Eurotech Ultima B620

Single-turret turn/mill center with Y-axis and sub-spindle

Built to order. Ask for lead time.

Overview

Bar parts machined complete in one setup, with a live turret, Y-axis and a sub-spindle

The Ultima B620 is Eurotech's single-turret turn/mill center for bar work, built to finish parts from both sides in one operation. It comes in three spindle sizes: the 51-SLY (ASA 5 in, 2.00 in bar, 5,000 rpm, 34 HP), the 70-SLY (ASA 6 in, 2.76 in bar, 4,500 rpm, 40 to 53.6 HP) and the 80-SLY (ASA 8 in, 3.15 in bar, 3,200 rpm, 33 HP). All three share a 15-station servo turret with live tooling on every station, a 3.54 in Y-axis stroke, a 5,000 rpm ASA 5 in sub-spindle with C-axis and 24.4 in of machining length. The control is FANUC with the i-HMI 15 in touch screen, running Eurotech's own software.

Features

0115-station live servo turretEurotech's servo turret has 15 stations with live tooling on every one, and up to 30 tools can be used together. The rotary tools are driven directly by a liquid-cooled built-in motor rated 18 to 20 HP and up to 6,000 rpm, with the drive lubricated and cooled by oil mist. Indexing takes 0.15 sec per position.
02Y-axis and C-axis on both spindlesThe SLY configuration pairs a 3.54 in Y-axis stroke with C-axis on the main spindle and on the synchronized sub-spindle, so flat and slot milling, keyways, thread milling and grid-hole drilling are done in the same setup. Z runs on roller guideways and X and Y on box ways, on a cast-iron bed Eurotech reinforced by 20% over the previous design.
03Tool setter and tool monitoringThe tool tip touches the probe and the offset is written to the CNC tool table automatically. Eurotech also lists SBS tool monitoring with tool life and wear management, and a tool probe for in-process checks and offset updates.

04Synchronized sub-spindle with parts ejectorThe ASA 5 in sub-spindle runs to 5,000 rpm at 23 to 33.5 HP and has B-axis load detection. Its parts ejector cleans the collet and uses a sensor to confirm the finished part has been ejected.
05Bar feeder interface and part unloadingA bar feeder interface and parts catcher are standard. Eurotech's programmable gantry takes the finished part from the sub-spindle and sets it on a parts conveyor that passes it to a secondary conveyor, to keep parts from being damaged or jammed.
06FANUC i-HMI with Eurotech softwareFANUC i-HMI on a 15 in color touch screen, with Eurotech's custom pages and macros. Eurotech's Gap Elimination Logic removes forced dwells between turning, C-axis and Y-axis moves.
