5BC-838

Overview

Model 5BC-838 is a 5-axis double column machining center with linear guideways and a Taiwan-made 5 axis head featuring a high-rigidity FORK structure; the machine head section size is 540 x 521 mm and the spindle is specified as 15,000 rpm built-in 88.3 Nm. Maximum torque output for B axis/C axis is 1,000/1,000 NM and the controller is HEIDENHAIN TNC640 with a Hartford-base self-display designed for Heidenhain TNC 640. The machine uses oil-air lubrication for the spindle and includes a 2-Year Warranty Without Operation Hours Limit per Spindle with Oil-Air Lubrication. Structural features include a one-piece column with extended span 25% wider and width 15% rigidity increase, Z-axis four-line guideways providing a 30% increase in load capacity versus two-line rails, and a slant beam crossbeam with 45° force flow design; patents cited are M437316 and M435318. Worktable size is 8000 x 2500 mm with Max. load (Average) 27000 kg, travels are X axis travel 8000 mm, Y axis travel 3800 mm, and Z axis travel 1000 / opt.1200 mm; spindle nose taper options are HSK-A63 / HSK-A100 and spindle speed (Built-in) is 15000/24000 (HSK-A63);12000 (HSK-A100) rpm. ATC Capacity is listed as 32 /40 60 (A-Type) pcs with Max. tool loading 7 ( HSK-A63) ;20 ( HSK-A100) kg, and spindle drive motor (Cont. / 30 min) values are 29.5 / 37 opt. 30 / 37 (HSK-A63);34 /43 (HSK-A100) Kw. Inspection and accuracy features include OMV (On Machine Verification) 3D Inspection and a reported result of 114 spots test approved within tolerance (± 0.02mm). The 5BC-838 is presented as a solution for aerospace components and is described as a high-efficiency, high-speed 5-axis machining center for aerospace components. On-machine 3D inspection (OMV) is employed to ensure each workpiece is qualified, with reported 3D contouring accuracy results (114 spots test within ± 0.02mm).
