How much does the Ecoca MT-520 cost?
Price estimate
We do not have a price for the Ecoca MT-520 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 Ecoca MT-520 is the largest lathe in Ecoca's catalogue: a 20 in (508 mm) chuck, a swing over the bed of 1,000 mm (39.4 in) and turning lengths of 3,100 / 4,100 / 5,100 mm (122.0 / 161.4 / 200.8 in). Ecoca's own line for it is a 1 meter swing with 5 meter cutting length. Maximum turning diameter is 780 mm (30.7 in).
This is the only model in the range whose spindle speed is printed as two ranges. The low range, marked L, covers 124~496 rpm, and the high range, marked H, reaches 1,800 rpm. A geared low range is what a machine of this size needs, since a large-diameter cut in steel runs at a few hundred rpm and demands torque there, not power at the top end. The motor is listed as 37/45 kW (49.6/60.3 hp). Torque values are not published.
The bed is slanted at 45 degree, and Ecoca ties that to the chip disposal that big turning jobs need. Guideways are box ways, printed in the table as Box way/45. The turret has 12 stations. Ecoca calls the tailstock sturdy and programmable and lists a steady rest as optional; with at least 3,100 mm (122.0 in) between chuck and centre, plan on one.
Installation is a project in itself. Net weight is 18,500 / 20,500 / 22,500 kg (40,785 / 45,194 / 49,603 lb) by bed length, so foundation, cranage and access need to be settled early. The MT-520MC column of the table adds one row, a milling speed of 3,000 rpm, for buyers who want driven tools.

Strengths & Limitations
Strengths
- 20 in (508 mm) chuck with a 1,000 mm (39.4 in) swing over the bed
- Turning lengths of 3,100 / 4,100 / 5,100 mm (122.0 / 161.4 / 200.8 in)
- Two spindle speed ranges: 124~496 rpm (L) and 1,800 rpm (H)
- 37/45 kW (49.6/60.3 hp) spindle motor, the largest in the MT tables
- 45 degree slant bed with box ways and a programmable tailstock
Limitations
- Weighs between 18,500 kg (40,785 lb) and 22,500 kg (49,603 lb), which calls for a prepared foundation
- Top speed of 1,800 rpm rules out efficient small-diameter work
- The steady rest is an option, not standard equipment
- The shortest bed is 3,100 mm (122.0 in); there is no compact version

Frequently Asked Questions
01
Swing over the bed is 1,000 mm (39.4 in), swing over the cross slide 700 mm (27.6 in) and maximum turning diameter 780 mm (30.7 in). The three beds give turning lengths of 3,100, 4,100 and 5,100 mm (122.0, 161.4 and 200.8 in). The chuck is 20 in (508 mm).
02
Ecoca lists two ranges: 124~496 rpm marked L and 1,800 rpm marked H. The spindle drive motor is 37/45 kW (49.6/60.3 hp). The low range is the one used for large-diameter roughing; the table does not state the torque available in either range.
03
Yes, as the MT-520MC. That column of the table is the same as the MT-520 apart from a milling speed of 3,000 rpm. Tool holders and sleeves for living tool are optional, and no milling power or Y axis is listed.
04
Net weight is 18,500, 20,500 or 22,500 kg (40,785, 45,194 or 49,603 lb), rising with the three bed lengths. Ecoca publishes no footprint on the page, so request the foundation drawing together with the quotation.
