Who uses the UWF 90-1270 with pneumatic clamping and for what
The Bernardo UWF 90-1270 in its complete configuration with DRO ES-12 H + DIN 2080 pneumatic clamping is the full-option version of the basic UWF 90-1270, sized for mechanical workshops and production departments that require maximum productivity in tool changes and precision in machining. Distinctive features: the 3-axis digital display ES-12 H with 0.005 mm resolution replaces manual vernier readings on graduated scales, significantly reducing setup times and positioning errors. The DIN 2080 pneumatic clamping system with M16 drawbar replaces manual key clamping, reducing tool change time from 30-60 seconds to 5-10 seconds: a crucial feature for series production with frequent tool changes. The machine is equipped with both vertical and horizontal spindles with ISO 40 taper for interchangeable use (standard vertical milling, horizontal milling for long grooves and profile machining). In Krollit customers' workshops, the UWF 90-1270 is chosen by mechanical workshops with repetitive production of unique parts and small series, technical schools and professional training workshops, prototyping departments, and equipment and mold construction workshops.
Its place in the Bernardo range
The Bernardo UWF universal milling machine range is organized by table size and features: UWF 80 E and UWF 80 E Vario (compact table) for craft workshops; UWF 90 V and UWF 90 V Pneumatico (medium table) for professional workshops; UWF 90-1270, UWF 90-1270 with pneumatic clamping, UWF 95 N, UWF 110, and UWF 150 for industrial workshops with progressively larger machines.
The UWF 90-1270 configuration with DRO ES-12 H + pneumatic clamping is the complete accessory version of the basic UWF 90-1270: same mechanical characteristics (table, spindles, travels, motors) but with productive accessories included in the standard supply instead of being purchasable separately. The additional cost compared to the basic UWF 90-1270 is justified for workshops with regular production: the DRO ES-12 H and pneumatic clamping are rarely replaced after installation, so including them in the standard supply reduces the total investment cost. For workshops with occasional use, the basic UWF 90-1270 without accessories is significantly more economical, and accessories can be purchased separately when needed.

Frequently Asked Questions
What is the difference between the basic UWF 90-1270 and this version with pneumatic clamping?
Same mechanical characteristics (table, spindles, travels, motors, weight) but with productive accessories included: the 3-axis DRO ES-12 H replaces manual vernier readings, the DIN 2080 pneumatic clamping system replaces manual key clamping, reducing tool change times from 30-60 seconds to 5-10 seconds.
For workshops with regular production of small series (over 50 tool changes per day), the additional cost of the complete configuration pays for itself in 6-12 months of use. For workshops with occasional use or infrequent tool changes (under 10 per day), the basic UWF 90-1270 without accessories is more economical, and accessories can be purchased separately only when needed.
Does the pneumatic clamping system require a compressor?
Yes. The DIN 2080 pneumatic clamping system requires compressed air with a minimum pressure of 6 bar and adequate flow to activate the drawbar clamping cylinder. For workshops without an existing compressor, a separate industrial compressor must be purchased (typical cost €800-€3,000 for suitable models).
The workshop's network pressure must be stable during clamping operation: pressure drops (caused by simultaneous use of other pneumatic tools) can compromise the drawbar's grip, risking tool damage and injury. For workshops with intensive pneumatic use (painting, sandblasting, screwdrivers), a dedicated compressor for the milling machine or an additional accumulator tank is recommended.
What exactly does the 3-axis DRO ES-12 H measure?
It measures the absolute and relative positions of the X (longitudinal table travel), Y (transversal table travel), and Z (vertical spindle travel) axes with a resolution of 0.005 mm. It replaces manual vernier readings on graduated scales, reducing reading errors and setup times.
Standard DRO functions: absolute vs. relative position (zeroing for workpiece reference), inches vs. mm, integrated calculator, storage of useful positions (typically 100-200 points), repositioning function after interruption. For complex productions with multiple drilling/milling positions, the DRO reduces setup times by 2-3 times compared to working with manual scales. The 0.005 mm resolution is sufficient for most standard mechanical machining; for higher precision machining (below 0.01 mm), a grinding machine or a CNC milling machine is required.
Is the machine a CNC milling machine?
No. The UWF 90-1270 is a manual milling machine with automatic feeds on the X and Y axes and a positioning motor on the Z-axis. The DRO ES-12 H is a measuring tool, not a numerical control: the operator manually performs movements following a machining cycle.
For CNC milling (automatic execution of G-code programs), dedicated milling machines with numerical control (Siemens, Fanuc, Heidenhain) are required, and their cost is significantly higher (typically €50,000-€200,000 for industrial models). The UWF 90-1270 with DRO offers an intermediate level: the DRO accelerates manual machining, but the operator must be present. For workshops with production of unique parts or small series with complex cycles, this level is correctly sized; for high volume production, a CNC milling machine is the correct choice.
Can the vertical and horizontal spindles be used simultaneously?
No. The spindles are alternative: the operator configures the machine for vertical machining (tool in vertical spindle, horizontal spindle stopped) or horizontal machining (tool in horizontal spindle, vertical spindle stopped). Changing the configuration typically takes 5-15 minutes.
The use of the horizontal spindle is typical for long grooves (on the surface of large workpieces) and for profile machining that requires disc cutters. The horizontal spindle speed is lower (1,300 vs. 1,750 rpm) but the torque is higher: correctly sized for large diameter disc cutters that require high torque. For workshops specializing in standard vertical milling, the horizontal spindle is rarely used; for workshops with a variety of machining operations, the availability of both is an essential feature.
