Factors that Affect CNC Milling Quality

Wednesday, July 29th, 2009

There are two main factors that control the results of CNC milling: Hardware and software. These factors determine the capability of the milling machine and, ultimately, the quality of work that can be produced.
It is important that the software and hardware of a CNC machine should complement one another. A typical mill is composed of four axes or pivot points that animate the machine head. These pivots make it possible for the machine to rotate, turn, and work on surfaces that are at difficult angles with the head. The more axes in a machine, the more flexible and better it will be.
Software, on the other hand, is what drives the axes for precision machining. CNC stands for computer numerical control, a set of alphanumeric commands that operators can enter on the user interface. These commands are then translated into a computer language called G-Codes.

Safety Tips for CNC Machine Use

Wednesday, July 22nd, 2009

The CNC machine is one of the most versatile machine tools available. It has been widely adopted in big industrial companies. Whether you use them in a small workshop or in a big production plant, it is important that some safety reminders are observed.
First, always work within a buddy system. If that is not possible, make sure that you have one with you when you lift heavy attachments and set up work. This will guarantee that you will not be blindsided by accidents that may result when starting to operate the machine.
Next, observe safety precautions when operating the machine. Use a rug when installing milling cutters, use appropriate rake to remove chips from the work piece, and shut the machine off when you need to make adjustments. These are simple guides to follow but they go a long in keeping you safe in the work place.

How to Choose the Right Milling Machines

Wednesday, July 15th, 2009

There are different types of milling machines that everyone involved in prototyping and production should know. These types do not differ based on power output alone, but in versatility and viability as well for their use in a specific work.
A typical milling machine consists of four axes or pivot points. These axes move either horizontally or vertically and allow the machine to work on different patterns. For added flexibility, there are variations of the machines that have more than four pivots.
A five-axis mill has an additional horizontal pivot for the machine head. The added movement allows the machine to work on the end mill at difficult angles. Additionally, there are mills that have six axes or more that big production plants use to work on difficult operations.
Ultimately, choosing the right machine boils down to its suitability to the required job. To learn more about milling machines and how to get the right one, visit CNCMasters.com or call 1-877-262-8895.

Do More with Your Milling Machine

Saturday, July 11th, 2009

A milling machine is a versatile machine tool that can do even the most detailed engravings. From simple jewelry designs to three-dimensional images, these patterns can be done with the use of an engraving tool that is attached to the machine.
An engraving attachment is typically an air spindle that is mounted by a clamp or a screw to the main axis of the mill. An air spindle can be powered either by a router or an air compressor. The router has a maximum speed of 23,000 revolutions per minute, while the air compressor can power the spindle to up to 40,000 RPM. It is the speed of the spindle that determines the machining efficiency of the attachment. The higher the RPM, the better it is for more detailed jobs.
This special-purpose attachment comes separately from the machine and is specifically designed only for fine machining. For more information about air spindle and other milling machine accessories, visit CNCMasters.com or call 1-877-262-8895.

How to Regulate Cutter Speed of a Machine Milling Vertical

Friday, July 3rd, 2009

A machine milling (vertical) is built for precision cutting. Its head is designed to slide up and down instead of horizontally, giving way to a more secure worktable. In order that the cutting accuracy of a vertical mill is preserved, there are several factors governing cutter speed that operators should look out for.
The type of metal cutter that is screwed to the machine largely influences its speed. Toothed cutters, or positive rakes, are generally run at higher speeds than radial cutters because they cut more freely and are sharper. Also, they receive little resistance from the surface they are working on, allowing the positive rakes to withstand higher speed.
Angle cutters, on the other hand, must be run at lower speeds. It is easier to cut vertically than at an angle. For this reason, the speed of the vertical machine should be adjusted based on the cut to be made.
