Drilling and Milling Machine ZX 7055 VARIO DRO – professional drilling and milling machine for precision metalworking

Drilling and Milling Machine ZX 7055 VARIO DRO by CORMAK is an efficient universal milling machine for drilling, milling and tapping in steel and cast iron. The design based on a massive casting, continuously variable speeds in two ranges and a digital position readout ensure repeatable accuracy in one-off and small-batch work.

Main advantages of the machine

• Rigid cast iron base and column – stability when machining demanding workpieces, reduced vibration and extended tool life.
• Continuously variable spindle speed in 2 ranges: 75–438rpm (low) and 438–2500rpm (high) – optimum selection of parameters for tool diameter and material.
• 2-axis digital readout (DRO) – fast positioning without vernier reading errors, shorter setup time.
• Automatic spindle feed – even cutting and lower risk of drill breakage during deep drilling.
• Tapping function - after reaching the set thread depth, the spindle switches to reverse motion
• Ground gears – quiet gearbox operation and stable torque on the spindle.
• Dovetail guides on the axes – precise table movement and reliable geometry.
• Swivelling head ±90° and height adjustment – easy chamfering, undercutting and angular operations.
• Left/right rotation – safe tapping and tool withdrawal.
• Efficient cooling system, which effectively dissipates heat during machining, prevents overheating of the tool and material, and thus increases working precision and the durability of cutting tools.

Construction and technology

The core of the machine is a heavy cast iron casting with wide guides, which minimises deflection during face milling and end milling. The massive cross table with a large working area has a precision-ground surface, which guarantees flatness for setting. The spindle with an MT4 taper is driven by an S1/S6 1.5/1.8kW motor with continuously variable speed control. The integrated cooling system stabilises the temperature of the cutting zone and improves surface quality.

Precision and working efficiency

The combination of a 2-axis DRO, ground gears and solid guides ensures high dimensional repeatability and surface smoothness. Automatic spindle feed and two speed ranges make it possible to select stable parameters for drilling in steel up to Ø32mm and cast iron up to Ø45mm, as well as face milling up to Ø80mm and end milling up to Ø28mm. Ergonomic head height adjustment shortens changeover time for both batch and one-off workpieces.

Application

ZX 7055 VARIO DRO is recommended for tool rooms, maintenance departments, metalworking shops and small-batch production, where a multi-purpose drilling and milling machine combining drilling, milling, countersinking and tapping on one machine is required.
