TG-12×4 Thrufeed Microsize
The TG-12×4 Microsize is ideal for projects requiring higher accuracy than standard sizing dials but not as precise as the Hi-Accuracy models. Operators can make size adjustments easily using a pulse generator pendant with increments as fine as .00004” (1 micron). This machine also caters to customers who prefer the convenience of glass scales with digital readouts, making operation more user-friendly.
- Standard capability of grinding to under .00004” ( 1 micron ) - Straight and Round
- Size increments in under .00004” (1 micron)
- Servo Driven Regulating Wheel and Dressers are standard equipment
- Available on Starrett Granite machine bed
Thrufeed grinding a variety of parts is simplified with the Royal Master Thrufeed Microsize system. The addition of a stepping motor on the ram and a hand-held pulse generator gives the operator precise control over the regulating wheel's positioning for accurate sizing.
Many customers using the Microsize grind carbide or ceramic materials with diamond wheels. They find size compensation simple and effective, allowing the use of fine grit diamond wheels without issues. Sizing the regulating wheel in 1-micron increments gives the operator precise control over the part’s diameter. The Microsize also simplifies set-ups with a mode that lets operators run the machine safely with the wheels off, allowing the regulating wheel to retract up to 2 inches for easy grinding wheel changes.
The TG-12×4 has been in production for over 70 years, constantly evolving. New automation types have been added to increase productivity, including step, bowl, and magazine feeding systems for thrufeed grinding. Post-grinding gauging with feedback and a comprehensive suite of data analytics are also available.
The Thrufeed Microsize system includes:
12” Diameter Grinding Wheel, 6” Diameter Regulating wheel
Optional Variable Frequency Drive on grinding wheel spindle for super abrasives or maintaining constant surface footage when grinding
Thrufeed Grind capability
Thrufeed Grind with fine resolution positioning to 0.000,010” of an inch or 1/4 micron increments
2” of Ram Bed travel allowing for removal of Grinding Wheel
Available SBS Wheel balancing and acoustic emissions
