    Because STF Precision only manufactures cutting tools tipped with diamond, we have acquired extensive knowledge of the behavior of diamond cutting tools, especially under very specific machining conditions. Since our expertise is so focused, we have the exceptional ability to:
    Select the precise diamond to use under different machining parameters such as:
    • Orient the planes of a single crystal diamond to achieve maximum edge life
    • Provide the precise grade of diamond that will produce the surface finish you require
      • Feed
      • Speed
      • Depth of cut

  • A Family-Owned Business

    ST&F Precision Technologies & Tools, Inc. began operations in March 1992, when Ted Ford purchased Norton Company’s High Precision Diamond Product Line. As part of the purchase he acquired an extensive inventory of custom-built diamond lapping and grinding machines as well as an established customer base. Prior to the purchase, Mr. Ford had spent 20 years at Norton and was a recognized expert in diamond tooling. His expertise was evident as he successfully guided the growth of the company from 1992 to 2001.

    In June 2001, leadership of the company was passed to his son, Jason Ford, who became co-owner and President, and to his son-in-law, David Novak, who was named Vice-President. In addition, the trade name of the organization was changed to STF Precision.

    In January 2005, STF built and moved into a new, 15,000 SF production facility at 76 Old Shoals Road. Continued growth demanded another expansion in 2015, and STF began construction of an additional 40,000 SF facility. The new headquarters were opened in 2015, where STF’s 75+ craftsmen continue to produce quality diamond tooling for national and international customers.

    State of the Art Facility

    STF’s headquarters is a 50,000 square foot space that was designed and built specifically for our diamond tooling production. From the initial design we tried to take into account everything that we set us apart as a start of the art manufacturing facility.

    To maintain micron measurement consistency, and to allow for the cleanest and safest environment for our employees, the facility was designed with superior air quality in mind. Specially modified Trane (www.trane.com ) air handlers provide over 100 tons of conditioned air distributed throughout the shop by a DuctSox Textile Air Dispersion system (ductsox.com). Redundant Donaldson-Torit air scrubbers inside the facility further clean and reticulate inside air while dual 30 foot diameter overhead fans maintain constant air movement at 4 MPH.

    All interior and exterior doors are RFID and keypad controlled, and the shops lights out grinders and equipment are monitored 24 hours a day 7 days a week by a 48 camera HD surveillance system. Production schedules, Key Performance Indicators, Safety Data and other relevant information are displayed and updated in real time on 40 inch LED TV monitors throughout the facility.

  • BROAD CUSTOMER BASE
    The clients who use parts machined by STF come from a wide range of industries:

     

    • Clients Apple
    • Clients Boeing
    • Clients Bombardier
    • Clients Federalmogul
    • Clients Ford
    • Clients Gm
    • Clients Hitachi
    • Clients Honda
    • Clients Mercedes
    • Clients Nasa
    • Clients Toyota
  • Speed Is One Of Our Unique Advantages
    STF is large enough to design and tool up an entire production line, yet small enough to do it quickly. Our exceptional staff and efficient internal structure allow us to consistently turn projects around ahead of our competition.

POLYCRYSTALLINE DIAMOND TOOLS

PCD tools are common in many industries, from automotive to woodworking to printing. These tools are typically lower cost than single-crystal diamond tools and are used in production machining of many parts. Different grades of PCD are used depending on the requirements of surface finish, life, material being cut and the depth of the cut.

SINGLE CRYSTALLINE DIAMOND TOOLS

Single-crystal diamond tools are used in a number of industries when surface finish is critical to the application. Because the cutting edge is made of one large diamond stone, the tool can be ground sharp to 10,000x magnification. Tolerances for SCD tools are typically much tighter and more controlled than for polycrystalline diamond tools.

Our SCD tools are inspected by using a Nikon VMR 3020.

  • AEROSPACE

    Because of its unique properties, diamond has been increasing in popularity as the cutting tool material of choice in the aerospace industry. PCD (polycrystalline diamond) tipped drills, countersinks and routers offer several significant advantages over carbide:

    • PCD tools are cost effective. Savings can be significant because these tools can be reground multiple times and can be resharpened at a fraction of the cost of a new tool.
    • STF Precision has state of the art 6 axis grinding and erosion machines that produce drills and routers with a true uninterrupted helix from the carbide all the way through the diamond tip.
    • The technology of producing PCD tooling has evolved and resulted in competitive pricing and broader usage of these tools.
  • OPTICS

    STF Precision has developed a full line of diamond tools for the contact lens and intra-ocular lens (IOC) markets. The benefits of our products are:

    • Our insert and shank style tools are available in both natural and synthetic diamonds
    • We can control waviness to ½ micron or less, hold angles to +/- 2 minutes and generate radii from 10 microns to 4000 microns
    • Tools are inspected at 750X magnification, and pictures can be provided at our customers’ request.
  • CUSTOM HI-TECH

    STF continues to keep pace with the rapid advances in technology and supply innovative companies with the tools they need to maintain their competitive edge. These diamond tools include tolerances that split microns and sharpness that passes inspection at 10,000X magnification. STF has a history of meeting all challenges in tooling and always finding a solution for their customers’ tooling needs.
