Price estimate
We do not have a price for the Supertec PL-2550CNC 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 Supertec PL-2550CNC is a saddle-type CNC surface grinder with a 250 × 500 mm (9.8 × 19.7 in) table, the smaller of two models in the maker's high-precision saddle range. Vertical and cross axes run on linear guide ways with ball screws, each driven by an 800W AC servo motor, and the control is a SIEMENS 828D or FANUC Series 0i-MF.
Supertec offers the longitudinal axis in two builds, which the table marks H and B. H is the traditional arrangement, a box way table moved by a hydraulic cylinder, with table speed of 3~25 m/min. B replaces the hydraulics with a linear guide way, ball screw and 1KW AC servo motor, for 1~15 m/min. The B build gives the control a positioned X axis; the H build gives the faster reciprocation that plain surface grinding likes.
This is a small-wheel machine. The wheel measures 180 × 13 × 31.75 mm and turns at 3,500 rpm on 60 Hz supply, with a 3 HP (2.2 kW) spindle motor. That suits toolroom work, punches, inserts and small die components, and it rules out heavy stock removal across the full table.
Four grinding modes are programmed: surface, criss-cross, plunge and pitch, the last for slots at different pitch and the same depth. The minimum feed setting is 0.001 mm. The machine occupies 2,800 × 2,500 × 2,300 mm (110.2 × 98.4 × 90.6 in) and weighs 2,500 kg (5,511 lb).

Strengths & Limitations
Strengths
- Full CNC from SIEMENS 828D or FANUC Series 0i-MF on a compact 250 × 500 mm table
- Vertical and cross axes on linear guide ways with ball screws and 800W AC servo motors
- Longitudinal axis available as hydraulic (H) or ball screw with servo (B)
- Programmed surface, criss-cross, plunge and pitch grinding modes
- Minimum feed setting of 0.001 mm
Limitations
- Spindle motor is 3 HP (2.2 kW), well below the 7.5 HP (5.6 kW) of the PL-3060CNC
- The 13 mm wide wheel covers little width per pass
- The B build limits table speed to 1~15 m/min
- Supertec's table states no maximum table load for this model

Frequently Asked Questions
01
The table lists SIEMENS 828D or FANUC Series 0i-MF. Grinding modes are surface, criss-cross, plunge and pitch, the pitch mode being described as different pitch and same depth. The minimum feeding setting is 0.001 mm.
02
They are two versions of the longitudinal (X) axis. H uses a box way with a hydraulic cylinder and a 1HP motor, for a table speed of 3~25 m/min. B uses a linear guide way with ball screw and a 1KW AC servo motor, for 1~15 m/min. Vertical and cross axes are the same on both.
03
The grinding surface of the table and the maximum grinding surface are both 250 × 500 mm (9.8 × 19.7 in). The maximum distance from spindle center to table is 550 mm (21.7 in), and the rapid power cross feed is 1,100 mm/min.
04
The PL-3060CNC is the larger sibling, with a 300 × 600 mm (11.8 × 23.6 in) table, a 7.5 HP (5.6 kW) spindle and a 355 × 50 × 127 mm wheel, at 3,000 kg (6,614 lb). The PL-2550CNC has a 3 HP (2.2 kW) spindle and a 180 × 13 × 31.75 mm wheel and weighs 2,500 kg (5,511 lb). Controls and grinding modes are shared.
