Application of the machine tool
TBI SDV-H gantry milling machines are used for roughing and finishing of large workpieces with higher weight.
The gantry structure of the machine body is more stable than the classic C-shaped solution used in 3-axis CNC machining centers – thus, gantry milling machines are characterized by high rigidity, guaranteeing efficient machining and the possibility of deep cutting (AP) at simultaneous high feeds (F).
It should be noted that the TBI SDV-H series of gantry milling machines can machine workpieces longer than the machine’s X-axis travel. A two-stage gearbox giving high torque is standard equipment.
The use of angle heads allows machining on five sides.

The headstock base of the TBI SDV-H gantry milling machine has 4 Z-axis guideways mounted on the edges of the headstock , making it extremely resistant to vibration. Automation of the machining process and reduced set-up time is guaranteed by the headstock (changing heads looks similar to changing a tool from the stock).

To put the subject in a nutshell: the price of a CNC machine depends primarily on how it is built. The price consists of materials, components, equipment, human labor, brand. Leaving aside the issue of control ?
CNC machines from different manufacturers have quite similar technical solutions. Typically, discrepancies occur between size, length, weight, accuracy or visual aspects and brand recognition.

Over the years of work, we have learned one thing: how many customers, so many needs ? and we know how to identify them. That’s why we realize that one of the most nagging questions from customers is: ? “When will I get my machine tool?”. Although one would like to say ? “it depends? ? because it really does ? we are well aware that it is difficult to put such a date into any investment plan or take it into account when planning production.

In order to remain competitive in the market and increase the quality of their services, more and more companies are choosing to purchase a new CNC machine tool. However, it is often the case that not all customers want to commit a larger sum of money. In this case, they choose to take advantage of available forms of financing, particularly leasing. In that case, they commit funds only for their own contribution; the leasing company finances the rest. Learn more…

More favorable for tax purposes is the operating lease, the initial payment, the full lease payment and the expenses incurred on the leased object are included in the tax deductible expenses. The condition is that the contract is concluded for at least 40% of the depreciation period for the asset and that there is a limit on the determination of the final redemption value. VAT is added to each lease installment.

In the case of a finance lease, the entrepreneur becomes the owner of the CNC machine and makes monthly depreciation deductions, only the interest and all expenses incurred are charged to expenses. There are no restrictions on the contract term or residual value, while VAT is paid on the full value of the machine along with the first installment.

The standard financing period for the purchase of a CNC machine is 3 to 5 years, but it is possible to extend financing up to 7 years. Shortening an operating lease is more complicated. If it occurs before 40% of the normative depreciation period has elapsed, the regulations oblige the leasing company to sell the leased asset, at the market value confirmed by an appraiser’s valuation or at the outstanding value, whichever is higher.

There is no clear answer. Certainly obtaining financing through a CNC machine supplier can make the process easier. Significance will be given to the amount of the declared initial fee (minimum 20%), the assets of the company and the owner, the possibility of guaranteeing with private assets by the lessee or representative, the prospects of the company (experience of managers, contracts concluded, the amount of turnover.
