Bisite 5th 5-Axis Line Goes Live — Makino Machining Center First Batch Delivered

Makino 5-Axis Installed — First Article Precision Validation Passed on First Try

In February this year, the newly procured Makino D500 5-axis vertical machining center completed installation at Bisite. This is not our first 5-axis — but the selection process took six months, because "functional" and "truly capable" are two very different things in 5-axis.

After 3 months of commissioning, thermal run-in, and process validation, the first customer parts were delivered in late April. CMM full-dimension inspection reports show key feature dimensional deviation stable within ±3μm, with roundness and cylindricity all passing.

Why Makino

To be honest, the 5-axis market is highly competitive — we evaluated DMG MORI, Mazak, and Makino. We chose Makino for two core reasons:

• Thermal displacement compensation: Makino GI control system compensates spindle thermal deformation in real-time, delivering noticeably better long-run precision consistency
• Rigidity: The D500 bed uses a one-piece cast iron structure — chatter control during interrupted cuts is significantly better than our previous equipment

What This Means for Customers

With this additional 5-axis, Bisite machining capability for complex curved parts (impellers, housings, multi-face structural parts) has qualitatively improved. Parts that previously required 3 clampings now complete in a single setup — fewer clampings means better precision assurance.

Our current 5-axis capability covers:

• Max workpiece size: Ø700 x 500mm
• Positioning accuracy: ±3μm
• Repeatability: ±2μm
• Tool capacity: 60 tools

Customers with complex part requirements are welcome to bring drawings for discussion. What we can do, you can see on the shop floor.
