Tschudin proLine High-Performance Centerless Grinding Systems
Flagship proLine grinders (models 400 and 600) excel in high-volume automated production environments. They incorporate a patented fourth CNC Y-axis (Patent US 9,085,059) for vertical regulating wheel positioning alongside a movable W-axis workrest for multi-part grinding.
- High-performance production grinders proLine 400 and heavy-duty proLine 600
- Patented fourth CNC Y-axis (US 9,085,059) for regulating wheel height adjustment
- Heavy-duty capacity for large workpieces up to 250 mm diameter and 500 mm length
- Acoustic emission AE sensors for touch detection and high-speed profiling
Tschudin T35 and HTG Precision Cylindrical Grinding Centers
Tschudin T35 and HTG cylindrical grinding machines deliver ultra-precise finishing of internal and external diameters. Featuring precision headstock spindles with runout below 0.5 um and micro-feed tailstocks, they consistently produce mirror finishes with Ra 0.05 surface roughness.
- Precision external and universal cylindrical grinding machines T35 and HTG
- Roundness accuracy within 0.5 microns and ultra-fine mirror finish Ra 0.05
- Hydrostatic grinding wheel spindle bearings with continuous oil cooling
- Precision carbide centers, collet chucks, steadies, and multi-axis probing
Tschudin Natural Granite Machine Beds and Direct Linear Drives
Tschudin grinder beds and slides are made entirely of solid natural granite, preventing thermal expansion and absorbing process vibrations. Direct linear motor drives on axes X, U, and W guarantee sub-micron feed accuracy without backlash, mechanical ballscrews, or belt wear.
- Solid natural granite machine bed and granite slides for peak thermal rigidity
- Direct linear motor drives eliminating ballscrews, drive belts, and hydraulics
- Outstanding damping characteristics and process stability under heavy duty cycles
- Sealed linear optical scales providing nanometer feedback positioning accuracy
Tschudin Grinding Assemblies, Tooling and FLEX Robotic Automation
Tschudin FLEX automation combines robotic loading portals with in-process gauging systems for lights-out production. The machines grind diverse materials including steel, titanium, carbide, ceramics, and silicon. We provide precision spindles, headstocks, and changeover tooling.
- Flexible FLEX robotic handling cells and automated overhead gantry loaders
- Grinding capability across alloy steels, titanium, carbides, ceramics, and silicon
- Integrated post-process air-gage and optical non-contact inspection stations
- High-precision motorized spindles, diamond form rolls, work centers, and tooling
TSCHUDIN AG High-Precision Centerless Grinding Systems
Swiss manufacturer TSCHUDIN AG from Grenchen has pioneered high-precision CNC centerless grinding machines since 1947. The structural design relies on solid machine beds crafted entirely from 100% natural granite and direct linear motor drives along the X, U, and W axes.
This architecture delivers superior thermal stability, optimal vibration damping, and sub-micron repeatability across challenging production tolerances.
The product lineup features the ultra-compact CUBE 350 grinder engineered for tool changeovers in under five minutes, modular ecoLine 400 and proLine 400 series featuring a patented fourth CNC Y-axis for motorized regulating wheel height control, large-capacity 600 series machines for parts up to 250 mm in diameter, and automated FLEX robotic handling cells.
Engineering Sizing and Turnkey Grinding Automation
Selecting the appropriate Tschudin centerless grinding configuration involves reviewing production volume requirements, roundness tolerances, workpiece dimensions, and material properties.
The grinders process demanding materials including hardened alloy steels, titanium, tungsten carbide, industrial ceramics, germanium, and silicon across automotive, aerospace, medical, and fluid power industries.
SpareX engineering specialists provide production process audits, grinding cycle calculations, non-contact gauging system integration, and dependable international delivery of Swiss grinding machines and matching tooling.
