Machine Shop, Precision Machining and Metal Fabrication
Full machine shop facilities.
To provide maximum quality service, Cariboo Chrome and Hydraulics is continually upgrading machinery to state-of-the-art equipment.
With the purchase of a new computer controlled lathe with a 28" swing and 80" between centers, we are capable of machining with tremendous accuracy in both small and large quantities.
Fabrication and Rebuilding
Complete repair of all makes of forklift masts and carriages. We also repair and manufacture loader booms, bell cranks and excavator buckets.
Please feel free to call for more information.
Precision Grinding
External and Internal Grinding
In addition to precision grinding of basic cylindrical forms, Cariboo Chrome and Hydraulics can grind parts with steep tapers.
Spray welding, using high nickel based alloys, can increase hardness and wear resistance to working surfaces and edges, especially in high temperature or adverse environments. In addition, worn parts can be reconditioned by building up worn surfaces, and then machining them to original specifications. Various hardness ranges are possible depending on the application.
Hard surface spray welding is typically used on areas that will need to endure regular wear and abuse. Treating these areas will allow the part to last longer and perform better.
At Cariboo Chrome, we understand the needs of a wide range of markets, such as the mining, pulp and paper, forestry and oil and gas industries. We work with all types of metals, including carbon steel, stainless steel, alloy steels, aluminum and brass, in thicknesses from sheet metal to plate.
Submerged arc welding differs from other arc-welding processes in that a blanket of fusible, granular material - commonly called flux - is used for shielding the arc and molten metal. The arc is struck between the work-piece and a bare wire electrode, the tip of which is submerged in the flux. Since the arc is completely covered by the flux, it is not visible and the weld is run without the flash, splatter, and sparks that characterize the open arc process.
Benefits:
- Used with all types of joints
- Permits welding a full range of carbon and low-alloy steels
- Permits welding of some high-alloy, heat treated and stainless steels
- Favored process for rebuilding and hard surfacing
- Good ductility, impact resistance and uniformity in bead appearance
- Mechanical properties that are at least equal to those of the base metal are consistently obtained
Coldspray
The most versatile powder delivery systems with the ability to apply both fused and non-fused coatings. High spray rates in all positions, including internal bores.
Benefits:
- Enhanced resistance to abrasion and erosion
- Thermal barrier coatings
- Galvanic protection of iron and steel
- Dimension restoration
- Corrosion protection at elevated temperatures
- Friction wear resistance
- Improved bearing surfaces
Hard Facing
Fusion hardfacing is a process by which weld materials, with superior properties than the substrate, are applied to the substrate. Common hardfacing techniques include arc, torch, and other processes.
Hot Spray
This system deposits fused metallurgical bonded coatings to a wide range of base metal types. Excellent for applications involving cast iron repair, casting salvage, mold repair, screw and fan protection and valve repair.
Benefits:
- Precision coatings on fine edges
- Blanket coatings on cylindrical parts in rotation or to flats
- Coatings to a variety of base metals
- Metal powders are bonded to the base metal with minimal distortion and warping
- Coating formulas available to protect against abrasion, erosion, corrosion, impact and point loading
- Coatings ranging from 0.003" to 0.25" (.07 to 6 mm) can be applied in a single pass
Spray and Fuse
For spray and fuse, the powder is first deposited on the metal surface, then heated further to form a continuous hard surface layer. Fused coatings are a useful tool in the repair of shafts such as valve stems and pump plungers. Coatings thick-ness may exceed 0.060" without loss of bond strength. Deep scoring in packaging areas that had been chrome plated initially may operate better with fused coating because of the added protection from corrosion provided by the dense, fused overlay and the added bonus of a metallurgical bond.
Hydraulic Cylinder Repairs & General Machining
Fabrication and rebuilding of any type of hydraulic cylinders including rerods and retubes.
Honing
Our reconditioning service includes internal and external grinding, honing and chroming, on cylinders and piston heads.
Hard Chrome Plating
Hard chrome plating deposits are intended primarily to restore dimensions of undersized parts and to improve resistance to wear, abrasion, heat or corrosion, seizing and galling. Hard chrome can be applied to carbon alloy steel, iron castings, copper alloys, and all types of stainless steel and aluminum alloys.
Benefits:
- Build up lost metal or restore expensive machined parts
- Can be ground, honed and polished, lapped or finished
- Extreme hardness
- Low coefficient or friction
- Corrosion resistant
- Abrasion resistant
- Wear resistant
