ESTARTA spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of spindles and motor spindles on ESTARTA grinders, a Basque brand from Elgoibar specializing in centerless grinders and part of the Danobat group.
ESTARTA, a historic Basque machine tool brand
TLDR: Estarta y Ecenarro, founded in Elgoibar (Spanish Basque Country) in 1914, gave rise to the ESTARTA brand of centerless grinders. It now belongs to the Danobat group, within the Mondragón cooperative.
The company was founded in 1914 by José León Ciarán and Eulogio Estarta to build machines for the arms industry, then drilling machines. Teodoro Ecenarro joined them in 1915 and the company took the name Estarta y Ecenarro in 1920. After the Spanish Civil War, it moved into sewing machines (Sigma brand) while developing its machine tool business: eccentric presses, hydraulic copy lathes and grinders. In the 1950s it exported to more than 50 countries and employed 520 people.
The company closed in 1995, but its grinding branch was taken over by the Danobat group. In 2007, Estarta Rectificadora, S. Coop. was set up within Danobat to continue building machines under the ESTARTA brand in Elgoibar. See also our page on Danobat spindles and motor spindles.
Centerless grinders on the used machine market
TLDR: ESTARTA 301, 320, 322, 327 and 327 CNC models are widely found on the used machine market, often in France. Each one has a grinding wheel spindle and a regulating wheel spindle.
On a centerless grinder, the part is held between the grinding wheel, the regulating wheel and a work rest: accuracy therefore depends on the stability of both spindles. An ESTARTA spindle with a worn bearing causes cylindricity errors and chatter marks. Spindle specifications for ESTARTA models are not published in the sources we consulted: power, speeds and bearings are to be confirmed in our quote, from the machine's nameplate.
