How much does the Supertec TPL-2448CNC cost?
Price estimate
We do not have a price for the Supertec TPL-2448CNC 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 TPL-2448CNC is a CNC grinder built for one product: gear racks. Supertec sells it in the STMantα series as a gear rack specialized grinder, the shortest of three, with a 600 × 1,200 mm (24 × 48 in) table. The frame is that of a column-type surface grinder. What changes is how the axes are used, since a rack tooth is formed by stepping a profiled wheel along the blank one pitch at a time.
That explains the feed figures. The table's maximum feeding speed is 8 m/min, a fraction of what a reciprocating surface grinder runs, because here the table indexes and holds position. Its X servo motor is 2.2 kW (3.0 hp). The Y axis rapids at 25 m/min and the cross axis (Z) at 1~15 m/min over 625 mm (25 in) of travel, each with a 1.8 kW servo motor and handwheel steps down to 0.001 mm.
Rack blanks are held magnetically. The electromagnet alone weighs 385 kg, and the table is rated for 1,700 kg (3,748 lb) in total. The wheel is Ø405 × 50 × Ø127 mm (Ø16 × 2 × Ø5 in) at 1,800 rpm on a 7.5 HP (5.6 kW) spindle, with 700 mm (28 in) from spindle center to the working table.
At 7,280 kg (16,050 lb) net and 3,020 × 2,280 × 2,450 mm (119 × 90 × 96 in) overall, it is the compact way into rack grinding. Supertec's table does not state module range or pitch accuracy, so those need to come from the quotation.

Strengths & Limitations
Strengths
- Purpose-built for gear rack grinding, with servo motors on all three axes
- Table load of 1,700 kg (3,748 lb) on a 600 × 1,200 mm (24 × 48 in) table
- Y axis rapid of 25 m/min shortens wheel retract and dress moves
- Smallest footprint of the TPL machines at 3,020 × 2,280 × 2,450 mm (119 × 90 × 96 in)
- Electronic handwheel steps of 0.1 / 0.01 / 0.001 mm on Y and Z
Limitations
- No module, pitch or rack accuracy figures are published in the table
- Rack length is bounded by the 1,200 mm table; the TPL-2480CNC takes 2,000 mm
- Spindle is 7.5 HP (5.6 kW), modest for wide form wheels
- Table feed is limited to 8 m/min, so the machine is a poor substitute for a general surface grinder

Frequently Asked Questions
01
Grinding the tooth profile of gear racks. Supertec lists the TPL-2448CNC, TPL-2460CNC and TPL-2480CNC together as gear rack specialized grinders in its STMantα series. This is the shortest of them, with a 600 × 1,200 mm (24 × 48 in) table.
02
The table is 600 × 1,200 mm (24 × 48 in). Supertec does not publish a maximum rack length or module for the machine, so the usable tooth length for a given rack should be confirmed with the maker. The cross (Z) travel is 625 mm (25 in).
03
A 7.5 HP (5.6 kW) spindle motor with a wheel spindle speed of 1,800 rpm and a wheel linear velocity of 2,000 m/min. The grinding wheel is Ø405 × 50 × Ø127 mm (Ø16 × 2 × Ø5 in), and the spindle center sits up to 700 mm (28 in) above the working table.
04
Net weight is 7,280 kg (16,050 lb) and gross weight 8,080 kg (17,813 lb). Overall size is 3,020 × 2,280 × 2,450 mm (119 × 90 × 96 in). The next size up, the TPL-2460CNC, weighs 8,000 kg (17,637 lb).
