CNC Machining And CNC Milling Machines
Computer Numerical Control (CNC) machining is a common technique that is contemporarily utilized in the metalworking industry. As opposed to conventional machines, CNC machining makes use of computerized systems which facilitate superior output in complicated shapes for a range of materials. A renowned example is the CNC milling machine.
Why CNC machining stands out?
Previous machines which were known as numerical control machines (NC) located their positions via G-codes. These G-codes were manipulated manually by the user unlike in CNC machining whereby this task is computerized. In the most recent versions known as the parametric program, logical commands have been fixed in a manner that they can work together with these G-codes. This modified version allows users to regulate and manipulate system parameters effortlessly.
Benefits of using CNC machines:
The improvement in technology used in the manufacturing of these machines has brought about a number of benefits.
These include the following:
- There is improved speed, accuracy, productivity and efficiency of tasks
- They significantly reduce the incidents of accidents since computerized systems minimize the contact between the tools and the user. This makes the metalworking process a more comfortable undertaking.
CNC Milling Machines:
CNC milling machines function by using a computerized system to transmit signals to a stepper motor controller. This system instructs the stepper motor on the direction to follow and the number of steps it is supposed to take. The motor is linked to the drive mechanism of the mill in the X, Y and Z axes. Some CNC milling machines are known to utilize a servo motor as a replacement for the stepper motor. They have below mentioned advantages:
- Metals can be cut at higher rates
- Servo motors have a feedback loop which enables the machine to accurately resume to its initial position.
How to find the best CNC milling machines?
These machines have become essential in very many facets of life especially in the running of our businesses. The purchasing of this machines entail that you have to find the right kind of supplier or dealer. The following are tips to assist you in identifying the most ideal place where the machines can be obtained from:
- Check the quality of the milling machine. Visit online forums to get information on the available brands in the market and the most reliable brands according to customer reviews.
- Choose a supplier or dealer with professional staff and highly skilled personnel to repair your milling machine if it breaks down
- If you are looking for a cost cutting option, some suppliers deal with second hand milling machines so, pursue such options.
Maintaining your CNC milling machine:
Once you have your milling machine purchased, some important tips can be followed to keep it in top condition. These machines are usually maintained by a set up process. This includes the below procedures:
- Wipe the table to the T-holder to keep it free it from fragments and rust.
- Place its vise down and tighten it with bolts. Straighten the vices using an indicator
- Place every tool into collects and ensure they are safely locked.
- Set the collets into the changer of the tool as per to the manual of the machine.
- Confirm if the machine 'knows' where it ought to stop. This is to guarantee that the machine makes an accurate cut. - Set the spindle on the zero point then ignite the machine again on the X and Y axes
- Next, locate the Z point by lowering the spindle to the top of material. This point will be used as a reference in cutting other materials.
This simple setting up process guarantees that the CNC machining machine works efficiently for years on end. This process is to be repeated whenever the machine is heavily used.

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.
