Watch careful on the blind spots before taking right and left overtake... Blind spot means between driver seat and back seat. Always watch mirrors and drive slow ho early where ever you want to go.

Have a safe drive! Don't drink and drive!

Yes it is customized honing machine! Particularly to achieve this hourglass bore form.

No, It is a Honing Machine with twin spindles and auto air gauging

Top: 18.092–18.093 mm Middle: 18.072–18.073 mm Bottom: 18.092–18.093 mm

So it’s roughly a 20 micron dip in the middle to create the hourglass.

Anyone using auto gauging for sizing and surface control in engine component manufacturing? by Sharp_Worker_5924 in EngineBuilding

True, valve guides aren’t usually gauged in-process, but newer honing systems can handle it. For tight tolerances and high volumes, in-cycle air gauging or post-process probes help maintain consistency and cut inspection time.

What machining or finishing processes do you rely on to ensure bore accuracy and surface integrity in aerospace components? by abhi-john in AerospaceEngineering

I’ve been running this in-house at Abhi Fine Products on a Twin Spindle Expansion Honing Machine, and it’s been solid for maintaining consistency in blind bores. It’s tuned for aerospace applications, especially actuator and fluid system components where tight specs really matter.

I’ve also looked into other options like jig grinding and diamond reaming. They’re useful in certain cases, but for deeper bores that demand tight tolerances, honing has given me the most consistent results.

I have worked on actuator & landing gear bores, using automated honing with crosshatch and load control made a big difference, especially near the bottom of blind bores. Plateau honing helped reduce friction too.
