How much does the Supertec PMG-60 / 100 CNC cost?
Price estimate
We do not have a price for the Supertec PMG-60 / 100 CNC 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
A universal grinder earns its place when one part needs outside diameters, a taper, a shoulder and a bore ground without being re-chucked, and the Supertec PMG-60 / 100 CNC is built for that. Its wheel head sits on an automatic B-axis and, in the maker's words, carries 2 OD wheels and 1 ID wheel. The CNC indexes the head to bring each wheel to the work.
Two lengths are listed. The PMG-60 CNC has 600 mm (24 in) between centers and a maximum grinding length of 500 mm (20 in); the PMG-100 CNC has 1,000 mm (40 in) and 800 mm (32 in). Swing over the table is Ø360 mm (14 in) on both, and the load between centers is 150 kg (330 lb).
Each length comes as an (A) or a (B) machine, and the difference is the internal spindle. Type A uses a grease spindle of 8,000/15,000/20,000/30,000 rpm with a 1.5 kW motor. Type B has a high frequency built-in spindle rated 40,000 rpm and 6 kW, and its workhead motor doubles from 1.5 kW (2.0 hp) to 3 kW (4.0 hp). Small, deep bores are the reason to pay attention to this choice: the ID shaft diameter range is Ø7~Ø25 mm (Ø0.27~Ø1 in).
The left-hand OD wheel is Ø405 × 50 × Ø127 mm (Ø16 × 2 × Ø5 in), and the OD spindle runs at 1,575 / 1,795 rpm depending on mains frequency. X infeed travel is 275 mm (10.8 in), which leaves room for the swinging head to clear the work. The table names the controller only as 0i-TF.

Strengths & Limitations
Strengths
- Automatic B-axis wheel head with 2 OD wheels and 1 ID wheel, so external, taper, shoulder and internal grinding are done in a single setup
- Choice of ID spindle: grease type at 8,000/15,000/20,000/30,000 rpm (A) or high frequency built-in at 40,000 rpm (B)
- 275 mm (10.8 in) of X infeed travel with a Ø0.001 mm (Ø0.0001 in) minimum increment
- The B-axis can be fitted with a Heidenhain or Fagor encoder, according to Supertec's description
- Coolant is routed through the whole machine by a nozzle system to carry heat and grinding chips away
Limitations
- Maximum grinding length is 500 mm (20 in) or 800 mm (32 in), shorter than the 600 mm (24 in) or 1,000 mm (40 in) between centers
- The base wheel spindle motor is 3.75 kW; the 5 kW motor is an option
- Table swivel is 5° on the PMG-60 CNC and 3° on the PMG-100 CNC
- ID tooling is limited to shaft diameters of Ø7~Ø25 mm (Ø0.27~Ø1 in)
