold and mildew growth.   Blends of cellulose and polyester fibers Blends of cellulose and polyester fibers, i.e. natural and synthetic fibers, are called "nonwoven materials". This revolutionary wallpaper material was introduced to the market in the early 1990s. Pulp or cellulose is obtained from chemically treated plant fibers. Polyester is a synthetic fiber that is very important in the textile industry.   Dimensional stability due to compaction In the production of nonwoven wallpapers, natural and synthetic fibers are compacted together with a binder, resulting in very good dimensional stability. The two types of fibers are fused together to form a tear-resistant, stable unit that is still breathable. The compaction process also ensures that individual...

5 Tips for Protecting Pipe Threads

图片
  1. What Do Pipe Threads Need Protection From? When connecting any section of pipe to another, thread engagement will determine the strength and seal quality of the string. The thread profile and pipe specification will determine the axial loading that a specific section can handle. To ensure every connection works optimally, pipe thread protectors   can reduce the risk of a compromised thread profile.   The types of elements that pipe threads need protection from include:   • Corrosion and rust when exposed to the elements   • Debris and moisture   • Contaminants that could reduce the quality of the extracted fluids   • Damages like scratches, dents, cracks, and dings   Corrosion particularly presents a problem for operators, as it may not be easily visible before installation. Contaminants and moisture in the thread may increase the speed of oxidation, leading to a compromised thread profile. Any damaged thread will likely also accelerate the c...

How to Choose the Thrust Stand?

图片
In the past years since we started selling our  drone test stand  technology, we've learned a lot of lessons through trial and error.  If you are familiar with our products, then you know that our  test thrust stands ​ combine thrust and torque measurements with voltage and current to derive the system’s power and efficiency. Perhaps the most obvious concept for such a tool, and the cheapest to build, is a system involving bearings or bushings. What we've learned, however, is that using bearings and bushings has a number of disadvantages: 1. Bearings and bushings cause friction. The random friction error causes significant uncertainty in the measurement (anywhere from 2 to 20% of the measured force). Even if the design looks rigid, there are micro deformations and movements in the system.  2. This leads to hysteresis in the force measurement: the force measured is dependent on the previous force applied. Because of the random nature of fricti...
