Machine tool: gantry milling and compounding center DMU 210 FD duoBLOCK®
Abstract: At present, the customer has 4 DMG milling and compounding center DMU 210 FD duoBLOCK® as a small production line.
Project highlights
· All the turning, milling, drilling, boring and other processing contents are completed twice in the front and back, the process is concentrated, the processing time is shortened, and the machining accuracy is improved.
· With DMG's tilting turning function, shorter shanks can be used, machining rigidity is guaranteed and accuracy is improved
· Thanks to the high precision of the machine tool, the coaxiality and accuracy of the key hole system are greatly improved.
· With DMG's special “L-shaped†probe solution, it is convenient to measure the diameter, width, etc. of the groove on the inner wall.
· The countertop is equipped with a radial T-shaped groove, which is equipped with DMG special jaws for easy part clamping.
Machine tool highlights
· Whether it's large tools or mold making, machinery, automotive, model, instrument manufacturing, or aerospace industry, DMU/C FD milling and turning complex machining centers will be able to show their talents as long as they are processed in large quantities.
· The gantry structure, which is most suitable for large workpiece machining, is designed as a machine tool to maximize the rigidity of the machine structure. At the same time, the thermal symmetrical structure has a liquid-cooled ball screw drive mechanism and has a cooling feed motor in all the shafts. The degree of durability is guaranteed to a certain extent.
· One-time clamping for milling/car composite machining
With only one clamping, it is possible to perform 5-sided (or) 5-axis milling and can perform turning operations with a maximum workpiece weight of 7 tons (DMU 340 FD). This composite machining solution not only reduces costs, reduces machining time, but also enables more flexible and ultra-precision machining. The new "turning" CNC rotary table uses a direct drive approach that combines turning and milling. This high-efficiency machining unit has a table speed of up to 250 rpm, a torque of 7,900 Nm or 10,800 Nm, a clamping torque of 7,390 Nm or 10,000 Nm, and the milling performance has never been better. In addition, the machine retains all the functions of a milling center, which is comparable to a pure milling machine.

Slightly different from the conventional spring is that the spring itself is irregular, there are bending and a large number of complex angle design and manufacturing technology is relatively more demanding, equipment is also a more demanding general computer winding because of winding angle, bending more, so slow production speed because of its complexity, the production and processing of special-shaped spring can often represent a company`s technical level.
Special-shaped Spring and conventional spring is slightly different from the spring is the ability to be irregular, bending and a large number of complex angle design
Common Spring is divided into: Compression Spring, Tension Spring, Torsion Spring. Special-shaped spring, special-shaped spring is mainly the existence of complex spatial angle, irregular bending and so on.
The adaptability of the special-shaped spring is very wide. Common such as cars, machinery, daily hardware products on.
Stainless Steel Spring wire 301,302 or 304 stainless steel springs made of stainless steel are not recommended when the temperature exceeds 260 degrees Celsius (500 degrees Fahrenheit) .
Metal string materials when the temperature exceeds 121 degrees Celsius (250 degrees Fahrenheit) , do not recommend the use of musical instruments metal string, wire-based spring.
