Price estimate
We do not have a price for the Nidec Machine Tool ZFA260 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 Nidec Machine Tool ZFA260 is a gear grinding machine for workpieces up to 260 mm (10.2 in) in diameter. As standard it grinds module 1 - 6 gears. Module 0.5 - 1.0 is available as an option, so a shop that grinds fine-pitch gears should specify that range when ordering.
The grinding wheel is listed with an outside diameter of 208 - 275 mm (8.2 - 10.8 in). That is a span of wheel sizes, which means surface speed at a given spindle speed depends on which end of the span the wheel is at. The grinding spindle reaches 8,000 min-1 and the table 2,000 min-1.
The base is epoxy granite, a material used for its vibration damping, which shows up directly in the surface a finishing process leaves on the tooth flank. Installation needs attention on two counts: the machine weighs 15,000 kg (33,069 lb) and the power requirement is 110 kVA. It is still lighter than the MSS300 from the same maker, which is listed at 18,000 kg (39,683 lb). Nidec Machine Tool's table gives no grinding spindle power, axis travels or control.

Strengths & Limitations
Strengths
- Standard module range of 1 - 6 on workpieces up to 260 mm (10.2 in) in diameter
- Epoxy granite machine base, which damps vibration during finish grinding
- Grinding spindle speed up to 8,000 min-1 with table speed up to 2,000 min-1
- Fine-pitch range of module 0.5 - 1.0 can be added as an option
Limitations
- Module 0.5 - 1.0 is an option, not part of the standard machine
- A power requirement of 110 kVA and a weight of 15,000 kg (33,069 lb) both call for site preparation
- The published table lists no grinding spindle power, axis travels or control

Frequently Asked Questions
01
Module 1 - 6 is the standard range. Nidec Machine Tool lists module 0.5 - 1.0 separately as an optional range, so gears finer than module 1 need that option. Maximum workpiece diameter is 260 mm (10.2 in) in either case.
02
The wheel row gives a grinding wheel outside diameter of 208 - 275 mm (8.2 - 10.8 in). The grinding spindle runs at up to 8,000 min-1, and the wheel's surface speed at any spindle speed depends on where in that diameter span the wheel is.
03
A supply sized for the listed power requirement of 110 kVA and a floor that carries the machine weight of 15,000 kg (33,069 lb). The machine base is epoxy granite. Axis travels and overall dimensions are not in the published table, so ask for a layout drawing.
