Industry: Oil & Gas
Project Duration: 14 Weeks
Component: 58T 2.5DP Bull Gear
PROJECT OVERVIEW
Lamond & Murray DEXIS was commissioned by a key player in the oil and gas sector to produce a precision-engineered bull gear. With a tight 14-week turnaround and strict AGMA quality requirements, this project demanded advanced gear cutting and grinding capabilities to meet both dimensional accuracy and performance standards.
THE PROBLEM
The client required a 58-tooth, 2.5DP bull gear manufactured to exact specifications, including high-precision gear geometry and surface finish. The gear had to meet AGMA quality grades for use in a demanding operational environment. Efficient material removal, followed by precision grinding, was essential to meet both deadline and performance targets.
THE SOLUTION
Lamond & Murray executed the job using a two-stage gear manufacturing process:
– Rough Gear Cutting: Material was rapidly removed using a single index roughing cutter on our P1000/1200 Gleason hobbing machine – an ideal approach for efficiently handling larrge gears while maintaining cutting integrity
– Finish Grinding: The gear was then transferred to our P1480G Gleason profile grinder for finish grinding. This stage ensured that the gear met the AGMA quality level required by the customer, with precision ground tooth geometry and excellent surface finish.
– Final Turning: Finish turning to the customer’s drawing specifications completed the process, delivering a fully machined and inspection-ready bull gear.
WHAT MADE THIS PROJECT STAND OUT
This job showcased Lamond & Murray’s ability to combine high-speed rough cutting with precision finish grinding—all performed in-house. The use of a single index roughing cutter drastically reduced machining time, while the profile grinding process guaranteed compliance with tight tolerances and high performance standards.
THE RESULT
The bull gear was delivered on time and to specification, with the customer expressing high satisfaction in both quality and turnaround. As a result, Lamond & Murray received repeat orders for the same component, further cementing our reputation as a reliable engineering partner to the oil and gas industry.
