CNC turning lathe, Swiss type lathe original manufacturer since 2007.
Starting Out in Woodturning
There are four things you need to become a woodturner: a workspace, the equipment, some timber and the necessary skills.
The workspace
This you probably have already, or you would not be considering taking up the craft. The space you can dedicate to it determines what you can do.
Woodturning takes up quite a lot of space. It can be noisy and dusty, and you need somewhere to store materials and expensive equipment, so the workspace is the first thing to sort out. A proper building, secure, insulated, heated, powered, dry and well lit is ideal. But lots of people do great work in a garden shed or garage.
Whatever you use, if possible, have nothing in the workspace that does not relate to turning - no bicycles, lawnmowers etc. They take up the space that you as a turner will need, and detract from the proper dignity of the craft. And, unless your workspace is very large, try to find somewhere else, protected from the weather, for the wood pile.
The kit
When you start, the bare essentials are:
A lathe with a chuck or at least a faceplate. The lathe should be the most substantial one possible. If you start with a cheap, flimsy machine, you will soon want to replace it. A good used machine is much better than a poor new one.
A grinder for sharpening. Blunt tools will not give you the results you want.
A sharpening jig for gouges. Scrapers and chisels can be sharpened more easily using the grinder's own tool rest.
Some basic turning tools - a good start would be a small roughing gouge, a small spindle gouge, a small bowl gouge, an 18mm skew chisel, a square nose scraper, a round nose scraper and a parting tool
An instructional DVD or book. There are lots of turning gurus producing them.
A face shield and dust mask,
The usual workshop tools - sandpaper, screwdrivers, power drill, handsaw etc.
With these, you can make bowls and vases, boxes, all kinds of spindles, and lots of mess.
Later, you will need a bandsaw, a chainsaw, a drill press, a dust extractor, power sanding equipment, additional turning tools, buffing equipment and lots more. No woodturner ever has all the equipment they would really like. But don't fall into the trap of thinking that the latest advertised tool will make you a turner. The only thing that will do that is lots of practice.
The materials
In the beginning, you can buy readymade turning blanks, but this is the most expensive way to buy wood. It is better to convert small logs and branches to turning blanks yourself, at no cost. You will enjoy turning unseasoned timber. A hammer and splitting wedges can stand in for a bandsaw. You will soon find you have more timber than you can turn, and will need somewhere to store it.
For practice, almost any timber will do, but it is easier to turn wood that is free of large knots, decay and splits, and not too hard. It is a mistake to buy tropical hardwoods when you are starting out. They are beautiful, but harder to turn than species such as oak, which are just as attractive.
The skills
A turner must be able to prepare the wood, sharpen and use the turning tools properly, and come up with pleasing shapes for the finished items.
To develop these abilities, read the books and magazines, study the DVDs, take lessons, join a turning club. If you practice, you will improve. Practice some more. Eventually, practice makes perfect. Learn from people who have gone before, then go your own way to establish your own original style.
There are two options for a turner. Some people use a lathe simply as a means to an end. They use any turning methods that get a result. As scraping tools are comparatively easy, that is what they use. With a little practice, and on suitable timber, scrapers can give excellent results. But they can often leave a very poor surface, which needs heavy sanding and never looks good.
Others set out to learn the more difficult tools - gouges and chisels. They value the craft for its own sake and want to achieve the best possible shape and finish to the work. These tools are more difficult at first, but quicker and more versatile in use, and the effort pays off in the end.

Daily “Clean + Lubricate” as the Baseline
After each shift, remove chips and coolant residue from the fixture surface and collet jaws with a soft cloth or air gun to prevent corrosion and re-clamping errors. Every eight hours, apply a trace of rust preventive oil to spring collets, guide bushings and other moving parts; once a week, add a thin coat of grease to ball-screw nuts and hydraulic cylinder rods to reduce wear. Before any prolonged shutdown, spray anti-rust oil on internal bores and locating faces and wrap them in wax paper or plastic film.
Precision Calibration & Data Closure
Use ring gauges or master bars every month to verify repeatability of the fixture; log results in the MES. If deviation exceeds 0.005 mm, trigger compensation or repair. For quick-change systems (HSK/Capto), check taper contact percentage every six months—target ≥ 80 %. If lower, re-grind or replace.
Spare Parts & Training
Keep minimum stock of jaws, seals and springs to enable replacement within two hours. Hold quarterly on-machine training sessions for operators on correct clamping practices and anomaly recognition to eliminate abusive clamping.
In short, embedding “clean–lubricate–inspect–calibrate” into daily SOP keeps the fixture delivering micron-level accuracy, reduces downtime, and extends overall machine life.
Six preventive measures
Environment control: keep the workshop at a stable temperature and low humidity; exclude dust and corrosive gases to reduce chemical wear on guideways and screws.
Daily checks: remove chips every shift and inspect the lubrication of the spindle, bearings, ball screws and guideways; act on any abnormality immediately.
Preventive lubrication: replace lubricants on schedule and keep the lubrication system unobstructed to minimize fatigue wear.
Accuracy monitoring: use laser interferometers or ball-bar systems monthly to measure geometric errors and compensate for ball-screw backlash or guideway straightness in time.
Electrical health checks: periodically examine cables, relays and cooling fans to prevent hidden aging caused by overheating.
Data monitoring: onboard sensors record spindle current, vibration and temperature; cloud-based analytics predict early bearing or tool failures.
Why prevention matters
• Ensures machining consistency: eliminating micron-level error sources keeps batch dimensions stable and reduces scrap.
• Extends machine life: preventing micro-cracks from growing can prolong overall life by more than 20 %.
• Reduces unplanned downtime: planned maintenance replaces emergency repairs, increasing overall equipment effectiveness (OEE) by 10 % or more.
• Cuts total cost: lower spare-parts inventory, labor and lost-production costs can save tens of thousands of dollars per machine annually.
• Enhances brand reputation: consistent on-time, defect-free deliveries strengthen customer trust and secure future orders.
Optimizing cycle time on turn-mill machining centers is crucial for boosting productivity and reducing costs. It requires a systematic approach addressing machine tools, cutting tools, processes, programming, fixtures, and material flow.
Ensure Geometric Accuracy
Swiss-type lathes process long, slender workpieces with multi-axis synchronization. A bed inclination of only 0.02 mm/m creates a “slope error” along the Z-axis, tilting the tool relative to the part centerline. This results in taper on outer diameters and asymmetric thread profiles. Periodic re-verification and re-leveling restore overall geometric accuracy to factory standards, guaranteeing consistent dimensions during extended production runs.
Extend Guideway and Ball-Screw Life
When the machine is not level, guideways carry uneven loads and lubricant films become discontinuous, accelerating localized wear and causing stick-slip or vibration. After re-leveling with shims or wedges, load distribution evens out, reducing guideway scoring and ball-screw side-loading. Service life typically improves by more than 20 %.
Suppress Thermal Growth and Vibration
A tilted bed leads to asymmetric coolant and lubricant flow, generating thermal gradients. Subsequent expansion further amplifies geometric errors. Re-verifying level, combined with thermal compensation, produces a more uniform temperature rise and reduces scrap caused by thermal drift. Additionally, a level bed raises natural frequencies, cutting chatter amplitude and improving surface finish by half to one full grade.
Chinese-built Swiss-type lathes have moved beyond the “low-cost substitute” label to become the “value leader” for overseas users. On the cost side, machines of comparable specification are priced well below those of traditional leading brands, and ongoing maintenance costs amount to only a fraction, dramatically lowering the entry barrier for small-to-medium job shops in Europe and North America. Lead time is equally compelling: major domestic OEMs can ship standard models within weeks, and special configurations follow shortly thereafter. When urgent orders arise from the electric-vehicle or medical-device sectors, Chinese production lines consistently deliver rapid responses.
Intelligence is on par with top-tier global standards. Machines routinely feature thermal compensation, AI-based tool-life prediction, and cloud-enabled remote diagnostics. Mean time between failures is long, and fully open data interfaces simplify secondary development for end users. Complementing this is a worldwide service network: Chinese manufacturers maintain parts depots and resident field engineers across the Americas, Europe, and Southeast Asia, enabling on-site support often within a single day, whereas legacy brands usually require factory returns measured in weeks.
1. Quick Troubleshooting Steps
Check the clamping pressure: Ensure the pressure plate or collet applies even force; too much or too little pressure will jam the bar. Adjust the pneumatic or hydraulic release mechanism accordingly.
Align the material path: Verify that the bar feeder, guide bushing, and spindle centers are collinear; any offset will cause the bar to twist or wedge.
Inspect belts and rollers: Belts must be tensioned correctly—loose belts slip, over-tight belts bind. Replace worn rollers immediately.
Lubricate moving parts: Clean and grease the eccentric shaft, release cam, and pusher fingers; lack of lubrication is a common cause of seizure.
I. Installation Guidelines for Swiss-Type Lathe Bed
1. Foundation Preparation
Floor Requirements: The Swiss lathe bed must be installed on a solid, level concrete foundation to prevent machining inaccuracies caused by ground settlement or vibration.
Load Capacity: The foundation must support the machine’s weight and dynamic cutting forces to avoid deformation affecting spindle and guide bushing alignment.
Vibration Isolation: If the workshop has vibration sources (e.g., punch presses, forging machines), anti-vibration pads or isolation trenches are recommended to enhance CNC machine stability.
Summary
Ball screws are the physical enablers of Swiss-type lathes across five critical dimensions:
Micron-level positioning for complex micro-structures;
High-speed rigidity supporting synchronized multi-axis cutting;
Active thermal control ensuring batch consistency;
Ultra-wear-resistant design enabling maintenance-free operation for 10+ years.
Their performance defines the precision ceiling of Swiss-type machining – truly "invisible champions" in precision transmission.
