Radius Grinding Fixture

 

Description:

Radius Grinding Attachments are for grinding ball, corner radii and concave radii on end mills and other shank-type cutters, as well as for grinding radii on arbor-type cutters.

Unit 6B Ball bearing work head for shank-type cutters

Unit 6A Ball bearing work head for arbor-type cutters.

The Unit 6 is a precision tilting compound slide for setting end mills and cutters to correct position when grinding radii on cutters and end mills. It is especially designed for the Work Head No. 6-A and the Work Head No. 6-B. The Unit 6 is built to close standards of accuracy and workmanship and will produce a fine finish with a close tolerance over a long period of years.

All sliding surfaces such as saddle ways and table ways are hand scraped for accuracy and sensitive movement.

The Unit 6 may be used on most makes of tool grinders. The work table is accurately ground all over for ease of set-up. The base has a graduated scale of 30 degrees, 15 degrees from each side of 0, so the table can be tilted two ways. The two feed screws have dials graduated to one thousandths of an inch. Dovetail ways have adjustable gibs to take up for wear on cross slide and work table. The entire holding unit is mounted on ball bearings and the swivel base is graduated 360 degrees.Radius Grinding Attachments are for grinding ball, corner radii and concave radii on end mills and other shank-type cutters, as well as for grinding radii on arbor-type cutters.Unit 6B   Ball bearing work head for shank-type cuttersUnit 6A   Ball bearing work head for arbor-type cutters.The Unit 6 is a precision tilting compound slide for setting end mills and cutters to correct position when grinding radii on cutters and end mills.  It is especially designed for the Work Head No. 6-A and the Work Head No. 6-B.  The Unit 6 is built to close standards of accuracy and workmanship and will produce a fine finish with a close tolerance over a long period of years.All sliding surfaces such as saddle ways and table ways are hand scraped for accuracy and sensitive movement.The Unit 6 may be used on most makes of tool grinders.  The work table is accurately ground all over for ease of set-up.  The base has a graduated scale of 30 degrees, 15 degrees from each side of 0, so the table can be tilted two ways.  The two feed screws have dials graduated to one thousandths of an inch.  Dovetail ways have adjustable gibs to take up for wear on cross slide and work table.  The entire holding unit is mounted on ball bearings and the swivel base is graduated 360 degrees.

 

Features:

Easy to operate
Extremely versatile
Sturdy construction
Adaptable to most makes of tool and cutter grinders
One side of the Unit 6 base is accurately machined to facilitate set-up.
The Unit 6 and workheads 6A and 6B may be used independently for other non-radius tool grinding functions.
The Unit 6 may be used as a wheel dresser to dress one or two angles tangent to radius.
Two ball bearing work heads, No. 6-A and No. 6-B, are available.
The Unit 6 with Work Head No. 6-A will do five operations on side milling cutters without removing cutter from work head spindle.
Sharpens peripheral teeth (1); sharpens side teeth on both sides (2 & 3); and sharpens small or large radii on both corners of each tooth (4 & 5).
All work heads have right angle keyways in the base so they can be used two ways on the Unit 6 table or the grinder table.
The Unit 6 and Work Head No. 6-A and 6-B may be used on tilting or stationary head tool grinders.

The cutter spindle of Work Head No. 6-A is mounted with precision pre-loaded ball bearings and is dust proof for sensitive movement of the spindle. The spindle assembly on Work Head No. 6-A is interchangeable for different size spindles if needed.

The Unit 6 and Work Head No. 6-A will sharpen radii on plain milling cutters, side milling cutters, shell end mills, metal slitting saws, single or double angular cutters, half side helical milling cutters, and many other special forms.

Work Head No. 6-B with standard equipment is especially designed to fit the Unit 6. The spindle is heat treated and ground to close tolerance and has a 5-C collet bore. Accurately mounted on pre-loaded ball bearings, sealed and lifetime lubricated, it needs no attention. The index lock bracket is easily removed when the universal tooth rest is mounted on the Work Head. Standard index has 24 divisions. Other discs to 48 divisions are available as optional equipment. Work Head No. 6-B is Meehanite casting construction. Its spindle is so accurately mounted that it rotates at a finger’s touch.
