Subplate Features, Styles, and Options

Stevens Engineering, Inc offers numerous styles of subplates with optional features that will meet your shop's needs. Whether you run small VMCs, large HMCs, or VTLs, we have the product to increase your job change-over accuracy and reduce your spindle down time.

Features
  • Stevens Subplates set the industry standard for accuracy and versatility.  Save 15 minutes to 2 hours on every fixture setup.  Subplates pay for themselves in 20-50 setups.
  • Jig-bored bushed holes and threaded holes form the basic Stevens pattern for mounting modular accessories.
  • Subplate is permanently aligned to machine axes and becomes an accurate reference for machine setups.  Accuracy of grid eliminates the need for indicating or probing.
  • Stevens Subplates are precision ground to a parallelism of .0005 " per 40".  Accuracy of grid is detailed HERE.
  • Counterbored clearance holes to fit the T-slot or threaded hole pattern on any make and model of milling machine are included.
  • Over 300 shapes and sizes of subplates are available to fit virtually any make or model of milling machine.  Specify the make and model of machine when ordering subplates.    
Styles
  • Select Standard Duty or Heavy Duty:
Standard Duty
Heavy Duty
1/2 -13 threads on 1.25" centers 3/4 -10 threads on 2" centers
1/2" bushings on 5" centers 3/4" bushings on 8" centers
1.4" subplate thickness 1.65" subplate thickness
Vertical Spindle Mills Horizontal Spindle Mills
Subplate alignment to the machine axes is generally done with an indicator in the machine spindle by referencing two Subplate bushings.  Additional locating features for positioning Subplates are available if desired. Subplate locating features to match machine pallet locators are recommended to simplify positioning and alignment of Subplates on horizontal mills.

 

EDM Machines
Stevens Subplates and accessories are ideal for ram-type EDM machines.  Stevens Chip plugs are recommended to keep debris out of threaded holes and bushed holes in Subplates.
Starter Subplate P/N 175110-1
Ideal for knee mills with small workpieces. May be easily moved from one machine to another. Starter Subplates may be exchanged at any time for a larger Subplate which is matched to your  machine table. 

Project Subplates

Used to build setups using modular setup components in an area separate from the machining operation. They may then be quickly and accurately mounted onto primary table tooling at any time.

Project Subplates are available in various sizes including Silo Subplates and Project Subplates for 2-sided Angle Plates.

Options
Coolant Return Trough is recommended on knee type mills using flood coolant. Trough allows for return of coolant to the sump. Chip filter screens are included.

‘C’ Series Pattern is a lower cost alternative to the basic pattern because of fewer threaded holes. This pattern is used for quick mounting of dedicated fixtures, project plates, and some accessories. It is not suitable for building fixtures with setup components.

Riser Subplates are used on machines used mainly for flat, low-profile work that needs to be raised closer to the spindle nose. Riser section may be integral with Subplate or may be removable if Subplate is also to be used in its standard thickness.

Alphanumeric Address Marking is available as an option on all Stevens Subplates. Deep-etched letters and numbers facilitate documenting location of locators and clamps for future duplication of setups.

Matched Grinding - Multiple Subplates used on machines with pallet  changers should be ordered match ground unless machine control is capable of storing pallet offsets independently.
