Overview

Bed type vertical mills are ideal for milling large work piece or heavy cutting on hard metals. The quill is fixed so it can withstand strong lateral forces. For this model, the entire vertical head moves up to 20” that enables deep drilling and boring operations. The large spindle with #50 taper can remove large amount of metals in one pass. Even though the geared vertical head is huge, it travels smoothly by cranking the  eye level tri-lever handle.

Features

Solid Construction, Box Way Design

High quality castings are used on base, column, saddle and table. They are stressed relieved to avoid any distortion. All sliding surfaces are hand scraped to ensure full bearing support. All reference surfaces and T slots are precision ground to exact tolerances

Honeycombed Ribbing on Column

The vertical column of a bed mill usually received most pressure during heavy duty milling operations. Honeycombed pattern ribbings enhance rigidity of the casting.

Double Nut Backlash Eliminator

Backlash on the screw increases after long term usages. The backlash eliminator can correct the situation by adjusting the double nuts instead of the old method of squeezing a split nut.

Extensive operating panel

Operating panel includes toggle control of table and saddle feed, joystick control head up down. Digital display of spindle speed and vertical head feed rate. Push button for vertical head rapids Dials for variable speed of table and saddle feed.

Eye-Level Tri-Lever Handle Vertical Head Movement

Despite the heavy duty vertical spindle head, it is easy to move the head up and down manually using the tri-lever handle for positioning or close milling jobs.

Well Organized Electric Panel

All relays, contactors, transformers, overload protections, safety disconnect switches and wires are clearly labelled for easy maintenance.
