Our best estimate for a cnc grinding machine in this class — not a quote from Vollmer. Configuration moves it a long way.

Overview

The Vollmer QXD200 is described in this table as a 5-axis machine (X, Y, Z, A, C) that pairs rotary EDM erosion with a diamond grinding wheel, for tools up to 200 mm (7.9 in) in diameter and 350 mm (13.8 in) long. Vollmer's current lineup does not show this model. The table has not been checked against a maker document, so what follows rests on the listed figures.

Erosion uses a rotating copper or graphite disc. Because a diamond grinding wheel is listed next to it, a tool can be eroded and ground in one clamping instead of being moved between two machines, which removes a re-clamping error from the job. The C axis is listed as ±360° continuous.

Positioning accuracy is given as < 0.002 mm (< 2 µm) and the control as Vollmer VC 756 with VPPS. Machine weight is ~4,500 kg (9,921 lb). There is no row for the erosion generator, spindle power, axis travel or any loader, so a buyer looking at a used QXD200 should get those from the machine's documentation and see both processes run before deciding.

Frequently Asked Questions

01 What size tools does the Vollmer QXD200 take?

The listed maximum is 200 mm (7.9 in) in tool diameter and 350 mm (13.8 in) in tool length, on five axes (X, Y, Z, A, C) with a C axis given as ±360° continuous. Check the figures on the machine, since the table is unconfirmed.

02 Does the QXD200 erode or grind?

Both, according to the listed figures. The erosion method is rotary EDM with a copper/graphite disc, and a diamond grinding wheel is listed as well. That lets a tool be eroded and ground without re-clamping it on a second machine.

03 How heavy is the QXD200 and how accurate is it?

The listed machine weight is ~4,500 kg (9,921 lb) and the listed positioning accuracy is < 0.002 mm (< 2 µm). No connected load, air supply or footprint is given, so plan the installation from the machine's own documents.
