build-to-print machining · hillsborough, new jersey
Most of the work in our Hillsborough, New Jersey machine shop begins with a customer’s drawing. Machining to print is the core of what we do. Plant engineers, maintenance managers and purchasing agents send us an RFQ with the drawing package, and we deliver a finished, inspected part made to that print. We work from PDF prints, DWG and DXF files, and IGES and STEP solid models. When no formal drawing exists, we work from a photo of a hand sketch, and many of the parts we have shipped over the years started exactly that way.
Every RFQ is reviewed the same or next day, and we let you know promptly whether we will be quoting the job. When we quote, the price reflects the complete job. That includes the raw material, whether we source it or you supply it, and every outside process the drawing calls for, including heat treating, plating, balancing and surface finishing, coordinated through our vendors. It also includes our own CNC and manual machining time and a lead time we are confident we can meet. If the part is needed to get equipment back into service, tell us when you send the RFQ and we will schedule the work to match. Simple parts are typically quoted in less than a day. A large drawing package can take up to a week to review and quote accurately.
Once we receive your purchase order, we manage the job from start to finish. Parts are turned on our CNC lathes, vertical turret lathes and long-bed manual lathes. Milling and drilling are done on our Mori Seiki NTX2000 5-axis mill-turn. Gundrilling, bore honing and shaft grinding are all done in house, so your part stays under one roof. We machine 4140 HT, 15-5 PH and other stainless steels, Inconel 718, titanium and bronze, and we routinely hold tolerances under .001″. Every part is inspected against the print using a Keyence portable CMM, micrometers and bore gauges, and surface finish is checked on a profilometer. There is no minimum order quantity: we produce single replacement parts and spares as well as production runs in the thousands. Material certifications, dimensional inspection reports and first article inspection are provided on request. We will sign a non-disclosure agreement to protect your drawings and designs, and Zala Machine Co. is ITAR registered.
From a hand sketch: a stepped replacement shaft with a threaded section and bearing fit.
From a drawing: a flanged die cone with bolt flange, tapped holes and ports.
From a solid model: a flanged die body with helical grooves and a port pattern.
A made-to-drawing job follows the same six steps every time, whether it is a single replacement part or a production run.
Email the complete drawing package: drawings or models, revision, material, quantity, finish and treatment requirements, and the date you need the parts.
We review the package the same or next day and let you know whether we will be quoting the job.
We price the material, sourced by us or supplied by you, and every outside process the print calls for: heat treating, plating, balancing and surface finishing.
We work out our CNC and manual machining time and the best lead time we can meet, including emergency scheduling when equipment is down.
Your quote arrives in less than a day for simple parts and within a week for large drawing packages. Approve it and send the PO.
We machine to your drawings and models, inspect every part against the print and control the job from start to finish.
We quote and machine from every common drawing and CAD format. If your file type is not listed, send it with your RFQ and we will confirm we can work from it.
Dimensioned prints, including multi-sheet drawing packages with revisions and notes.
AutoCAD drawings and 2D profiles, read directly from the file.
Surface and wireframe geometry exported from CAD systems of any age.
3D models, supplied on their own or alongside the dimensioned print.
A clear photo of a dimensioned hand sketch. Many of the parts we have shipped started this way.
Material, quantity, drawing revision, finish, heat treatment or plating requirements, and the date you need the parts.
Check your part against the machines it will run on. If it sits outside these, send the drawing anyway and we will tell you whether it is a job for us.
