OKUMA® Compatible Modular Subplates

Description

Okuma compatible modular subplates

Tosa Tool builds OEM-fit modular fixture plates for Okuma CNC mills and machining centers. These plates are designed around your machine’s table so you can mount once and change setups with modular workholding — without re-tramming a vise every job.

Machine series & models in the configurator

Use the dropdowns above to select series → model → material. Current Okuma options include:

• M Series: M460, M560, M660
• MB Series: MB46V, MB56V, MB66V, MB80V
• MF Series: MF46V
• MA Series: MA550V, MA650V

If your Okuma mill isn’t listed, we can still help — use the Custom Plate Builder or email your table size and model to dan@tosatool.com.

Add Options & built-to-fit accessories

Select your plate, then Add Options to your Modular Subplate and add built-to-fit hardware accessories. Available add-ons include:

• Keyway locating bores & pins
• Set screws and plugs
• Plate mounting kit (t-nuts and capscrews)
• TT 6″ modular vise
• 8″ modular angle plate
• 20-pc modular pin kit
• Tosa Tool modular full kit or half kit (with shipping)

That way the plate and the accessories that fit it travel together in one order.

Tosa Tool hole pattern (TT)

The TT standard hole pattern is two nestled 1.2500″ grids sharing the same plate:

• Precision bore grid: ø.5010″ ±.0002 TYP on 1.2500″ centers — for locating pins and accurate repeat setups
• Threaded hole grid: 1/2-13 UNC 2B thru TYP on 1.2500″ centers, with ø.5625 × .19 counterbore (~3/16″ deep) — for clamps, bolts, and modular accessories

The two patterns are offset so bores and threaded holes alternate; neighboring holes (bore next to thread) fall on 0.625″ centers. Same pattern across Tosa Tool modular subplates so options and built-to-fit hardware accessories line up from plate to plate.

Material options

• PH — 4140 PreHard steel: excellent strength and durability for production workholding
• MC — medium-carbon steel: strong, long-life steel plate
• AL — 7075-T6 aluminum: light but strong; popular when weight and handling matter
