Economical and easy to operate. Our manual and automatic industrial K.O. Lee surface grinders offer all of the accuracy of
more expensive surface grinders, with the same quality features.

The KOL-618 High Precision Surface Grinder has longitudinal and cross slide ways that are precision handground and then laminated with Turcite-B. This provides a smooth, even travel with low wear. A full support system maintains accuracy during table reversing and full length of travel. Main components include base, column and saddle. They are made of High Quality Meehanite cast iron stress relieved to insure rigid stability.

The features also include slip-ring hand wheel dials, a removable cartridge-type spindle with a pair of duplex
Class 9 bearings and dynamically balanced V-3 motor starting at 1.5 HP. Increased HP packages available.

Y-Axis Micro Feed

A feature that allows for extremely precise movements in the Y-axis direction to create precise dimensions and tolerances in the final workpiece.

Z-Axis Micro Feed

A feature that allows for exact movements in the Z -axis direction, enabling operators to make precise adjustments to the position of the cutting tool.

Permanent Magnetic Chuck

A magnetic workholding device that doesn’t rely on electricity and ensures that the workpiece remains firmly in place and does not move or shift during machining.

Coolant System

Used to cool and lubricate grinding tools and workpieces during machining operations, helping to reduce heat and prolong the life of these tools.

Dust Collector

A system that removes dust and other particles from the air that are generated during the manufacturing process.

Coolant System and Dust Collector

The combined system can provide better air quality in the workplace by removing both dust and coolant mist from the air.

Auto Paper Strip Filter with Coolant

A type of filtration system that removes contaminants from coolant fluids used to cool and lubricate grinding tools and workpiece during machining. It filters out any chips or particles that may still be in the coolant before it repasses through the machine.

NC Automatic Down Feed

A 2-axis motor-driven machine with a hydraulic table that turns into a fully automated machine to prolong the life of the grinding tool, reduce cycle times and improve the quality of the machined surface.

Manual Parallel Dresser

Allows the operator to have greater control over the dressing process for greater precision by manually positioning the dresser relative to the grinding wheel and making the necessary adjustments to ensure that the wheel is dressed parallel to the workpiece.

Spare Wheel Flange

A critical component that connects and secures the grinding wheel to the machine, ensuring greater safety, reduced operational vibrations and optimized grinding performance.

Semi-Enclosed Splash Shield

A coolant and safety feature mounted onto the machine table with doors that have an operator safety interlock.

Back Water Splash Guard

A component that acts as a splash guard and mounts to the back of the machine table to prevent water and coolant from splashing up onto the machine rear during operation.
