Customer needs are orders; overcoming difficulties and striving for excellence—A record of the emergency delivery of the H1 Camshaft
Release Date:
16-12-20
In early winter, November brings a bustling scene to the Camshaft Precision Machining Workshop, where all production lines are operating at full capacity to ensure on-time delivery for customers. Just as sales received another urgent request, Weichai’s H1 Camshaft project suddenly placed a bulk order for 600 units, with a requirement to have 1,000 units ready by December. This is a brand-new project that, over the past two years, has only seen a few dozen engines trial-assembled—yet it has now been abruptly launched! To make matters worse, this steel camshaft project is still in the prototype stage; internally, the company doesn’t even have the raw material—steel billets—nor the dedicated production lines or specialized equipment. What’s more, the existing steel camshaft production line is already running at full capacity, leaving us completely unprepared. What do we do when we “want the gun” but don’t have the gun, and “want the bullets” but don’t have the bullets? Customer demand is command—no matter the circumstances, we must find a way to deliver. The Camshaft Production Management Team has always refused to accept defeat. From the general manager down to frontline workers, production, technical, and workshop management personnel worked together to devise solutions, meticulously planning each operation one by one, making full use of any spare time within existing processes, seizing every available opportunity, and even outsourcing certain operations to external contractors when necessary. Since the dedicated drilling machine had not yet arrived, and the original machining center plan would have taken too long to drill the oil holes on the camshaft body, we quickly reorganized the process: using CNC milling machines to drill the oil holes separately. From initial concept to temporary fixture setup and debugging, we completed the adjustment in just one day. After drilling the oil holes, burrs and rolled edges remained on the inner walls, so we manually scraped them one by one using chamfering tools and gun drills. For burrs and metal chips left inside the through-holes of the camshaft body, the existing cleaning machine couldn’t remove them completely. We first used long brushes dipped in kerosene to scrub the holes, then wrapped deep-hole inspection gauges with clean wiping cloths and repeatedly inserted them into the holes to scoop out the remaining debris. Yet tiny metal particles still lingered inside, and several rounds of particle-size inspections failed to meet the standards—while sales was already waiting for shipment. Just when everyone was at their wits’ end, someone suggested, “Why not try flushing the internal bores with a high-pressure water jet?” What a great idea! We immediately moved the camshafts to the cleaning room next to the washing, recycling, and packaging area, prepared the cleaning solution, used the high-pressure water jet to flush the internal bores first, then flushed each oil hole individually, and promptly sent them off for cleanliness testing. The results were合格! Everyone finally breathed a sigh of relief and immediately plunged into special cleaning procedures… It was precisely because the technical and production management teams thought creatively, pooled their wisdom, and took hands-on action that the company successfully completed the first emergency delivery batch of H1 camshafts.
In early winter November, the Camshaft Precision Machining Workshop was bustling with activity, as all production lines were operating at full capacity to ensure on-time delivery for customers. Sales once again conveyed a surge in demand: Weichai H1 Camshafts suddenly required a bulk order of 600 units, with a target of 1,000 units by December. This is a new project that, over the past two years, has only seen a few dozen engines undergo trial assembly—yet it has now been abruptly launched! It should be noted that this steel camshaft project is still in the prototype stage; internally, the company does not even have the raw material steel billets, nor the corresponding production lines or specialized equipment.

What if you want a “gun” but there’s no “gun,” and you want “bullets” but there are no “bullets”? Customer demand is command—no matter the circumstances, we must find a way to deliver. The Camshaft Production Management Team has never been one to give up. From the general manager down to frontline workers, all production, technical, and workshop management personnel worked together to devise solutions, meticulously scheduling each operation and making full use of any spare time within the process cycle, seizing every available opportunity. For certain operations, we even outsourced processing to external partners. Although the dedicated drilling machine had not yet arrived, and the original machining center plan would have taken too long to drill the oil holes on the shaft body, we devised a solution to split the operation: using a CNC milling machine to drill the oil holes separately. From initial concept to temporary fixture setup and debugging, we completed the adjustment in just one day. After drilling the oil holes, burrs and rolled edges remained on the inner walls, so we used chamfering tools and gun drills to manually scrape them off one by one.

The results were合格! Everyone finally breathed a sigh of relief and immediately plunged back into special cleaning procedures… It was precisely because the technical and production managers thought quickly, pooled their wisdom, and personally got involved that the company successfully completed the urgent delivery of the first batch of H1 Camshafts.
