The Sheffield TF1004 is a CNC universal cylindrical grinder built for precision OD and ID grinding operations. Manufactured by Sheffield, a long-established name in British precision grinding, the TF series was designed for shops demanding tight-tolerance work on shafts, pins, bearing journals, rollers, spindles, and other cylindrical components.

The universal configuration features a swivel wheelhead and swivel headstock, enabling compound angle setups for straight grinding, taper grinding, shoulder grinding, and internal bore work in a single machine.

SPECIFICATIONS: Manufacturer: Sheffield (UK) Model: TF1004 Type: CNC Universal Cylindrical Grinder Year of Manufacture: 2000 CNC Control: Fanuc 21i-T with Sheffield conversational grinding software Grinding Capability: External (OD) and Internal (ID) Grinding Mode: Between-centers work with live tailstock center Wheel Dressing: Automatic CNC-controlled dressing cycles using diamond dressing tool Maximum Grinding Wheel Diameter: 24″ (610 mm) Maximum Grinding Wheel Width: 3″ (75 mm) Wheel Mounting: Standard industrial wheel arbor with large cylindrical grinder spindle/flange configuration Grinding Wheel Spindle Speed: 1,800–3,000 RPM range (depending on wheel size and application) Headstock: Swivel-type with variable spindle speed Wheelhead: Swivel-type for OD and ID operations Table Traverse: Hydraulic with fine-feed control Infeed: Precision cross-slide with micrometer dial Coolant System: Flood coolant system, compatible with standard water-soluble grinding coolants Tailstock: Live center, configured for between-centers grinding

CONTROL AND AUTOMATION: The machine is fitted with a Fanuc 21i-T CNC control paired with Sheffield’s conversational grinding software. This combination provides automated grinding cycles and CNC-controlled wheel dressing, reducing operator intervention and ensuring repeatable accuracy across production runs. Dressing is performed through the CNC control using a diamond dressing tool, standard for machines of this class.

FEATURES: The machine supports both live-spindle and dead-center grinding. The universal swivel wheelhead allows angular positioning for external surfaces, with a dedicated internal grinding spindle for bore work. Hydraulic table traverse delivers smooth, consistent longitudinal feed with adjustable dwell at table reversals. The precision cross-feed provides controlled material removal for fine finishes and close tolerances. A rigid cast-iron base ensures vibration dampening and long-term thermal stability.

APPLICATIONS: Aerospace, automotive, bearing, defense, medical device, mold and die, and general precision manufacturing. Ideal for grinding shafts, pins, bushings, bearing races, rollers, valve components, hydraulic spools, spindles, and similar round or tapered workpieces requiring surface finishes in the micro-inch range.
