Case Study of CNC Turning Tread Shafts

The case study of CNC turning tread shafts presents an interesting set of challenges and opportunities. Compared with custom milled parts, this process is less expensive and complex. Furthermore, it is easier to assemble. Let’s explore some of these challenges and opportunities. During the Second World War, Whitworth thread diameters were reduced to save metal. Although these sizes are now available, they were once extremely scarce and difficult to source. However, through subcontracting activities, arduino guides, and Facebook groups for steam-driven vehicles, Mr Swaffield discovered a business opportunity in this area.

Less complex than drilling a hole

CNC turning is a highly accurate process that is less complex than drilling a hole. It has the added benefit of being able to achieve high tolerances. Drilling is a process whereby the cutting tool is driven perpendicular to the surface of the workpiece. This process can be very expensive, as it can require multiple passes. Fortunately, CNC turning allows the user to set their own tolerances and reduces the time spent changing tools.

Less expensive than milling

Turning parts are less expensive than their milled counterparts, and they can be more precise. For one thing, milled parts are difficult to turn, especially if they have deep grooves and pockets. Long, thin shafts can also be tricky. Custom milled parts usually require additional machining steps to remove broken edges, while turned parts do not. To deburr a milled part, some machining providers use abrasive wheels, tumble the part in small rocks, or blast the part with glass beads or walnut shell. Each method has its advantages and disadvantages, and may change the final look of your part.

Milling and CNC turning are similar in that they both use rotating cutting tools and work from a design program. The difference between milling and CNC turning is that the former uses computer numerical control (CNC) technology to automate the process. The CNC control system automatically determines which operation should come first. CNC milling and turning are highly automated processes, meaning the operator can concentrate on troubleshooting and loading the next batch of parts.

Easy to assemble

CNC turning tread shafts are easy to assemble, and there are a number of ways to make them. The most common way is to use a Trantorque design. This design uses a three-piece bushing with an inner contracting collar and an outer expanding sleeve. The outer sleeve expands as the nut is tightened, providing holding forces to the shaft.
