How much does the Star SU TRU TECH T93XM-A cost?
Price estimate
We do not have a price for the Star SU TRU TECH T93XM-A 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 T93XM-A is the autoloading version of Star Cutter's 3-axis centerless profile grinder. It takes parts from 3 mm to 25 mm in diameter, with a maximum grind diameter of 1 in (25 mm) and a maximum grind length of 10 in (254 mm), and feeds them from a 3-pallet system.
The loader is the point of this model. The pallets are modular, and the pallet load area is isolated from the grinding environment, so an operator can reach the pallets while the machine is grinding; robotic lockouts guard that access. Star Cutter states that the system increases lights-out capacity by up to 250% over its previous models.
Underneath is the manual machine of the same series. Travels are 16 in (400 mm), 9 in (225 mm) and 8.6 in (218 mm), the spindle is 3 hp (2.2 kW) at up to 5,000 RPM, and the wheel is up to 8 in (200 mm). The part is held in the PP-8000 or TT-5000 grinding unit, and the stated minimum accuracy and repeatability are ±0.00005 in (0.0013 mm) and ±0.000025 in (0.0006 mm).
The trade against the manual machine is part size. The TRU TECH T93XM grinds up to 3 in (75 mm) in diameter, where this model is listed at 1 in (25 mm). The grind length figure is the longer one here, and Star Cutter notes that still longer lengths are possible with optional staging. Shipping weight is 5,800 lbs (2,631 kg).

Strengths & Limitations
Strengths
- 3-pallet autoloader with modular, high-capacity pallets
- Pallet load area is isolated from the grinding environment, so pallets can be reached during the cycle
- Same PP-8000 or TT-5000 grinding unit and ±0.00005 in (0.0013 mm) minimum accuracy as the manual machine
- Simulation tools for virtual grinding of parts before a blank is cut
Limitations
- Maximum grind diameter is 1 in (25 mm), against 3 in (75 mm) on the TRU TECH T93XM
- Parts under 3 mm in diameter are outside the stated range of the system
- Spindle power is 3 hp (2.2 kW), as on the manual machine: the automation adds running hours, not removal rate

Frequently Asked Questions
01
Automatic loading. The grinder itself is the same 3-axis machine with the same travels, 3 hp (2.2 kW) spindle and grinding unit. The T93XM-A adds a 3-pallet system, automation software and simulation tools, and Star Cutter says it increases lights-out capacity by up to 250% over previous models.
02
Star Cutter states that the system accommodates parts from 3 mm to 25 mm in diameter and up to 250 mm in length. The specification table gives a maximum grind diameter of 1 in (25 mm) and a maximum grind length of 10 in (254 mm), with longer lengths possible with optional staging.
03
Yes. The pallet load area is isolated from the grinding environment, which allows full access during the grinding cycle, and robotic lockouts are there to keep that access safe. The pallets are modular and described as high-capacity; the maker does not publish a part count per pallet.
04
The table lists a minimum accuracy of ±0.00005 in (0.0013 mm) and a minimum repeatability of ±0.000025 in (0.0006 mm), the same figures as the manual machine. The workholding is the patented Precision Grinding Unit, which lets parts be reloaded and reground without introducing shank run-out.
