KT-20M

One piece casting slant bed design provides better structure rigidity. With the 30˚ slant bed design and heavy-duty structure foundation, an optimization of the rigidity of the overall machine structure is applied to the headstock, turret, and tailstock.

 

 

KFM insists to use MIT (Made In Taiwan) casting only to offer our users the best quality assurance. Lasting metal cutting precision accuracy and cutting tool life extension are guaranteed. TURCITE-B is applied and firmly adhered to both X and Z slideways, to prevent the counter-flow of lubricator and provide smooth transmission. A sustaining production accuracy request is fulfilled.

Hand-Scraped Technique

 

Hand-scraped procedure is applied to contacting surfaces through all the guide way slides, headstock, turret and tailstock. The ultimate assembling precision, structural rigidity, and balanced loading distribution are secured.

 

Ball Screw

 

All products are equipped with C3 class ball screws to ensure high positioning accuracy. The ball screw pretension design is applied to all axes to effectively minimize the backlash compensation of the machine body needed. The repeatability and positioning accuracy is highly secured.

 

Spindle

 

The headstocks for all the products are equipped with one-piece casting. High precision Japan-made bearings from NSK are installed to provide high capacity of the bearing load, and effectively deliver a high precision and durability performance.

 

Turret

 

The interior mechanism employs flat parallel cam, featuring high indexing accuracy and fast tool changing time. Turret disk rotation is driven by oil pressure motor to provide strong cutting torque and enhance the performance stability. It suits both heavy and light cutting.

Spindle

 

The headstocks for all the products are equipped with one-piece casting. High precision Japan-made bearings from NSK are installed to provide high capacity of the bearing load, and effectively deliver a high precision and durability performance.

Bar Feeder

 

Optional automatic bar feeder choice will provide better productivity performance by minimize the time needed for feeding the materials. No restriction on the spindle speed or the shape of material. Alternative feeding torques can be applied for different diameters of material, weight and length to avoid the deformation of materials.

 

 

Tool Presetter

 

Optional Reinshaw or Marposs tool presetter accessory provides higher production output and minimizes the machine idle time. It precisely measures the cutting tool length and diameter, and offers solution for tool setting, broken tool detection, component set-up, in-cycle gauging and first of component inspection, with automatic offset updates.

 

 

Parts Catcher

 

Parts catcher automatically receives the finished parts. To provide easy access to the finished parts without going through the trouble of opening the machine door. High efficiency and operator friendly

 

 

Gantry Loading / Unloading System

 

Automatic parts loading and unloading system provides one more solution to the high labor mobility issue with the side benefit of offering high production output. The system is available to one-to-one or one-to-many machines. This is a future tend that you wont want to miss!
