A roughing grade is very tough and will run at slower surface speed but withstands intermittent cuts well. However, your roughing may be very different to someone else’s roughing.  For example, a turner on a VTL turning large stainless steel castings will be taking 5mm+ depth of cut, whereas a turner on a smaller lathe will be roughing with much smaller depths of cut.

Grade 5 titanium, also known as Ti6Al4V, is a popular choice for CNC machining due to its excellent strength-to-weight ratio, high corrosion resistance, and good machinability. However, other grades such as Grade 2 and Grade 9 can also be suitable depending on the specific requirements of the part. Ultimately, the selection of the best titanium alloy for CNC machining will depend on factors such as the part’s size, complexity, strength requirements, and corrosion resistance needs.

It is also commonly used in the production of high-performance alloys, such as titanium alloys, which have superior strength-to-weight ratios compared to other metals.

Generally, titanium is a more expensive material than many other metals, which can contribute to the higher cost of CNC machining titanium parts. Additionally, the challenges associated with machining titanium, such as the wear and tear on tools, can also increase the cost.

Grade 5 Titanium, or Ti6Al4V, is a popular titanium alloy for CNC machining due to its exceptional combination of properties. With 6% aluminum, 4% vanadium, and 90% titanium, it has a density of 4.43 g/cm³ and a tensile strength of 880 MPa, making it one of the strongest titanium alloys available.

For roughing applications, you would usually opt for a 0.8mm or 1.2mm radius depending on your machine’s horsepower and the depth of cut you plan on taking.

Top Tip for Finishing: Use a finishing chip breaker with a small enough radius to get the chip breaker working. This is a common mistake engineers make: trying to finish with an 0.8mm rad with a medium chip breaker taking a 0.1mm cut. This is just going to rub on the work piece and cause poor surface finish. Furthermore, on stainless steel you will just put heat into the job and make it unmachinable.
