In order to remain competitive in this global marketplace many companies look to automation for long term cost savings, to maximize throughput, and to make their manufacturing process world class. Whether you need to automate existing equipment or new equipment we have a solution. Assembly also plays a big role in today’s manufacturing. We work with suppliers and OEM’s to assemble Automotive Components, Plastic Components, DPF Components, Medical Components, Electronic Components, and more. From simple manual assembly stations to fully automatic lines KAR Enterprises can help!
Assembly Automation & Turnkey Provided By:
Superfinishing or microfinishing utilizes tape or stones to remove the amorphous layer which forms on the component as a result of high machining temperatures and working pressures. By removing the amorphous layer you expose an intact, stable material structure. The only way to guarantee a long service lifetime and minimize wear is to produce an absolutely perfect surface finish. Typical components that use Superfinishing are Crank Shafts, Cam Shafts, Bearings, Anti-Fritcion Bearings, and Medical Devices.

There are 3 main types of leak testing used for different components.
Pressure Decay Leak Testing is when you seal off part openings and pressurize the part typically with air or helium. This test looks for the decay/degradation of the pressure over time which gives you the components leak rate.
Vacuum Leak Test: Is very similar to Pressure Decay Leak testing with sealing off the part openings and then using a vacuum to pull the air out of the part. The test looks for the vacuum pressure to decrease over time which gives you the components leak rate.
Mass Air Flow Test (Flow Test): Mass Air Flow Testing is generally used for parts with high leak rates. This test pressurizes circuit/channels within the part with air and tests the flow rate through the channels. It checks for blockages, incomplete holes, etc.
Functional Testing: Functional Testing can be used to test a wide range of products including motors, pumps, and electrical components. A functional test machine operates the part as it would be in use and it tests that it functions properly.

Machining Centers are CNC machines that can perform milling, drilling, tapping, and boring operations within the same machines utilizing a variety of tools. KAR Enterprises offers our customers specialty machining centers that have multiple horizontal and vertical spindles along with automatic tool changers. These special machining centers can help manufacturers increase throughput, reduce multiple part handling operations, increase part accuracy, and provide a small footprint.
Machining Centers Provided By:
Multispindles are CNC or CAM driven lathes in which you have between 5-8 spindles each holding a part. The work sequence is then divided across the different spindles so that at each different spindle a different machining operation is being completed. After an operation is completed the spindles index, moving the part to the next operation and completing one part each index. Multispindles are best used for high volume applications, maximizing throughput, and for high concentricity parts.
Multispindle Lathes Provided By:
In their simplest form Rotary Transfer Machines are modular systems consisting of horizontal and vertical spindles rigidly mounted around an indexing table. These machines generally consist of 6 to 16 stations where the part indexes around the table and a different feature is machined into the part at each station. Rotary Transfer Machines are best utilized for high volume applications, maximizing your throughput, and very fast cycle times.
Rotary Transfer Machines Provided By:
Turning Centers also known as lathes hold a cylindrical part on one or both ends and rotate the part. A tool Turret with multiple static tools then passes along the part surface cutting the desired profile in the piece. More advanced Turning Centers allow you to stop the part from rotating and use “Live Tooling” to drill, tap, and mill features into your part.
