What Our Customers Say
In-House CNC Service has built its reputation one service call at a time across Southern California’s manufacturing corridor. The following reflects the kinds of feedback we consistently receive from shops we serve u2014 from aerospace suppliers in Chatsworth to automotive parts manufacturers in Ontario to medical device shops in Irvine.
“Back in production the same day”
A Riverside-area aerospace component supplier running a Mazak Nexus 250-II experienced a spindle fault during a production run on a Monday morning. The machine threw a spindle amplifier alarm and would not restart. Their production coordinator called In-House CNC at 7:30 AM and Jason arrived by 10:00 AM with the diagnostic equipment and a spare amplifier module.
The fault was confirmed as a FANUC spindle amplifier failure u2014 a common failure mode on that series. The amplifier was swapped, parameters verified, and the machine was back in production by 1:00 PM the same day. “We would have been down for a week waiting for OEM service,” the shop foreman noted. “Having someone show up same-day with the right part is a completely different experience.”
“Clear about what it would cost before starting”
An Ontario automotive parts supplier running a Doosan Puma 3100 experienced axis drift and abnormal vibration during a turning operation. They had called the machine’s dealer first but were quoted a two-week wait for a service visit. In-House CNC was on-site within 24 hours.
The diagnosis revealed worn linear guide bearings on the X-axis. Jason explained the findings, provided a written estimate, and confirmed parts availability before starting the repair. The job took two days u2014 bearing replacement plus a full geometry verification. “He told us exactly what it would cost before touching anything. That kind of transparency is rare,” the plant manager said.
“Saved us from making a bad decision”
A San Bernardino job shop was considering replacing a 2008 Haas VF-3 after experiencing recurring servo faults. They called In-House CNC for an inspection before committing to a new machine purchase. The diagnosis revealed a failing servo drive on the Y-axis u2014 a $600 repair u2014 rather than a systemic mechanical problem. The machine was repaired and returned to full production.
“We were about to spend $80,000 on a new machine for a $600 problem,” the owner said. “Getting an honest diagnosis before making that call was worth everything.”
