CNC turning lathe, Swiss type lathe original manufacturer since 2007.
Cnc Machining Centers & Swiss Type Lathes
Often often known as the center of a machine software, the principle spindle consists of a spindle assembly and the spindle drive system. These are a number of the shifting elements of the CNC machine device, they usually include motors, gears, and the chuck (extra on it later). The C-axis drive which helps to position the fabric may also be assembled together with the spindle. Mini-lathes and micro-lathes are miniature variations of a common-purpose center lathe (engine lathe).
This feedscrew may be engaged, by way of a gear prepare, to the feed shaft (talked about previously) to offer automated 'power feed' motion to the cross-slide. On most lathes, only one course could be engaged at a time as an interlock mechanism will shut out the second gear practice.
Usually, the compound rest has a protractor marked in its base (2b), enabling the operator to regulate its axis to precise angles. The cross-slide rides on the carriage and has a feedscrew which travels at proper angles to the principle spindle axis. This permits facing operations to be carried out, and the depth of reduce to be adjusted.
A CNC lathe machine is generally used to perform / produce exact spherical shapes with both an Outer Diameter (OD), and an Inner Diameter (ID). Practically every kind of structures could be machined with this machine device, relying on their needs in numerous industries. Hwacheon incorporates highly rigid strong field guides on all axes for its Hi-TECH line of machines to chop down time between processes and to enhance machining precision. Separate from the main spindle as an choice, the sub-spindle works in sync with the main spindle to finish the first and second slicing operation in a CNC lathe. When named as a second spindle, the mechanism has the same capability and energy as the main spindle.
The compound rest (or top slide) is often the place the software post is mounted. It offers a smaller amount of movement (less than the cross-slide) alongside its axis via another feedscrew. The compound relaxation axis may be adjusted independently of the carriage or cross-slide. It is used for turning tapers, to regulate depth of minimize when screwcutting or precision dealing with, or to obtain finer feeds (under manual control) than the feed shaft permits.
They sometimes have swings within the vary of 3 to 7 in (seventy six to 178 mm) diameter (in other words, 1.5 to 3.5 in (38 to 89 mm) radius). They are small and reasonably priced lathes for the house workshop or MRO store. The same advantages and drawbacks apply to these machines as defined earlier relating to three-in-1 machines. The device bit is mounted within the toolpost which may be of the American lantern style, conventional four-sided sq. fashion, or a quick-change fashion such as the multifix arrangement pictured. Interchangeable device holders allow all instruments to be preset to a middle top that doesn't change, even if the holder is removed from the machine.
The result's a complete and even complicated part manufacturing process, eliminating the necessity to transfer the part to another machine for a second operation e.g. to a CNC milling machine or CNC machining centre. CNC Lathes are generally used in industries corresponding to oil & fuel, automotive, aerospace, medical, electronics, mining, power plant, metal & paper mills, and ship building, simply to call a number of.
When a lathe is installed, the first step is to stage it, which refers to creating certain the bed isn't twisted or bowed. There is not any need to make the machine exactly horizontal, but it should be totally untwisted to realize accurate slicing geometry. A precision degree is a useful tool for identifying and eradicating any twist.
The importance of cnc service has increased as mill axis have become a must in our daily life.

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.
