What Does 2021 Hold for Swiss Precision CNC Manufacturing?

2020 was a strange and difficult year for individuals and business.  In precision manufacturing, the COVID-19 pandemic has brought on new challenges and resulted in advances in manufacturing. Workforce reductions and restriction have placed greater emphasis on computer-aided manufacturing and automation.  While some aspects of precision manufacturing such as planning, engineering and programming can carry on remotely, Swiss screw machine manufacturing must occur at the facilities like Sheldon Precision where the battery of Swiss screw machines (single spindle Swiss screw machines as well CNC Swiss screw machines like Escomatic) are located.

Skilled CNC machine operators  and CNC programmers are still in demand and as the economy in North American and around the world starts on the path to recovery. manufacturing will rise. Manufactures like Sheldon Precision are leveraging automation, machines, computer software and skilled operators and engineers to maintain quality and output.

What advances and trends are expected in 2021? Here are four CNC trends to watch for next year.

  1. Manufacturing as a service will continue to gain popularity 

Manufacturing as a service (MaaS) has found its way into the CNC industry over the last few years and its popularity will only increase moving forward.  MaaS uses networked resources to accomplish manufacturing tasks.  CNC machines are located in a central location and the cost of maintenance and operation is spread across subscribers.  MaaS gives companies added agility, productivity and cost savings through reduced labor expenses.  Since there has been a large fallout from the COVID-19 pandemic in 2020, companies will start to embrace a new network of supply chains by using MaaS.  

2.   The IIOT will dominate emerging technology 

The industrial internet of things (IIoT) allows networked CNC machines to communicate with one another without needing a human operator behind the scenes.  IoT has recently become  part of the CNC machining industry.  By using IIoT, companies can make manufacturing quicker, safer and produce higher quality products.  The level of process automation in 2021 will rise greatly due to the manufacturing industry trying to find new ways to increase efficiency and reduce waste.  

3.   The Use of 6-axis Machining will expand rapidly 

The 6-axis CNC milling machine first came on to the scene in 2019.  For many years before this machine was released, the 3-axis machine was the machine everyone chose to use.  Recently, the 5-axis machine has become popular due to the seamless rotations around the X and Y axes.  Now, the 6-axis allows an additional rotation around the Z axis leading to faster cut times.  

4.  An increased focus on waste product reduction 

Raw materials have been a precious resources for manufacturing and in 2021 there will be increased attention to wise materials usage.  One new strategy is to create scale models of components using 3D printing methods rather than trial and error design on CNC equipment.  

Sheldon Precision continues to focus on quality and continuous improvement in our manufacturing resources and process. As new machines and technology in precision Swiss manufacturing emerge, Sheldon Precision will leverage these resources for customers in all industries including medical device component manufacturing, defense systems component manufacturing and many others.  Contact us today for your custom quote https://sheldonprecision.com/request-a-quote/

What is Swiss Type Machining?

 Manufacturers in many industries are recognizing the benefits of Swiss style tools such as cutting costs and being more efficient. 

A number of industries are starting to now use Swiss type machining.  The durable goods industry has discovered that Swiss-lathes are highly beneficial and help improve output.   The electronics and medical industries are becoming more reliant on Swiss lathes and other Swiss machining tools. 

There are a lot of Swiss machining tools on the market, all which have major benefits.  The Swiss style lathe has a turning center that allows the part to move in the Z-axis, while the tool is stationary.  Conventional CNC lathes have the part stationary while the tool moves.  One of the major differences is the holding mechanism is not exposed to the bed or the tooling. 

Here are some of the other benefits of using a Swiss type machine:

1. Better Support for all Stock Material

This is the greatest benefit of Swiss style lathes.  It provides much better support than a traditional lathe. There should be fewer defective parts due to the reduced risk of the support material moving.  If the material is not adequately supported, an uneven cut will result.  This is especially a problem if you are trying to create a thread for any cylindrical object.  The threads will be useless if the depth of the cut is not uniform across the entire length of the threaded area.

2. Superior Tolerance

Swiss style lathes use the process called guide brushing which enhances rigidity and leads to a higher tolerance level. 

3. Ability to Work with Smaller Parts

Standard lathes are not ideal when working with small parts.  You would need to use more expensive machining processes such as making laser cuts.  Swiss style lathes are able to handle very small parts and are often the most affordable option to make cuts. 

The latest Swiss lathes are fully CNC operated and often have additional capacities such as milling and laser cutting.  Not only can both tuning and milling be performed on a Swiss machine but they can be performed simultaneously.  A Swiss lathe allows for the machining of intricate designs utilizing drilling, knurling and other unique processes on a single machine. 

Manufacturers with Swiss machines can produce long runs of small, complex parts faster and cheaper than traditional lathes.  This is an ideal addition to boost efficiency, productivity and capabilities in your business.  Swiss lathes are great for high production work, often with cycle times under a minute.  An Escomatic machine is an ideal Swiss type screw machine for turning accurate parts produced in high volume with diameters up to 5mm.  Parts machined on a Swiss lathe are often found in the electronics, medical device and defense industry.

Understanding CNC Swiss Screw Machines and Their Functions

CNC Swiss type automatic lathes are now more powerful than ever.  They have fast cycle times and flexibility that have made them the standard and number one machine used in precision, high production applications.  Swiss machines were always preferred for long, slender turned parts, now they are widely used for small, complex parts – even pieces that have no turned surfaces. 

In a conventional lathe that has a fixed headstock, the workpiece is held in a collet and extends into the machine enclosure as a cantilever or can be supported on the end by the tailstock.  A distinguishing feature of the Swiss machine is that the headstock moves.  Bar stock passes through a chucking collet in the headstock, which clamps onto it.  The bar emerges into the tooling area through a guide bushing, which locates the bar radially during machining.  The headstock moves precisely back and forth in the z-direction, taking the bar with it. 

The turning tools, carried on gang slides contact the bar very close to the guide bushing, usually within 1 mm to 3 mm.  The motion of the bar provides the feed for the cutting action.  Gang slides carry holders for fixed single-point or other tools and may support live tooling.  Many machines have a secondary spindle, back working tool stations and one or more turrets that carry more tools. 

The guide bushing supports the workpiece to maintain precision throughout the machining of the workpiece.  A physical object subjected to a force will deflect.  On a conventional lathe, if the cutting forces cause too great of a deflection, the accuracy of the cut will suffer.  When you turn parts on a conventional lathe with a length-to-diameter ratio of greater than 3:1 you should use a tailstock to prevent excessive deflection.  For any ratio greater than 6:1, you would use a steady rest or follow rest to support the middle of the part.  If you hold a workpiece securely at one end and push sideways on the unsupported end, the workpiece bends a little bit.  If you are pushing with the same force on a longer workpiece it will bend more.  The deflection for a given force increases as the cube of distance from the support to the force is twice as long with eight times the deflection.  In a Swiss machine, the guide bushing supports the workpiece so close to the tools that the deflection due to cutting forces are close to zero.  You are able to make heavy cuts and still maintain precise dimensions on the part.

Some advantages of CNC Swiss Machines come from both the guide bushing and the geometry and mechanics in the tool zone

  • – Depending on the machine, there may be room for 20 tools or more in the tool zone
  • – Chip-to-chip time from one tool to the next cab be one second or less
  • – A single heavy cut often removes all the necessary material
  • – Surface finish can be excellent, often eliminates the need for grinding
  • – Machines with sub-spindles allows working on the back side of the part
  • – A Swiss machine can make complex parts using simultaneous operations, three or four tools can cut at the same time
  • – Most secondary operations are eliminated, since a Swiss machine can mill, drill, ream, saw and do other operations within the machine
  • – The Swiss machine can run for hours unattended after the machine is set up and the bar stock is placed in the bar loader

Medical devices are often manufactured on Swiss machines.  The United States is the world’s largest medical device market and these devices help improve surgical outcomes with advanced technologies to help make a difference in people’s lives.  Medical components are highly complex pieces that are critical to the safe operation of the device.  Medical devices include parts such as surgical needles, screws and lock plates.  Medical component specialist are experts in these high precision machine parts and can identify when tighter that necessary tolerances have been specified for these parts.

If you are running small, complex parts on your CNC lathes you might be better off using a Swiss Machine so that the lathe can be saved for larger parts.  Many new Swiss machines already run Muti-function fixed head lathes that mill and drill in addition to turning.  The controls on Swiss machines are familiar to most users and offline programming software helps users generate programs tailored to Swiss machines.  By using a Swiss machine in your operations, you can help reduce cycle times and eliminate secondaries for parts on the smaller end.  If you are looking into using Swiss machines to manufacture one of your products contact us today at https://sheldonprecision.com/request-a-quote/
