Boring Capability

The vertical head’s full-length travel (20” on Model KMA-1, 21.5” on KMA-2, and 30” on KMA-3) and 6 different feeds (0.002 – 0.008 inch per revolution) allow for precise boring operation.

Electro-Magnetic Spindle Control

The spindle is equipped with an electric power brake for instant clamping of the spindle. It also has a forward/reverse switch for tapping operation, and spindle jog motion for proper tool holder engagement.

Hardened and Ground Gears

The gearbox inside the spindle head and the table feed mechanism utilizes hardened and ground gears for long-lasting wear. The spindle head gearbox is equipped with an automatic lubrication system, and the table feed gearbox has an oil splash system for lubrication.

Auto Lube Table and Saddle Ways

The slideways upon which the saddle and table travel are automatically lubricated when the machine is turned on.

Hardened and Ground Box ways:

The C-frame construction offers the best machining capability for heavy milling and boring applications. By using hardened and ground double box ways in the Z axis, significant rigidity is given to the cutting head. The saddle is also mounted on two massive hardened and ground body ways for maximum stability during heavy cutting.

Honey Combed Ribbing:

The vertical column is made from box-shaped, high-quality, gray iron castings. It is reinforced with honeycombed ribbing, instead of the usual rectangular ribbing, which is 70% more effective in dampening vibration and sustaining mechanical and thermal stability.

Table and Saddle:

High-quality castings used on the table and saddle are stressed and relieved to avoid any slight distortion in the future, and the sliding surfaces are hand scraped to ensure full bearing support and to achieve high accuracy in machining. All top, front, and rear reference surfaces and T slots are precision ground to exact tolerances.

Adjustable Backlash Eliminator:

A double-nut construction eliminates the backlash between the nut and the lead screw that drives the table. This allows accurate movement of the workpiece during machining. As time goes on, there will be wear on the nut, creating a backlash; the double nuts can be adjusted to take out the additional backlash. Precisely milled oil grooves on top of the saddle ensured adequate lubrication between the table and the saddle.

Unique Sliding Saddle Base Design:

To allow easy access to the workpiece for inspection or positioning, the entire saddle base can slide in and out from the operator manually or by power feed. This feature is particularly convenient considering the cross movement of the saddle can reach up to 23”.

Eye Level vertical Head Control:

The large spindle head offers manual course and fine in addition to a power feed for positioning the head. Controls for these feeds, together with spindle speeds and the head locking mechanism, are all mounted at eye level on the spindle head casting. The tri-lever rotating manual rapid feeds are mounted at the front to allow quick positioning of the head for machining.
