CNC turning & Milling Services

What Is CNC Turning?

A CNC lathe or turning centre uses computer‑controlled servo motors to move cutting tools along programmed paths while the workpiece rotates. Vertical turning machines support heavy parts by aligning the workpiece’s centre of gravity with the spindle, whereas horizontal lathes are more common and excel at chip evacuation. Basic lathes are two‑axis machines; modern CNC turning centres add a Y‑axis and secondary spindles, enabling three‑, four‑ or five‑axis machining and even integrating milling and drilling operations. Such capabilities underpin precision CNC turning and make it possible to produce complex geometries in a single setup.

CNC Turning Operations

Several standard operations are performed on a CNC turning machine. Facing cuts a flat surface perpendicular to the rotational axis. Straight or taper turning removes material parallel to, or at an angle to, the axis to create cylindrical or conical shapes. Drilling and boring create and enlarge holes, while threading produces external or internal threads. Grooving (parting) forms grooves and cuts the finished part from the bar, and knurling compresses material to add grip. More advanced cycles like tapping, chamfering and radius programs are used to automate repetitive features.

Advantages of CNC Turning

Computer control improves accuracy and repeatability by eliminating manual variability. Turning centres are flexible – when equipped with live tooling or a turning‑milling configuration, they can machine complex parts in one setup. Operator safety is increased because cutting takes place behind guards, and high spindle speeds combined with automated tool changes allow for rapid production. These strengths make CNC turning ideal for both low‑volume custom CNC turning jobs and high‑volume production.

CNC Turning vs. CNC Milling and Hybrid Machines

The core distinction between CNC milling and CNC turning lies in motion: milling uses a rotating cutter on a stationary workpiece, while turning rotates the workpiece against a stationary tool. Milling is best for complex, non‑rotational shapes, pockets and contours; turning excels at rotationally symmetric parts such as bushings, shafts, pulleys and rings. Milling can handle a wider range of materials, whereas turning is most effective on bar stock and less suited to abrasive composites. Production volume also differs: milling is cost‑effective for low‑ to medium‑volume runs, whereas turning offers high‑speed efficiency for mass production.

Hybrid turning–milling machines or mill‑turn centres combine the strengths of both processes. These machines perform turning, milling, drilling and even 3D contouring in a single setup. BACH INDUSTRY AG offers CNC turning & milling services using such equipment to streamline production and reduce cycle times. When searching for “CNC turning and milling services near me,” look for providers who can integrate multiple operations for better efficiency.

Swiss Turning and Specialised Turning Processes

Swiss turning (also called Swiss CNC machining) is a specialised form of turning where the bar stock passes through a guide bushing close to the cutting zone. Conventional turning centres clamp the workpiece at one or both ends; Swiss lathes feed the material through a guide bushing so that machining always occurs near a support point. This minimizes deflection and vibration, allowing for very long, slender components. Swiss machines use movable headstocks and guide bushings, making them ideal for high‑volume production of precision fasteners and medical components. They run on G‑code just like other CNC lathes but often feature multi‑axis capabilities that approach those of a milling centre.

Another niche process is CNC wood turning. Fully automatic wood lathes rotate the workpiece and use tools to perform turning, drilling, sanding, engraving, milling and grooving on wood surfaces. They use digital control and specialized software to generate G‑code, enabling even beginners to achieve accurate machining. These machines fabricate stair columns, baseball bats, pool cues, table legs and other crafts. Multi‑function wood lathes integrate turning, planing, milling and polishing operations into a single machine and illustrate how turning technology extends beyond metals.

Tooling: Chucks, Tool Holders and Inserts

Tool Holders

Tool holders attach cutting tools to the turret and transmit torque from the spindle. Different holders are required for different machining operations and must maintain high geometric accuracy to produce quality parts. Routine maintenance is important because worn tool holders can cause defects and increase costs. Tool holders are grouped into driven tool holders (axial, radial or orientable) and static tool holders. Driven holders rotate tools for milling or drilling; static holders support internal turning (drilling, reaming, tapping, boring, grooving) and external turning (facing, profiling, threading, parting, knurling). Multifunctional double tool holders can mount two tools simultaneously, enhancing efficiency.

Inserts

CNC inserts are small, replaceable cutting edges used in turning and milling. They attach to tool holders so that worn inserts can be replaced without changing the entire holder, improving efficiency. Insert nomenclature codes convey shape, relief angle, tolerance, size, thickness and corner radius. Common insert types include turning inserts, milling inserts, threading inserts, grooving and parting inserts, boring inserts and drilling inserts. Materials range from carbide and cermet to ceramic, cubic boron nitride (CBN) and polycrystalline diamond (PCD). Choosing the right insert depends on workpiece material, cutting parameters, machine stability and desired surface finish. Inserts find applications in industries such as automotive, aerospace, oil and gas and woodworking.

Workholding and Accessories

Reliable workholding is vital. Three‑jaw chucks provide quick centring for round stock, while four‑jaw chucks enable off‑centre turning. Collet chucks offer superior concentricity for small parts. Soft jaws, steady rests, tailstocks and live centres support delicate operations. BACH INDUSTRY AG offers a full range of workholding solutions and can advise on the best configuration for your project.

Programming, Software and Quality Considerations

CNC turning uses G‑codes and M‑codes to control tool movement and machine functions. Standard codes like G00 (rapid positioning), G01 (linear interpolation), G02/G03 (circular interpolation) and M03/M05 (spindle on/off) form the basis of turning programs. Our engineers develop CNC turning programs tailored to customer drawings and can assist with CNC turning program examples for machines using Fanuc or Siemens controls. Simulation and programming software help verify toolpaths, calculate cycle times and optimise feed and speed settings. Quality depends on tolerances, surface finish and runout; our ISO‑certified quality control includes 100 % incoming inspection and functional testing.

Cycle time reduction is achieved through proper tool selection, cutting parameter optimisation and efficient sequencing of operations. Our team uses industry formulas and software to calculate cycle times and recommend improvements. We also support customers with drawing for CNC turning, 3D models and design for manufacturability (DFM) feedback to ensure the best outcome.

Safety, Maintenance and Training

Operating CNC turning machines requires adherence to safety protocols and standard operating procedures. Machine guards protect operators, and proper clamping, tool handling and coolant management minimise accidents. Regular preventive maintenance – including calibration, lubrication, tool inspection and spindle alignment – extends machine life and maintains precision. BACH INDUSTRY AG’s service department offers maintenance support and access to training resources for CNC turning operators, programmers and machinists seeking to advance their careers.
