machining & installation
Machining Onsite
CIP Composites are readily machinable by conventional machining techniques. As a general guide they may be treated as they would for soft metals such as aluminum or bronze, but machined (dry) without coolant. CIP materials are non-toxic, although it is advisable to use adequate dust extraction when machining.
For turning, tungsten carbide or diamond tipped tools should be used to obtain a fine finish. High speed steel tools can be used for machining where accuracy below 0.005 in. (0.12 mm) is not required and for small quantity production.

INSTALLATION GUIDELINES
Installation guidelines for your CIP materials
Freeze-Fit
Bearings do not become brittle during the freezing process. Liquid nitrogen is the most efficient method; in some cases dry ice or refrigeration may be used. Once bearing is frozen, and outer diameter is smaller than housing, block or hold the bearing in place. As the bearing returns to ambient temperature it will increase in size and the proper interference with the housing will be obtained.


Mechanically Fasten
Shoulders, bolt on rings, other rings, or keepers can be used to prevent the bearing from moving over time. Flat components such as wear pads can be retained by countersunk screws or metal inserts and located by keeper plates where high lateral or shearing loads are anticipated.
Press-Fit
Bearings should be fully supported over their loaded area, with uniform interference fit. A suitable lead-in chamfer should be provided in the housing and on the bearing diameter to assure proper start. The amount of force can be suggested to make sure there is adequate power available.


bonding
CIP Composites inherently bond with adhesives exceptionally well. Bearings can be designed for glue-in installation with a minimum clearance of 0.005 in. (0.127 mm). During installation, bearings should be retained on top and bottom. Wear pads can be retained with adhesives to many metallic surfaces. We can recommend adhesives.
Counter/Mating Surface
The counter surface finish of the mating operating component has a major effect on the performance of the composite. Surface finish should ideally be 16 – 32 RMS (0.4 – 0.7 μm) RA minimum and HRB 80. Suitable materials for shafts, thrust faces, etc., would be hardened steels or stainless. All mating surfaces should be free from cutting edges and lubrication grooves or holes.
