BVM Series

The DN Solutions (formerly Doosan Machine Tools) BVM Series is the latest premium class Vertical Machining Center that is built to deliver high speed and high precision machining in a rigid and compact bridge frame structure. The BVM features a 15,000 rpm spindle, ball nut cooling, spindle thermal displacement control with multiple sensors, and optimized axes drive acceleration and deceleration.

BVM 5700

DN Solutions BVM 5700 Bridge-Type Vertical Machining Center

The DN Solutions BVM 5700 is a 3-axis vertical machining center built on a double-column bridge frame, designed for shops that need high-speed cutting and high precision from the same machine. It pairs a built-in 15,000 RPM spindle rated at 18.5/37 kW (24.8/49.6 hp) and 214 Nm with 1,050 x 570 x 460 mm (41.33 x 22.44 x 18.11 in.) of X, Y, and Z travel, a 1,300 x 570 mm table rated for 1,000 kg, and a 40-tool double-arm ATC with a 1.3-second tool-to-tool change. Ball nut cooling on all three axes and multi-sensor thermal compensation control heat growth, and rated positioning accuracy is 0.011 mm on X, 0.008 mm on Y, and 0.007 mm on Z (ISO 230-2). Ellison Technologies, the largest DN Solutions distributor in North America, supplies the BVM 5700 as part of its vertical machining centers lineup.

Die and Mold Work in Pre-Hardened Steel

The BVM 5700 is set up for die and mold cutting in pre-hardened steel. Its through-spindle air can blow chips out of deep cavities where coolant isn't wanted, and the Smooth Surface Package in the FANUC 0i-Plus control is aimed at finishing passes. The thermal compensation system reads multiple sensors on the headstock and bed and runs the data through five algorithms to keep Z-axis growth in check over long mold-finishing cycles. Shops that want more speed for small-tool finishing can order the optional 20,000 RPM spindle. Ellison's engineering solutions team can help prove out toolpaths and fixturing for a new mold or die job.

Medical Components and Coolant-Sensitive Parts

Some medical components can't be exposed to coolant during machining. The BVM 5700's through-spindle air, triggered by M-code, pushes air through the tool in place of coolant for those jobs. The same approach works on plastics. Rated repeatability of 0.006 mm on X, 0.005 mm on Y, and 0.004 mm on Z supports the tight tolerances common in medical part work.

Aluminum and Carbon Steel Production Parts

For general production work in aluminum and carbon steel, the built-in spindle delivers 214 Nm of torque at up to 15,000 RPM. Through-spindle coolant reaches about 215 to 225 psi at the tool tip from a 20 bar pump. Rapid traverse runs 42 m/min (1,653 ipm) on X and Y and 36 m/min (1,417 ipm) on Z, and Adaptive Feedrate Control adjusts the feed to spindle load during roughing. Tool Load Monitoring stops the machine on a broken or worn tool before it damages the part.

FAQ Section

What is the DN Solutions BVM 5700 used for?

The BVM 5700 is a 3-axis bridge-type vertical machining center for high-speed, high-precision milling. DN Solutions highlights die and mold cutting in pre-hardened steel, plastics, and medical components that need coolant-free machining. It runs a built-in 15,000 RPM spindle with 1,050 x 570 x 460 mm of travel and a 40-tool ATC.

How does the BVM 5700 compare to the DNM 5700 4th Gen?

Both machines share the same 1,050 mm X and 570 mm Y travel, the same 1,300 x 570 mm table rated for 1,000 kg, and the same 42/42/36 m/min rapid traverse rates. The BVM 5700 uses a double-column bridge frame and a built-in 15,000 RPM spindle rated at 18.5/37 kW and 214 Nm. The DNM 5700 4th Gen uses a box-type column and offers either an 8,000 RPM, 286 Nm high-torque spindle or a 15,000 RPM, 117.8 Nm high-speed spindle. The DNM 5700 has more Z travel (510 mm vs. 460 mm). The BVM 5700 is the heavier machine at 7,500 kg vs. 6,500 kg.

What industries is the BVM 5700 suited for?

The BVM 5700 fits mold and die shops working in pre-hardened steel, medical component manufacturers that need coolant-free machining with through-spindle air, and general production shops cutting aluminum and carbon steel.

What spindle does the BVM 5700 have?

The BVM 5700 has a built-in 15,000 RPM spindle with a CAT 40 Big Plus taper, rated at 18.5/37 kW (24.8/49.6 hp) and 214 Nm (157.9 ft-lbs) at S3 15% duty. An oil chiller circulates refrigerated oil around the spindle, and an air-oil mist system lubricates the bearings. It accelerates from 0 to 15,000 RPM in 1.9 seconds and decelerates in 1.7 seconds. A 20,000 RPM spindle is available as an option.

How accurate is the BVM 5700?

Rated positioning accuracy is 0.011 mm (0.00043 in.) on X, 0.008 mm (0.00031 in.) on Y, and 0.007 mm (0.00027 in.) on Z. Repeatability is 0.006 mm on X, 0.005 mm on Y, and 0.004 mm on Z. DN Solutions measures these to ISO 230-2 and guarantees them only when the machine is installed on a foundation that meets its minimum requirements.
