Valve Seat Tooling & Valve Seating Cylinder Heads

VALVE SEAT TOOLING

Advanced Cutting Tool Systems Valve Seating Cylinder Heads provide exceptional tool repeatability and are compatible with all valve seating machines. Advanced Cutting Tool Systems offers in-house, turn-key capabilities for superior quality assurance.

At Colonial Tool, we provide custom solutions for your unique valve seat tools. Our top-quality tooling allows for reduced set-up times and is optimized to require less frequent sharpening or cutting edge replacement. This means less downtime, which in turn gives you increased productivity and efficiency.

The end result is higher throughput and a lower cost per piece. When you multiply reduced valve seating cutting time per engine by the number of engines you produce per month or year, the savings start to add up. In the high-paced engine production industry, you can't afford to run slower speeds and suffer higher rejects than the competition. Your customers need reliable and consistent valve seating every single time. Choosing the right valve seating tools goes a long way to guaranteeing the quality of your machining operations.

The valve seat in an internal combustion gasoline or diesel engine is the surface against which an intake or an exhaust valve rests during the portion of the engine operating cycle when that valve is closed. The valve seat is a critical component of an engine in that if it is improperly positioned, oriented, or formed during manufacture, valve leakage will occur which will adversely affect the engine compression ratio and therefore the engine efficiency, performance (horsepower), exhaust emissions, and engine life.

Valve seats are often formed by first press-fitting an approximately cylindrical piece of a hardened metal alloy, such as Stellite, into a cast depression in a cylinder head above each eventual valve stem position,[1] and then machining a conical-section surface into the valve seat that will mate with a corresponding conical-section of the corresponding valve. Generally two conical-section surfaces, one with a wider cone angle and one with a narrower cone-angle, are machined above and below the actual mating surface, to form the mating surface to the proper width (called "narrowing" the seat), and to enable it to be properly located with respect to the (wider) mating surface of the valve, so as to provide good sealing and heat transfer, when the valve is closed, and to provide good gas-flow characteristics through the valve, when it is opened.

Increased Productivity With the Right Valve Seat Cutting Tools

You can increase your productivity in several ways when you use top-quality valve seat cutter tools from here at Colonial Tool, thanks to:

  • Faster machining speeds due to optimized tool design
  • Fewer steps with the use of dual-stage tools, or multiple cutters
  • Reduced number of passes thanks to ideal cutting angles
  • Less scrap and rework due to precision balancing
  • Quicker changeover afforded by our quick-change tools
  • Adjustable sizing for more flexibility and fewer tool changes

These advantages combine to give you a significant productivity and efficiency boost, all while improving the quality of your valve seat cutting and saving time on rework and inspection. Our flexible tools can be adjusted for a variety of valve seat sizes and diameters, so you can reduce the number of unique tools you need in your shop.

The reasons to choose our class-leading valve seat cutting tools are clear. With more and more of your competition choosing Advanced Cutting Tool Systems Valve Seating Cylinder Heads, you don’t want to fall behind due to less-capable cutting tools.

Our experienced team understands the needs of the modern machine shop, tool room or production floor. You demand quality tools that are easy to set up, provide more cutting between tooling changes/sharpening and give you the precision results your customers demand. Inadequate engine valve seat cutting can result in costly rework or scrap. Wasting time with cheaper tools that need more frequent adjustment or replacement can actually increase your tooling costs and in turn cause your cost per piece to climb.
