Our best estimate for a horizontal machining centers (hmc) in this class — not a quote from Okuma. Configuration moves it a long way.

Overview

The Okuma MA-600HII is listed as a No. 50 taper horizontal machining center with a 630 x 630 mm (24.8 x 24.8 in) pallet, a maximum work weight of 1,200 kg (2,640 lb) and 60 m/min (2,362 ipm) rapids. The control is the OSP-P300MA; the table notes that the MA-600HIII carries the OSP-P500.

For heavy cutting the listed figures are spindle torque of 606 Nm (447 ft-lb) on a No. 50 (CAT 50 / BT 50) taper, with a tool change of 2.8 sec tool-to-tool. Y travel is 900 mm (35.4 in) and the maximum workpiece height is 1,200 mm (47.2 in), so the top of a full-height part sits above the reach of the spindle and tall work has to be planned around the travel, not the height limit. The table indexes in 0.001° increments.

Accuracy is listed as ±0.004 mm (±0.00016 in) positioning and ±0.002 mm (±0.00008 in) repeatability. Machine weight is given as 53,900 lb, which is the number to take to the rigger and to the floor-loading check.

Several other listed figures do not agree with each other: X and Z travel, top spindle speed, spindle power, magazine capacity and maximum workpiece diameter each appear with more than one value. Take those from the machine's own specification sheet and nameplate before quoting work on an MA-600HII.

For reference, the MA-600HIII is listed with a 630 × 630 mm (24.80 × 24.80 in) pallet, travels of 1,050 mm (41.3 in) in X, 900 mm (35.4 in) in Y and 1,000 mm (39.4 in) in Z, a 30/22 kW (40/30 hp) spindle and 60 m/min (2,362 ipm) rapids.

Strengths & Limitations

Strengths

Spindle torque listed at 606 Nm (447 ft-lb) on a No. 50 (CAT 50 / BT 50) taper
60 m/min (2,362 ipm) rapid traverse, the same rate listed for the MA-600HIII
Listed positioning accuracy of ±0.004 mm (±0.00016 in) and repeatability of ±0.002 mm (±0.00008 in)
Maximum work weight of 1,200 kg (2,640 lb) on a 630 x 630 mm (24.8 x 24.8 in) pallet
Tool change listed at 2.8 sec tool-to-tool

Limitations

The listed figures for X and Z travel, spindle speed, spindle power and magazine capacity conflict, so each must be confirmed from the machine's own documentation
Workpiece height of 1,200 mm (47.2 in) exceeds the 900 mm (35.4 in) of Y travel
Listed machine weight is 53,900 lb, which calls for a floor-loading and rigging check before installation

Best For

Heavy milling and boring with No. 50 tooling and 606 Nm (447 ft-lb) of spindle torque Castings and weldments up to 1,200 kg (2,640 lb) Prismatic parts on a 630 x 630 mm (24.8 x 24.8 in) pallet Multi-face work indexed in 0.001° increments

Frequently Asked Questions

01 How much weight can the Okuma MA-600HII pallet carry?

The listed maximum work weight is 1,200 kg (2,640 lb) on a 630 x 630 mm (24.8 x 24.8 in) pallet. The listed maximum workpiece height is 1,200 mm (47.2 in). The listed figures for workpiece diameter do not agree, so confirm the swing from the machine's own documentation.

02 What spindle does the MA-600HII have?

The listed spindle is a No. 50 (CAT 50 / BT 50) taper with 606 Nm (447 ft-lb) of torque. The listed figures for top speed and motor power do not agree with each other, so take those from the specification sheet or nameplate of the machine in question.

03 How accurate is the MA-600HII?

The listed positioning accuracy is ±0.004 mm (±0.00016 in) and the listed repeatability is ±0.002 mm (±0.00008 in). The table indexes in 0.001° increments. On a machine that has been in service, ask for a recent calibration or ballbar report as well.

04 What is the difference between the MA-600HII and the MA-600HIII?

The table lists the OSP-P300MA control for the MA-600HII and notes the OSP-P500 on the MA-600HIII. The MA-600HIII is listed with a 630 × 630 mm (24.80 × 24.80 in) pallet, 1,050 mm (41.3 in) of X travel, 900 mm (35.4 in) of Y, 1,000 mm (39.4 in) of Z and 60 m/min (2,362 ipm) rapids.
