1.Description
The Okuma BL-D75A(M Axis)paired with the Motor BL-H201E-30(62.5 Ein)forms a specialized drive system designed for M-axis applications in industrial machinery.Manufactured by Okuma,this combination integrates robust motor performance with precise axis control,delivering reliable power and accurate motion control for medium to heavy-duty industrial processes.
The Okuma BL-D75A serves as the core driver for the M axis,while the BL-H201E-30 motor,with its 62.5 Ein parameter,ensures consistent torque and speed output.Together,they are ideal for applications such as CNC lathe tool turrets,milling machine auxiliary axes,and automated feeding mechanisms,where M-axis precision is critical.
2.Application Scenarios
A precision parts factory was facing issues with their CNC lathe’s M-axis tool turret,which often had positioning errors during tool changes,leading to machining inaccuracies and 12%of defective parts.After upgrading to the Okuma BL-D75A(M Axis)with Motor BL-H201E-30(62.5 Ein),the situation improved significantly.The BL-D75A’s precise axis control,combined with the BL-H201E-30’s stable 62.5 Ein performance,reduced tool change positioning errors by 80%.Defective parts dropped to 2%,and production efficiency increased by 18%due to faster,more accurate tool changes.
In a gear manufacturing plant,the M-axis of their hobbing machine struggled with inconsistent feed rates,affecting gear tooth precision.Installing the BL-D75A and BL-H201E-30 resolved this,as the motor’s 62.5 Ein parameter ensured steady feed,improving gear tooth accuracy by 0.01mm and reducing rework by 25%.

4.Technical Principles and Innovative Values
Innovation Point 1:The Okuma BL-D75A(M Axis)features M-axis dedicated control algorithms,optimizing tool change and auxiliary motion sequences.Compared to general-purpose drivers,it reduces M-axis response time by 40%,ensuring rapid,precise tool changes in CNC lathes—critical for high-volume production.
Innovation Point 2:The BL-H201E-30 motor’s 62.5 Ein parameter enables fine-tuned motion calibration,minimizing cumulative positioning errors in M-axis operations.This reduces axis backlash by 30%compared to motors without such calibration,enhancing tool turret and auxiliary axis precision.
Innovation Point 3:The integrated system of BL-D75A and BL-H201E-30 supports real-time M-axis load monitoring.It adjusts torque output dynamically during sudden load changes(e.g.,tool engagement),preventing stalls and reducing mechanical wear by 20%in long-term use.
5.Application Cases and Industry Value
Case 1:An automotive parts manufacturer integrated the Okuma BL-D75A(M Axis)with BL-H201E-30(62.5 Ein)in their CNC mill’s rotary table M-axis.The system’s precise positioning ensured the table rotated to exact angles for multi-face machining,improving part dimensional accuracy by 0.02mm.This reduced assembly fitting issues by 30%and increased production throughput by 22%.
Case 2:In a medical device assembly line,the M-axis of their automated screwdriving machine used the BL-D75A and BL-H201E-30.The motor’s 62.5 Ein parameter ensured consistent screw tightening torque,reducing under/over-tightening by 90%.This met strict medical device standards and increased assembly line uptime by 15%.
