For over three decades we have been producing standard and special boring heads for companies around the world.
We provide comprehensive service: design and consulting from highly qualified engineers, fast production, warranty and post-warranty service.
We guarantee the highest quality boring heads on the market. The production technology and premium materials used by Accurate Group significantly extend the life of the boring heads and reduce the load on the components cooperating with the head.
The gears of multi-spindle boring heads are made of hardened steel, the teeth are ground and helical gears are used, which ensures greater transmission force and quiet operation. Very high precision of the gears means low resistance of these elements, which in turn reduces the load on the driving gear.
The bodies of Accurate Group boring heads are made of the highest quality, carefully selected aluminum alloy, thanks to which they dissipate heat much better than steel housings and have a lower own weight..
Ground spindles are made of high-strength steel.
Rilesa easy-fit mounting – the innovative use of a rotating mounting ring allows for quick, safe and convenient installation of the boring head on the machine.
The highest quality materials, high precision of individual elements, very low resistance of gears, reduced weight and lower operating temperature of our boring heads significantly extend the interval of machine repairs.
Accurate Group boring heads are covered by a 12-month warranty against material defects.
What are boring heads?
Boring heads are specialised machining units or attachments for drilling machines and other machine tools, including CNC machining centres, designed to hold and drive cutting tools. Depending on their design and the tools used, they enable drilling, counterboring, countersinking, reaming, tapping or milling operations.
Multi-spindle boring heads have two or more working spindles and enable holes to be drilled simultaneously in a specified pattern during a single machining cycle. They reduce the time required to produce repeated hole patterns and are therefore used in series production.
Standard linear multi-spindle boring heads
We produce boring heads for conventional and CNC drilling machines, boring heads with standard spacings and any configuration of spindles and mountings. Our offer includes all typical boring and tapping head solutions. We can adapt the height of spindles and type of mounting to the customer's needs. We supply boring heads for machines in the wood, furniture, metal and glass industries. We guarantee the availability of spare parts for all of the produced boring heads.
- We are one of the few companies on the market to offer heads for processing metal, glass, stone and plastics.
- The highest quality of the materials used and the very high precision of our boring heads enable operation at high rotational speeds of up to 6,500 rpm.
- We apply selected lubricants and special pastes, thanks to which Accurate Group boring heads require little maintenance.
Custom multi-spindle boring heads
We also make boring heads according to individual orders in accordance with the submitted specifications. We produce special boring heads for wood and metal, as well as for glass, stone and plastics. Drills, taps, milling cutters and other tools can be installed to the spindles using a classic holder or quick chuck.
For over 30 years, our technical advisors and highly qualified engineers have been designing dedicated multi-spindle boring heads for many types of industries and for companies from around the world, including international corporations.
- We will make any type of multi-spindle boring head in any shape and with any spindle distance.
- Accurate Group boring heads are covered by a 12-month warranty against material defects.
- You will receive support from a technical advisor, also in English.
Multi-spindle tapping heads
We manufacture multi-spindle tapping heads for producing internal threads simultaneously in several pre-machined holes. In series production of housings, covers and flanges, this solution reduces the number of positioning moves between holes and shortens the machining time per component.
We tailor the configuration to the machine and the component drawings. We select the number and spacing of the spindles, the mounting arrangement and the tap holders. We take into account the thread diameter, pitch and depth, the workpiece material and whether the holes are through or blind. Tapping requires the feed rate to be matched to the rotational speed of the taps and the thread pitch. To withdraw the taps, their direction of rotation must be reversed.
- When selecting tap holders, we assess the need for axial compensation to accommodate minor differences between the machine feed and the tap’s axial movement.
- We assess the need for overload protection to reduce the risk of tool breakage due to excessive torque.
- We provide technical advice, ensure spare parts availability and offer warranty and post-warranty service.
Multi-spindle milling heads
We manufacture multi-spindle milling heads for machining several areas of a component simultaneously. Depending on the configuration and the milling cutters used, they can be used for slot milling, pocket milling, face milling or edge chamfering. Machining with several tools simultaneously reduces the number of separate passes and shortens the machining time per component in series production.
During milling, the spindles also carry radial loads acting perpendicular to their axes. We therefore select the bearing arrangement, head mounting stiffness and cutter overhang to suit the anticipated loads. Proper spindle support and keeping tool overhang as short as possible reduce deflection and vibration that affect machining accuracy and surface finish.
- We select the number and spacing of the spindles, their directions of rotation and the tool holders to suit the component drawings and the capabilities of the machine tool.
- We use ground helical gears made from hardened steel to ensure smooth power transmission and quiet operation of the gear train.
- The aluminium housing helps dissipate heat from the gear train and reduces the weight of the head.
Multi-spindle chamfering heads
We design and manufacture multi-spindle chamfering heads for machining multiple edges simultaneously in a single machine cycle. Depending on spindle spacing and the tools used, these systems can perform hole chamfering, external edge chamfering and deburring simultaneously. In series production – for example, of housings, covers or flanges – they eliminate the need for repeated positioning and tool changes, dramatically reducing the machining time per component.
We select the tooling – including countersinks and solid carbide or indexable chamfer mills – to suit the workpiece material, the required chamfer angle and access to the features being machined. Since meeting chamfer size tolerances depends directly on "Z" axis infeed accuracy, the heads allow precise, independent adjustment of each tool’s projection to compensate for deviations when the workpiece is located repeatably.
- We design the spindle configuration – including the number, spacing and type of spindles and the flange mounting system to suit the specific machine tool and manufacturing process documentation.
- The rigid gearbox construction minimises vibration, ensuring a high-quality surface finish and noticeably extending the life of the cutting edges.
- We provide comprehensive engineering support, covering cutting parameter selection, spare parts supply and authorised servicing.
