Mechanical Design Robust and Precision Machine Bed The major construction parts are based on Meehanite cast iron, which is structurally stable, ensuring permanent machine quality. The computerized calculation of structural strength and reinforcing ribs is carried out by way of finite element analysis, ensuring high rigidity of the machine. 4
Mechanical Rigidity Unique Rib Construction Wide base and robust structure ensure steady machining against heavy loads. 5
3 Axis Transmission System 3 Axis Ballscrew System The 3-Axis ballscrew employs large diameter ballscrews to enhance transmission rigidity, ensuring repeatability and precise positioning. X / Y / Z rapid speed: 36 m/min (LH-5) 32 m/min (LH-63/8) Synchronized telescope covers are provided for all 3 axis, eliminating transmission noise and vibration. High Speed, High Precision Linear Guideways Roller linear guideways with zero backlash ensure consistent cutting surface on curve or slope cutting. Suitable for high speed travel, the drive power requirement is significantly reduced. Roller Linear Guideway By using rolling contact instead of sliding contact, linear guide reduces friction loss, reacts quickly, and increases positioning accuracy. The loading capacity is high in multiple directions. Multiple contact points are maintained when machining, and cutting rigidity can be ensured. Easy to assemble and interchangeable, with a simple structure for easy lubrication. Long service life is guaranteed by the extremely low friction loss in the linear guideway. 6

The coolant oil automatically circulates through the ballscrew, eliminating heat generation and thermal expansion during high speed rotation, so as to accomplish high-speed and high precision machining. 7
Tool Change System (ATC) & Magazine Fast, simple, reliable and long service life tool change system provides stable and reliable tool change operation. The unique tool change systems adopts an advanced cam drive device. Tool selection can be done quickly using the PLC program from any tool position. The ATC system passed 1,, endurance tests to meet reliability requirements. The cam drive device of the magazine ensures precision rotation, ensuring smooth operation of the magazine even in heavy tool operation. KMH-5 KMH-5 KMH-63 8
High Speed Mechanism Shortens Non-Machining Time Substantially The capability to shorten the time for spindle acceleration, deceleration, transmission and tool change is the key to high cutting efficiency. The KMH series shortens the overall process time by increasing the speed of key mechanisms. 9
Wash Down System Coolant Tank and Disc-Type Oil Separation Disc-type oil separator is easy to install and saves space. It enables effective separation of floating oil in the coolant tank, ensuring quality and prolonged service life of the coolant, improving the quality of the process. Internal Coolant / Wash Down Device Coolant is sprayed from nozzles above the hood, preventing accumulation of chips. Coolant Spray Gun Spray gun for easy and prompt cleaning of the machine. Removes and cleans remaining chips that stick to the machine, maintaining it in a clean and tidy condition. 1
High Performance Equipment Coolant through Spindle (CTS) Unit CTS is optional. CTS allows high pressure coolant to travel through the spindle and tool, to immediately take away the heat. Linear Scales X/Y/Z Axis can be equipped with linear scales. Air purge is equipped to protect the linear scales, to avoid dust or oil mist contamination. This helps the precision and lifespan of the linear scales. Track Type Chip Conveyor and Chip Storage Cart Chip augers are provided on both sides of worktable, with track type chip conveyor and chip storage cart installed in front of machine. Large amounts of metal chips can be handled via this chip removal mechanism. 11
