NEW SHARP BED-TYPE HORIZONTAL MILL 
MODEL:  KMA-3H **MADE IN TAIWAN**
 
Features, Function, & Benefits:
ISO 9002 certified factory:
Quality up to world industry standards.
 
Certified MEEHANITE Casting:
Highest grade of casting possible.
Boring Capability
The full length travel of the vertical head (20” on Model KMA-1, 21.5” on KMA-2, and 30” on KMA-3) along with 6 different feeds (0.002 – 0.008 inch per revolution) offer capability for precise boring operation.
Electro-Magnetic Spindle Control
The spindle is equipped with electric power brake for instant clamping of spindle. It also has 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 utilize hardened and ground gears for long lasting wear.  The spindle head gearbox is equipped with an automatic lubrication system. The table feed gearbox has an oil splash system for lubrication.
Pendant Style Operation Panel
The pendant control panel allows easy operation of all power driven mechanism, electrical, pneumatic or hydraulic. It has a toggle style control for 4-way feed and rapid traverse of the table.
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 Boxways:
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 out of 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 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, rear reference surfaces and T slots are precision ground to exact tolerances.  
Adjustable Backlash Eliminator:
A double-nut construction eliminates backlash between the nut and the lead screw that drives the table.  This allows accurate movement of the work piece during machining.  As time goes, there will be wearing on the nut creating backlash, the double nuts can be adjusted to take out the additional backlash.  Precisely milled oil groves 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 work piece 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 coarse and fine in addition to power feed for positioning of 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 mounted at the front allowing quick positioning of the head for machining.
Oversized Spindle 
For heavy-duty cutting.
Built-In Coolant Tank
 Located at the base of machine to save space.
Pneumatic Power Locking System 
Equipped for a vertical spindle head, and a separate pneumatic system for locking table and saddle.
Variable Speed Drive On Table and Saddle
Using variable frequency inverter drive control on the motor, the feed rate of table and saddle can be varied at the turn of a knob.
Auto Lube Vertical Slideways
The slideways upon which the vertical spindle head travel, are automatically lubricated when the machine is turned on.
