Euroturn 6/20

Euroturn 6/20 vs Index MS 16 (16 mm max, larger brand) vs Tornos Sigma 20 (20 mm max, larger brand): The Index MS 16 is actually a 16 mm machine — the Euroturn 6/20 provides 4 mm additional bar capacity, accessing a broader range of components. The Tornos Sigma 20 is the most direct comparison at 20 mm. Key differences: (1) Tornos has a larger global service network, particularly valuable outside Europe; (2) Euroturn's independent German manufacturing may offer pricing advantages in certain configurations; (3) Tornos has deeper market penetration in Swiss watchmaking and precision medical parts. For European automotive and fluid power manufacturers, the Euroturn 6/20 is a credible alternative to both, particularly where local German service is valued. For precision medical and watchmaking, Tornos Sigma 20's established application expertise is a meaningful differentiator.

In the European automotive supply chain, the Euroturn 6/20 is used for: (1) Fuel system connectors — quick-connect fitting bodies, fuel line end fittings, and evaporative emission system ports in nylon-reinforced and steel configurations; (2) Cooling system components — bleed screw bodies, expansion tank cap cores, and thermostat housing inserts in brass and aluminum; (3) Brake system fittings — brake line unions, ABS sensor housings, and caliper bleed nipples in steel and brass; (4) EGR system fittings — exhaust gas recirculation valve seat inserts and pipe connector bodies in stainless; (5) Transmission components — sensor body blanks, solenoid valve housings, and pilot valves in alloy steel. Bar material is typically free-machining steel (11SMnPb30 or 11SMnPb37), brass (CW614N), and stainless (303 or 316L) depending on application.

Euroturn 6/20 changeover procedure for a complete job change: (1) Call up new part program from control memory or DNC transfer — 15-30 minutes including review; (2) Remove and replace tooling at all 6 stations — typically 12-18 tools, 2-3 hours depending on live tooling configuration; (3) Set tool length offsets for all new tools using preset tool lengths or on-machine touch setting; (4) Change bar feed collet, guide bush, and bar stop for new bar diameter — 30-45 minutes; (5) Load new bar material to feeder; (6) Run 5-10 first-off parts; (7) Measure all critical dimensions and adjust offsets to print. Total time: 4-7 hours for a complete changeover to a different part family and diameter. For repeat jobs with same bar diameter and similar tooling layout, time reduces to 2-4 hours. This compares favorably to cam multi-spindle changeover times of 1-3 days.

The Euroturn 6/20 uses a flood coolant system with chip conveyor and coolant recirculation. Standard specifications: coolant flow rate 80-120 L/min at 5-8 bar (standard), with optional high-pressure coolant upgrade to 70+ bar for through-tool drilling applications; stainless steel coolant tank with magnetic chip separator and paper band filter for fine chip removal; chip conveyor delivering chips to external chip bin; coolant concentration monitoring and automatic top-up in some configurations. For stainless steel and titanium machining, high-pressure through-tool coolant (70-100 bar) is strongly recommended for hole-drilling operations to prevent chip packing and drill breakage. For brass and free-machining steel (the most common 6/20 materials), standard 5-8 bar flood coolant is adequate for most operations. Coolant type: typically semi-synthetic or synthetic metalworking fluid at 5-8% concentration.

The Euroturn 6/20 uses a combination of gravity chute and optional conveyor belt for parts unloading. When parts are parted off at the cutoff station, they fall into a parts catcher chute that directs them to a parts bin or conveyor. Options include: (1) Standard gravity chute to parts bin — adequate for robust parts where impact is not a concern; (2) Conveyor belt with soft landing zone for precision or delicate parts (watch components, medical parts) requiring gentle handling; (3) Parts catcher with separate bin for back-working attachment parts vs. main spindle production; (4) Integration with in-process gauging systems where every part is measured before depositing in the production bin. For high-value medical or precision instrument components, a soft-landing conveyor with pneumatic part transfer is recommended to prevent surface marking or dimensional distortion on fragile micro-parts.
