Precision Profile Wheels
Electroplated diamond and CBN precision profile grinding wheels from DK Holdings are engineered for high-accuracy creep feed grinding applications. Recognised as pioneers in the development of diamond form wheels for this process, the company originally introduced the concept for producing hard metal inserts using precisely formed diamond and CBN tooling.
Designed for demanding production environments, these profile wheels provide exceptional dimensional stability and repeatable accuracy.
Material Compatibility
Diamond wheels are recommended for:
Tungsten carbide
Technical ceramics
Ferrites
Glass
Carbon materials
Reinforced plastics
Nimonics and other abrasive substrates
CBN wheels are suited for:
High-speed steels
Tool steels
Hardened ferrous materials
Applications
Typical applications include:
Carbide insert grinding
Circular form tooling
Crushing blocks
Thread forms
Broach grinding
Cam grinding
Gear form grinding
Specialised high-precision profiles
Ultra-Accurate Tolerances
Dimensional tolerances of ±0.005 mm and angular tolerances of 10 minutes are consistently achieved. Such accuracy ensures reliable repeatability across long production runs.
Multiple Profiles Per Wheel
Where profile geometry allows, more than one form can be incorporated into a single wheel. This approach significantly extends service life — often doubling or tripling usable output — while only marginally increasing initial cost. Guidance is provided during quotation where this solution is viable.
Machine & Coolant Requirements
Optimal results are achieved when used with a creep-feed grinding machine providing sufficient coolant flow. A minimum supply of 40 litres per minute is essential. However, systems delivering up to 135 litres per minute, such as centrifuge-assisted coolant delivery, substantially enhance wheel life and surface finish quality.
Installation & Run-Out
Each wheel is supplied with either a clocking flange or groove depending on thickness. Proper truing to these datum faces is critical. Total run-out should not exceed 0.003 mm radially or axially.
Profile Design & Clearance Compensation
Clearance angles, helix angles, and rake geometry are fully compensated within the wheel design. Wheels are manufactured from customer-supplied inserts or technical drawings. Where side clearance is required, split profile wheels can be supplied.
Grit Selection
Grit size selection depends on:
Profile tolerance requirements
Minimum radii
Profile depth
Our technical team will recommend the most appropriate specification for your application.
Repeat & Replating Service
Repeat orders are offered at a significantly reduced cost compared to original manufacture. In addition, a strip and replate service is available, restoring performance while reducing overall tooling expenditure.
