CNC turning lathe, Swiss type lathe original manufacturer since 2007.
The History Of The Cnc Lathe
Though machinists as soon as had to memorize these commands during their schooling, today many do not because the instructions they use depend upon the type of machine. Additionally, machinists usually input G instructions so typically that they rapidly memorize them.
Many companies rely on a trusted vendor to do their CNC machining providers for them, which works nicely for a lot of businesses throughout a lot of industries. The first production run might be costlier than subsequent ones. Anyone responsible for planning the manufacturing of metallic parts and components would wish to know what benefits they gain using CNC machining. While the type of businesses and merchandise differ, the CNC advantages are clear. Even within this brief listing, you can see how many benefits of CNC machines there are.
The first numerical pc control language was developed by MIT in the late Nineteen Fifties. The earliest model of G-Code was standardized by the Electronic Industries Alliance within the early Nineteen Sixties. Today, the exact, reproducible manufacturing afforded by G-code and similar languages is used in the creation of all kinds of navy and scientific gear and consumer goods. Our consultants can program tasks for small prototype orders or giant bulk orders.
You don't need to know CNC programming to get your machined project done rapidly. Some discuss with the CNC program as G code, though the numbers accompanying G direct solely the motion and performance of the system. The M worth is a part of the program that tells the machine how to do operations outside actions. These examples are only a number of the M values you may even see on a program to run a CNC machine. Some machines require a zero between the M and the quantity while others omit this requirement.
Different letters dictate how the machine moves and numbers set the parameters. While the system known as G code, G is not the only letter used. Other letters have different features in this system, which are usually the identical, no matter a machine's dialect. For occasion, one system could use the generic G1 while another might use G01.
Read on to learn the answer — in addition to some tips for operation within the course of. The first ever CNC machines have been initially developed in the USA round 1940, and it grew really quick as a result of capacity to provide top quality work in massive portions. When designing and building prototypes, it's typically easier to drill, mill, and fit manually with out having to measure setup, and program. Machine Tools should have enough worth (value when it comes to capability and performance, not on the premise of value). Machine Tools should be non-transportable (portability is no matter measurement).
Should they want a reminder, though, most CNC gadgets have an accompanying programming e-book that signifies the exact dialect the equipment requires. Understanding the functions of G code makes reading operation directions easier when you see examples of them. Even if you're not fluent in CNC machine programming, you can nonetheless recognize the significance of the alphanumeric system and the complexity of the program required to create a machined product. Behind each G code are instructions telling a machine how to create variations on its essential functions. Generally, CNC machines have three operations, and the methods show how to adapt those tasks to create a completed product.
Again, figuring out the particular necessities detailed within the machine's coding instructions will help the operator perceive which alphanumeric programs to use. When setting up programs, M codes ought to have one per block of knowledge. These instructions give on and off features to the machine, so having a number of commands in a single group or block could cause program issues. Both G and M codes have specialised makes use of in programming a CNC machine.
The only apparent state of affairs where a CNC machine may not be proper is if you have a small operation that wants easy metallic shapes. In that case, the CNC machine wouldn't confer an enormous cost benefit. Once the computer has loaded in a brand new image for CNC machining, it can pull that mannequin up again and again to provide extra of what it's, which is another of the CNC machine advantages. The technology is designed to attain machining accuracy within .0001. In a CNC lathe, the stock is held in a “chuck” by tightening screws at every end.
Some machines require decimal factors between pieces of knowledge while others permit the operator to omit these. Because these differences in program dialect are so critical in executing the proper program, operators should always know concerning the language of the machine they're utilizing. In the early days of machining, the devices have been numerical controlled, NC. These required playing cards or tape with the codes created by punching holes into a particular order. Before computers turned common, machine outlets often used punch tape to regulate their devices.
The global market was valued at mill axis in multi axis cnc machine and is expected to reach a market value of mill axis by multi axis cnc machine, with a CAGR of mill axis during the forecast period.

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.
