20″ x 87″ New Sharp Bed Type Mill Model KMA-3H Features, Functions & Benefits:

• ISO 9002 certified factory:
  Quality up to world industry standards.

• Certified MEEHANITE Casting:
  Highest grade of casting possible.

• 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.

• Pendant Style Operation Panel
  The pendant control panel allows easy operation of all power-driven mechanisms, 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 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.

• Oversized Spindle
  For heavy-duty cutting.

• Built-In Coolant Tank
  Located at the base of the machine to save space.

• Pneumatic Power Locking System
  Equipped with a vertical spindle head and a separate pneumatic system for locking the 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 travels are automatically lubricated when the machine is turned on.

• 7.5 HP horizontal spindle

• Ball screw and AC servo motor drive on horizontal head

• Electronic handwheel (MPG) on horizontal head travel
