CNC turning lathe, Swiss type lathe original manufacturer since 2007.
Vertical Cnc Milling Machines
With the use of his milling machine, Terry was the primary to accomplish Interchangeable parts in the clock trade. Milling wooden parts was environment friendly in interchangeable parts, however inefficient in high yields. Milling wooden blanks leads to a low yield of parts as a result of the machines single blade would cause lack of gear tooth when the cutter hit parallel grains within the wooden. Terry later invented a spindle slicing machine to mass produce elements in 1807. Other Connecticut clockmakers like James Harrison of Waterbury, Thomas Barnes of Litchfield, and Gideon Roberts of Bristol, also used milling machines to supply their clocks.
They are typically far more powerful than a turret mill, that includes a separate hydraulic motor for integral hydraulic energy feeds in all instructions, and a twenty to fifty horsepower motor. The tables on C-body mills are usually 18' by 68' or bigger, to permit multiple parts to be machined at the similar time. These sensors contact the software before and/or after cutting to measure and examine length.
That is splitting hairs, literally, slicing at about 1/four the width of a human hair; plus, it’s completed with speed. CNC machines’ specs are even more exact, with higher precision achievable in particular purposes. TAICNC can provide the best CNC machine resolution for your business.

However, two requirements that have seen particularly extensive utilization are the Morse #2 and the R8, whose prevalence was pushed by the popularity of the mills built by Bridgeport Machines of Bridgeport, Connecticut. These mills so dominated the marketplace for such a very long time that 'Bridgeport' is just about synonymous with 'manual milling machine'. Most of the machines that Bridgeport made between 1938 and 1965 used a Morse taper #2, and from about 1965 onward most used an R8 taper. They feature a knee and glued spindle head that is only mobile vertically.
For manual milling machines, there may be much less standardization, as a result of a higher plurality of formerly competing standards exist. This tooling is somewhat just like CAT tooling but requires a drawbar within the milling machine. Furthermore, there are a variety of variations with NMTB tooling that make interchangeability troublesome.
The particulars (which are past the scope of this text) have advanced immensely with each passing decade. A milling machine built and used within the store of Gay & Silver (aka Gay, Silver, & Co) in the 1830s was influential as a result of it employed a greater methodology of vertical positioning than earlier machines. For instance, Whitney's machine (the one that Roe thought-about the very first) and others didn't make provision for vertical travel of the knee. This indicates that early excited about milling machines was as manufacturing machines, not toolroom machines. In 1795, Eli Terry started using a milling machine at Plymouth Connecticut in the manufacturing of tall case clocks.
If the tool is brief (and damaged), it must be changed, and the half needs to be checked. Stecker Machine and other high-finish CNC machining outlets embody these sensors as standard in horizontal CNC machine centers. As coated earlier, the program tells the machine what device to make use of, where to place it, how to reduce the part, and so on. Similarly, some horizontal CNC machines handle two pallets using an automatic pallet changer (APC), with one accessible by the operator (for loading, unloading, processing, and so forth.) while the opposite is within the cutting space. CNC machines, because of their design and construction, can cut as precise as zero.001”.

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.
