Drilling & Milling Machine for High-Precision Gear Housing Bores

Gearbox performance is highly sensitive to the coaxial relationship between bearing seats. The Drilling & Milling Machine uses a rigid spindle housing and low runout bearing structure to maintain absolute coaxiality during multi-bore drilling cycles. Any deviation in bore alignment directly increases bearing heat and transmission noise, which this machine effectively prevents. 

Drilling & Milling Machine Multi-Bore Pattern Synchronization

Gear housings require precise positional symmetry across multiple functional holes such as bearing seats, oil passages, and fastener interfaces. The Drilling & Milling Machine utilizes synchronized axis interpolation with micro-step resolution to eliminate pattern distortion and pitch errors in multi-hole machining.

Drilling & Milling Machine Sealing Surface Milling for Oil Retention

After drilling, sealing surfaces must be milled to ensure oil-tight contact. The Drilling & Milling Machine maintains constant cutting force during face milling to achieve uniform surface roughness, preventing micro-leakage in gearbox assembly zones.

Drilling & Milling Machine Vibration Control for Cast Iron Gear Housings

Cast iron gear housings generate intermittent cutting resistance due to graphite distribution. The vibration damping structure of the Drilling & Milling Machine stabilizes the cutting process, producing consistent bore roundness and preventing micro-cracks on functional surfaces.

Drilling & Milling Machine Production Stability in Gearbox Manufacturing

Integrating drilling and milling into a single setup eliminates cumulative reference shifts, ensuring every functional surface maintains a fixed geometric relationship throughout the machining cycle.

People Also Ask – FAQ

What causes bearing bore ovality during gearbox machining?
Ovality is primarily caused by spindle vibration, thermal distortion, and unstable feed force under heavy cutting load.

How does bore misalignment affect gearbox service life?
Misalignment causes uneven bearing load, accelerates fatigue failure, and increases operating temperature.

Is re-clamping allowed for high-precision gear housing machining?
Re-clamping significantly increases geometric deviation and should be avoided for precision transmission components.
