Gear machining is the process of obtaining the specific structure and accuracy of gears by mechanical means。
We offer hobbing, shaving, milling, grinding, Archimedes worm gear forming, secondary envelope worm gear and worm gear forming, and large gear manufacturing.
SPP manufactures custom gears for a wide range of applications in power transmission, gearboxes, oil, gas and petrochemicals, lifts, motor sports, aircraft seating, robotics, nuclear, defence, railways, industry and more.

Gears from 1.5mm – 950mm dia. - Max. pitch = 8 Mod (3DP)
Internal Gears - Max. pitch = 6 Mod (4DP) Max. face width = 125mm (5″)
High Precision Gears up to 950mm dia. - 1 – 15 Module. Max. face width = 720mm
Grinding of gears up to class 5 accuracy.
Grinding of splines to a tolerance of 0.002.
Gear machining FAQ's
Spur/helical gears, spline & gear shafts, worm shafts & worm wheels, timing wheels, sprockets, idlers, rack & pinion, etc.
We are generally able to produce gears within Class 4 accuracy.
Gear forming requires tools of the appropriate modulus. We have general integer tools, special moduli require custom-made tools.
Spline shafts and spline bushings can achieve a mating clearance of 0.003, using wire-cut spline bushings and ground spline shafts.

SPP Industry Ltd.
In the 1990s, SPP Industry Ltd was one of the first manufacturers to establish CNC machining in China. The company has now established five major machine parks in China, with significant achievements in the areas of 5-axis machining, precision grinding & honing, gear machining, large parts machining, custom tungsten carbide and new material development respectively.
