OKK History

OKK Corporation has been in business since 1915, though under different names over the years. In 1998, they received their first significant order for horizontal machining centers in the United States, (which were purchased for use in the automotive industry).  You can find CNC’s from OKK manufactured as far back as 1988. They have offices around the word including in Canada, Mexico, Korea, Indonesia, China and in Thailand. It is a publicly traded company on the Tokyo Stock Exchange. As of 2018, OKK Corporation is reported to have 759 employees around the world and nine subsidiaries. In the United States, the OKK USA Corporation head office is located in Glendale Height, IL (near Chicago) and a regional office is located in Irvine, California. Machine tools are OKK Corporation’s core business, and they are focused on creating heavy-duty cutting tools with high rigidity for higher efficiency and increased machine accuracy.

OKK Vertical Machining Center Series Information

The OKK vertical machining center series is divided into 5 main classes:

  • VM R Series: Designed for ultra-heavy-duty cutting with large box ways, high torque and high horsepower spindles for hard-to-machine materials like Inconel’s, titanium or mold work.
  • VP Series: Designed for speed with a bridge style structure for increased rigidity combined with the largest cross linear roller guides in class, 40 taper spindles and option for direct-drive pallet changers.
  • VB Series: One size designed for mold work at a competitive price.
  • KCV Series: Designed for long aerospace and oilfield parts, but the 5-axis models are also common for automotive industry manufacturing of some truck/semi-axle parts.
  • VC Series: Designed to be economical, compact and high performing machining centers

OKK Horizontal Machining Center Series Information

The OKK horizontal machining center comes under three main series types as of 2018, the MCH R Series, HMC Series, and HM Series. The MCH R Series is designed for ultra-heavy-duty cutting with large box ways and high torque spindles which work well for exotic materials. If you need an OKK horizontal machining center that can handle hard to process materials like Inconel, titanium, and Hastelloy, this could be a good series of machines for you to consider. You’ll find the model numbers all start with MCH and end with R in this series. This series has been in production for a while, though not with the “R” until recently. The newest models are designed to produce up to 1,348 ft/lbs of spindle torque.

The OKK horizontal machining center series with the most options is the HM Series. It comes in a large range of sizes and with 50 taper and large cross roller guides. The HM1600, for example, has 94” x 64” x 68” (X,Y,Z-Axis) travels, 50 spindle taper, FANUC 31-iA5 controls and a cutting feed rate of about 788 ipm.

The OKK horizontal machining center HMC series is the fastest series reaching 1G in acceleration with the largest cross linear roller guides in class and 40 taper spindles. They are constructed with lightweight columns featuring a rigid stepped X-axis rail design and have a rapid feed rate of 2480 inches per minute on the 2018 models.

Found a Used OKK For Sale that Looks Interesting? Here’s what you can do before you go see it.

  1. Be informed. If you find an OKK VM7 for sale for example, you’re going to need to do more research than when buying a new CNC. Start by making a list of your requirements. You should consider the:
    • Types of materials you want to machine – Are the easy or hard to machine?
    • Tolerances you need – Tight tolerances or not?
    • Industries you’ll primarily be serving – How complex are the parts for this industry?
    • Level of production you’ll be running – High volume light-out? Or short runs?
    • Expertise you have available in your shop – Does anyone know the controls or have time to learn?

You may want to buy a similar CNC to an OKK that you already have, or you may want to look for one that is newer, so you can begin to connect everything via ethernet or Wi-Fi to take advantage of software innovations.

  2. Ask if it comes with its OKK CNC manual.
  3. Find your local distributor of OKK CNC machines and find out if they’ve provided service to this machine before.
  4. Search similar years for the OKK CNC to see how pricing compares.
  5. Get the hours of operation.
