Sliding-head machines for machining medical components

Medical devices have and are undergoing rapid change, generating pressure on the manufacture of components. Even some of the more basic parts such as screws have evolved as regards type, design, quality demands and delivery demands.

In the machining of medical parts, batches are generally smaller, with shorter delivery times and more demanding materials and designs. The sliding-head machine is advantageous, efficient and flexible for this area but how well optimized are the machining operations, how many operations are needed and how long are the stoppages? Today there are new solutions for titanium machining and quick-change tooling concepts that make a huge difference to performance and results.
In the machining of medical parts, batches are generally smaller, with shorter delivery times and more demanding materials and designs. The sliding-head machine is advantageous, efficient and flexible for this area but how well optimized are the machining operations, how many operations are needed and how long are the stoppages? Today there are new solutions for titanium machining and quick-change tooling concepts that make a huge difference to performance and results.

In response, machinery, methods and tooling are developing to meet demands from a growing industry. The sliding-head machine provides an advantageous basis for very efficient machining – where parts are small but the differences in degree of utilization is large.

A difference to a great extent determined by tooling and methods application
As far as small-part machining goes, making medical parts is often different. Batches are generally smaller, with shorter delivery times, materials more demanding and designs. Tooling and methods need to be closely suited to features to achieve satisfactory results. Long, slender screws in titanium is one example. Complete solutions are needed with the right tool and process know-how which needs to include measures ranging from the cutting edge to the way tools are held and changed.

To plan carefully
These solutions are especially critical in achieving high efficiency of the multi-functional sliding-head machine. Here it is vital to prioritize not only the cutting process but also the non-cutting part of the cycle time to maximize output during the available production time. How long does the in-cut machining take, how many operations have to be involved and how long to change tools?

Three typical kind of parts
In a further issue we will describes three typical medical components made on sliding-head machines with examples of machining operations and modern solutions that optimizes machining and make a marked difference to productivity:

  • dental screws
  • bone screws
  • tulip heads
With bone screws being long, slender titanium parts, the thread-making process needs to be especially secure and efficient to result in a –high-quality part. Thread whirling is ideal, being a productive, reliable process that avoids bending and vibration tendencies. Correct selection of tools, cutting data, programming and setting of the process is important to achieve optimum results but the productivity is superior.
