cnc turning · hillsborough, new jersey
Our CNC turning services run in Hillsborough, New Jersey, on four CNC lathes and a Mori Seiki mill-turn centre. Turning runs to 28″ diameter and 60″ long on the Okuma LB4000EX, and to 14″ diameter and 83″ long on the Doosan Puma 300XLY for long shafts. Tolerances under .001″ are standard work, and we hold ±.0005″ where the print calls for it. Three generations of machinists stand behind every part.
Hubs, gear blanks, flanges, rolls and housings to 28″ run on the Okuma. It is a 50-horsepower machine that takes a heavy cut in 4140 without complaint. Each diameter is checked against the drawing before the part comes out of the chuck.
Drive, pump and rotor shafts to 83″ run on the Puma, held between centres so the diameters run true end to end. Bearing journals are ground in house after turning. Longer shafts go to the large lathe department, which takes work to 170″ between centres.
Parts with off-centre holes, flats or keyways go on the Mori Seiki NTX2000 mill-turn. The turned diameters and the milled features come off the same setup, in true relation to each other. That saves a second setup and the error that comes with it.
There is no minimum quantity. A single replacement part runs on the same lathes as a production run. Where there is no drawing, we reverse engineer the worn part and turn a new one. Parts that need a keyway, a ground journal or a honed bore are finished here before they ship.
Turned parts leave Hillsborough for plants across New Jersey: Bridgewater, Somerville, Flemington, Edison, Piscataway and Trenton, and the industrial corridor through Newark, Elizabeth, Jersey City and Paterson. Customers in Somerset, Hunterdon, Middlesex and Mercer counties often drop parts off and collect them by hand. Further out, parts ship by truck to eastern Pennsylvania, New York, and across the United States, Canada and Mexico.

Four CNC lathes and a mill-turn centre, each suited to a different kind of part. Work that is too big for them goes to the large manual lathes.
28″ diameter × 60″ long, 50 hp. The large-diameter machine for hubs, flanges, rolls and housings.
14″ diameter × 83″ long. The long-shaft machine, turning between centres so the diameters run true.
Mill-turn to 24″ × 60″, with simultaneous 4 and 5 axis milling and drilling in the same setup.
20″ diameter × 54″ long. Precise turning for small and large quantities.
18″ diameter × 45″ long. Fine finishes on shafts, adapters and sleeves.
Vertical turning to 60″ and horizontal work to 32″ × 170″ on the large lathes.
Extruder parts. Screw blanks, adapters, barrel internals and melt piping for single and twin-screw lines. See extruder components.
Industrial drive parts. Hubs, gear blanks, couplings and shafts for reducers and power transmission, often alongside a gearbox rebuild.
Defence and aerospace. Turned components to print. Zala Machine Co. is ITAR registered.
Pump, blower and mixer parts. Shafts, rolls, spools, sleeves and flanged bodies, turned to print, one piece or a run.
Alloy steel, 4140 and 4340, including turning after heat treat where the part has to stay dimensionally stable. Stainless in the 300 and 400 series, 15-5 PH and 17-4 PH, for food, pharmaceutical and marine work. Titanium and Inconel, with rigid setups and the right feeds for alloys that punish tooling. Aluminium, brass and bronze, turned fast and held to size.
A turned part is rarely finished when it leaves the lathe. It may need a keyway milled, a journal ground, a bore honed or a flange welded on. All of that happens here, so the part is not shipped between shops between operations.
Bearing journals are finished on the grinder, and bores go to bore honing when the finish or size calls for it. The shaft machining page covers that side of the work in detail.
Every part is checked against the print before it ships, with a Keyence portable CMM, micrometers, bore gauges and depth mics.

| Okuma LB4000EX | 28″ diameter × 60″ long — 50 hp, the large-diameter machine |
| Doosan Puma 300XLY | 14″ diameter × 83″ long — the long-shaft machine |
| Mori Seiki NTX2000 | 24″ × 60″ mill-turn, simultaneous 4 and 5 axis |
| Daewoo turning centre | 20″ × 54″ |
| DMC DL 30 | 18″ × 45″ |
| Beyond the CNC | vertical turning to 60″; horizontal to 32″ × 170″ between centres |
| Tolerance | under .001″ as standard, ±.0005″ to print |
| Finishing in house | shaft grinding, bore honing, keyways and splines, welding and polishing |
To 28″ diameter and 60″ long on the Okuma LB4000EX, and to 14″ diameter and 83″ long on the Doosan Puma 300XLY. Those are two different machines — the big diameter and the long length do not come together on one CNC lathe. Beyond that, the manual department turns vertical work to 60″ and horizontal work to 32″ by 170″ between centres.
Yes. Shafts to 83″ run on the Puma between centres, and longer ones go to the Poreba at 170″. Bearing journals are ground in house. The shaft machining page covers sizes, materials and the types of shaft we make.
Yes. The Mori Seiki NTX2000 is a mill-turn: turning to 24″ by 60″ with simultaneous 4 and 5 axis milling and drilling in the same setup, so off-centre holes, keyways and flats come off in true relation to the turned diameters.
Under .001″ is standard work, and we hold ±.0005″ where the print calls for it. Every part is checked against the drawing before it ships.
Yes. 4140 and 4340 are turned after heat treat when the part has to stay dimensionally stable, and hardened journals are finished on the grinder.
Carbon and alloy steel, 4140 and 4340, 300 and 400 series stainless, 15-5 PH and 17-4 PH, titanium, Inconel, aluminium, brass and bronze. Tell us the material with the print and we will source it, or machine stock you supply.
No. Single replacement parts and one-offs run on the same lathes as production runs. Tell us the quantity with the drawing and we will quote it.
Hillsborough, New Jersey, in Somerset County — an easy drive from Bridgewater, Somerville, Flemington, Edison, Piscataway and Trenton, and from the corridor through Newark, Elizabeth, Jersey City and Paterson. Turned parts also ship by truck across the United States, Canada and Mexico.
Turned parts are often milled, ground, honed or welded before they ship. These are the services that sit alongside the lathes.
