VTP Series Vertical Machining Center
Model：VTP Series
VTP series is a one-piece fabricated with box ways design. The manufacturing of a machine with box ways construction require high manufacturing technology as well as experience. At Chi-Fa, we have an integrated manufacturing capability in combination with over 30 years in machine tools manufacturing experience. Unlike competitors procurement of parts from outside suppliers, Chi-Fa machines are designed, manufactured and quality controlled in-house for rigorous control throughout the entire manufacturing process.

Description
ㆍBox ways on X, Y, Z-axis provide ultra-high rigidity that effectively overcome backlash error and vibration problems. 610 mm of Y-axis travel meets most of molds and parts machining requirements, making the machines excellent for high precision mold machining.
ㆍDirect drive of Z-axis motor in combination with the use of extra long sliding blocks allow feeds to be more accurate and sensitive especially in heavy cutting. The contracted simplified headstock dramatically reduces the distance between the headstock and the column, that eliminates deformation caused by a force or defection due to a gravity, increases rigidity to meet the requirement for high precision machining.
ㆍThree axes are transmitted through 40 x P10 mm, class C3 ball screws, pretensioned to enhance the axial rigidity and reduce thermal elongation to a minimum. Four box ways an base are one-piece fabricated. Y-axis slide ways design is based on the optimal supporting distance.
ㆍFour box ways design combined with greater span provide a solid support in the machining range of X-axis. Manufactured from high quality Meehanite cast iron, the base features high rigidity and high dampening capacity to increase cutting stability.
