5 Axis CNC Precision machining, milling and turning:
cnc 5 axis chart
5 axis cnc machining is unique in its ability to effectively process part sizes and shapes with essentially infinite possibilities. Like 3 axis machines, the cutting tool of a 5-axis precision machining center moves across the X, Y, and Z linear axes, but also rotates on the A and B axes – allowing the cutting tool to approach components from any direction.

Curves are as easy to cut as straight lines, complex 3-D structures are relatively easy to produce, and the number of steps that required human action have been dramatically reduced thus saving time in money in cnc shop. With the increased automation of manufacturing processes with precision 5 axis CNC machining, considerable improvements in consistency and quality have been achieved in modern machine shops.

5 Axis Machining demands a machinist to think out the box. It might be difficult to apply cnc machining into true 5 axis motion but we do exactly that!



5 axis machining shop Haas UMC 750 review: We all know about vertical and horizontal 5 axis machining centers, but the newest innovation from Haas Automation is their Universal Machining Center known as the UMC-750. The machine is a 5-axis 40-taper vertical machining center with an integrated dual-axis trunnion table with travels of 30″ x 20″ x 20 suited for most precision cnc machine shops

The UMC-750’s dual-axis trunnion table can position parts to nearly any angle for 5-axis (3+2) machining, or provide full simultaneous 5-axis motion for contouring and complex cnc machining. The trunnion provides +110 and -35 degrees of tilt and 360 degrees of rotation for excellent tool clearance and large part capacity, and the 630 x 500 mm table features standard T-slots and a precision pilot bore for fixturing.

Materials and Metals in our cnc machine shop:
We use many different metals such as hastelloy that possesses excellent mechanical strength, especially at high temperatures, and is both highly resistant to corrosion and oxidation. Molybdenum has the low thermal expansion, similar to that of silicon, makes it a frequently used material in the electronics industry for semiconductor supports and glass sealing. On the other hand, tungsten has the highest melting point and the highest tensile strength. It is extremely durable. Pure tungsten is too difficult to work with, so tungsten that is used for industrial applications - and in jewelry - is compounded into its carbide form.

5 axis machining is used in wide range of industries to manufacture components with ultra-precision and fast manufacturing times: Satellites, Aircraft, Aerospace, Optical and Medical Equipment.

Top Androit machinist apps You can use in cnc shop: (You may also check other android applications helping in 5 axis precision machining)

machinist app
Machinist Buddy Free
Machinist Buddy is a tool for a cnc machinist and engineers to handle a lot of the tedious day to day calculations in the shop with 5 axis machines. The user interface has been completely overhauled and is now greatly organized. The Full version includes much more functionality. The newest and best version of the app has been released. Version 14(4.0) has been a great success.

With the inclusion of swiping, tabs, references, and many more functions. The Full version is still most definitely the way too go. Here’s a link to the app


CNC Troubleshooting Fanuc Axis
This is the go to app to troubleshoot issues in your CNC Machines, PLC or Robots with FANUC Drives. Do you know that it costs an average of $5,000 for a service engineer to walk into your facility? Using this knowledge base, even a person with minimal CNC troubleshooting experience can troubleshoot on his own without waiting for a service engineer. The step by step flowcharts included in this app will walk you through to troubleshoot your problem with 3 or 5 axis cnc machine. All you have to do is answer YES or NO. If you don’t know the answer, you have help in the form text that can help you answer the question. The idea is to narrow it down to one or two faulty parts.
Sometimes buying two parts is cheaper and faster than getting a CNC engineer to visit your shop. There are alarm and symptom approaches to troubleshooting and procedures on maintenance and safety. A link to this app.
