Inclination of Wheelhead The wheelhead can easily tilt up to ±15°, with a 360° swivel on the horizontal plane. The wheelhead can grind at any angle the operator desires. Two pairs of angular contact bearings are designed to support the spindle bearing and are tightened by nuts. The wheel spindle mechanism is greased with lubricant and does not need any additional lubricant.

Universal Workhead The workhead can rotate and adjust accurately at any angle, either horizontally or vertically. The spindle is tapered at both ends, NT#50 (BT#50) and MT#5. This may increase work-efficiency with various .

Work table The work table can rotate 120°, with a ±60-degrees graduated scale attached. At the same time, the workhead can rotate 360° to grind various cutting tools.

2 www.kentusa.com Precision bearing groove slideways The machine provides a precision bearing groove, which is made of a special alloy steel. The work table is driven by a roll type of steel cable. This improves the work efficiency for operators.

Clutch The feed of the work table can be controlled at various speeds, both low and high. The work table of the M-40 grinder has a feed knob on both sides, while the clutch handle on the right hand side controls the machine at a lower speed for smooth, precision grinding.

Tailstock There are two tailstocks: one is fixed by a bolt, and the other is fixed by spring pressure. The tailstock and workhead steadily and firmly holds the workpiece, achieving the best outcome.

Centralized lubrication The M-40 machine has a centralized lubrication system that provides an ample supply of lubricant to every part, evenly. This ensures that the machine will perform in top- running condition, while extending its life.
