CNC turning lathe, Swiss type lathe original manufacturer since 2007.
How to view for CNC lathe tool requirements
the nc lathe turning with the tool generally divided into three categories, namely pointed tool, circular turning tool and molding tool. Characterized by straight cutting edge tool generally called pointed tool. This kind of lathe tool tip is composed of rectilinear Lord, vice cutting edge, such as 90 ° internal and external circular turning tool, left, right facing tool, cutting ( Broken) Various cylindrical turning tool and the blade chamfering small and inner hole tool. With this kind of tool machining parts, the first by an independent generalization of parts appearance point or a linear displacement of the main cutting edge, after received it with the other two kinds of cutting tool machining parts summarized the principle of shape is very different. Circular turning tool is more particularly the nc machining tool. Is characterized by a main cutting edge of the blade shape for a roundness error or the line summarized through small circular arc; The circular blade every bit is the turning point of circular arc form, thus, knife site not on the circular arc, and on the arc of circle; Turning radius of circular arc theory has nothing to do with the shape of the processed parts, and demand can be loose judges or determination after the confession. When some pointed tool or molding tool tip has certainly arc shape, also can be used as this kind of tool use. Circular turning tool can be used in turning of internal and external appearance, especially suitable for cutting all kinds of smooth connection ( Concave) The molding surface. Molding tool known as model tool, the generalization of machining parts completely by turning the blade shape and appearance of the standard choice. In the numerical control turning processing, common molding tool has a small radius arc lathe tool, the rectangular slot car knife and threading tool, etc. In the numerical control processing, with or without forming tool should be less as far as possible. In order to satisfied the demand of the initiative in CNC lathe processing, and advances the product processing quality and producing power, save the tooling cost, should use more modularization and standardization of the cutting tool. Numerical control lathe can double as coarse and fine cutting. For rough turning to full depth, large knife, for rough turning tools high strength, good durability; Fine car first is to ensure the machining accuracy, so require cutting tool of high precision and good durability. For cutting tool change time and convenience for knife, should choose machine nipped dao all or many. Using the machine clamp knife to active preparation conditions against the knife. If say to conventional lathe machine clamp knife only a suggestion, so choose in nc lathe machine knife is a requirement. Machine tool blade, production of high precision, the clamping blade method to select more reasonable. Due to the machine clamp cutter with CNC lathe, generally do not add shim adjustment, so the point of high accuracy in production should be ensured. Share of length to diameter larger diameter tool rod, preferably with anti vibration structure. Inner diameter of cooling fluid had better introduce knife body, from head near the volcano. For blade, in most cases should be chosen coated carbide insert. Coating at higher cutting speed, > 100米/分钟) To show its superiority. General lathe cutting speed is generally couldn't get on, so using the carbide insert can not coating. Blade coating increase capital less than one times, and durability when used on nc lathe can increase more than two times. Numerical control lathe with the coating blade can progress in cutting speed, and then can progress processing power. General coating materials are titanium, titanium nitride, carbide and aluminum oxide, etc. , can also be on the same blade with several layers of different materials, become a composite coating. CNC lathes have higher request for the blade of chip breaker groove. High degree of initiative in CNC lathe, cutting, often in a closed environment, so it is difficult to for large chip in the process of turning to artificial treatment. If the chip off badly, it will be wrapped around the head, both may be crushed with the blade, the cutting surface strain. General lathe with carbide insert is generally 2 d chip breaker groove, and the numerical control turning blades often choose 3 d chip breaker groove. 3 d chip breaker groove of the way many, in general in the blade manufactory is already set into several kinds of specifications. It is the common characteristic of chip breaker performance is good, wide scale of chip breaker. About raw material parts in detail, after cutting parameter set, to pay more attention to choose the right blade groove type. Choose can make some theory in the process of discussion, but more important is real cutting experiment was carried out. On some occasions, can also according to the existing modified blade groove cutting parameters. For blade with high durability and it is beyond doubt. CNC lathe also requires the blade durability good consistency, so that the use of cutting tool life function. In the use of cutting tool life is dealt with, the blade durability setting standards is to put the minimum durability of blade blade as basis. In this case, the consistency of the blade durability and is more important than the average days. As to the accuracy, the same required accuracy good consistency between the blades.

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.
