A Tool and Cutter Grinder is used in machine shops to sharpen milling cutters, tool bits and other cutting tools.

A Tool and Cutter Grinder is used primarily for metalworking and features an abrasive grinding wheel on a universal head with vise, headstock, tailstock and multiple attachments for holding the workpiece.

A Universal Tool and Cutter Grinder has a universal workhead that rotates and adjusts to any rake or angle at either horizontal or vertical positions.

More Than Sharpening

Though mainly used for sharpening, cutter grinders, as the name implies, are also used for grinding.

Tool Cutter Grinding Applications

 

A LeBlond Tool and Cutter Grinder has numerous grinding applications

 A Universal Tool Grinder has unique features and functions that allow:

  • Surface Grinding where a machinist can create a smooth surface on a flat surface with the grinding wheel
  • Tool Grinding for sharpening
  • Broach Grinding to remove material from a workpiece for axisymmetric shaping on the grinding wheel
  • Internal Grinding of the internal diameter or ID of a workpiece
  • Helical Grinding to produce precision spurs or helical gears on the grinding wheel
  • Internal & Outer Cylindrical Grinding where the workpiece is mounted on centers for grinding
  • Wheel Dressing Grinding where a tool is used to dress or slightly trim the surface of the grinding wheel to “true it up”
  • Step Grinding or a similar process to shimming

 

Universal Tool and Cutter Components

 

The Working Table of the grinder is the surface where the workhead rotates 360° in order to grind a variety of cutting tools. For the most effective grinding, the working table itself can rotate 120° by 60° with the graduated scale attached.

 With the Clutch, the speed of the working table’s feed is controlled. Speeds can be either high or low with a feed knob on both sides of the working table of the K.O. Lee Universal 40M or 60M Cutter Grinder. With these tool and cutter grinders, the handle on the right-hand side of the cutch controls lower speeds to prevent interruptions.

All Angles Wheelhead & Grinding Wheel

 

The Wheelhead and grinding wheel can grind any angle requested by the operator. The inclination of the Wheelhead tilts easily up to 15° and has a 360° swivel on the horizontal plane.

 The Angular Contact Ball is an essential component, designed in pairs to support the spindle and bearing. There are two pairs, tightened by nuts, and held in place for support.

Tool Grinder: Less Maintenance & Greater Efficiency

 

No additional lubricant is needed on the grinding wheel swivel’s interior as it is already well greased.

 Another component is the precise Ball Groove of Conformation constructed of special alloy steel. This roll of steel cable drives the working table, improving the operator’s efficiency. 

K.O. Lee Universal Tool and Cutter Grinder Custom Features

 

A K.O. Lee tool cutter grinder has custom features to allow you to tackle any job requirement

Our Universal Cutter and Tool Grinders are custom machines with a variety of features, including:

  •  A hydraulic cylinder that drives the x-axis in transverse motion.
  • A servo motor driving the y-axis in cross motion.
  • A PLC touch screen panel enabling manual inputs.

 The Centralized Lubrication System of K.O. Lee Universal Cutter Grinder machines allow lubricant to be supplied evenly to the grinding wheel and every part of the machine, keeping them in superior condition and extending machine life.

 There are also the two Tailstocks, which partner cohesively with the Workhead to hold the Workpiece steadily and achieve superior results. One Tailstock is fixed by a bolt while the other is fixed by spring pressure.

The above features are not standard but add-ons to our manual tool cutter grinder. 

Cutter Grinding

 

There are many tool cutter grinder attachments which enable the machinist to better customize his or her work on the grinding wheel. The attachments used by the machinist will depend on their needs and what they are creating.

A. Face Mill Grinding makes it simple to set elevation and depression angles, as well as to grind large size cutters and tools. With a horizontal swiveling base, this attachment allows a workspace of up to a 15° angle.

B. Radius Grinding Sharpening enables sharpening of the radii of ball end mills and styli. With an index plate mounted on the back of the workhead, the Radius Grinding allows for the indexing of straight flutes cutters. There are two slide bases with micrometer adjustment and workhead.

 C. Radius Grinding Corner is used to grind an accurate radius on the corner teeth of face mill and shell end mills. Upon grinding, set the position by micrometers to prevent error.

 D. Lathe and Planer Tool Grinding allows for the grinding of lathes and planer cutters, creating a large work support area. Set the cutters for grinding rake and relief angles.

 E. Helical Grinding is an attachment used to grind relief and rake angles of spiral cutters or straight teeth of end mills, hobs and center drills.

 F. With Workhead Indexing, a machinist can reduce the need for tooth rest when grinding cutters. The indexing is simple and efficient when mounted to a standard workhead. The attachment comes with a plate that has 24 equal slots.

 J. Internal Grinding is used with another attachment, the Motorized Workhead. It is the best solution to grind internal capers.

 K. When setting out to perform small cutter grinding jobs, the Collet Chuck is the ideal attachment. Mounted right into the workhead’s taper hole, this Chuck works seamlessly when grinding.

 L. The Motorized Workhead is used for the face grinding of numerous tools as well as straight or taper cylindrical grinding.

 M. Wet Grinding utilizes a Coolant Supply System for grinding operations that need coolant such as surface, internal and cylindrical grinding.

The Name Says It All

 

The purpose of tool and cutter grinders is to sharpen a broad swath of tool bits and cutting implements and grind as well with a panoply of attachments and custom features.
