CNC short turned parts / precision turned parts with simple or complex geometries on state-of-the-art CNC short turning machines up to 60 mm (bar)/200 mm (chuck) diameter in complete machining.

The introduction and implementation of a quality management system at PreTec was confirmed by the successful certification to DIN ISO 9001 in April 2000. Internal and external audits monitor and guarantee compliance with and further development of this quality standard.

The machinery is characterised by its versatile applicability. Thanks to this, we remain able to deliver even in times of supply bottlenecks and therefore we can ensure our customers' just in time supply with parts.
With a total of 16 CNC-controlled lathes (some of them double spindle machines) in the areas of bar and chuck machines, we are able to master the whole range of machining processes in turning. We manufacture high-precision turned parts, in bar machines for diameters from 20 to 100 mm, and for chuck parts with diameters from 20 to 350 mm. Some of the lathes are equipped with powered tools (1 to 2 revolver and Y-axis) to manufacture complex components for our customers in the automotive industry, drive technology as well as mechanical engineering.

So that we can act even more flexibly, in 2005 a new hall for mechanical
processing was constructed on the ACE's premises. The hall is equipped
with cranes with a capacity of up to 35t and enables quick and
problem-free equipping of the machines. In this way, an optimal and
economical flow of materials is guaranteed. ACE has the most modern CNC
mobile lathes, CNC work centres and drilling and milling machines as
well as one of the most modern CNC deep hole drilling machines for the
processing of tube sheets up to 1,200 mm depth. The consistent use of
CNC technologies enables very high dimensional accuracy to be attained
for all produced parts. Through the networking of the individual
machines on the basis of CAM, ACE is able to produce efficiently and
economically.

The in-house specialist workshop for copper work and small parts guarantees international quality standards. This workshop also forms the basis for our high-quality apprentice training.
ACE has maintained the tradition of the in-house coppersmiths until this day and is thereby about to produce small parts, which have been individually adapted to customer requirements, in an uncomplicated way.

The company has its roots in a coppersmith's. ACE would like to continue
to uphold this tradition and operates a special workshop in which,
alongside copper, aluminium, iron and stainless steel are also
processed. The product portfolio comprises the repair and new production
of distillation units as well as other copper work such as copper

CNC turning is a manufacturing technology that involves precision machining by means of a computer programme controlled lathe. It uses the relative motion between a rotating workpiece and a fixed tool to remove material to form the desired geometry. Compared to traditional manual turning, CNC turning offers a higher degree of automation, accuracy and repeatability, and is suitable for the mass production of complex parts

Key technical parameters in CNC turning machining
The reasonable setting of key parameters directly affects the machining effect:
Spindle speed (n)
Determine the appropriate cutting speed (vc) according to the diameter of the workpiece and tool material, and the calculation formula is generally:
????=1000×????????/????×????
Feed (f)
Depends on the tool, material and machining requirements, usually in mm/rev. A suitable feed ensures surface quality and tool life.
Depth of cut
The thickness of material removed per cut, which can be appropriately large for roughing and needs to be reduced for finishing to ensure dimensional accuracy and surface quality.
Backstroke (width of cut)
According to the rigidity of machine tools and cutting tools, a reasonable amount of backstroke can improve productivity, but too large may affect the surface quality.

Our various processing technology main production products include: equipment spare parts, product shells, mechanical parts, chassis cabinet shells and so on. These products are widely used in intelligent security, 3C, automotive, medical, smart grid monitoring and other fields.

3. Cutting parameter settings
Speed and feed: It needs to be adjusted according to the hardness of the material and the type of tool. During precision machining, high speed is required with a small cutting step of 23.
Thermal stability impact: Insufficient preheating of the machine tool may lead to dimensional fluctuations (such as early processing errors of 5-6 threads), and it is necessary to stabilize the accuracy through a thermal machine.
4. Control system and operation
Program transfer: Supports transferring G-code from a USB flash drive, and the operation process includes standardized steps such as tool alignment and startup.
Emergency stop and limit: The external button can be configured with emergency stop, jog, and high/low speed switching functions. The limit signal needs to be designed to be normally closed to ensure safety.

CNC turning is a highly efficient machining process predominantly used for shaping cylindrical workpieces, although it can also handle square or hexagonal-shaped raw materials. At its core, CNC turning involves the use of a computer-controlled lathe that rotates the workpiece against various cutting tools. These tools trim and shape the material into the desired cylindrical form.
The uniqueness of turning machine lies in its versatility and precision, governed by different spindles and speed capabilities. This process can be performed on both vertical and horizontal setups, each catering to specific types of workpieces and machining requirements. There are two main types of machines: CNC Lathes, CNC Turning Centers.
