Zala Machine is a top precision bore honing services supplier. We provide high quality honing services to finish ID bores that require a tight tolerance with a high quality finish. Regularly we hold tolerances of under .0005″ with finishes in the range of 8 rms. Utilizing top of line Sunnen equipment our honing shop finishes bores from under 3/8″ diameter up to 24″ diameter. With tube lengths up to 124″ long.
The honing process utilizes rotating stones to cut a perfect circular bore. With this process we are able to closely control size and leave a mirror finish that cannot be achieved with any other process. The parts that we hone are used in many different applications including hydraulic cylinders, engine blocks, aircraft landing gear and many many others. Basically any application that requires a precision smooth bore will require precision bore honing to get it to the required size, tolerance and surface finish.
Most machine shops have to outsource their honing, adding weeks to your lead time and increasing the risk of errors. At Zala Machine Co., our honing department is fully integrated with our CNC turning and milling departments.
This synergy allows us to offer two distinct paths for your project:
Complete Part Manufacturing: We handle the entire process—from sourcing raw material and rough machining to heat treating and final precision honing. You receive a finished, certified component ready for assembly.
Specialized Finishing Services: Already have a part machined? With our precision bore honing services we specialize in finishing tight-tolerance bores that other shops simply can’t hit, delivering superior surface finishes and corrected geometries.
Our honing department works in tandem with our quality control lab to ensure that every bore meets your exact technical requirements.
Geometric Correction: We eliminate taper, out-of-roundness, and bell-mouth issues in parts we machine from scratch or parts sent to us for finishing.
Superior Surface Finishes: We achieve custom finishes ranging from a rougher 64 Ra finish for heavy lubrication to a ultra-smooth 4-8 Ra finish for high-pressure seals.
Tight Tolerances: We routinely hold internal diameters to within +-.0005″ on larger bores and down to +-.0001″ on smaller bores.
Stop splitting your projects between machining vendors and honing specialists. Leverage our fully integrated shop synergy to reduce lead times, eliminate extra shipping costs, and ensure single-source accountability from raw material to final finish.
