  SPUR GEARS AND CHAIN SPROCKETS
Our sophisticated gear cutting machines have a gear cutting capacity of 5.7m in
diameter by 500mm face width. Our gear hobbing machines have a capacity of 2m
in diameter and a face width of 730mm and 20 module pitch.
 
SINGLE HELICAL GEARS
Capacity generally as specified under Spur gears, but with reduction in face width
as helix angle increases.
DOUBLE HELICAL GEARS
Sunderland system: fixed 30 helix angle double helical gears up to 1.5m diameter,
with a face width of 305mm and 16 module pitch.
Hobbed double helical: on our hobbing machines we gear-cut a wide range of
double helical gears up to 2m diameter, with a face width of 730mm, 18 module
pitch and helix angle to suit customer requirements.
Maag: Double helicals and special pitch gears up to 5.7m in diameter and 500mm
face width.
GEAR GRINDING - SPUR AND HELICAL GEARS
On our Hofler, Raishauer & Niles Gear Grinding Machine we are capable of grinding Gear Teeth Flanks on Spur and Helical gears up to 800mm in diameter and a maximum face width of 230mm. Pitch range 2 module to 14 module.
LEAD AND INVOLUTE CHECKING
Capacity to check lead and involute form of Spur and Helical gears up to 800mm
in diameter.
WORM THREAD GRINDING
For worm shafts requiring a high standard of finish particularly after heat treatment.
We are able to thread Grind Worm Flanks to meet this requirement.
INTERNAL GEARS
We gear-cut Generated Gear Teeth up to 2200 pitch diameter, with a face width of
200mm and 10 module pitch. Larger internal gears are gear-cut using a form
cutter.
BEVEL GEARS
Spiral: Gears up to 500mm and 12 module pitch.
Straight: Straight tooth bevel gears up to 1525mm pitch diameter with a face width
of 320mm and 25 module pitch.
INTERNAL KEYWAYS & SPLINES
Straight sided and involute splines up to 90mm wide with a length through bore
of 710mm.
EXTERNAL SPLINES
Straight sided and involute splines on shafts up to 3 meters in length.
GEAR TYPE COUPLINGS
Manufacturers of gear couplings with barrelled teeth for applications where there
is an amount of misalignment between driving and driven shafts.
GENERAL ENGINEERING
CNC Turning, conventional turning, milling, drilling and slotting.
RACKS
We gear-cut racks from 1 module to 8 module pitch.
GEARBOX RECONDITIONING / REFURBISHING
We are able to recondition all makes and most sizes of Industrial gearboxes.
