How much does the Danobat Mikroturn 100 XLD cost?
Price estimate
We do not have a price for the Danobat Mikroturn 100 XLD 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 Danobat Mikroturn 100 XLD is the large-diameter version of the hydrostatic Mikroturn hard turning lathe. It swings parts up to 610 mm (24 in) without a tailstock, the biggest turning diameter in the horizontal range, and its spindle runs to 2,000 rpm, half the speed of the standard machine.
The lower speed follows from the diameter. Surface speed at the rim of a 610 mm (24 in) ring is reached at far fewer revolutions than on a small bush, and a chuck and part of that size carry more inertia. Danobat's series text speaks of a Mikroturn for heavy and large parts up to 610 mm in diameter, and this is that machine.
One row is absent. For turning between centers the table shows no capacity (the cell is marked not applicable), where the Mikroturn 100 lists Ø200 x 350 mm (Ø7.8 x 13.7 in). The XLD should therefore be planned as a chucking machine for rings, discs and housings. Shaft work belongs on another model.
Precision hardware is the range standard: a hydrostatic main spindle with a guaranteed runout error of ≤ 0.1 µm, hydrostatic guideways with 1 µm positioning and 0.2 µm repeatability, and a natural granite base and spindle housing. The control is Siemens Sinumerik One at 0.01 µm resolution. Floor space is 8.6 m² (93 sqft). On a ring this large, air or magnetic chucking and a part probe, all listed options, are the usual means of holding and locating a thin-walled part without distorting it.

Strengths & Limitations
Strengths
- 610 mm (24 in) turning diameter, the largest of the horizontal Mikroturn models
- Guaranteed spindle runout error of ≤ 0.1 µm carried up to large-ring sizes
- 1 µm positioning and 0.2 µm repeatability on hydrostatic guideways with linear scales
- 8.6 m² (93 sqft) of floor space, well under the 12.5 m² (134.5 sqft) of the Mikroturn 500 XL
- Magnetic and air chucks are listed for holding rings
Limitations
- No between-centers capacity: the table marks that row not applicable
- Spindle speed is 2,000 rpm, against 4,000 rpm on the Mikroturn 100
- Small bores on large parts will run below ideal surface speed at 2,000 rpm
- Maximum workpiece weight for this model is not stated on the page

Frequently Asked Questions
01
Danobat does not spell out the letters, but the table shows what changes: the maximum turning diameter without tailstock is 610 mm (24 in), against 380 mm (15 in) on the Mikroturn 100. Spindle speed drops to 2,000 rpm and the floor space rises to 8.6 m² (93 sqft).
02
The row for maximum turning diameter between centers is marked not applicable for this model. A tailstock and steady rest appear in the option list for the range as a whole. If shaft work matters, the Mikroturn 100 XLS is the model with a between-centers rating: Ø240 x 1,000 mm (Ø9.4 x 39.3 in).
03
Both run at 2,000 rpm and both are marked not applicable between centers. The Mikroturn 100 XLD has the larger turning diameter, 610 mm (24 in), in 8.6 m² (93 sqft). The Mikroturn 500 XL turns 500 mm (19.7 in) and occupies 12.5 m² (134.5 sqft). The table does not say what the larger machine offers in return, so ask Danobat about travels and part weight.
04
Siemens Sinumerik One is listed for this model. The series description gives the control resolution as 0.01 µm and names a Fanuc alternative, though the specification table shows Fanuc only in the Baseline column.
