How much does the Star SU TRU TECH TT1020M cost?
Price estimate
We do not have a price for the Star SU TRU TECH TT1020M that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Star SU TRU TECH TT1020M is a precision OD grinder that works between centers: 10 in (254 mm) of swing over the table, 20 in (508 mm) between centers and a maximum grinding diameter of 9 in (229 mm). Unlike the centerless TRU TECH models it holds the workpiece on centers, so every diameter is ground true to one axis.
Load capacity between centers is 176 lbs (80 kg). The centers are MT3, with MT4 as an option, the quill travels 1 in (25 mm), and the distance from the spindle center to the slide table is 5 in (127 mm). A hydraulic tailstock is on the option list for repeated loading.
Star Cutter programs the machine with its icon-based Conversational Software and states that operators can program shapes and profiles in minutes. Profiles are produced with a standard 1A1 wheel, and the listed operations are profile grinding and plunge grinding. Training and maintenance modules are built in.
The standard machine has a semi-enclosed splash guard and in that form weighs 6,840 lbs (3,104 kg) net and 8,380 lbs (3,802 kg) gross. Telescoping safety splash doors are an option. So are an ID spindle attachment, probing for length and part orientation, an oil chiller with 5 µm filtration, several diamond and rotary dressing systems and SBS wheel balancing. The maker's table gives no wheel size, spindle power or accuracy figure for this model.
