Johnford’s VMC Series is a combination of speed, rigidity and precision in a box way geared head package. These C frame machines feature solid heavily ribbed Meehanite cast iron eliminating vibration and ensuring excellent surface finishes and long cutting tool life.

 

Four oversized box ways fully support the machine’s saddle and work table delivering outstanding X axis accuracy over the full travel range of the machine. This is critical when machining heavy workpieces to avoid deflection and is a key factor in maintaining part accuracy and precision. All sliding surface areas and gibs are coated with Turcite-B and hand scraped for perfect fit and alignment.

 

Optimum alignment of the motor and gear box ensures no offset and guarantees steady smooth movement of the head stock along the Z axis. This design significantly reduces torsion on the head stock and ensures optimum rigidity, long term accuracy and repeatability. Large diameter pre-tensioned ballscrews have a double-nut preloaded design eliminating the potential thermal growth and promote high accuracy and high speed positioning.
