Out-of-round bores and off-center diameters jam assemblies. Learn roundness vs concentricity and how each is measured. BQUQ checks both by CMM per batch.
Drilling gives ±0.1 mm, reaming reaches H7, boring goes tighter. Match the hole process to the fit class. BQUQ quotes holes in 12 hours.
Nominal, measured, deviation, tolerance: a CMM report is simple once you know the columns. Catch bad parts early. BQUQ ships reports with batches.
Castings save cost at volume but add porosity risk and loose as-cast tolerance. Bar stock is faster and safer for small runs. BQUQ quotes in 12 hours.
Swiss lathes hold tight tolerances on small, long parts via a guide bushing. See when Swiss beats a conventional lathe. BQUQ quotes in 12 hours.
Accuracy centers parts on target; repeatability clusters them. Both set Cpk and scrap rate. Read both numbers before you approve. BQUQ quotes in 12 hours.
Anodizing grows, plating adds, heat treat moves parts. Every finish changes size and tolerance. Manage outsourced finishing risk. BQUQ quotes in 12 hours.
POM, PTFE, nylon and PEEK machine well but expand and deflect more than metal. See when plastic CNC parts beat metal. BQUQ quotes in 12 hours.
3-axis runs simple parts cheaper; 5-axis cuts setups and holds tolerance on complex geometry. Learn when the extra axis pays. BQUQ quotes in 12 hours.
Cut, tap or thread mill: each holds a different tolerance. Match the process to 6H, 2B or tighter. BQUQ machines threads, quotes in 12 hours.
6061 machines faster and costs less; 7075 is nearly twice as strong. Compare both before machining aluminum parts. BQUQ quotes in 12 hours.
Machining titanium to ±0.01 mm needs rigid setups and low cutting speeds. BQUQ machines Ti-6Al-4V and quotes drawings in 12 hours.
How small-batch CNC economics work: tooling avoidance, setup amortization, and per-part cost math for 50-500 piece runs. Source-direct from BQUQ, quote in 12 hours.
How to choose CNC tool holders by torque, runout and reach — plus what we see on parts quoted in 12 hours at BQUQ's ISO9001 Dongguan factory.
Export packaging for machined parts: foam, VCI, desiccant, crating and humidity control to protect tolerance and surface finish in ocean and air freight.
