CNC turning lathe, Swiss type lathe original manufacturer since 2007.
The layout of the CNC lathe tool rest
the level of the numerical control lathe bed of good manufacturability, easy to guide the processing. Horizontal lathe bed with knife slimming level equipment can progress rate of movement of the tool post, generally can be used for the layout of the large or small precision CNC lathe numerical control lathe. Horizontal lathe bed bottom, however, the space is little, which causes the difficulty in chip removal. Look from structural dimension, tool carrier placed makes slide transverse dimension is longer, thus make the structure of the machine tool width dimension. Horizontal lathe bed with skewed placed skateboard and equipment layout of skewed type guide rail protective cover, with horizontal lathe bed manufacturability good characteristics. The level of the scale of the machine tool width equipment skateboarding, and chip removal is very convenient. Horizontal lathe bed with skewed placed skateboard and slant bed equipped with inclined slide layout was widespread use by small and medium-sized CNC lathe. This is due to the two kinds of layout of chip removal easy, chip won't pile up on the guide rail, also facilitate equipment active chip removal device; End manipulator operation is convenient, easy to machine to single active; Machine cover an area of an area small, appearance is concise, beautiful, easy to closed end protection. Explanation for everybody below the layout of the CNC lathe tool post: CNC lathe tool rest is an important part of the machine tool, cutting tool carrier is used for clamping tool, thus, it directly affect the cutting performance of machine tool structure and cutting power, surely in extent, head structure and performance reflects the level of planning and production CNC lathe. Followed the development of numerical control lathe tool post structure mode innovation, but in general can be roughly divided into two categories, namely the knife type tool rest and turret head. Some turning center still choose active in knife knife library of equipment. Row of knife rest is commonly used in small numerical control lathe, each kind of cutting tools is put and clamping on the movable slide, can take the initiative to end when positioning tool changer. Turret head also called tower or knife sets, there are vertical and horizontal structure of two kinds of ways. With tool active positioning equipment, through the rotation of the turret head end, dividing and positioning to active tool change machine. Degree of turret head should be accurate and reliable positioning, high repeat positioning accuracy, transfer speed, clamping cut sex good, to ensure the high precision and high power of CNC lathe. Some turret head end not only can active positioning, will also be able to transfer power. At present, more than two coordinates linkage lathe with 12 station turret tool post, also have choose 6, 8, 10 station turret head. The layout of the turret head on the machine tool has two ways: one is used for processing plate parts turret head, the rotating shaft is perpendicular to the main shaft; Another kind is used for manufacturing axial and plate parts turret head, the rotating shaft is parallel to the axis. Four coordinate control Ji CNC lathe bed equipment has two independent board and turret tool post, so called double four-axis CNC lathe. Meanwhile, each head cutting feeding is controlled, thus, two different parts of the tool rest can at the same time cutting the same workpiece, expanding the processing scope, and improved the processing power. Four-axis CNC lathe has a complex structure and demand equipment specialized CNC system, the end of two independent manipulation of the tool post, suitable for processing complicated shape, such as crankshaft, aircraft parts batch larger parts.

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.
