Our machining expertise and equipment ensure that we 'fix it right the first time' and deliver the results you need every time you work with us.
CNC Boring & Honing
Honing is a process intended to perfect bore geometry and size by removing a minimal metal layer, while generating a finished pattern to provide optimum lubricant retention. The honing process produces extremely tight tolerances in straightness, roundness, size, and surface finish of cylindrical bores.
At Island D Automotive Machine, we have a cutting edge Rottler H85A CNC Automatic Vertical Honing Machine that offers an accurate and uniform crosshatch angle the entire length of the bore. This is achieved with machine feeding stones to specified load during the honing process and withdrawing stones before stopping. We understand that surface finish is critical and it can be hard to replicate consistently block after block. That's why we use the best machinery to deliver superior results to our customers.
Cylinder boring is the process of machining a cylinder to accept a larger diameter piston. Usually, cylinder boring is performed when the bore has become worn out or damaged. Cylinder boring must be done correctly and precisely. Any deviation in the process will cause premature failure of expensive engine parts or catastrophic engine damage. At Island D Automotive Machine, we have a Precision Rottler F5 Boring Bar (capacity 2" to 7") that is accurate down to .0002”, ensuring the cylinders are restored to a factory finish.
Island D. Automotive Machine has earned a province wide reputation for our Crankshaft Services.
We begin with cleaning, inspecting, and measuring the Crankshaft and compare these results against OEM specifications. Upon measuring and inspecting the condition of the bearing journals we will determine whether the Crankshaft is suitable for a regrind or if it only requires a polish before going back into service. Our most popular Crankshaft services are:
Crankshaft grinding consists of removing a small amount of damaged material from the rod and main journals to restore the surface finish back to a like-new condition. This in turn will make the Crankshaft journal smaller so a thicker bearing shell will need to be purchased to accommodate the material removed from the journal. Most Crankshafts are engineered to be about four times stronger than required, so removal of material does not affect future longevity. Max. distance between chucks: 64”
After the Crankshaft is ground to the appropriate size it is then polished. Polishing the journals of the Crankshaft to a smooth finish will ensure a long bearing life.
Sometimes a Crankshaft can be bent while in service. This is typically caused by extreme heat from a bearing failure or when the engine has been heavily overloaded. A Crankshaft with a failed bearing, and therefore an overheated bearing journal, should ideally be checked for straightness before being reground. A Crankshaft straightening press is used to straighten a Crankshaft and return it back to its original specifications.
The Flywheel often develops patterns of wear due to the excessive friction and heat over time. This wear and tear can cause vibration when the Flywheel is engaging and when the vehicle is accelerating.
In order to prevent any issues directly after installation on a new clutch, or later down the line, it’s important to get the Flywheel regularly resurfaced.
Engine Rotating Assembly Balancing
Whether you’re building a mild stock engine, a high-revving performance engine, or a slow-turning heavy-duty diesel engine, the importance of a high quality and precise balancing job is key.
Engine balancing will leave you with a smooth running engine with minimal vibration ensuring a long, trouble-free service life. Balancing also greatly improves bearing life as it drastically reduces side loads.
O-ringing involves machining a precise groove cut into the surface of the Cylinder Head and then the installation of a stainless steel O-ring. After this process the O-ring now adds a secondary seal to the head gasket at the fire ring area which can absorb warpage and still maintain a compression seal.
At Island D. Automotive Machine we have a wide range of cleaning services to restore your engine parts back to their factory finish and specifications.
Hot Tank: This process submerges the Cylinder Head into a caustic hot water solution that is capable of removing the heaviest oils, dirt and grime, while stripping most paints from the ferrous surfaces. The engine parts are submerged in the solution for many hours, allowing all the internal galleries and passages to be completely cleaned. A caustic hot tank does not remove the rust from ferrous items and is not safe for Aluminum. Ferrous engine components only.
Industrial Jet Clean: Solvent-free process using pressurized hot water and specialized industrial detergents with rust inhibitors to clean parts. Safe for Aluminum.
Industrial Ultra Sonic Cleaning: This cleaning service submerges components into the Ultra Sonic tank to remove foreign materials and contaminants. The sound waves create a gentle, yet powerful scrubbing brush action in the fluid that cleans all surfaces of debris, including deep pores and crevices.
Media Blasting: Cleaning process that utilizes pressurized air combined with the appropriate media to to remove foreign materials and contaminants on a wide variety of materials.
Cylinder Head Rebuilding & Resurfacing
Island D. Automotive Machine offers Cylinder Head cleaning via Hot Tank and Industrial Jet Clean. Please refer to the Cleaning services above for further description of these processes.
Pressure Testing: During pressure testing we block water outlets on the Cylinder Head and then put pressure on the Cylinder Head with compressed air. This process allows for us to find if the Cylinder Head is leaking.
Vacuum Testing: Vacuum testing valves confirms if the valve is sealing correctly with the valve seat.
Magnaflux: Utilizes fluorescent iron oxide particles and a strong magnetic field to locate cracks, seams, dents, or leaks in iron and iron-based alloy metals that would otherwise be impossible to see with the naked eye.
Resurfacing: Island D. Automotive Machine performs resurfacing with a state-of-the-art Rottler CNC surfacer. Super Fine Surface Finish – Direct Drive precision ball screws and linear slideways combined with infinitely variable speeds and feeds allows a surface finish as low as 2Ra to 6Ra. Today's MLS (Multi Layer Steel) head gaskets require a super fine finish to properly seal combustion pressure and oil and water.
We offer precision connecting rod machining and reconditioning services. We have the equipment to work on connecting rods of all sizes from diesel and natural gas engines. A rigorous examination process is performed to determine their re-usability, sizing and straightness. We then apply new bushings that are cut to size, providing a smooth surface ready to return to its application.
The valve face is machined using a Rottler Centerless Grinding System, allowing for improved sealing, better heat transfer and reduced mechanical stresses on valves. Results are extremely accurate: valve stem to valve seat run out is less than .0002".
Sleeves can be used to restore a particular bore size to factory specifications and dimensions if a Cylinder has been too badly worn or damaged.
Cylinder sleeves or cylinder liners are often divided into two types: Dry Sleeves and Wet Sleeves. This is determined by whether the Sleeve is in direct contact with coolant (wet) or not (dry).
