Red Deer, AB - Manufacturing Reciprocating Pumps -> Skiving

Skiving & Burnishing Machines

• Three machines do all the skiving
• Barrels: SupraHard, Suprachrome, Brass Chrome, Nickel Carbide, and seating nipple material
• Material removal prior to heat-treating or chrome plating
• Removal of metal is done by a rotating head with double carbide inserts on insertion while rotating rollers roll off the peaks during back burnishing operation
• Removal rate of 0.0012”per side (average)
• Lengths up to 36 feet and 4.75”diameters
• Finish can be up to 1 µin (we average about 4 µin, which is twice as smooth as honing)

Advantages

• Very close tolerances (+/- 0.0005”)
• Improved SupraHard barrels due to skiving out the decarburized sections on the ID
• Feed rates and production are greater vs. honing
