Z3150 / Z3350 Radial Drilling Machine

The Z3150 / Z3350’s lifting distance of arm / sleeve runs 580 / 580 / 735 / 800 / 1000 / 1250 / 1250 mm. The whole point of the machine is that the spindle comes to the hole, so measure your widest workpiece with margin and check it against that figure — chasing holes by re-clamping a heavy weldment defeats the machine.

The Z3150 / Z3350 runs stated per model r/min on a 5# / 5# / 5# (II type) / 5# / 6# / 6# / Metric 80 spindle taper. Big holes in tough material live at the bottom of the range where torque works; small holes want the top. A machine that covers both ends handles the whole job list instead of half of it.

Two build points matter most on this machine: the arm guideway is inlaid with steel, a construction worked out from the quality-feedback and maintenance records of close to ten thousand radial drilling machines and around thirty years of building steel guideways; and the inlaid rail takes the wear that would otherwise fall on the arm guideway, so spindle drilling accuracy and spindle-box clamping hold up after years of arm travel. Structure decides how a machine ages — the specification table tells you what it does new, the build tells you what it does in year five.

Both sit in the radial drilling machine group, so the decision is capacity and duty, not kind: put your largest part dimensions, material and yearly quantity against each specification table and one of the two will run out of a figure first. Send the drawing and we will name which of the two fits — including the case where the smaller machine does the job.

Standard configurations generally ship within 30 to 60 days of a confirmed order, with the date written into the contract. The Z3150 / Z3350 then carries a 12-month warranty on main components, handled by the plant that built it, with lifetime technical support and spare parts identified by part number at handover.
