Guides For CNC Turning Machines That Can Help To Use Them At Home
Turning machines are tools for cutting with non rotary bit moving linearly while the material rotates. Their movement axes are either a straight line, with curves or with angles but essentially are linear and intended for external surfaces. If applied on internal surfaces, the process is called boring and together they are categorized as lathing.
These process were traditionally done manually and has an operator for supervising them and the recent ones would be automated and does not need supervision. The latter is done using CNC turning machines in CT and computer programs are controlling the operation. Their early versions have created geometric figures which are complex though their recent creation is rarely done.
Turning processes are usually executed by lathe with four varying types like external grooving, profiling, taper and straight. These can produce different shapes of workpiece such as grooved, curved, conical and straight. If you have a small machine at home and want to try this process for your personal projects then follow these guides that could help you.
Buy high quality carbide cutters from trusted brands to achieve better results rather than buying inexpensive ones with no names. They tend to break easily specially when used with metals resulting to more expenses for constant replacements. You will not need the most expensive ones but those from a reputable brand with favorable reviews.
Buy calculators for speeds and feeds, or cutting speed and feed rate respectively, to make sure they are set with precision. The latter is velocity of the tools when being advanced along and the former is speed difference of workpiece surface and cutter. Tough materials need them precised correctly and calibrating them without calculators is not possible.
Determine the correct depth and width of cut which is important in avoiding tool deflection or its bending that causes accuracy problems. This would add to chipload, or the removed material thickness, and largely contributes to early breakage. The deflection reduces CNC accuracy also because the instrument will not be where the code expects its exact location is.
Small machines commonly have issues of easily moving around when they work with powerful force because they lack weight required. This is unlike larger ones that can handle jobs with high power like cutting stainless steel. Reduced the force used in your cuts according to their size so they would stabilize when using them.
Some machines that have consumer grades possess cheap toolholders that will not endure pressures coming from tough materials. Those toolholders are a steel bar with shanks on one side clamped into the machine and other side having clam for holding the interchangeable tools. If your cutters break often, you should upgrade the toolholders or reduce the chipload.
Be sure of using coolant which could reduce some issues related with cutting some tough materials like heat retention or material hardening. Therefore, using one when you work with difficult materials would be a good idea. These are some guides that could help you and if you have more questions, visit your local shops or let them work on those your machine cannot handle.
