Turning
CNC vertical turning for large diameters, CNC parallel turning for long parts, and conventional turning machines for supporting operations.
Scope
Machining grouped by operation
BRUVAL's machining capability covers turning, milling, and grinding so the capacities have meaning instead of appearing as loose numbers.
Milling
5-axis CNC milling for large travel envelopes and complex surfaces.
Grinding
Corrective geometry work and surface completion for final dimensions and visual condition.
Machining route
Plan the part before choosing the machine
Machining decisions should start with the component function, not only the available machine envelope. The route depends on weight, material, welded or heat-treated condition, datum references, tolerances, and which features control fit in the final assembly.
Review data
Confirm drawings, model, photos, material, dimensions, weight, current condition, and critical fit features.
Set datums
Choose reference faces, bores, journals, centerlines, or fixture points before rough machining begins.
Sequence work
Plan turning, milling, grinding, drilling, welding, heat treatment, or stress relief in the order that protects final geometry.
Control risk
Account for distortion, hard spots, welded zones, access limits, clamping marks, and measurement points.
Verify release
Check dimensions, surface condition, runout, flatness, bore fit, and documentation before delivery.
Inquiry data
What helps BRUVAL evaluate machining work
- Drawing, 3D model, sketch, or photos showing all functional faces and interfaces
- Overall length, width, height, diameter, approximate weight, and handling constraints
- Material grade, hardness, heat-treatment state, weld repair areas, coating, or hard-facing
- Critical tolerances, datum references, bores, journals, flatness, runout, surface finish, and threaded features
- Operations required: turning, milling, grinding, drilling, welding preparation, heat treatment, assembly, or inspection
- Quantity, target delivery date, shutdown window, certificate requirements, and final documentation needs
Turning
Large vertical and parallel turning
BRUVAL works with CNC turning machines on parts up to 7000 mm diameter with CNC vertical turning and up to 16000 mm length with CNC parallel turning. The section is also equipped with conventional turning machines.
Milling
5-axis CNC milling
All milling operations are performed using 5-axis CNC milling machines travelling up to 16000 x 3000 x 2000 mm.
Grinding
Corrective and completion adjustment
BRUVAL performs corrective adjustment to improve geometry and final dimensions, plus completion adjustment for visual look and surface condition.
- CNC cylindrical grinding up to 7000 mm outer diameter
- CNC cylindrical grinding up to 16000 mm length
- CNC surface grinding up to 12000 x 2400 x 2000 mm
